INTRODUCTION
1.
An open, vibrant internet is indispensable to
American life. But today’s internet
would not exist without
the
digital
advertising revenue that, as a practical
matter, funds
its
creation and expansion. The internet provides the public with unprecedented access to ideas,
artistic expression,
news, commerce,
and services. Content creators
span
every conceivable
industry; they publish diverse
material on countless websites that inform, entertain, and connect
society in vital ways. Yet the viability of many of these
websites depends on their ability to sell
digital advertising
space. Just as newspaper, radio, and television organizations
historically
relied
on advertising to fund their operations, today’s online publishers
likewise rely on
advertising
revenue to support their
activities and reach. But unlike
historical me
dia
advertising, today’s
online ads are bought
and sold in enormous volumes in mere fractions of
a second, using highly
sophisticated tools and automated exchanges that
more closely resemble a modern stock
exchange than an old-fashioned, bilateral contract
negotiation for newspaper
ad space.
2.
Website publishers
in the United States sell more than
5 trillion digital display
advertisements
on the open web each yearor more than 13 billion advertisements
every day.
The sheer volume of these online ads make the
offline advertisements
of yesteryear
pale in
comparison. To put these numbers in perspective, the daily volume of digital display
advertisements
grossly
outnumbers (by several multiples) the average number of stocks traded
each day on the New York Stock Exchange. The digital display
advertising bus
iness is also
lucrative.
Collectively,
these
advertisements
generate more than $20 billion
in revenue
per
year,
just for publishers based in the
United States.
3.
To meet this demand, sophisticated technological tools, informally
known as “ad
tech,” have developed to automate advertising
matchmaking between two key
groups:
website
1
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 6 of 153 PageID# 6
publishers and
advertisers.
1
These tools have evolved such that today, every time an internet user
opens a webpage with ad space to sell, ad tech tools almost instantly match that website
publisher with an advertiser looking to promote its products or services to the website’s
individual user. This process typically involves the use of an automated advertising exchange
that runs a high-speed auction designed to identify the best match between a publisher selling
internet ad space and the advertisers looking to buy it.
4. But competition in the ad tech space is broken, for reasons that were neither
accidental nor inevitable. One industry behemoth, Google, has corrupted legitimate competition
in the ad tech industry by engaging in a systematic campaign to seize control of the wide swath
of high-tech tools used by publishers, advertisers, and brokers, to facilitate digital advertising.
Having inserted itself into all aspects of the digital advertising marketplace, Google has used
anticompetitive, exclusionary, and unlawful means to eliminate or severely diminish any threat
to its dominance over digital advertising technologies.
5. Google’s plan has been simple but effective: (1) neutralize or eliminate ad tech
competitors, actual or potential, t hrough a series of acquisitions; and (2) wield its dominance
across digital advertising markets to force more publishers and advertisers to use its products
while disrupting their ability to use competing products effectively. Whenever Google’s
customers and competitors responded with innovation t hat threatened Google’s stranglehold over
any one of these ad tech tools, Google’s anticompetitive response has been swift and effective.
Each time a threat has emerged, Google has used its market power in one or more of these ad
1
Internet advertisers include businesses, agencies of federal and state governments, charitable
organizations, political candidates, public interest groups, and more. The money these advertisers
spend on digital advertising creates an important stream of revenue for websites to use in
creating, developing, and publishing website content.
2
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 7 of 153 PageID# 7
tech tools to quash the threat.
The result:
Google’s plan for
durable, i
ndustry-wide
dominance
has
succeeded.
6.
Google, a
single company
with pervasive conflicts of interest, now
controls:
(1)
the
technology
used by
nearly every major
website publisher to offer
advertising
space
for
sale;
(2)
the
leading tools used by
advertisers
to buy
that advertising
space; and (3)
the
largest ad
exchange
that matches publishers
with
advertisers
each time that
ad space is sold. Google’s
pervasive power over
the entire
ad tech
industry
has
been
questioned by its own digital
advertising executives, at least one of whom
aptly begged t
he question:
“[I]s there a deeper issue
with us owning the platform, the exchange, and a
huge network? The analogy would be if
Goldman or Citibank owned the NYSE.”
7.
By deploying opaque
rules that benefit itself and harm rivals,
Google
has wielded
its
power
across the ad tech industry
to dictate how
digital advertising is sold, a
nd the
very terms
on which its rivals can compete.
Google
abuses
its
monopoly
power to disadvantage
website
publishers and advertisers
who dare
to use
competing ad tech products
in a search for
higher
quality, or
lower cost,
matches. Google uses its
dominion ove
r
digital advertising technology
to
funnel
more transactions
to its
own
ad tech
products
where
it
extracts
inflated
fees
to line its own
pockets at the expense of
the advertisers
and publishers
it purportedly serves.
8.
Google’s anticompetitive behavior has
raised barriers to entry to artificially
high
levels,
forced
key competitors
to abandon
the market
for ad tech tools, dissuaded
potential
competitors
from joining the
market,
and
left
Google’s
few
remaining competitors
marginalized
and unfairly disadvantaged. G
oogle has thwarted meaningful competition and deterred
innovation in the digital advertising industry, taken
supra-competitive
profits for itself, and
3
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 8 of 153 PageID# 8
prevented
the free market
from
functioning
fairly
to support the interests of
the advertisers and
publishers who make today’s powerful internet possible.
9.
The harm is clear: website creators earn less, and advertisers pay more, than they
would in a market
where unfettered competitive pressure could discipline prices and lead to more
innovative ad tech tools
that would ultimately result in higher quality
and lower cost transactions
for market participants. And this conduct hurts all of us because, as publishers make less money
from
advertisements, fewer publishers are able to offer internet content without subscriptions,
paywalls, or alternative forms of monetization.
One troubling, but revealing, statistic
demonstrates the point: on average, Google
keeps
at least
thirty
centsand sometimes
far
more—of
each
advertising
dollar
flowing f
rom advertisers to website publishers through
Google’s
ad tech
tools. Google’s
own
internal documents concede
that Google
would earn far
less in a competitive market.
10.
The United States
and Plaintiff States bring this action for violations of the
Sherman Act to halt Google’s
anticompetitive scheme, unwind Google’s monopolistic grip on
the market, and
restore
competition to digital advertising.
II.
NATURE
OF THIS ACTION
11.
The seeds for
Google’s
eventual
march toward a
monopoly
in ad tech
were sown
in the early 2000s, when it
capitalized on its
well-known search engine to start a profitable
search
advertising business. In 2000, Google launched Google Ads
(then called AdWords
2
), a
tool that allowed businesses to buy advertisements that could be seen by Google search users
right alongside Google’s popular search engine results. Businesses quickly learned the power of
2
Over the period addressed by the Complaint, Google has renamed its ad tech products a number
of times and has either shifted certain functions between products or combined its products in
ways intended to obscure Google’s dominance across the ad tech stack.
4
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 9 of 153 PageID# 9
this
instantaneous, highly-targeted
advertising
technique,
and
they
flocked to Google Ads
as a
result.
12.
By the early 2000s, Google realized that these
same advertisers
would buy
digital
advertisements
on third-party websites
as well. S
o Google
stepped in to profit (as a middleman)
on digital advertising transactions having nothing to do with Google or its
search engine
by
creating
an advertiser ad tech tool
for Google Ads’ customers
that wanted
to buy ad space on
third-party websites.
13.
But Google
was not satisfied with its dominance on the
advertising
side of the
industry
alone; Google
devised a plan to build a
moat around the emerging ad tech industry by
developing a
tool that would be used by website
publishers
as well.
14.
Google
sought to develop an ad tech tool called a publisher ad server
that
publishers
would use
to manage their
online advertising sales. Google recognized that
because
publisher ad servers set the rules for how and to whom publisher advertising opportunities are
sold, ow
ning a publisher
ad server was key to having visibility into, a
nd control over,
the
publisher side
of digital advertising.
By controlling the
publisher
ad server
on the other end of
the transaction, Google
could further entrench its
advertiser
customer
base
by giving advertisers
access to more advertising opportunities and pushing
more transactions
their way.
15.
Of course,
by becoming the dominant player on both sides of the digital
advertising industry, Google
could
also
play both sides against the middle. It
could c
ontrol both
the publishers
with
digital ad space to
sell,
as well
as the
advertisers who want to buy that space.
With influence over advertising transactions
end-to-end, Google realized it could
become “the
be-all, and end-all location for all ad serving.”
The
outsized
influence it
could obt
ain by having a
dominant position on bot
h sides of the industry
would give
Google the ability to charge
supra-
5
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 10 of 153 PageID# 10
competitive fees
and also enjoy
an
abiding dominance sufficient
to exclude rivals
from
competition. Google would no longer have to compete on the merits; it could simply set the rules
of the game to exclude rivals.
16.
The only problem with Google’s plan was that Google’s publisher ad server failed
to gain traction in the industry. So, Google
pivoted to
acquiring
the market-leading publisher ad
server from an
ad tech firm called
DoubleClick. In early 2008, Google
closed its acquisition of
DoubleClick for over $3 billion. Through the
transaction, Google acquired a publisher ad server
(“DoubleClick for Publishers” or “DFP”), which had a 60% market share
at the time. It
also
acquired
a nascent
ad exchange
(“AdX”) through which digital advertising space could be
auctioned. The DoubleClick acquisition vaulted Google
into a
commanding position over
the
tools publishers use to sell advertising opportunities, complementing
Google’s existing tool for
advertisers, Google Ads, and set the stage for Google’s later exclusionary conduct
across the ad
tech industry.
17.
After the DoubleClick acquisition, Google enhanced and entrenched DFP’s
already-dominant market position. Google
internally
recognized that publisher ad servers
are
“sticky” products, meaning that publishers rarely
switch because of the high costs and risks
involved. As
DoubleClick’s former
CEO observed, “Nothing has such high switching costs. . . .
Takes an act of God to do it.” Thus, in order to lock more publishers into DFP and to reinforce
its stickiness, Google forged an exclusive link between Google
Ads
and
DFP through the
AdX
ad exchange. If publishers wanted access to exclusive Google Ads’ advertising demand, they had
to use Google’s publisher ad server
(DFP)
and
ad
exchange
(AdX), rather than equivalent tools
offered by Google’s
rivals. In effect,
Google
positioned itself to function simultaneously
as
buyer, seller, and auctioneer of digital display
advertising.
6
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 11 of 153 PageID# 11
18.
Google’s
strategy paid off. This arrangement
has
had a profound effect on the
evolution of
digital
advertising. First, it tilted the industry in Google’s favor, driving publishers
to adopt and stay on Google’s
DFP
publisher ad server
in order to have access to Google
Ads
advertiser demand. Second, it
cut off the possibility that Google Ads’
advertiser spending could
sustain, or encourage the
entry of, a rival ad exchange or publisher ad server by providing c
ritical
advertising demand. For
the vast majority of
webpage
publishers, this arrangement made DFP
the only realistic publisher ad server option. Indeed, by 2015, Google estimated
that
DFP’s
publisher
ad server
market
share had grown to a remarkable 90%. Googles durable monopoly
over the publisher ad server market
has
allowed it to avoid innovation and competition by
controlling
the very rules
by which the
game is played. As a result, other publisher ad servers
have left the market
altogether, refocused on related
markets, or faded into insignificance; no
new publisher ad servers
have entered
the market.
19.
Around
the same time
that
Google
tied
its
exclusive Google Ads
advertiser
demand to its publisher ad server
(DFP)
through AdX,
Google
took two additional steps to make
it more difficult for rivals to compete.
20.
First, Google configured Google
Ads to bid on Google’s
AdX ad exchange in a
way that actually
increased
the price of advertising, to the benefit of publishers and the detriment
of Google’s own advertiser customers. As one Google
employee observed, Google
Ads was
effectively sending a “$3bn
yearly check
[to publishers]
by overcharging our advertisers to
ensure we’re strong on the pub[lisher] side.”
In the short-term, this conduct
locked publishers
into Google’s
publisher
ad server
by providing them
a steady
stream of
intentionally-inflated
prices for certain
inventory,
at the cost of Google’s own advertiser
customers. B
ut in the long
run, Google’s actions harmed publishers
as well
by driving out
rival publisher ad servers
and
7
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 12 of 153 PageID# 12
limiting competition in the publisher ad server market. In effect, Google
was robbing from Peter
(the advertisers) to pay Paul (the publishers), all the while collecting a hefty
transaction fee for
its own privileged position in the middle. T
his conduct turned
the entire purpose
of the digital
advertising industry
on its head. Rather than
helping to
fund website publishing, Google
was
siphoning
off
advertising dollars for itself through the imposition of
supra-competitive
fees
on its
platforms. A
rival publisher ad server
could not compete with Google’s inflated ad prices,
especially without access to Google’s captive
advertiser demand from Google Ads.
21.
Second,
Google used its captive advertiser demand to
thwart legitimate
competition by
giving
its AdX ad exchange
an a
dvantage over other
ad exchanges through
a
mechanism known as
dynamic allocation. Dynamic allocation
was a means by which
Google
manipulated its publisher ad server to give
the
Google-owned AdX (and
only AdX) the
opportunity to buy publisher inventory before it was offered to any other
ad exchange, a
nd often
to do so at artificially low prices. Google
also
programmed
DFP, its
publisher ad server, t
o
prevent
publishers
from
offering
preferential terms to other ad exchanges or allowing
those
exchanges to operate i
n the same way
with DFP.
Google
knew
that dynamic allocation
would
inevitably
steer advertising transactions
away from rivals, denying them critical scale needed to
compete, and would advantage
AdX,
where Google could extract the largest fees.
Google’s
scheme p
redictably reinforced publishers’ dependence on both AdX
and DFP. P
ublishers
were
effectively precluded from using rival ad servers
or ad exchanges that might better suit their
needs
while Google
was
given a free pass from having to compete on the merits with those
rivals.
22.
By at least
2010, other ad tech companies
had
recognized that Google’s platforms
were not working in the
best interest of publishers, a
nd they attempted to develop innovative
8
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 13 of 153 PageID# 13
technologies to introduce more competition. Some companies began offering “yield
management”
functionality that helped publishers identify
on a real-time basis
better prices for
their inventory outside of Google’s products. Google recognized
that yield managers posed a
major threat to the increasingly closed system Google sought to establish, in which
only
its ad
exchange was able to
compete based on
real-time pricing.
So, in response, Google
employed a
familiar tactic: acquire, then extinguish, any
competitive threat.
23.
In 2011, Google
acquired
AdMeld, the leading
yield manager,
folded its
functionality
into Google’s existing products, a
nd then
shut down its
operations
with non-Google
ad
exchanges and
advertiser tools. Google
soon thereafter
changed
its AdX contract terms to
prohibit publishers from using any other platform
(such as
another
yield manager) that would
force
AdX to compete in
real
time with other ad exchanges. As
a Google
product manager
wrote:
“Our
goal should be
all or nothing
use AdX as
your [exchange] or don’t
get access to our
[advertising]
demand.”
Unsurprisingly, this unabashed, a
nticompetitive conduct had a profound
effect on the market, denying rival ad tech competitors the scale necessary to compete and
depriving publishers the benefits of free market competition and real choice.
24.
Not long after, in 2013, Google launched Project Bernanke, a
secret
scheme to
manipulate the bids that Google
Ads submitted into Google’s
ad exchange, AdX, in order to win
more competitive transactions and solidify AdX’s dominance
in the industry.
Project Bernanke
allowed
Google
to suppress competition by
preventing rival
ad
exchanges
from achieving the
transaction volume and scale necessary to compete. Unless another ad e
xchange developed both
its own unique source of
captive advertiser demand—where it could potentially
manipulate
advertiser bids—and a widely-adopted publisher
ad server—where it could see the same
advertising inventory
and bid data as Google—competition
on the same terms as Google was
9
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 14 of 153 PageID# 14
nearly impossible. Once again, by controlling all sides of the ad tech industry, Google has been
able to manipulate the system in ways unique to itself so that, in the end, it did not have to
compete on the merits for customers and volume.
25. Publishers and competing ad tech providers, increasingly wary of Google’s
bullying behavior, have continued to look for new ways to circumvent Google’s dominance.
Between 2012 and 2013, market participants began using a technique called “header bidding
as a partial workaround to Google’s self-preferential algorithms and ad tech restrictions. As one
Google employee explained, “Publishers felt locked-in by dynamic allocation in [Google’s ad
server] which only gave [Google’s ad exchange] the ability to compete, so HB [header bidding]
was born.”
26. Publishers used header bidding to take back some degree of power over their own
advertising transactions. They inserted header bidding computer code onto their own websites to
allow non-Google advertising exchanges an opportunity to bid for advertising inventory before
Google’s hard-coded preferences for its own ad exchange were triggered. Header bidding
allowed publishers to ensure that multiple advertising exchanges—not just Google’s AdX—
could bid on their inventory, thereby increasing the chances that they could find the best match.
27. Google has refused to tolerate this new form of competition, even though it has
acknowledged in internal emails that header bidding had grown naturally out of Google’s being
“unwilling[] to open our systems to the types of transactions, policies and innovations that
buyers and sellers wish to transact.” Indeed, Google privately admitted that “header bidding and
header wrappers are BETTER than [Google’s platforms] for buyers and sellers,” and that
increased competition between AdX and publishers using header bidding would increase
publisher revenues by 30 to 40%, and would provide additional transparency to advertisers. Not
10
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 15 of 153 PageID# 15
only would header bidding enable rival exchanges to compete more effectively against Google’s
ad exchange, it might also allow them or others to enter the publisher ad server market if Google
no longer had exclusive access to unique advertiser demand.
28. Google executives described header bidding as an “existential threat.” They
worried that wider adoption of header bidding practices could lead to Google’s ad exchange
having to compete with other ad exchanges on a level playing field, where Google could no
longer set the rules in its own favor. If that were to happen, those rival ad exchanges might
actually succeed in eroding, or even breaking up, Google’s advertiser juggernaut, and the entire
industry could be opened up for competition. Google feared the worst: the entire moat of
anticompetitive protections that Google had built around the ad tech industry could be breached.
29. Faced with this “existential” threat, Google sought to stem the rising tide toward
header bidding by promoting a Google-friendly analog of header bidding that Google
deceptively titled Open Bidding.” Google has promoted Open Bidding as an answer to the
industry’s call for wider participation by rival ad exchanges and increased competition. In fact,
Open Bidding was a Trojan Horse that Google used to further cement its own monopoly power.
30. As a condition to using Google’s Open Bidding, Google has required that
publishers and participating ad exchanges give Google visibility into each auction (including
how rival exchanges bid), allow Google to extract a sizeable fee on every transaction (even
where another exchange won), and limit the pool of advertisers allowed to bid in the auctions. In
doing so, Google’s ad exchange has retained a guaranteed seat in every auction, regardless of
whether Google’s ad exchange offers the best match between advertisers and publishers.
31. Google also sought to co-opt what it perceived to be its two biggest threats
(Facebook and Amazon) into Open Bidding. In internal documents, Google concluded that while
11
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 16 of 153 PageID# 16
it “[c]annot avoid competing with FAN [Facebook],” it could, through a deal with Facebook,
“build a moat around our demand.” Internal documents recommending a deal with Facebook
revealed Google’s primary motive: “[f]or web inventory, we will move [Facebook’s] demand off
of header bidding set up and further weaken the header bidding narrative in the marketplace.”
Thus, for these reasons, Google ultimately agreed to provide preferential Open Bidding auction
terms to Facebook in exchange for spend and pricing commitments designed to push more of
Facebook’s captive advertiser spend onto Google’s platforms. Google sought to head off
Amazon’s investment in header bidding technology with a similar offer, albeit without the same
success.
32. Google also adjusted its auction mechanisms across its ad tech products to divert
more transactions to itself and away from rivals that might deploy header bidding. On the
publisher side, Google allowed AdX—and only AdX—to change its auction bid by altering
Google’s own fee after seeing the price to beat from another exchange.
33. On the advertiser side, Google first considered outright blocking its advertiser
buying tool from buying inventory made available via header bidding. The goal:dry out HB
[header bidding].” When Google decided that strategy would be too costly for Google, it pivoted
to a different and more insidious strategy with the same effect.
34. Google recognized that “instead of stop[ping] bidding on HB [header bidding]
queries, we could bid lower on HB queries,” and win the same impressions on Google’s ad
exchange instead. No rival exchange was in a position to compete with this strategy because no
rival had the scale necessary to compete against the industry giant, especially considering the
built-in advantages that Google afforded its own ad exchange and publisher ad server. Google,
and Google alone, had control over both the leading source of advertiser demand and the
12
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 17 of 153 PageID# 17
dominant publisher ad server. So, Google programmed its advertiser buying tool to advantage its
ad exchange.
35. Google’s bidding strategy on header bidding transactions proved remarkably
effective in stunting the growth of header bidding, but Google still worried that its moat was not
fully secure. Google learned that some publishers were using price controls within Google’s own
DFP publisher ad server to sell advertising inventory to rival exchanges outside of Google’s
closed-wall system, even in instances where Google’s own AdX exchange had offered to pay
more for the inventory. Publishers did so for a variety of reasons, including considerations
related to ad quality, volume discounts, diversification of demand sources, data asymmetries, or
other factors.
36. When Google identified this threat, it simply removed the feature from DFP and
instead imposed competition-stifling Unified Pricing Rules. Under these new rules, publishers
could no longer use price floors to choose rival exchanges or other buyers over AdX or Google
Ads, no matter the reason. Google effectively took away their own customers’ right to choose
what buyer or ad exchange best suited their needs. In doing so, Google once again bought itself a
free pass on competition.
37. Google’s exclusionary, anticompetitive acts have severely weakened, if not
destroyed, competition in the ad tech industry. In decision after decision, year after year, Google
has repeatedly done what was necessary to vanquish competitive threats, including by enacting
policies that took choices away from its own customers. And despite what Google may claim, it
did not do so to protect the privacy interests of Google users. Indeed, Google intentionally
13
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 18 of 153 PageID# 18
exploited its massive trove of user data to further entrench its monopoly across the digital
advertising industry.
3
38. Due to Google’s conduct, ad tech tools that should have evolved to better serve
website publishers and advertisers in a competitive environment have instead evolved to serve
the interests of Google alone, to the detriment of Google’s own customers. The results have been
catastrophic for competition. Today, major website publishers have a single viable choice for
publisher ad servers—Google’s DoubleClick for Publishers. Google routes transactions from its
publisher ad server to its more expensive ad exchangeAdXand away from rival platforms,
all of which are less than a quarter of AdX’s size.
39. Advertisers and publishers, the key players in this market, have had scant
visibility into the scope and extent of Google’s anticompetitive conduct. As the lone conflicted
representative of both buyers and sellers, Google has created a deliberately-deceptive black box
where Google sets the auction rules to its own advantage. Diminished competitive pressure has
reduced Google’s incentive to innovate, and Google’s control of these key ad tech tools has
inhibited rivals’ ability to introduce efficiency-enhancing innovations. Publishers and advertisers
suffer from reduced competition for both ad tech products and advertising inventory. Google’s
conduct undermines the very purpose of digital advertising in the first place: to achieve optimum
terms and pricing for digital advertisements so website publishers can continue to serve their
3
At the time of the DoubleClick acquisition, Google’s privacy policies prohibited the company
from combining user data obtained from its own properties, e.g., Search, Gmail, and YouTube,
with data obtained from non-Google websites. But in 2016, as part of Project Narnia, Google
changed that policy, combining all user data into a single user identification that proved
invaluable to Google’s efforts to build and maintain its monopoly across the ad tech industry.
Over time, Google used this unique trove of data to supercharge the ability of Google’s buying
tools to target advertising to particular users in ways no one else in the industry could absent the
acquisition of monopoly—or at least dominant—positions in adjacent markets such as Search.
14
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 19 of 153 PageID# 19
vital purposes in society. Indeed, Google’s own documents show that Google has siphoned off
thirty-five cents of each advertising dollar that flows through Google’s ad tech tools:
Fig. 1
40. The cumulative impact of Google’s anticompetitive conduct is more than simply
the sum of each harm Google has caused. As new threats have arisen, Google has spread its
actions across wide-ranging ad tech products knowing the synergistic, multiplier effect that its
actions would have across the industry. Because Google has such a powerful hand in each aspect
of the ad tech industry, it alone has the power to use and deploy hidden levers to manipulate the
overall system to its advantage.
41. It is critical to restore competition in these markets by enjoining Google’s
anticompetitive practices, unwinding Google’s anticompetitive acquisitions, and imposing a
remedy sufficient both to deny Google the fruits of its illegal conduct and to prevent further harm
to competition in the future. Absent a court order for the necessary and appropriate relief, Google
will continue to fortify its monopoly position, execute its anticompetitive strategies, and thwart
15
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 20 of 153 PageID# 20
the competitive process,
thereby raising
costs, reducing c
hoice, and stifling innovation in this
important industry.
III.
DISPLAY ADVERTISING
TRANSACTIONS
42.
When an internet user opens a website,
a complex series of transactionsnearly
instantaneous and invisible to the user—determines which ad to show to that user in each
available ad space on the
webpage. The set of technological tools that connect
website publishers
selling
advertising opportunities to the advertisers
wishing to buy those advertising opportunities
(“ad inventory”)
is referred to as
ad tech. Below is a schematic depicting
some of the important
ad tech tools used in online digital advertising:
Fig. 2
A. How Ad Tech Tools Work
4
43. The content creator or owner of a website is called a publisher. Each website can
be programmed by its publisher to create slots where ad s can be displayed. A graphical ad
4
The process described herein governs the sale of display ads on the “open web,” meaning
websites whose inventory is sold through ad tech intermediaries that offer inventory from
16
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 21 of 153 PageID# 21
displayed on
a website that is
viewed in an internet browser is called
a display ad. A display ad
may
contain images, text, or multimedia. A single
display
ad shown to a single user
on a single
occasion
is called
an
impression.
44.
An ad tech transaction
begins when a user opens a
website. While the website’s
content loads, the
website uses
a
publisher ad server
to select which ads
will fill each ad slot on
the page. The publisher ad server is an ad tech tool that
evaluates
potential
ads from different
advertising sources
and
applies
a
decision-making logic
to
determine which ad will be displayed
to the user opening the website. Since 2008, Google
has owned t
he industry’s leading publisher
ad server, Google Ad Manager, which is often still referred to by its former name,
DoubleClick
for Publishers (DFP”).
45.
For a typical medium-to-large website, the publisher
ad server first determines
whether the ad spaces
on the
webpage
opened by the user have
already
been sold to a specific
advertiser directly by the
publisher. Such
direct sales
result from one-on-one negotiations
between
website publishers and advertisers
and typically involve
premium
ad placements (e.g.,
ads at the top of a webpage) that command the
highest
prices
from advertisers.
For any ad space
not filled through
direct sales, the
publisher
ad server then tries to sell the ad
space through
indirect sales channels.
Indirect sales
allow
publishers
to sell
remaining or “remnant” ad space
multiple websites. Some websites, especially social media companies like Facebook and
Snapchat, operate under a different “closed web” (or “walled garden”) model in which inventory
is sold directly to individual advertisers using a proprietary tool employed by that website. Other
types of advertising distinct from open web display advertising include search ads (e.g.,
sponsored results in a search engine), video ads (e.g., commercials that play before, during, or
after a streaming video), and mobile app ads (e.g., ads shown within a game or other non-
browser app downloaded from an app store to a user’s mobile device). The focus of this
Complaint is on Google’s anticompetitive conduct in the market for open web display
advertising transactions.
17
5
For both direct and indirect sales, ad impressions are generally priced on a CPM basis,
referring to cost-per-thousand (in Latin, “mille”) per impression. For example, an impression
with a $1 CPM would cost $0.001, or one-tenth of a cent.
6
Because the publisher ad server historically transmitted this information to the ad exchange, the
publisher ad server controlled what information was sent to prospective advertisers and in what
form.
7
Information concerning t he user’s location and browsing history can be gleaned through
“cookies” set in place by the user’s web browser. These cookies allow the web browser to collect
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 22 of 153 PageID# 22
(i.e., space not sold through direct sales). Many website publishers, especially smaller ones, only
sell ad space through such indirect sales.
5
46. Indirect sales are typically made via a series of interactions between ad tech tools.
These technologies allow website publishers and advertisers to transact through lightning-fast
automated processes, known as programmatic buying. Today, most programmatic transactions
take place on an ad exchange. An ad exchange (sometimes called a supply-side platform or SSP)
is a software platform that receives requests—often from a publisher ad server—to auction ad
impressions on a particular webpage. The ad exchange solicits bids on the impression from
advertiser buying tools, chooses the winning bid, and transmits information on the winning bid
back to the publisher ad server. Google presently owns the industry’s leading ad exchange, called
AdX (now packaged as part of Google Ad Manager).
47. When a publisher ad server sends an auction request to an ad exchange, the
publisher ad server provides certain information about the impression for sale. This can include
information about the website itself, the ad space on the webpage (e.g., where the ad is placed),
and the user that will view the impression.
6
After receiving this information from the publisher
ad server, the ad exchange may supplement the information with any additional information the
ad exchange might independently have about the user viewing the ad, including information
about the user’s browsing history, location, and age.
7
The ad exchange then transmits the bid
18
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 23 of 153 PageID# 23
request, along with information gathered
about the user and the website,
to
various
advertiser
buying tools, described below. The detailed information c
oncerning the user’s location and
browsing
history is highly
valuable to advertisers
because it helps
advertisers
assess the value of
the
particular
impression to its
overall
advertising campaign. For example, if
the
information
tells a
particular
retail advertiser
that the user had previously browsed that retailer’s website but
did not complete a sale, then that retailer may be
willing to pay a premium for the particular
impression.
48.
Advertisers receive and respond to bid requests using
advertiser buying tools.
These advertiser buying tools assist advertisers with connecting to ad exchanges, selecting
impressions to bid on, submitting bids, and tracking
the purchased impressions
against the
advertiser’s advertising campaign goals.
49.
Large
ad buyers, such as
major ad agencies or large businesses, frequently
use a
type of
advertiser buying tool called a
demand side platform. Demand side platforms provide
sophisticated and customizable tools that
allow
the ad agency or business
to manage their
advertising purchases. Advertisers using
demand side platforms
have
extensive control over
where
and how they bid for ad inventory. They often use their own data, or
data purchased from
other entities, to target particular users
for their
ad
campaign.
Google owns the United States’
leading demand side platform, Display & Video 360 (“DV360”).
50.
Smaller advertisers
often
rely on
a type of advertiser
buying tool
with fewer,
simpler options
that are less customized. These advertiser buying tools
are called
advertiser ad
information about a user’s internet location and browsing history which can then be passed
along, or sold, to interested parties.
19
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 24 of 153 PageID# 24
networks.
8
Today, most ad networks bid for and buy advertising space on an impression-by-
impression basis, submitting bids alongside other ad networks and demand side platforms.
Advertiser ad networks offer a self-service, easy-to-use technology solution, which as a practical
matter is the only viable option for smaller advertisers, advertisers that prefer a simple “hands-
off” approach, or advertisers that need the ad network’s targeting data to buy ads effectively.
Google offers the industry’s leading ad network, Google Ads.
51. Most ad networks, including Google Ads, are a “black box” to advertisers.
Advertisers have almost no control over the process by which the ad network bids for
impressions. Nor do the networks provide advertisers with information about how or why the
network bids for particular impressions on particular websites at particular times. Most ad
networks charge advertisers primarily on a “cost per click,” or CPC basis. The advertiser thus
has no insight into how much the ad network spent to purchase a particular impression; the
advertiser is charged a fee only when an internet user clicks on the ad. Google’s ad network,
Google Ads, sets this fee based on the actual cost incurred to buy advertising inventory plus a
markup. This prevents Google’s advertising customers from knowing how much Google is
charging them, over and above Google’s costs, for the inventory.
52. These ad networks are particularly important to businesses that do not have the
expertise, advertising budget, or targeting data required for a demand side platform to be a viable
option. Ad networks are also critical to website publishers. These ad networks are the only way
for publishers to reach and sell ad space to smaller businesses that rely exclusively or primarily
8
These advertiser networks are referred to as “networks” because they originally operated on a
network model whereby the ad network would agree to buy a portion of a publisher’s advertising
space in bulk at a pre-set price. The ad network would then distribute the publisher’s advertising
space among a network of advertisers. The prices charged to those advertisers were not
necessarily derived from the bulk price the network paid to acquire the space.
20
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 25 of 153 PageID# 25
on ad networks to buy ad space. Further, the type of advertising space these ad networks seek to
purchase from website publishers is often distinct from the advertising space sought by other
advertising tools. That is because the advertisers using these networks often have unique
advertising objectives. Further, these ad networks, and in particular Google Ads, have access to
unique user data that allow them to target very specific advertising opportunities.
53. The flow of display ad transactions through these platforms—collectively called
the ad tech stack—is depicted again below.
Fig. 3
54. The publisher ad server is referred to as the “sell-side.” The advertiser buying
tools are referred to as the “buy-side.” Impressions offered for sale by publishers are referred to
as publisher “inventory” and advertisers’ interest in buying impressions is referred to as
advertiser “demand.”
55. Whether the advertiser uses a demand side platform or an ad network as its
advertiser buying tool, the tool evaluates the bid request received from the ad exchange and, if
the impression meets the advertiser’s criteria (e.g., targeted audience, website category), the tool
21
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 26 of 153 PageID# 26
determines an amount to bid on the impression. Because each impression is filled within
fractions of a second while the website loads for the user, an advertiser could never evaluate each
impression individually. Instead, advertisers rely on these automated advertiser buying tools to
evaluate impressions and bid on their behalf based on parameters pre-configured by the
advertiser ahead of time. The advertiser buying tool then sends its highest bid for the
impressionas calculated by the tool—back to the ad exchange for consideration.
56. After receiving bids from multiple advertiser buying tools, the ad exchange holds
an auction to determine the winning bidder. Historically, most ad exchanges ran a second-price
auction in which the winning bidder paid a price one cent higher than the bid of the second-
highest bidder. Today, however, most ad exchanges run first-price auctions where the highest
bidder simply pays the price of its winning bid. The ad exchange sends information about its
winning bid back to the publisher ad server, which evaluates the ad exchange’s bid under a set of
rules defined by the publisher ad server. The publisher ad server then makes the final decision
regarding which ad to “serve” to the user. The publisher ad server sends a message to the
winning advertiser to provide the content of the ad to be displayed.
B. How Ad Tech Intermediaries Get Paid
57. Once the winning bid has been chosen, the advertiser pays the website publisher
for the impression, but a portion of the payment is retained by each intermediary along the way
as payment for its services. The advertiser buying tool and the ad exchange supplying the
winning bid each collect a portion of the purchase price for the impression, which is referred to
as a “revenue shareor “take rate.” The publisher ad server generally charges the publisher a
fee based on the number of impressions served. Unlike a revenue share, the publisher ad server
fee typically does not vary based upon the price paid for each particular impression.
22
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 27 of 153 PageID# 27
58. The total percentage of advertiser spend extracted by ad tech intermediaries can
have a substantial impact on the revenue website publishers earn from advertising and on the
return on investment that advertisers receive from their advertising campaigns. But this
percentage is typically not fully transparent to advertisers or publishers; some fees are disclosed
only to publishers or advertisers while other fees are obscured or not disclosed at all. According
to Google’s internal documents, when a transaction passes through each of Google’s ad tech
tools (including Google’s campaign manager product, which helps advertisers manage ad content
and track campaign spending), Google estimates that it gets to keep about 35% of every dollar
spent on digital advertising (as shown in Figure 4 below).
Fig. 4
59. These technology platforms have provided essentially the same services for over a
decade. During that time, Google’s monopoly positions and the restrictions it has imposed across
these technologies have diminished the incentive and ability for Google or others to innovate.
This reduced innovation is compounded by high prices: despite publishers’ and advertisers’
23
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 28 of 153 PageID# 28
interests in reducing the amount of advertising spending siphoned off by intermediaries,
Google’s take rate has remained remarkably stable over time. In particular, Google has
consistently charged a roughly 20% fee for impressions bought through its ad exchange, the link
in the chain where the highest fees are charged.
C. How Publishers and Advertisers Select Ad Tech Tools
60. Publishers and advertisers try to optimize their use of ad tech to meet their
revenue or advertising goals. As a general matter, publishers use only one publisher ad server to
manage ad inventory in order to avoid discrepancies in tracking revenue or impressions and to
minimize the burden of having employees oversee two largely duplicative systems. Ultimately,
there can only be one publisher ad server acting as the final decision-maker as to which
advertisement will fill each impression.
61. Sizeable publishers generally prefer to offer their inventory for sale through more
than one ad exchange (a practice called “multi-homing”). This increases the likelihood that an
advertiser on one or more of the ad exchanges will be able to “match” the advertising
opportunity offered by the publisher to a user or category of user that an advertiser particularly
values and therefore is willing to compete to buy. When publishers are able to offer their
inventory for sale through multiple ad exchanges simultaneously, it causes ad exchanges to
compete with each other to provide the best “match” or the lowest revenue share. However, there
are integration, contracting, and other costs associated with the publisher adding each additional
ad exchange.
62. Likewise, advertisers often connect with multiple ad exchanges through their
advertiser buying tools, hoping that exposure to as much advertising inventory as possible will
increase the likelihood of reaching the advertisers’ intended targets for their advertising
campaigns at the lowest cost. Using multiple ad exchanges also allows advertisers to compare
24
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 29 of 153 PageID# 29
performance between ad exchanges. Similarly, when advertisers are able to freely multi-home
among ad exchanges, it forces ad exchanges to compete with each other to provide advertisers
the best return on their advertising expenditures.
63. Although there are a number of factors that advertisers consider when deciding
which ad exchanges and/or ad buying tools to use, one key driver is access to especially valuable
advertising inventory. Some ad tech products can be used to buy or sell both open web display
advertising—the focus of this Complaint—as well as other types of advertising, such as
advertising inventory that is “owned-and-operated” (“O&O”) by the company offering the ad
tech product.
64. For example, some of Google’s ad tech products allow advertisers to buy both
open web display advertising on third-party websites as well as advertising on Google’s O&O
properties. Google’s O&O properties include several market-leading sources of non-open web
display advertising inventory, such as Google Search, YouTube, Gmail, and Android’s Google
Play Store, among others. Advertisers and advertising agencies looking to advertise on these
O&O properties often must adopt at least one of Google’s advertising tools to do so effectively.
For example, many larger advertisers and ad agencies seeking to promote their brands through
online video advertising on the market-leading YouTube website generally must use Google’s
advertising tools to do so; so for them, as well, adoption of Google’s ad tech tools is considered a
must.
65. If an advertiser or advertising agency believes it needs Google’s tools for
purposes of Google O&O advertising, it is less likely to adopt another buying tool—or tools—to
advertise on the open web. Among other considerations, the adoption of multiple ad tech tools
typically costs more (in time and money) and limits the ability of the ad tech tools to share
25
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 30 of 153 PageID# 30
important performance data across these tools. As a result, companies with especially valuable
O&O advertising—such as Google—may be able to take advantage of existing, sizeable
advertising bases already locked into their advertising tools.
D. Why Scale and the Resulting Network Effects are Necessary to Compete in Ad
Tech
66. Scale is a critical factor in the long-term success of each of the key products that
comprise the ad tech stack. Scale and related network effects are cumulative; they reinforce
market power for incumbents and raise barriers to entry and competition for nascent and smaller
rivals. There are at least three important dimensions of scale at play in online digital display
advertising.
67. First, scale in ad tech means having a significant number and variety of publishers
or advertisers using a particular ad tech product. For example, an ad exchange that has
significant scale enjoys large numbers and varied types of (i) publisher advertising inventory, on
the one hand; and (ii) advertisers that bid through the ad exchange, on the other hand. This scale
is key to attracting both publishers and advertisers to the ad exchange because ad exchanges are
characterized by strong network effects (meaning that the value of an ad exchange to its users
increases as more users adopt the tool). An ad exchange with access to more inventory—
especially more sought-after inventorywill be more attractive to advertisers. Likewise, an ad
exchange with more advertisers—and more unique advertisers—will be more attractive to
publishers. This aspect of scale plays out in similar but less pronounced ways for publisher ad
servers. For example, larger and more valuable inventory justify an ad exchange incurring the
cost to integrate with a particular ad server. Publisher ad servers are also relatively more
expensive to build and relatively less expensive to run, so a larger publisher base allows the
publisher ad server to spread the fixed costs over more publishers. With respect to advertising
26
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 31 of 153 PageID# 31
buying tools, more advertisers and more overall advertising spend will attract publishers to a
particular tool. Moreover, to the extent that an advertiser buying tool has access to data from a
related sell-side product, the advertiser buying tool can gain unique targeting abilities.
68. Second, scale includes the number and quality of impressions that publishers have
offered for bidding through the ad tech product, the number of bids advertisers have made, and
the number of transactions that have been completed—as well as the associated revenue for those
transactions. The more business the ad tech provider has done, the more data that provider has,
and the greater the ability the provider has to increase the value of its services. For example, an
ad tech provider that is able to see a larger swath of advertising inventory made available for
auction will have greater insights into the universe of inventory available, and can adjust—or
suggest adjustments to—its customer’s bidding behavior accordingly. Additionally, an ad tech
provider that is able to see at scale who ultimately buys or bids on inventory and at what prices
can create bidding strategies that can be used to predict more accurately future auctions for
similar inventory. For example, the ability to observe the depth and distribution of bids for
different advertising inventory can provide valuable data on how demand might change based on
price and other factors. In addition, data concerning advertisers’ buying strategies, and how all of
this information changes over time, is incredibly useful. Without access to this type of inventory,
bidding, and transaction information at scale, an ad tech provider is less able to offer a
competitive ad tech tool to publishers or advertisers.
69. Third, scale includes the depth of targeting data that an ad tech product has
available and can use to identify the most valuable matches between particular pieces of
publisher inventory and advertisers. This aspect of scale in the ad tech ecosystem is influenced
both by an ad tech provider’s access to relevant targeting data from seeing and winning more
27
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 32 of 153 PageID# 32
digital advertising transactions (which can provide important information on an internet user’s
characteristics and behavior) as well as from other parts of its business (e.g., Google’s access to
website contextual data and detailed user profiles on its customers using Search, Chrome,
Android, or Gmail).
70. The ability of an ad tech product to achieve scale along these dimensions is
important to its long-term success. For an ad exchange, increasing publisher inventory and
advertiser demand, understanding the likely bid landscape based on prior consummated
transactions, and having access to detailed user targeting and contextual data all increase the ad
exchange’s chances of being the supplier of the advertiser bid ultimately selected by the
publisher ad server. This is key because ad exchanges only collect a revenue share on winning
bids—even though the ad exchange incurs costs (for personnel, equipment, and processing
power) for every bid request and response, whether won or lost. An ad exchange lacking
sufficient access to these various dimensions of scale may not be able to compete effectively,
innovate, or even operate.
E. How Multi-Homing Enables Competition in the Ad Tech Stack
71. The purpose of the ad tech stack is to bring together publishers and advertisers.
Publishers benefit when there are more advertisers to bid on their inventory, and advertisers
benefit when there are more impressions available to buy. As a result, the various markets that
make up the ad tech stack exhibit strong “indirect network effects,” i.e., the value of the services
provided by these ad tech tools increases as the number of participants on both sides of the
product increases.
72. Additionally, because each possible advertising opportunity (or impression) is
unique based on a variety of factors (e.g., the identity of the user, the substance of the website,
the location on the webpage), the value of a particular impression opportunity can vary
28
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 33 of 153 PageID# 33
significantly across advertisers. For example, a banner ad at the top of an automotive website
would be highly valuable to a car dealership located in the same zip code as the user; that same
banner ad space would be less valuable to a home improvement store located in another state.
Digital advertising technology, when operating in a healthy, competitive environment, attempts
to create the most value for its customers by matching publisher advertising opportunities with
the advertisers willing to pay the most for them. By multi-homing across ad exchanges, both
website publishers and advertisers are able not only to seek the best possible match for a given
advertising opportunity, they are also able to contribute to, and benefit from, competition more
generally.
73. Ad exchanges compete for publisher inventory and advertiser demand at two
distinct but related levels. First, they compete for adoption by publishers and advertisers, i.e., the
opportunity to see a publisher’s inventory or submit an advertiser’s bid. Second, once an
exchange has been adopted, it competes with other exchanges to win the ability to process a
particular advertising transaction (i.e., to win individual advertising auctions). At both levels of
competition, ad exchanges compete not only on price but also on quality and access. Generally,
an ad exchange with more advertisers will be more valuable to publishers, and vice versa. When
both sides in a market single-home (i.e., only connect with a single ad exchange), sellers
(publishers) tend to flock to the ad exchange with the most buyers (advertisers), all else being
equal. Advertisers likewise prefer the ad exchange that has the most advertising inventory from
publishers. Google’s dominance of scale on both sides of the ad tech stack thereby strengthens
Google’s dominance overall in the industry and weakens its rivals’ ability to compete.
Conversely, when participants on both sides actively multi-home, there may be multiple
exchanges that offer access to the other side of the market, applying competitive pressure to
29
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 34 of 153 PageID# 34
decrease fees or increase quality in order to win business. Thus, actions that impair the ability of
one or both sides to multi-home are invariably corrosive to competition.
IV. GOOGLE’S SCHEME TO DOMINATE THE AD TECH STACK
74. Over the past fifteen years, Google has acquired and maintained mutually
reinforcing monopoly positions in tools across the ad tech stack. Google’s scheme has involved a
range of conduct, whereby it—often surreptitiously—has wielded its market power in various ad
tech tools to undermine attempts by publishers, advertisers, and rivals to introduce more
competition for digital advertising transactions. Individually and in the aggregate, Google’s
anticompetitive acts have deprived rivals of critical scale and contributed to Google’s dominance
by erecting substantial barriers to entry and competition.
75. Google also has used its dominant position time and again to prevent publishers—
its own customersfrom efficiently and effectively multi-homing across ad exchanges, and to
prevent rival ad tech providers from deploying technology that would have improved the process
by which advertisers and publishers find the best advertising matches in real time for each
impression. In the face of potential competitive threats, Google has resisted innovation and
chosen not to compete on the merits. Instead, it has used acquisitions and market power across
adjacent ad tech markets to quash the rise of rivals, tighten its control over the manner and means
through which digital advertising transactions occur, and prevent publishers and advertisers from
30
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 35 of 153 PageID# 35
working effectively with Google’s rivals. As the figure below demonstrates, Google’s
dominance across the ad tech industry is unparalleled.
Fig. 5
A. Google Buys Control of the Key Tools that Link Publishers and Advertisers
76. Google entered display advertising on the back of its early strength in search and
search advertising. In 2000, Google launched Google Ads (then called “AdWords”), a self-
service buying tool for advertisers. At the time, advertisers could use Google Ads to purchase
advertising on the webpage displaying Google search results.
77. As Google’s search engine dominance grew, it attracted large numbers of small
and large businesses that considered advertising on Google’s search results page to be critical to
reaching customers searching for their products or services. After amassing this pool of
advertisers, Google realized it could not only sell them advertising space on Google’s search
results page, but also step in as an intermediary to sell them advertising space on non-Google
websites as well. Thus in 2003, Google changed the default setting on Google Ads so that
businesses were automatically opted into using Google Ads to advertise on third-party websites
31
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 36 of 153 PageID# 36
through what became known as Google Display Network, or “GDN.” Today, Google Ads has
grown to represent over two million advertisers, spending about $11 billion worldwide on open
web display inventory per year. Google Ads is a substantial, unique source of advertising
demand and revenue for publishers.
78. In 2006, Google found itself without sufficient access to non-Google premium
advertising inventory to meet its advertisers’ demand. Effectively integrating Google Ads with
existing publisher-facing platforms would have benefited both Google Ads advertisers—by
increasing their access to inventory—and Google—by increasing advertising sales, and in turn
Google’s total revenues as a percentage of those sales. Instead, Google sought to maintain more
control over advertising purchases made by its Google Ads’ advertisers. In particular, it limited
the ability of its Google Adsadvertisers to buy inventory from Google’s rivals. Google
recognized that if it could secure access to its own pool of publisher inventory, it could control
the entire transaction, end-to-end, and become the “the be-all, and end-all location for all ad
serving.To that end, Google built and launched its own publisher ad server, but the product
failed to gain traction.
79. Rather than innovate and compete, Google found a shortcut. In 2007, Google
announced that it would buy DoubleClick for $3.1 billion. DoubleClick offered the industry-
leading publisher ad server, called DoubleClick for Publishers or “DFP”, which at the time had
an estimated 60% market share. DoubleClick also was developing a nascent ad exchange, called
AdX.
80. The DoubleClick acquisition was a pivotal moment for Google’s display
advertising technology business and its strategy to dominate the ad tech stack. The deal provided
Google with direct access to website publishers (and their inventory) on DoubleClick’s publisher
32
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 37 of 153 PageID# 37
ad server and, for the first time, a significant presence on both the advertiser and publisher sides
of the ad tech stack. Google feared that if a rival acquired DoubleClick, Google would not
control all the tools that link Google’s advertisers with publisher inventory; in short, a rival could
“disintermediate” Google. Disintermediation risked allowing another company to control how
and where publishers sell impressions to advertisers, something Google would not tolerate
because it would limit Google’s ability to generate monopoly profits. Setting the stage for what
was to come, the DoubleClick acquisition provided Google the unilateral power to implement a
series of anticompetitive restraints, using its dominance on both the publisher and advertiser
sides of the market to inhibit competition across the entire ad tech stack.
81. The Federal Trade Commission (“FTC”) investigated Google’s proposed
acquisition of DoubleClick. The FTC considered “the possibility that Google could leverage
DoubleClick’s leading position in third party ad serving to its advantage in the ad intermediation
market” and whether Google could “exclusively bundle AdWords [advertiser demand] with [its
publisher-side platforms] AdSense and DFP.”
82. The FTC ultimately declined to challenge Google’s acquisition of DoubleClick
for the reasons set out in its public closing statement. The FTC concluded that “DoubleClick
does not have market power despite its high market share”—over 60% at the time—and that
“firms can and do switch ad serving firms when it is in their self-interest to do so.” Based on
these assumptions, the FTC believed any anticompetitive conduct by Google “would likely be
defeated by customers switching to one of the other third-party ad serving products.”
83. Google’s contemporaneous business documents paint a very different picture,
however. Six months after the FTC closed its investigation without taking action, one senior
Google executive wrote about the importance of controlling access to publisher inventory
33
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 38 of 153 PageID# 38
through the DFP publisher ad server, stating “the thing we want ‘secured’ is the DFP platform
adoption” because “if we have this” then Google would “have a +20% monetization advantage.”
In other words, Google believed it could sustainably charge a higher price on advertising
transactions than its competitors because it controlled the process and rules by which publisher
inventory could be sold.
84. Google knew the emerging ad tech market better, and acknowledged in internal
documents that “due to [the publisher ad server’s] position as the operating system for ad sales,
switching costs are very high.” Because of this “stickiness” of publisher ad servers, Google knew
it could manipulate the system in its favor—and to the detriment of competition—without fear
that publishers would switch to other publisher ad servers. After the acquisition was completed,
the former DoubleClick CEO explained at an internal Google strategy meeting, “My view is
nothing really matters but the platform [publisher ad server]. Nothing has such high switching
costs. If there’s a better network or exchange, you can just switch to it. Switching platforms is a
nightmare. Takes an act of God to do it.”
85. Following the DoubleClick purchase, Google cemented its position as the
dominant intermediary between advertisers and publishers through a series of additional
acquisitions that eliminated potential competitors and further bolstered Google’s position in open
digital advertising. For example, in 2009, Google paid $750 million to purchase AdMob, a
technology system that allowed publishers of mobile apps to sell ads as well. While Google’s
conduct in the distinct market for mobile app advertising is outside the scope of this Complaint,
Google’s anticompetitive conduct in the mobile apps market is consistent with the conduct
alleged in the market for display advertising.
34
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 39 of 153 PageID# 39
86. In 2010, Google acquired Invite Media for approximately $81 million. Invite
Media offered a demand side platform. Google subsumed Invite Media into a demand side
platform it was developing, Display & Video 360 (at the time, known as “DoubleClick Bid
Manager). By capturing an increasingly large share of bigger, more sophisticated advertisers
and advertising agencies, Display & Video 360 complemented Google Ads and expanded
Google’s control over advertiser demand.
87. In 2011, Google bought AdMeld for approximately $400 million. As discussed
further below, AdMeld had developed technology to provide “yield management” functionality
to publishers. Yield managers like AdMeld helped publishers manage inventory and optimize
revenue by comparing offers from multiple advertiser demand sources at the same time. This
comparison feature made it easier for new ad exchanges and advertiser demand sources to enter
the ad tech industry because it gave publishers the incentive and ability to switch between ad
exchanges and advertiser demand sources in response to better prices and service.
88. The DoubleClick, Invite Media, and AdMeld acquisitions helped Google achieve
dominant positions at each level of the open web ad tech stack and set the stage for Google to
control and manipulate the process by which publishers sell and advertisers buy open web
display inventory.
B. Google Uses Its Acquisitions and Position Across the Ad Tech Stack to Lock Out
Rivals and Control Each Key Ad Tech Tool
89. After amassing a position as the dominant intermediary for display advertising,
Google used its monopoly power over each level of the ad tech stack to reinforce its dominant
positions and limit where and how other ad tech providers could compete. Most notably, Google
made its Google Ads’ demand available only through its AdX ad exchange. In turn, Google
effectively made its ad exchange available only to publishers using its publisher ad server (DFP).
35
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 40 of 153 PageID# 40
This benefited Google’s long-run aspirations of dominating the publisher ad server market, at the
expense of Google Adsadvertisers seeking access to the widest variety of publisher inventory at
the lowest price. By allowing only its own publisher ad server effective access to important,
unique Google Ads’ demand, Google could force publishers to adopt and remain on its publisher
ad server; other ad servers could not compete to offer a similar product. But this restriction
meant Google Adsadvertisers could not buy inventory available only on other ad exchanges or
via non-Google publisher ad servers, and they could not take advantage of fee competition that
might make that advertising inventory less expensive. The restriction also was contrary to
Google’s short-term financial interests, which turned on buying more and more-valuable
advertisements from as many publishers as possible.
90. Google introduced several policies and auction changes to force more transactions
to flow through its platforms and make it more difficult for publishers to switch ad servers.
These restrictions collectively stifled competition by artificially preventing rivals from
competing on the same terms as Google’s products, thereby impeding publishers’ and
advertisers’ ability to work effectively with rivals and allowing those rivals to obtain scale.
Google implemented these restrictions even though it knew that it would have been better for
Google Adsadvertisers (and far more profitable for Google Ads in the short run) to multi-home
across ad exchanges. And, likewise, publishers would have benefited from being able to
effectively access advertiser demand through multiple ad exchange intermediaries. These
restrictions had the effect of taking Google’s publisher ad server from a market leader to a
monopoly—currently with no credible competitionand catapulting its nascent ad exchange
into a monopoly position that dwarfs all other ad exchanges.
36
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 41 of 153 PageID# 41
1. Google Thwarts Fair Competition by Making Its Google Ads’ Advertiser
Demand Exclusive to Its Own Ad Exchange, AdX
91. The DoubleClick acquisition was a first step in Google’s march to monopoly.
After purchasing DoubleClick, Google restricted Google Ads’ purchasing of display inventory to
sources controlled by Google (inventory owned by Google or by publishers using Google’s
monetization products, including its newly acquired publisher ad server). The goal was
ultimately to lock publishers into its ad exchange and publisher ad server, and block competing
ad exchanges and publisher ad servers from accessing Google’s valuable pool of advertiser
demand. Google implemented this restriction when it launched “AdX 2.0” on September 17,
2009. At the time, Google identified one of AdX’s two differentiators from other ad exchanges
as unique “access to AdWords advertisers.”
92. Google has continued to sacrifice profits and act against the interests of its own
advertisers by blocking its Google Adscustomers from buying almost any inventory through
non-Google platforms, such as rival ad exchanges and networks, even if those competitors
offered more valuable inventory or the same inventory at lower prices. Google estimated that by
2017, Google Ads was forgoing $863 million per year in revenue by not purchasing inventory
from rival ad exchanges and networks. But Google believed this forgone revenue was worth it in
the name of advancing its growing moat and protecting its monopoly positions across the ad tech
stack. Exclusive access to Google Ads’ demand compelled most publishers to adopt whichever
ad tech tools Google required to effectively access that demand.
37
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 42 of 153 PageID# 42

93. Google Ads’ unique and sizeable advertiser demand is what makes Google’s ad
exchange unavoidable for most website publishers. Google Ads’ demand is unique both in its
volume and diversity of advertisers (now with more than two million) and in its ability to attract
advertisers at scale who cannot effectively use any other digital display advertising tool to
purchase ads on the open web. Even for Google Ads’ advertisers who can use alternative buying
tools, many of them are pushed into Google Ads in order to buy other forms of critical
advertising inventory that Google makes available effectively only through its buying tools, such
as portions of YouTube, Gmail, and Search ad inventory. Together, these characteristics mean
that Google Ads has a significant scale advantage by controlling a unique demand group (that
spends about $11.5 billion on display inventory each year).
94. Google Ads is also differentiated from other sources of advertising demand
because Google’s data-targeting advantages allow it to identify inventory that is uniquely
9
Diagrams are provided throughout to highlight the location within the ad tech stack where the
conduct predominantly occurred. They are not intended to identify all areas where the identified
conduct impacted the competitive process or other market participants.
38
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 43 of 153 PageID# 43
valuable to Google Ads’ advertisers. Google Ads’ targeting data is derived from a wide array of
user data that Google compiles across its many market-leading or monopoly products (e.g.,
Chrome, Gmail, Google Search) as well as data that Google requires its publishers to share with
it through a data pool called the “ICM Coop.”
10
Google Ads combines this targeting data with
contextual data Google extracts while crawling publisher websites. These sources of data fuel the
immense network effects that raise barriers to entry and insulate Google from competitive
pressure.
95. The advertiser make-up and data advantages of Google Ads lead it to buy large
swaths of inventory that otherwise would go unsold. Certain inventory is valuable only to
advertisers that use Google Ads exclusively; other inventory is undervalued without the user
targeting and contextual data that Google makes available only to Google Ads. Google does not
simply limit access to this data to its own advertiser buying tools. It also has exercised its market
power to undercut rivals’ ability to compete using the same or similar data. For example, after
the DoubleClick acquisition, Google “hashed” (i.e., masked) the user identifiers that publishers
previously were able to share with other ad technology providers to improve internet user
identification and tracking, impeding their ability to identify the best matches between
advertisers and publisher inventory in the same way that Google Ads can. Of course, any
purported concern about user privacy was purely pretextual; Google was more than happy to
exploit its users’ privacy when it furthered its own economic interests.
11
10
The ICM Coop is not a real cooperative among website publishers. Rather, it is a data pool
over which Google has sole control that publishers must participate in in order to receive
competitive bids from Google Ads. Google estimated the value of this data to Google Ads was
$4 billion in 2015.
11
See supra, n. 3.
39
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 44 of 153 PageID# 44
96.
Google
recognized the power it wielded in Google Ads and used
it to prop up and
insulate its other ad tech products from competition. According to a 2011 internal analysis,
Google
found that allowing Google
Ads to buy inventory on rival ad
exchanges
would cause
serious losses to its publisher platforms
(DFP and AdX)
because many publishers and advertisers
would prefer to transact through rival
platforms. Google
estimated
that in such a scenario
its ad
exchange would lose 20 t
o 30% of its impressions, and its
publisher
ad server would lose 20% of
its publishers. Later internal studies confirmed Google Ads’ stranglehold. A 2014 Google
experiment found that more than half of the
impressions that publishers offered on its ad
exchange would go unsold without the critical Google Ads’
demand. If
the Google Ads
demand
was removed from the ad exchange, Google’s publishers would experience
a 65% drop in
revenue because no advertisers outside of Google
Ads were interested in buying the unique
impressions available or
able to do so in light of the auction restrictions described below. Google
congratulated itself on having effectively locked out meaningful
competition. At one Google
strategy meeting, Google executives applauded the fact the “unique Google Display
Ad demand
allowed it to justify “why we can charge 20%” fees for open auction transactions won on AdX,
even on transactions that did not use Google
Ads’
buying tools.
97.
By preventing publishers from accessing this
incredibly valuable
demand through
rival ad exchanges that publishers otherwise would prefer, Google distorted the way in which
website publishers
partner with Google’s competitors. As Google’s former
head of
global
strategy and commercialization explained: “When
[advertiser]
demand can only be found
through certain sources, it compels
publishers to work with that product.”
Because Google owns
both DFP and Google Ads, a
nd publishers needed to use DFP to access Google Ads’
demand
40
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 45 of 153 PageID# 45
effectively,
Google had no incentive to operate DFP for its own publisher customers’ benefit in
the way that DoubleClick did.
98.
For
Google
Ads’ single-homing advertisers, Google has made it impossible for
any rival ad exchanges
to
compete for the opportunity to link them
with publisher inventory. As
a result of this restraint, single-homing advertisers
have more limited access to advertising
inventory (less
“reach”). Google recognizes
that while
this exclusivity
locks in publishers, it
harms Google Ads’
advertisers, which have no reasonable alternatives to which they can turn. As
explained in one 2012 internal document, t
he policy
amounts to a
“buyside-subsidizes-sellside
model” that “artificially
handicap[s] our buyside (GDN
[Google Ads]) to boost the attractiveness
of our sellside (AdX
[ad exchange]).”
Later, in 2014, one Google employee complained about
Google Ads
sending Google’s publisher platforms
a “$3bn yearly check by
overcharging our
advertisers to ensure we’re strong on the pub[lisher] side.” These complaints by
Google’s own
employees working on Google’s
advertiser tools reflect the
artificiality of the restrictions
imposed on Google
Ads, and make clear that
the restrictions
are what they
seem:
blatant
exclusionary conduct
designed to obtain a
nd maintain monopoly power
rather than efforts to
build a viable, vibrant
ad
exchange.
Deliberately overcharging its own advertisers is also clear
evidence of monopoly power over the advertising s
ide of the ad tech industry. No other
competitor could engage
in such conduct and expect to stay in business.
99.
In response to pressure
from within Google’s own ranks, including by
employees
managing G
oogle Ads, and only after it shored up its market position across the ad tech stack,
beginning in 2015, Google allowed limited categories of advertising demand to bid for some
inventory on rival ad exchanges. This was something that Googles
engineering team had
previously
considered and viewed as technically possible, but which its product leadership had
41
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 46 of 153 PageID# 46
refused to allow. Google’s buy-side employees championed this new feature as in the interest of
Google Ads
advertisers
and Google Ads itself, as a standalone product.
100.
Even for the limited subset of demand that Google finally allowed Google
Ads to
bid on rival ad exchanges, Google disadvantaged those bids.
Specifically,
Google
refused to
allow Google Ads’ advertisers
to submit bids to rival exchanges using
the same bid modelling
and targeting data that Google Ads used to generate bids for Google’s own
ad exchange.
Likewise, when submitting Google
Ads’ advertisers’ bids to rival exchanges, Google submitted
only the single highest bid, whereas when Google
submitted
the same advertisers’ bids to
Google’s own ad exchange, AdX, Google submitted
its two highest bids to improve the revenue
payout to publishers.
101.
In effect,
Google systematically decreased the payout that Google Ads provided
to publishers by extracting higher
fees on the transactions (now ranging f
rom 32% to 50%). In
aggregate, Google understood “32% margin and no 2
nd
price makes [Google Ads demand] less
desirable to access via a middle-man.” Once again, Google acted to preserve its own monopoly
power rather than its customers’ best interests.
102. Google implemented these changes not because it was interested in helping its
advertisers achieve the best return on their advertising investment; rather, by submitting two
bids, G oogle was able to redirect sales back to AdX, ensuring AdX’s “must have” status in the
industry and making it difficult for rivals to have the scale necessary to compete. In fact, Google
has gone so far as to enter into non-disclosure agreements with these rival ad exchanges to
prohibit them from telling publishers that even this limited form of Google Ads demand could
be found out side of Google’s ad exchange. Google imposed these restrictions because it
understood that “when our competition is able to say that they have access to [Google Ads],
42
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 47 of 153 PageID# 47
whether it is equal or not, our sales and marketing t
eams will have to be prepared for significant
competitive pressure.” Rather than face that competitive pressure,
Google
simply restricted rival
exchanges
ability to market their capabilities to their publisher customers.
103.
Google’s
coupling of
Google Ads
demand to its
budding
ad
exchange was
significant in
Google’s
plan to dominate the market and exclude competition. Google took its
existing scale advantages in Google Ads
and extended those to Google’s other ad tech products,
by driving more opportunities and transactions through them
and away from rival marketplaces.
As predicted, Google’s nascent
ad
exchange grew exponentially
after its relaunch in 2009. In the
wake of the
DoubleClick acquisition and the implementation of these restrictive policies,
Google’s ad exchange display revenue
grew 283% in 2009 and an astounding 844% in 2010. By
June 2011, Google executives boasted about becoming the
“#1 player”
in U.S. display
advertising, a substantial
jump for a company that
had failed to gain traction with
its own
publisher
ad server just
five years earlier. T
oday, because
of this exclusionary
conduct, 95% of
Google
Ads’ spend flows through Google’s own AdX ad exchange, while less than 5% flows
through rival ad exchanges. The combination of Google’s
acquisitions
with its anticompetitive
business practices
has
suppressed,
or altogether
eliminated,
the necessary
growth
for
rivals to
compete.
2.
In Turn, Google Makes
Its Ad Exchange’s Real-Time Bids Exclusive to
Its Publisher Ad Server
104.
At the same time, Google used
what most publishers saw
as
AdX’s
must-have
status to reinforce
and grow its
already dominant
publisher ad server, DFP, ultimately pushing
remaining publishers to adopt Google’s ad server
and forcing rivals to exit
the market. With its
relaunch of the ad
exchange after the DoubleClick acquisition, Google
required publishers to use
its ad server to obtain real-time bids from its
ad
exchange.
If a publisher
chose not to use DFP, it
43
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 48 of 153 PageID# 48
was relegated to selling impressions to AdX at a floor price based on historical average prices,
which were often much less than the real-time, impression-specific bids AdX made through
DFP. As a 2018 Google presentation bluntly noted, “[DFP] is the only way to access [AdX] as a
publisher.”
Fig. 7
105. Google did not need to make AdX exclusive to DFP in this way, but nevertheless
decided to pursue the most restrictive alternative. In 2011 and 2012, Google developed a feature
that would enable AdX to compete for inventory in the same way on other publisher ad servers.
The feature was available in beta to some partners and required only “minimal effort” to roll out
commercially. But Google saw that this feature risked taking away a “key differentiator for
DFP”: access to real-time AdX demand. As one Google employee explained in September 2012,
“it is too early to give AdX to non-XFP [DFP] partners. . . . This is an amazing time to ‘lock in’
impressions by offering XFP [DFP] to publishers . . . . AdX can serve as a tool to pull publishers
onto XFP [DFP]. . . . Ad Servers are sticky, and hard to replace. The next 12 months are a very
good time to switch publishers over.” By 2013, Google decided to end this experiment in
44
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 49 of 153 PageID# 49
openness, with Google’s
lead product manager
for AdX declaring:
[O]ur goal should be all or
nothing
– us
e AdX
as
your SSP or don’t get access to our demand.”
106.
By limiting Google Ads’
demand to the AdX ad exchange, and limiting real-time
access to the ad exchange to publishers using Google’s publisher ad server, Google
compelled
publishers to adopt its ad server
for effective access to Google Ads’
demand.
Recognizing the
importance of real-time competition for ad inventory—which
priced an advertisement based on
the particular
characteristics of a webpage user at that specific point in time—Google blocked
publishers using rival ad servers
from connecting to
Google’s ad exchange in the same way.
Google knew that its Google Ads’ advertisers provided a unique, rich source
of advertiser
demand, and that no other publisher ad server
(or
ad exchange)
could offer
similar access to such
a lucrative pool
of advertiser demand. Many publishers could not afford to use a rival publisher
ad server because they
could not afford to lose the
revenue that Google’s exclusively-linked
platforms could provide. In essence, Google dictated publishers’ choice of
each key ad tech tool
used to sell their inventory: publishers must make
their inventory available
through Google’s
publisher ad server and ad exchange to get the opportunity to sell a portion of it to Google’s
extremely valuable Google Ads’ advertisers.
107.
By 2015, these
restrictions had virtually
eliminated competition between
publisher ad servers, driving rivals to abandon the
market completely. Google’s market share for
publisher ad servers soared from 60% in 2008 to 90%
by 2015. In a 2016 customer presentation,
Google described DFP as the “defacto
[sic]” publisher
ad server
with a “90% market share.”
At
the same time, it guaranteed to Google Ads—via
Google’s ad exchange—preferential access to
an unrivaled swath of publisher inventory, as well as the associated contextual and user targeting
data, which supported
Google Ads’
remaining a dominant, scaled
ad network.
45
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 50 of 153 PageID# 50
108. To this day, Google’s restrictions and conduct essentially foreclose the possibility
of entry into the publisher ad server market. To enter the publisher ad server market, a
competitor not only would need to offer a full-featured ad server, but also would need to be able
to link it to an ad exchange and advertiser demand source of the same size and scale as Google’s
ad exchange and Google Ads’ advertiser demand. Without such a full-stack offering, a
competitor would need to convince publishers to sacrifice effective access both to Google’s ad
exchange as well as access to Google Ads’ unique advertiser demand, an ask that is simply not
economically feasible given Google’s successful exclusionary conduct to date.
3. Finally, Google Uses Its Control of Publisher Inventory to Force More
Valuable Transactions Through Its Ad Exchange
109. Google’s ownership of the leading publisher ad server, DFP, allowed it to set the
rules that governed how most publisher inventory in the market is sold. Google internally
referred to publisher ad servers as the “ad revenue operating system for publishers” because they
decide who is offered a chance to buy publisher inventory and on what terms. Not content to
operate in a free and competitive market, Google altered its publisher ad server rules to force
more transactions—and more high-value transactions—through its ad exchange and advertiser
platforms. The changes did not allow Google’s ad exchange rivals to compete in the same way or
46
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 51 of 153 PageID# 51
on the same terms, largely leaving them with the leftover scraps of inventory that Google’s
advertisers did not want, even at artificially discounted prices.
Fig. 8
110. Until at least the advent of header bidding between 2012 a nd 2013 (and for many
publishers not until at least 2018), publ ishers that wanted to offer inventory to multiple ad
exchanges via Google’s publisher ad server had to use a system known as the “waterfall.” Even
though this system plays a smaller role now than it once did,
12
it played a pivotal role in
establishing Google’s dominance in the ad exchange market, was a critical predicate to certain
other Google conduct, and helped to create the market monopoly that Google enjoys today.
111. Under the waterfall process, t he publisher ad server would send offers to sell
advertising inventory to ad exchanges and advertiser ad networks one at a time in sequence until
it found an eligible buyer. To set up the waterfall, publishers had to manually enter into the
publisher ad server the average price they expected to be paid by each ad exchange based on
12
Because of the difficulties and costs of utilizing newer alternative systems in Google’s ad
server, many publishers are still forced to use the waterfall system today.
47
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 52 of 153 PageID# 52
historical averages. Because these were average prices, they did not necessarily reflect what an
ad exchange would pay for any individual impression at any particular time. The publisher ad
server then ranked each ad exchange from highest to lowest based on average historical price.
Then when a user opened a publisher’s webpage and an ad impression became available for sale,
the ad server offered the impression to the ad exchange ranked highest in the waterfall. If that ad
exchange had an advertiser willing to pay more for the impression than the minimum price set by
the publisher (the “price floor”)—which could differ from the average prices of that ad
exchange—the ad exchange won the impression, and its advertiser was able to display the ad.
The ad was not submitted to any of the other ad exchanges in the waterfall, even if one of them
might have been willing to pay more for the impression. Alternatively, if the first ad exchange
did not have an advertiser willing to pay at least the publisher’s price floor, the ad server called
the next ad exchange in the list. This process continued until someone purchased the impression
or the last ad exchange in the waterfall was called.
48

Fig. 9
112. The inefficiencies associated with the waterfall system are obvious: ad exchanges
at the bottom of the waterfall might never get a chance to bid, even if they could supply a
lucrative bid. In those instances, publishers received less revenue than they could have. But
while this inefficiency plagued how inventory was sold to rival ad exchanges, Google used its
control over the process to allow its ad exchange—and only its ad exchange—to compete outside
of the waterfall process.
113. As part of its post-acquisition relaunch of AdX, on a “system written from
scratch” on Google’s platform, Google redeployed “dynamic allocation.” Dynamic allocation
provided AdX a prized position over all other indirect sources of advertising demand, which
allowed AdX to both “see more” and “win more” valuable publisher inventory.
114. First, Google configured its publisher ad server to afford Google’s ad exchange a
“first look” at all inventory the ad exchange was eligible to buy. Google’s publisher ad server
49
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 54 of 153 PageID# 54
always called
Google’s ad exchange for
a real-time bid before offering inventory to rival
ad
exchanges. This placed
Google’s ad exchange at
the top of every
waterfall, regardless of where it
would otherwise be
ranked based on its average historical prices. In practice, it meant that
Google’s ad exchange saw more publisher inventory
than any other
ad exchange and could offer
advertisers the
ability
to obtain the most valuable impressions by simply paying slightly
more
than a static historical average
price paid by rival
ad exchanges.
115.
Second, before Google’s
ad exchange competed for an
impression, Google’s
publisher ad server shared with its ad exchange the highest competing price from the waterfall,
i.e.,
the highest average
price of
a rival ad exchange. This set the auction floor price within
Google’s ad exchange and provided bidders
on Google’s
ad exchange
with two key advantages:
(1) buyers on Google’s ad exchange could see the floor price
(i.e.,
the minimum price to win)
and adjust their bids accordingly;
and (2) buyers on Google’s ad exchange
often had to pay only
that average
price of the rival ad exchange. The latter of these advantages
was a function of
Google
conducting a second-price
auction on its ad exchange. Under this auction format, if only
one bid on Google’s ad exchange was higher than the price floor, that bid won the inventory at
the floor price that had been set by the rival ad exchange’s
average price.
In this way, Google’s
ad exchange was able to
win high-value impressions without paying the price advertisers on
other ad exchanges
were actually willing to pay.
116.
Third, G
oogle configured the ad server to allow its ad exchange to compete on the
basis of real-time pricing derived from its internal auction for a particular impression shown to a
particular internet user.
Unlike rival ad exchanges, Google’s ad exchange was not relegated to
competing on the basis of historical average prices. Combined with Google’s treasure trove of
user targeting and webpage
contextual data, Google’s control over the ad server
allowed it to
50
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 55 of 153 PageID# 55
tailor its bids more carefully; that is, it could bid
high for
a more valuable
impression and low for
a less valuable impression. For example, it could offer
a publisher $10 CPM to show a car
dealer’s advertisement to a user who
recently
clicked through several car
manufacturer websites
while offering the same publisher only $1 CPM to show the same ad to a 14-year-old user who
resides in a state where the dealer does not operate. Google’s publisher
ad server
would not
permit other ad exchanges to compete in this way. Instead, all other
ad exchanges were forced to
compete on the basis of the “waterfall” method using historical, average prices, even though the
industry quickly developed a technology standard to bid in real time in this
way.
117.
This two-tiered arrangement denied rival ad exchanges the
opportunity to
gain the
scale needed to compete
effectively with Google
by diverting bidding opportunities and
transactions to Google’s
ad exchange and away
from rivals who did not have a chance to
compete at all or
to compete on the same terms. It
also harmed publishers in the form of lower
revenues, limited the ability of advertisers to identify publisher inventory they valued most at the
best prices, and decreased the overall quality of matches between publishers and advertisers.
118.
Under
the waterfall setup,
rival ad
exchanges never had the opportunity to bid on
most impressions. If an ad
exchange earlier in the waterfall sequence submitted a bid above the
publisher’s price
floor, the ad server never offered the inventory to ad
exchanges lower in the
waterfall.
The rules
that
Google’s publisher ad server applied to Google’s
ad exchange, however,
provided Google’s
ad exchange
the opportunity to bid on every
eligible
impression, armed with
substantial data on the
publisher’s inventory and the
competitive landscape. Because rival ad
exchanges were relegated to the waterfall
process, unlike Google’s ad exchange, they had limited
windows into the universe of publisher inventory
available and lacked the
valuable
data on
available inventory
and competition that
Google harvested.
By preventing publ
ishers from freely
51
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 56 of 153 PageID# 56
multi-homing and seeing real-time bids from multiple ad exchanges, Google deprived publishers
of the benefits of full competition between ad exchanges. Likewise, by providing Google’s
ad
exchange with a preferentialand
for many impressions, sole—opportunity to buy publisher
inventory, Google discouraged advertisers
from multi-homing among a
d exchanges and provided
a substantial competitive advantage to buyers on Google’s
ad exchange, the
largest buyer being
Google Ads.
119.
In addition, through dynamic
allocation, Google’s
ad exchange h
ad the
opportunity
to win impressions whenever it matched a rival’s
average price. This permitted
Google’s ad exchange
(and its largest buyer, Google Ads)
to win more impressions than its
rivals, especially higher-value impressions. But for dynamic allocation, a rival ad exchange
might have won the impression because it could offer
a higher price or better match. Over time,
this distortion of the auction process meant
that advertisers
were more likely to
win
the
impressions
they most wanted through Google’s
ad exchange
as compared to a rival ad
exchange.
As a result, rival exchanges
struggled to
attract
advertiser
ad campaigns, which in turn
made it difficult for them to amass publishers willing
to offer their inventory
through the
ad
exchange.
Of course, dynamic allocation also hurt
Google’s own publishers, by sacrificing the
fees they paid Google to maximize the value of their advertising inventory.
120.
In 2014, Google expanded and further
entrenched
its artificial advantages by
introducing “enhanced”
dynamic
allocation, which remains in place today. This update allowed
Google’s ad exchange to obtain the benefits of dynamic allocation over inventory potentially
covered by direct
contracts between publishers and advertisers. Historically, this inventory was
not offered to
ad exchanges at all because qualifying inventory
was set aside to fill the direct
contract; only after the
direct
contract was filled
did ot
herwise qualifying inventory
become
52
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 57 of 153 PageID# 57
available for auction. Enhanced dynamic allocation afforded Google’s
ad exchange a right of
first refusal over this inventory
regardless of whether the publisher had yet
fulfilled the terms of
the direct contract. Enhanced dynamic allocation allowed Google’s
ad exchange to win the
impression as long as it was willing to pay more than Google’s own
estimate of the “value” of
fulfilling the terms of the direct contract at that moment, which Google calculated
through an
opaque process that predicted the likelihood the
publisher would still be able to satisfy the terms
of the direct
contract through future impressions even if Google’s
exchange filled the one
currently available. At the same time, Google ensured that “[i]t [was]
not possible for
publishers
. . .
to deactivate Enhanced
Dynamic Allocation
within the
publisher
ad server.
121.
Combined, dynamic allocation and enhanced dynamic allocation push more
transactions through Google’s
ad exchange by unfairly tilting the playing f
ield in Google’s favor,
driving additional
scale benefits available only to
Google.
Because of the exclusive link between
Google’s ad exchange and its market-leading publisher ad server, no rival
can
offer publishers or
advertisers the same terms as Google. The benefits to Google, and only
Google, are plain.
122.
First, Google
has
been
able to apply its substantial 20% revenue share fee
at the
ad exchange level over more transactions, boosting Google’s revenues and profits. This fee
has
been
earned not only on transactions where Google Ads won, but also on t
ransactions where
other Google and non-Google
advertiser buying tools won. Because Google could capture these
higher
revenues at the ad exchange level, Google was able to forgo or heavily discount the fees it
otherwise might
charge for publisher ad server serviceshistorically much smaller than ad
exchange fees.
Indeed, for many
customers, Google completely waived publisher ad server fees
on a given transaction if it was able to charge its 20% ad exchange fee.
By
extracting higher
fees
at the ad exchange level than at the publisher ad server level—which Google needed to control to
53
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 58 of 153 PageID# 58
force more transactions to its ad exchange—Google
has also able to maintain low ad serving fees
while still achieving its margin
goals across the
ad tech stack. This fee structure discourages
entry by
potential ad server competitors, because
entry could only be
economically feasible by
replicating Google’s overall strategy: building dominant positions at each level of the ad tech
stack and forcing more transactions to flow through those tools.
123.
Second, by forcing more
transactions through Google’s
ad exchange
and away
from rivals, Google
has
distorted the pathways through which publishers and advertisers transact
and impeded the ability of competitors to gain the scale necessary to compete effectively in the
ad exchange market. Google’s dynamic allocation and enhanced dynamic allocation programs
have decreased the likelihood that a rival ad exchange could win a transaction, even if it had an
advertiser willing to pay
the most for an impression. In turn, this
has
diminished the ability of
ad
exchanges to attract additional publishers and advertisers to their platforms
and has
deprived
them of valuable transaction data that could improve their competitiveness.
124.
Third, by
giving Google’s ad exchange
(and only
Google’s ad exchange) a
“first
look” option of
purchasing publisher impressions offered for sale through DFP, Google
has
limited the ability of publishers to freely
and effectively offer their impressions for sale on
multiple ad exchanges. Dynamic allocation and enhanced dynamic allocation
has
resulted in a
two-tiered systema special auction where Google’s AdX competed and a
secondary, inferior
auction potentially available to rival exchanges. Publishers
are
unable to partner with Google’s
rival ad exchanges on the same terms as Google’s
AdX. Those rivals cannot integrate with DFP
via a mechanism equivalent to dynamic
allocation, even if they had the technological capability
to do so.
54
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 59 of 153 PageID# 59
125.
Even though Google modified the way dynamic
allocation operated in late
2019,
the effects of the decade-long program persist. Over that period, Google
has
amassed
substantial
scale within its ad exchange
while undercutting rivals’ ability to do the same. The flywheel
network effects of that scale continue to advantage Google’s ad exchange, especially
when
combined with the new algorithmic bidding programs described below that largely replicated the
effect of dynamic allocation.
Even today, Google
continues to use enhanced dynamic
allocation
to favor buyers transacting through Google’s platforms. Only those buyers
can bid with
knowledge of the
Google-determined
price floor that
Google
sets
through enhanced dynamic
allocation.

Google’s Dominance Across the Ad Tech Stack Gives It the Unique
Ability to Manipulate Auctions to Protect Its
Position, Hinder Rivals,
and Work Against
Its Own Customers’ Interests
126.
In addition to restricting
vital Google Ads
demand to website publishers using
Google’s publisher ad server and ad exchange, Google realized it also could manipulate Google
Ads’ bidding strategy to further entrench its publisher ad server
and make
entry by
competing ad
servers unworkable.
Google Ads ostensibly bought inventory on behalf of its advertisers using
price and budget limitations decided by each advertiser. But Google
chose
to do so in ways that
served Google’s long-term goal of dominating publisher platforms.
55
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 60 of 153 PageID# 60
Fig. 10
127. Google Ads’ advertisers set maximum prices,
13
budgets, and other parameters for
their campaigns, but Google Ads is otherwise a “black box” to advertisers. Google has nearly
full control over when, where, and how Google Ads bids for its advertiser customers. Using that
control, Google designed a system intended to force Google Ads’ two million advertisers to pay
higher advertising prices. The goal and effect are clear: increase payouts to publishers using
Google’s platforms—the only place Google Ads’ demand was available—to make Google Ads’
advertising demand and Google’s publisher ad server and ad exchange even more indispensable
to publishers (while also allowing Google to maintain its supra-competitive take rates). In doing
so, Google foreclosed the ability of rivals to compete effectively against its publisher ad server
business and further propelled Google’s DFP ad server from a dominant platform to a monopoly.
128. Over time, as Google’s monopoly over the publisher ad server was secured,
Google surreptitiously manipulated its Google Ads’ bids to ensure it won more high-value ad
13
Although advertisers set a maximum price for advertising (generally on a per click basis),
Google actually charges advertisers the lower of 1) their maximum price or 2) Google’s cost plus
a set margin.
56
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 61 of 153 PageID# 61
inventory on Google’s ad exchange while maintaining its own profit margins by charging much
higher
fees on inventory
that it expected to be less competitive. In doing so, Google
was able to
keep both categories of inventory
out of the hands of rivals by competing in ways
that rivals
without similar dominant positions could not. In doing so, Google preserved its own profits
across the ad tech stack,
to the detriment
of publishers. Once again, Google engaged in overt
monopoly
behavior by
grabbing publisher
revenue and keeping it for itself.
Google
called this
plan “Project Bernanke.”
a)
Google
Works
Against
the Interests of Its Google Ads
Customers By
Submitting
Two
Bids Into AdX Auctions
129.
Google
Ads determines how to bid on behalf of its advertisers using price and
budget maximums decided by the advertiser. For
each piece of
available inventory, Google Ads
runs an internal auction of Google Ads’
advertisers,
based on an algorithm that considers
eligible
advertisers
specified maximum cost-per-click prices, Google’s predictions of the likelihood of a
user clicking an ad, and a number of other
factors. These bids are then converted into a cost-per-
impression (“CPM”) bid, which, until 2013, Google then adjusted downward to ensure Google
Ads would charge an expected 14%
take rate on each impression—in addition to the 20%
take
rate charged by
Google’s ad exchange. If Google
Ads then won the impression—and the user
ultimately clicked on the
ad—the Google Ads’
advertiser would pay the
amount paid for the
impression plus Google’s
fee.
130.
Until late 2019, AdX operated what was known as a second-price auction. In
a
second-price auction, the advertiser with the highest bid wins the right to display its ad on the
publisher website. The winning advertiser, however, only pays
one
cent more than the price of
the second-highest bid, and gets to keep the
difference between the two
as an
“auction discount.”
57
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 62 of 153 PageID# 62
If the advertiser is the only bidder, then it must pay
only the minimum price the publisher agreed
to accept, known as the price floor.
131.
Because of this auction dynamic, advertiser buying tools have
an incentive
to
submit only one bid into an ad exchange’s auction. If an advertiser buying tool submits two bids
into a second-price auction, the higher bid might win the auction while the lower bid sets the
price; without the second bid, the inventory might
have been sold to the winning advertiser at
a
lower cost (possibly even at the
floor price set by the publisher).
In essence, the second bid into
the auction only serves to drive the final auction price upwards, while conveying no real
increased chance of
winning.
132.
To avoid driving up the
cost of advertising, non-Google advertiser buying tools
only submitted a single bid into AdX auctions. But Google took a different
approach for Google
Ads and, unknown to advertisers,
submitted
two
bids from Google Ads’
advertisers into the AdX
auction. This was contrary
to the interests of Google Ads’
advertisers—who benefited when
Google
Ads paid less for
impressions resulting in clicks—but furthered Google’s
goal of locking
publishers into its ad exchange and publisher
ad server. These higher payouts for publishers on
Google’s platforms were
a key part of Google’s overall strategy to prevent new publisher ad
servers
from entering the market and to increase the stickiness of Google’s own publisher ad
server by
raising publishers’ switching costs. The strategy
allowed
Google
to extract additional
margins
across the
ad tech stack through the two-tiered auction structure described above. A
publisher that left Google’s platform not only lost access to all of the unique advertiser demand
available only on Google Ads, but also lost access to an advertising buying
tool willing to
overcharge its advertisers to benefit its publishers.
58
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 63 of 153 PageID# 63
133.
Google
generally did not
disclose to Google
Ads’
advertisers the
fees
that Google
extracted from their ad purchases. Even when it did publicly disclose average fees
from the
perspective of the revenue received by publishers, it did not disclose that those
fees
came on top
of advertising prices
that were inflated
by virtue of Google
Ads’ bidding practices. This obscured
the total “take rate” Google was keeping
for itself, making it difficult for
advertisers to compare
Google
Ads to any potential c
ompetitor.
134.
Google’s internal analyses confirm the purpose
and effect of Google
Ads’
double-
bid policy. A
2013 s
tudy
found that Google Ads submitted the top two bids
in 85%
of the
auctions it won, meaning its bids set the price in the vast majority of auctions it won. Because
Google
Ads did not face
meaningful competition for its advertising c
ustomers, however, this
statistic did not lead Google to reduce its advertisers’ bids or otherwise
adjust its bidding
strategy. Rather, the study
confirmed Google’s understanding that it had full control and pricing
power over a unique pool of advertiser demand that was often interested in inventory
other
advertisers did not or could not value in the same
way. As Google itself
acknowledged, Google
Ads had “no margin or inventory sourcing constraints” so it was able to “establish[] processes to
tune margins in the backend,” outside auctions. As usual, what mattered most was Google’s own
dominance, not its customers’ best interests.
135.
Years later, little
had changed
when Google
revisited the question of what
would
happen if Google
Ads submitted only one bid into the AdX auction.
14
The answer: the 30 t o 40%
boost in publisher revenue from Google’s two-bid strategy would disappear. Strikingly, the same
analysis showed that if Google Ads submitted only one bid on AdX—and thereby was able to
14
On the limited occasions where Google Ads bids on inventory on third-party exchanges, it
submits only one bid.
59
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 64 of 153 PageID# 64
buy inventory at lower prices—its profits on Google Ads would increase by an astonishing 50%
in the short run.
Fig. 11
136. But Google simply could not risk a change that weakened its ability to keep
publishers locked into its publisher ad server and ad exchange. The loss of inflated publisher
revenues on Google’s platform might finally make a rival publisher ad server an attractive
alternative and threaten Google’s monopoly. If publishers switched, Google would lose control
over the ad selection process and be forced to interoperate with those rival products for
inventory.
b) Google Manipulates Its Fees to Keep More High-Value Impressions
Out of the Hands of Rivals
137. As Google’s publisher ad server monopoly was being cemented, Google’s focus
shifted to ensuring its ad exchange rebuffed growing challenges from rival ad exchanges.
Recognizing that Google Ads still f aced little competition for most impressions it won on AdX,
over time Google adjusted its fees—and in turn its bids—to ensure it could win more high-value
60
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 65 of 153 PageID# 65
transactions
while paying less for
lower-value
transactions. B
y owning both the dominant
publisher ad server and the dominant ad exchange, Google had unique access to the price data it
needed to make these adjustments in a way that ensured more transactions, revenue, and profits
flowed to Google—and in particular its Google Ads’
ad network and ad exchange—with
minimal risk
to Google.
138.
First, i
n January 2013, through a program called Dynamic Revenue Share, Google
adjusted the way
Google Ads
took its revenue share fee
from a
fixed 14%
take rate on each
impression sold to a changing, or dynamic, fee that averaged 14% per publisher over time. This
allowed Google Ads to effectively increase its bids in competitive auctions (by taking
a lower
expected
fee) and make up the losses by setting a higher
expected
fee on non-competitive
auctions. This change
reinforced Google’s ability
to w
in more transactions
on its ad exchange
than could rival ad networks
or demand-side platforms, augmenting the
advantages Google
already
afforded its ad exchange through dynamic allocation, without the need to
compete by
reducing
its fees.
139.
Second, later in 2013, Google implemented Project Bernanke,
15
which doubled-
down on Dynamic Revenue Share by subsidizing bi ds (i.e., bi dding above the advertiser’s
willingness to pay) on competitive impressions, thereby sacrificing any profit on the transaction.
Of course, Google ensured that its own margins would be maintained. Google offset any loss on
a given transaction by charging much higher fees (i.e., 50% or more) on impressions where
Google Ads faced no competition—the majority of impressions Google Ads had already been
winning. In doing so, Google Ads and AdX were able to win more impressions over their
15
Project Bernanke was named after former Federal Reserve Chairman Ben Bernanke because it
resembled “quantitative easing on the Ad Exchange.”
61
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 66 of 153 PageID# 66
respective rivals,
increasing
Google Ads
spend by 20% and profits by 30%,
and increasing
overall
ad exchange
revenue by 8%. A
Google
simulation of the program confirmed
that
advertisers using
non-Google
buying tools
won fewer of the
coveted high-value impressions,
decreasing their relatively
smaller spend on AdX
by 14%.
140.
Finally, in 2014, Google
implemented ProjectGlobal Bernanke”
which changed
the method by which Google calculated
the Google Ads’
take rate (sometimes referred to
as
“margin”).
Instead of
applying the same take rate to each publisher’s ad inventory, Google took
an average take rate at the ad exchange level. Google took a higher cut of
advertiser spend
for
some publishers while taking less for others. T
he
effect was to further shift the publisher benefits
of Google Ads’ two-bid system
to the most important publishers
and away from
“non-
competitive
publishers
(i.e., publ
ishers whom
Google believed were unlikely to risk switching
to a rival ad server). Google
candidly acknowledged that by 2014 it was not worried it might lose
“non-competitive publishers.”
As one document explained, it is “unlikely they
can do better on
another network (which doesn’t have
any [Google Ads] demand).”
141.
The Google-generated graphic below shows Dynamic Revenue Share and Project
Bernanke in practice. After
running its internal auction (as described above),
Google Ads
calculates its two highest bids on a CPM basis as $1.00 and $0.96 (the
gray bars).
These bids
might be similar
because they
are based on the same Google targeting data. Applying a uniform
14%
take rate (or
“margin”)
would result in bids equal to $0.86 CPM and $0.83 CPM. With
dynamic
revenue share, Google
adjusted the bids
to $0.95 CPM and $0.83 CPM (the red bars in
the Figure). For Bernanke, Google raised the first
bid even further
(sometimes substantially),
as
the first bid determines the winner of the auction.
By raising the first bid
(here from $0.95 CPM
62
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 67 of 153 PageID# 67
to $1.20 CPM, the green bars), Google Ads won more auctions, either clearing publishers’
reserve price more often or winning against a rival’s bid for competitive impressions.
Fig. 12
142. By manipulating the auctions in this fashion, Google was able to subsidize the
inflated advertiser bids by dropping the price of the runner-up’s bid ( here from $0.83 CPM to
$0.48 CPM). Where an auction was not competitive—the majority of auctions that Google Ads
wonthe lower price was the one Google Ads paid for the impression. Google then kept the
margin (an estimated 50% in the example) to subsidize competitive queries. In this example,
instead of the website publisher receiving $0.83 CPM for the advertisement, it received only
$0.48 CPM for the impression under Bernanke, assuming only Google Ads’ advertisers
submitted bids. A similar drop in price would occur for other “non-competitive” impressions. At
the advertiser level, Google aimed for the same average take rate for each Google Ads
advertiser: a 32% difference between what the advertiser paid to Google and what Google ended

up paying to publishers for all of the impressions that the advertiser purchased.
16
Bernanke
increased the number of transactions that Google won through its platforms, and in turn
increased Google’s overall revenues and profits while denying scale to competing ad exchanges.
143. Project Bernanke allowed Google Ads to continue to pass along additional
revenue to publishers on Google’s platforms (the only place it ran) but did so disproportionately
relative to the competitiveness of the publisher. In doing so, it won more high-value impressions
on Google’s ad exchange and reinforced the stickiness of Google’s ad server for key publishers.
Other ad exchanges and ad servers that lacked a captive source of advertiser demand whose bids
they could manipulate were unable to subsidize important publishers in the same way, presenting
another roadblock to entry or expansion in the publisher ad server and ad exchange markets. For
their part, while Google Ads’ advertisers won some additional competitive impressions, they did
not receive the full benefit of the lower prices Google Ads paid for non-competitive inventory.
Moreover, Google did not disclose to advertisers that it was shifting savings away from them to
increase its own margins. In effect, Google fended off competition that could have challenged its
monopoly power to force advertising transactions through its own ad tech products and limited
publishers’ and advertisers’ ability to multi-home with rival products while still being able to
maintain its high overall margins. In essence, a win-win, but only for Google.
144. In terms of its impact on competition, Google’s dynamic allocation and dynamic
revenue sharing programs functionally made price competition among rival ad exchanges
obsolete because no rival had sufficient scale across the ad tech stack to compete against Google.
16
Google Ads’ advertisers specify a maximum cost-per-click they are willing to pay. Google
charges advertisers a fee on top of the price that Google pays for publisher inventory. The result
is often less, and “sometimes much less,” than the advertiser’s specified maximum.
64

Google
could effectively
afford to charge nothing w
here it wanted to obtain high-value inventory
because it had the ability
to make up the difference on the back end with
less valuable inventory.

Google
Buys and Kills
a Burgeoning Competitor
and Then Tightens
the Screws
145.
By 2010, Google’s
rivals had begun to design and market technology in an
attempt to circumvent the limitations on competition that Google imposed
through its
publisher
ad server. Google’s
response was forceful, extinguishing the leading innovator via acquisition
and tightening its restrictions to head off similar potential threats. Google continued to impede its
rivals’ ability to offer real-time competition for publisher inventory on the same playing field as
Google’s ad exchange. Google used anticompetitive means to keep customers on both sides of
the stack (i.e., publishers
and advertisers) locked in to its ad tech tools, while ensuring that
competitors for those valuable customers were locked out.
1.
Google Extinguishes AdMeld’s
Potential Threat
146.
In 2011, Google acquired a competitor, AdMeld. In doing so, Google removed
from the market what it viewed as a “critical threat” to
its ad exchange and publisher ad server
businesses. AdMeld’s
yield management technology could receive bids
in real
time
from
multiple
ad
exchanges
and other demand sources. This could allow other ad exchanges to
compete in the same way Google’s
publisher ad server allowed Google’s
ad exchange to
compete through dynamic allocation, utilizing in part a real-time bidding standard. Publishers
quickly moved to adopt
the yield management
technology
because it
allowed them to multi-
home
more effectively
among ad exchanges and ad networks.
It also gave
publishers
the ability
to connect
with the
advertisers
who especially valued their
inventory.
In contrast, Google’s
publisher ad server did not permit connections to any
advertising demand source other than the
buyers on the
AdX
ad exchange, which of course
included Google Ads’
advertiser base. Quite
simply, AdMeld threatened to destroy the
advantage Google had
created for itself in its
65
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 70 of 153 PageID# 70
exclusionary
publisher
ad server
by
allowing
website creators to offer their digital advertising
inventory to multiple ad exchanges in order to find the best available match.
147.
Externally, AdMeld described itself as “the largest, independent practitioner of
RTB [Real Time Bidding] behind Google,”
“connect[ing] to more than 200 ad networks, & 35
Demands Side Platforms (DSP) and process[ing] more than 11 billion bids daily”
with links to
20 leading data providers. Relying on its “core functionality” of
real-time bidding, AdMeld
proposed becoming its customers’ “central ad decision hub,” the key
role
Google
reserved for its
own publisher ad server
product.
148.
In a 2010 strategy discussion, Google
executives noted that “Yield Managers are
a threat we need to take very
seriously” with “AdMeld [being] the largest
concern” and one of
three “Key competitors.” Specifically, if AdMeld continued to attract publishers to its
technology, Google worried about the possibility
of having to “pass real-time AdX pricing into a
non-DFP ad server.” If Google were
forced to do so, it would eliminate DFP’s exclusive access
to AdX, which Google believed would be—and which ultimately was—the key to DFP’s
growth
and enduring dominance.
149.
AdMeld typically
charged only a 7% revenue share compared to Google’s 20%
revenue share on AdX. So rather than compete with AdMeld, what did Google do?
It bought and
buried it.
In
a presentation outlining the “Strategic Rationale” for the deal,
Google executives
explained
that the acquisition would “reduce [the] risk of disintermediation,”
i.e., the possibility
publishers and advertisers would transact through rivals. Disintermediation
at any level
of
the ad
tech stack
was a serious threat
to Google’s
entire strategy of being the sole
entity with end-to-end
control over digital advertising transactions.
66
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 71 of 153 PageID# 71
150.
In other documents evaluating whether to buy a
yield manager like
AdMeld,
Google
candidly acknowledged that the underlying “technology is irrelevant to us.” Google
already had in place the only
yield management tool it wanted
publishers to use: dynamic
allocation’s real-time bidding integration with Google’s
ad exchange. Google
also recognized
that its customer
base al
ready largely overlapped,
“so we aren’t buying customers.” Only one
real question remained open for Google:
“How does the competitive landscape change if we buy
one?”
151.
The Antitrust Division investigated the
AdMeld deal before it closed.
Like the
FTC considering the DoubleClick acquisition, the Antitrust Division declined to challenge the
deal based on assumptions
about the ad tech market that, w
ith the benefit
of hindsight,
were
incorrectin
no small part due to G
oogle’s subsequent anticompetitive conduct. At the time, the
Antitrust Division cited
multi-homing among display
advertising platforms as a factor that
“lessens the risk that the
market will tip to a single dominant platform.”
But
Google’s increasing
scale and dominance across the ad tech stack, coupled with its subsequent exclusionary conduct,
destroyed the ability of advertisers and publishers
to effectively multi-home
among alternative ad
exchanges. As a result, the market tipped and AdX became the dominant ad exchange.
152.
Shortly after the AdMeld deal closed, Google
combined the yield management
functionality
of AdMeld into DFP
and migrated all AdMeld customers to
AdX. Critically, it then
shut down AdMeld’s nascent real-time bidding technology, quashing
a competitive threat that
otherwise might have
challenged
Google’s market position
and
forced Google to move toward a
more open system that allowed publishers to utilize AdMeld’s innovative technology
to facilitate
real-time competition among
non-Google
ad
exchanges and
advertisers.
67
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 72 of 153 PageID# 72
153.
By acquiring
AdMeld, Google
eliminated the existing competition between
AdMeld and Google’s
sell-side products, foreclosed any potential competition, and helped
eliminate the leading
yield management technology
that Google knew might displace its
dominant market positions.
2.
Google Doubles
Down on Preventing Rival Publisher Ad Servers from
Accessing AdX and Google Ads’
Demand
154.
After acquiring and killing AdMeld’s innovative technology in order to prevent
publishers from having the opportunity to experience real-time competition between Google and
rival ad exchanges
and publisher ad servers, Google clamped down on similar attempts by
publishers to allow Google’s ad exchange to integrate with rival publisher
ad servers.
155.
By 2015, Google’s
publisher
ad server, DFP,
had
reached a 90%
market share and
had snuffed out most meaningful
competition.
In part because of
the scale
that Google’s
publisher
ad server
had achieved by excluding c
ompetitors, Google’s
ad exchange was
large and
growing quickly;
Google Ads
likewise
remained the dominant advertiser
ad network and an
especially valuable
source of advertising demand f
or many
publishers. E
mboldened by its
success, in 2014 Google
changed the
AdX terms of service to further
entrench its market power.
Those changes prohibited publishers from using non-Google ad servers, or
the remaining
yield
management solutions, t
o compare bids from Google’s ad
exchange with
bids
from other ad
exchanges in real
time, notwithstanding the increased access to inventory such an integration
could provide to advertisers buying on AdX.
In
effect, Google decreed that any publisher
that
wanted real-time
competition involving
AdX would have to use Google’s publisher ad server,
68
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 73 of 153 PageID# 73
DFP, formally cementing in policy what Google had intended from the outset of its relaunch of
AdX in 2009.
Fig. 13
156. Google’s decision was bad for publishers, locking them into a less innovative
publisher ad server with artificial limitations on real-time price competition for advertising
inventory. It was also bad for any would-be publisher ad server rivals—effectively sounding the
death knell for future publisher ad server competition. Google’s exclusionary policy effectively
prohibited a competing publisher ad server from offering any form of real-time competition that
included Google’s ad exchange and the unique advertiser demand that came with it. Forgoing
such competition was a non-starter for nearly all publishers. This restriction is still in place
today, an insurmountable obstacle for any nascent publisher ad server competitor.
157. Google built a wall around its exclusive link between its publisher ad server and
ad exchange because it feared competition. In particular, Google feared a rival could offer a
more attractive publisher ad server by simply allowing all advertiser demand to compete in real
time on a level playing field for publisher inventory. More demand competing in real time for
69
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 74 of 153 PageID# 74
publisher inventory
generally increases
the likelihood that
the advertiser that is willing to pay the
most for an impression will have a chance to buy it. Rivals that offered technology upending this
policy would be seen as
offering a better
publisher
ad server. As one Google employee wrote, if
another
publisher
ad server could place Google’s ad exchange in real-time competition with
other ad exchanges, that
ad server
could offer publishers a “super set of demand” and “[n]o one
would sign up for
AdX directly” through Google’s
publisher
ad server.
158.
Even though bot
h publishers and advertisers benefit from real-time competition
between AdX and other ad exchanges,
by policy,
Google
limited
real-time competition
from
rival ad exchanges
to maintain its dominant positions at both ends of the ad tech stack and to
further insulate its
growing position in the ad exchange market. Google’s
decision was based on
business, not technology.
As the lead architect of
AdX explained in an internal email about the
policy, “Our
goal should be all or nothing
– us
e AdX as
your SSP [ad exchange] or don’t
get
access to our demand.”
Indeed, Google
had already
worked quietly to develop the technology
that might a
llow AdX to
integrate in real time
with non-Google publisher ad servers. But Google
made a “strategic decision” to prohibit such integrations via contract; it terminated its internal
projects and blocked efforts by rivals and publisher customers to implement such integrations.
That prohibition endures
today, and both publishers and advertisers are paying the price for
Google’s
anticompetitive
refusal to innovate or integrate.
159.
Now, the only
way a publisher can access Google’s ad exchange outside Google’s
publisher
ad server is by
placing a
n “AdX Direct”
tag on the publisher’s website. Even though
these tags could benefit buyers on Google’s
ad exchange by providing access to additional
publisher inventory, Google designed the
tags
to discourage
publishers
from using them. They
offer only the most rudimentary functionality: publishers can send a request to Google’s ad
70
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 75 of 153 PageID# 75
exchange
with a price floor, and if there is an advertiser
on AdX
willing to
pay that price or
higher, Google’s
ad exchange
wins the inventory. No other competing bids
are considered, and
Google’s bid cannot be
compared to other
ad
exchanges’ bids.
160.
Recognizing that AdX Direct is an antiquated relic in comparison to real-time
bidding, Google
even
planned to eliminate the tag
entirely in 2019. Google
later
paused that
project as antitrust enforcers focused their
gaze on the company’s digital advertising business.
But Google has not retained
AdX Direct
because it is
a competitive product offering
valued by
publishers. Rather, in the words of
a Google employee, it
merely
serves as
“a concept for
antitrust”—something Google’s
antitrust lawyers
could claim offers
rival ad servers some remote
chance of competing on the merits with Google’s
ad server. Google’s internal analyses of
AdX
Direct, however, reflect publishers’ reality: Google’s restrictions make impossible any
reasonable substitute for
the real-time integration with Google’s ad exchange
available
exclusively
through Google’s
ad server.
3.
Google
Manipulates
Google Ads’ Bidding Strategy
to Block Publisher
Partnerships with Rivals
161.
Google
also took the opportunity to tweak its Project Bernanke algorithm to
further lock in publishers who considered using innovative bidding technology offered by
Google’s rivals. Some publishers attempted to partner with rival ad
exchanges to offer them
“first look” access to inventory—an opportunity to bid in real time for inventory before it was
offered to Google’s AdX. “First look” could potentially prop up rival
ad exchanges by
giving
them effective access to some of the most valuable inventory.
17

Previously, Google used dynamic allocation in its publisher ad server to exclude rival
exchanges from meaningful competition. By only permitting Google’s own ad exchange to bid in
real timeahead of any other exchange—for impressions, Google was unfairly advantaged and
competitors were effectively stymied from competing.
71
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 76 of 153 PageID# 76
162.
Beginning in 2014, Google
recalibrated
the earlier Project
Bernanke to decrease
Google Ads’
bids
on AdX for
publishers
that
allowed
rivals an opportunity
to buy inventory
ahead of
AdX.
Google
called this “Project Bell.”
Where publishers tried to partner with rival
sources
of
advertising demand for “first look” access to inventory, Google reduced bids
without any input from or awareness of the underlying advertiser—by about 20%. According to
Google’s documents, it
explicitly
warned publishers that utilizing innovative “first-call”
technology
from rivals would cause publisher
yield to drop 20 t
o 30%. O
f course, only
a
company like Google with substantial market power across the entire
ad tech stack would have
the incentive or ability to implement such a program. Project Bell both insulated Google’s ad
exchange from this new form of competition and preserved preferential access for buyers on
Google’s ad exchange, including Google
Ads.

Google Responds to the Threat of Header Bidding by Further Excluding Rivals
and Reinforcing Its Dominance
1.
The Industry Attempts to Rebel Against Google’s Exclusionary Practices
163.
By 2015, Google’s publisher
customers and ad exchange competitors had grown
so frustrated
with
Google
that they attempted to implement a form of open, real-time competition
with Google’s ad exchange that evaded Google’s
exclusionary
restrictions. This
innovative
technology
was called header bidding.
164.
Header bidding w
orked as follows: publishers inserted certain computer
code into
the “header” section
of the HTML code of
a web page. This code triggered
a real-time auction
among
ad exchanges
before
the publisher’s web page called the
publisher
ad server.
18
The
highest bid from the header bidding a uction was then sent to the publisher’s ad server. Because
18
Because early versions of the header code were run on the device of the user, or client, they
were referred to as “client-side” header bidding.
72
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 77 of 153 PageID# 77
of the way Google configured DFP, the winning bid from the header bidding auction was
then
sent to Google’s ad exchange
to see if it could beat that price. Critically, through dynamic
allocation, Google’s ad exchange
always
received this “last look” advantage, essentially a right
to buy any
impression as
long as it had at least one advertiser willing to
match the competing bid
price from the header bidding auction.
165.
As originally designed, header bidding had limitations that stemmed from
Google’s restrictions on how publishers could sell their inventory through Google’s
publisher
ad
server. For
example, publishers had to configure thousands of entries into the
publisher
ad server
and recode their pages to implement
a
workaround t
o enable
header bidding. Web pages also ran
somewhat
more slowly
because publishers had to run multiple
auctions sequentially: the header
bidder auctions first, and then Google’s ad
exchange auction, which
always ran last. Despite
these limitations, for the first time, Google’s ad exchange was forced to
compete, at least
in some
fashion,
against real-time bids from rival ad
exchanges
rather than against static, historical
average prices from those ad exchanges. In assessing the impact of header
bidding, a
2016
Google
internal presentation noted “header bidding and header wrappers
are BETTER than
[Google’s platforms] for buyers and sellers.”
Google explained that
competition between AdX
and buyers using header
bidding
increased publisher revenues
by 30
to 40%, and provided
additional transparency to advertisers.
In essence, header bidding allowed publishers, advertisers,
and Google’s rivals an opportunity to at least partially circumvent Google’s restrictions
against
real-time competition.
Market participants
had demonstrated their preference for improved
choice, flexibility, and competition, even if it came at the cost of burdensome computer
workarounds
and slower
load times for end users.

Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 78 of 153 PageID# 78

166. In practice, header bidding dramatically improved the competitiveness of rival ad
exchanges. Header bidding provided a real opportunity for rival ad exchanges to see and
compete for more publisher inventory, and potentially gain scale to compete effectively with
Google. By allowing a publisher to call multiple ad exchanges in real timeeffectively multi-
homing at the ad exchange level—header bidding vastly increased the amount of inventory rival
ad exchanges could offer their advertisers. In turn, advertisers had the opportunity to see and bid
on more inventory—potentially through lower-cost channels than Google’s ad tech tools—
increasing their chances of winning inventory. By improving the ability of advertisers and
publishers to connect, these rival ad exchanges were able to clear more transactions, increase
19
“SSPs” refers to non-Google ad exchanges.
74
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 79 of 153 PageID# 79
revenues
for publishers, and improve the quality
of matches. In turn, header bidding had the
potential to attract more
advertisers
and publishers to these
rival ad
exchanges by increasing the
incremental value
they could offer.
167.
Due to this increased competitiveness, non-Google affiliated buyers began to buy
more advertising inventory through third-party ad exchanges using header
bidding. Google’s
internal analysis showed a deceleration in spend by
non-Google advertiser
buying tools on AdX
as “header bidding removed AdX inventory
exclusivity . . . [
and]
buyers shift[ed] spend as other
inventory sources delivered equal/better value.” A large buyer explicitly indicated to Google that
they were
“shifting spend over
to HB partners
because they
were
seeing better performance.”
168.
More transactions flowing through rival ad
exchanges made it easier
for those ad
exchanges
to offset the massive cost of processing
billions
of ad requests each day;
ad
exchanges
are only compensated for requests that result in a won transaction. These new transactions also
provided ad
exchanges
with additional data on the universe of publisher inventory, user targeting
data, and the competitive landscape.
169.
Building on the success of early
client-side header
bidding, several companies
invested to develop new innovative
free
or low-cost
tools (called “wrappers”) that
enabled
“server-side” header bidding. This
new
form of header bidding allowed the
header of a web page
to call a single server, which then sent calls to multiple ad exchanges, each of which returned a
bid to the
server, which in turn passed on the winning bid to the
web page. Server-side header
bidding turbocharged the scale benefits of header
bidding by decreasing integration costs and
improved the internet user experience by
reducing l
atency introduced by header bidding.
170.
Internally, Google recognized
that
header bidding substantially benefited every
market participant
except
one:
Google. For that reason, Google refused to participate
and instead
75
chose to stifle any competitor that dared employ header bidding. As one Google employee
explained, “[Header bidding] gives many publishers better
yield, so it’s a no-brainer for a
publisher to adopt it.” A late 2015 internal discussion somberly noted that Google
“[did] not
have incredibly
robust arguments to discourage header bidding” and conceded
that header
bidding offered the
competition Google had publicly preached but privately
precluded:
With AdX we’ve always
advocated the more competition a pub has
being
considered
with real time price competition the better the
yield.
Our competition is using t
his same argument for why header bidding
makes sense.
If they can
submit a near real time price into DFP the[]
competition with AdX is improved.
As another Google employee observed, “[Google’s ad server] has historically made it difficult
for [ad exchanges] to compete on a level playing f
ield with AdX.”
171.
Google viewed header bidding—and particularly server-side header bidding—as a
direct and, in the words of a 2016 internal strategy paper, “existential threat” to the market power
Google
had amassed. Internal Google documents
confirm that Google understood header bidding
to be
a direct
response by its customers and competitors to
counteract
Google’s increasing
dominance and its “unwillingness to open our systems to the types of transactions, policies and
innovations that buyers
and sellers wish to transact.” Header bidding w
as an attempt to
“circumvent dynamic allocation,” one Google employee noted in late 2015. Another employee
recognized that “[p]ublishers felt locked-in by dynamic allocation in [Google’s
ad server] which
only
gave [Google’s ad exchange the]
ability to compete, so HB was born.” Another described
header bidding as
a “world of true, multi-sourced [real-time bidding]” without Google
as the
“authoritarian intermediary.”
172.
Beyond breaking the restrictions Google had put in place, header bidding also
represented a pervasive threat to Google’s market
power stemming f
rom its unique and
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 80 of 153 PageID# 80
76
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 81 of 153 PageID# 81
substantial advertiser demand. If header bidding could bring together a critical mass of non-
Google advertising demand into a single real-time auction (e.g., a server-side header bidding
auction), it might be able to undermine the power Google wielded through its Google Ads’
advertising demand, thereby weakening the need for publishers to use Google’s publisher ad
server and ad exchange in the first place.
Fig. 15
173. While header bidding w as an important step toward more competition among ad
exchanges, it could not displace Google’s dominance overnight. Google had hard-coded into the
ad selection rules of its publisher ad server several advantages for its own ad exchange that
would prevent rival ad exchanges from competing. Absent toppling Google’s monopoly position
in the publisher ad server market, header bidding could offer publishers and advertisers only
incremental gains. Thus, in the wake of header bidding, Google implemented still further
measures to limit the growth of both header bidding and the rival ad exchanges deploying this
technology.

2.
Google Blunts Header Bidding By
Drying
Out”
the Competition
174.
Google moved swiftly to respond to the perceived threat header bidding posed to
its ad exchange dominance and
publisher
ad server monopoly. Instead of leaning into the
increased real-time competition between
ad
exchanges spurred by header bidding—which would
have led to higher
revenue for publishers, lower ad tech fees, and better return-on-investment for
advertisers—Google adopted a multi-prong strategy
to forestall the adoption of header bidding
by publishers
and, as a Google partnership strategist phrased it in an internal email, “dry out”
rival ad
exchanges that
adopted header bidding.
175.
In doing so, Google
aimed to return to a more outdated, closed, two-tiered system
of competition for advertising transactions. Header bidding represented a real opportunity for the
market to move to a more open system where publishers could effectively
multi-home their
inventory
across
competing ad
exchanges and varied sources of advertising de
mand. Although
Google
realized that its original vision of all display
advertising transactions flowing through
Google’s ad exchange was no longer realistic, Google
also recognized it could take advantage of
its dominance at each layer of the
ad tech stack to impede publishers, advertisers, and rival ad
tech providers
from further opening up the ad tech ecosystem and loosening Google’s control
over where transactions flowed.
a)
Google Develops So-Called Open Bidding, Its Own Google-Friendly
Version of Header Bidding To
Preserve Its Control Over the Sale of
Publisher Inventory
176.
Employees
working on Google’s publisher-facing platforms responded to the
threat of header bidding b
y developing
a limited way for
rival ad
exchanges to finally
compete in
real
time within Google’s platforms, but on terms dictated by Google. Although Google
could
not return to a fully closed system of real-time bidding—one Google previously reserved for its
own ad
exchange via dynamic allocationit could create a system over which it retained control
78
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 83 of 153 PageID# 83
to dictate the terms on which competition occurred.
The mechanism, internally referred to
as
“Jedi,” came with a number of limitations designed to dampen competition and insulate
Google’s
ad exchange
from vigorous competition. T
o that end, as explained by Google’s lead product
manager
for DFP and AdX, Google intentionally designed this new form of
integration to be just
“slightly better” than early
versions of header bidding.
177.
Google called this mechanism “Exchange Bidding,” later renamed
Open
Bidding” (for simplicity, referred to herein as
“Open Bidding”).
Google started testing Open
Bidding in 2016 and formally launched the program in April 2018. Externally,
Google portrayed
Open Bidding
as
an improvement to header bidding that
created
a real-time
bidding auction with
multiple
ad
exchanges, similar to header bidding, but
on Google’s servers
to reduce latency.
It
represented the first time that Google’s ad exchange competed in real
time against other
ad
exchanges, as Google had previously
refused to participate in any header bidding auctions.
178.
Internally, however, Google understood that the purpose of Open Bidding w
as to
“stem[] the bleeding” and “combat the risk of header bidding.” Google understood that if it could
blunt header bidding’s momentum, it could maintain its “control point and advantage”
gained
through its
publisher
ad server monopoly and ultimately
“[g]et pub[lishers] to move away
from
header
bidding back into our platform.”
179.
Google outwardly portrayed Open Bidding a
s a more publisher-friendly way
for
participating
ad
exchanges to bid in real
time on publisher inventory, as Open Bidding
substantially reduced a publisher’s cost
to integrate
an ad exchange other than Google’s AdX
within DFP. By contrast, to utilize header bidding, publishers had to configure thousands of lines
of pricing rules in the
publisher
ad server and update each webpage with new code.
Google also
79
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 84 of 153 PageID# 84
offered to share
with participating Open Bidding
ad exchanges
its
“last look” advantage over
header bidding that dynamic allocation previously had provided only to Google’s
ad exchange.
180.
But Open Bidding a
lso came with major drawbacks for both publishers and
participating
ad
exchanges. Google handicapped rival ad
exchanges to
impair
their chances of
winning
impressions through Open Bidding, which otherwise might increase their
overall
attractiveness to publishers. Google did so in four pivotal, mutually
reinforcing ways.
181.
First, Google
extracted
for itself an additional fee on every transaction won by a
rival exchange, reducing
the net payout
publishers received from integrating with other
ad
exchanges. Google imposed a 5% fee on rival ad
exchanges’ transactions through Open Bidding,
effectively
lowering the
net bid of Open Bidding a
d exchange participants
by 5%
relative to
AdX’s bid. This additional 5% charge effectively
amounted to a 25%
or more increase in the
average
ad exchange
fee, making bids from rival ad exchanges much less attractive to publishers.
182.
Second, even if a rival ad exchange won an auction, the rival ad exchange
paid
Google, and Google paid the publisher. Publishers received payments and reporting r
elated to
Open Bidding-won advertisements from Google, not rival ad exchanges, decreasing the number
of touchpoints between r
ival ad exchanges and publishers. By taking control over the payment
and reporting functions, Google
effectively disintermediated rival ad exchanges from their own
publisher customers and, in the long-run, made it less likely publishers would view those
rival ad
exchanges as valuable partners and continue to use them.
183.
Third, if a rival ad exchange
also owned an advertiser buying tool (as
Google
did), that exchange could not allow its own advertiser buying tool to participate in Open Bidding
auctions. This decreased
the competitiveness of those ad exchanges
from the perspective of
publishers.
80
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 85 of 153 PageID# 85
184.
Fourth, through Open Bidding, Google was able to increase its data advantage by
obtaining access to the bids of its rivals for each impression, which it could not see in header
bidding auctions. Thus, even when other ad exchanges opted to participate
in Open Bidding, they
initially did not have
access to the same data: they were
forced to share their bids with Google
without any reciprocity.
20
Although Open Bidding provided an additional avenue for rival ad
exchanges to participate and potentially to win inventory, those ad exchanges were forced to
cede control over the transaction to Google and take steps that diminished their overall
competitiveness. By contrast, alternative forms of server-side header bidding offered by market
participants without Google’s market power have much lower—or no—fees and do not include
the restrictions and limitations that Google incorporated into Open Bidding. Notwithstanding
these benefits, Google’s conduct has stunted adoption and growth. Thus, in the end, Open
Bidding fulfilled Google’s intent to counter header bidding in a manner that ultimately protected
Google’s publisher ad server monopoly, and in turn, Google’s ad exchange, AdX.
185. Despite Google’s success in using Open Bidding to blunt the impact of header
bidding, Google came to fear that a header bidding wrapper (code designed to run a multi-
exchange header bidding auction), such as Prebid or Amazon’s Transparent Ad Marketplace
(“TAM”), could one day supplant the publisher ad server as the ultimate decision-maker of
which ad to serve. Doing so would threaten the means by which Google had given its ad
exchange an unfair advantage over rival ad exchanges. If header bidding were ab le to aggregate
enough advertiser demand, Google believed publishers might be willing to risk adoption of a
20
Only recently has Google begun to share some bidding information with Open Bidding
participants—but not header bidding ad exchanges—in a form that has largely proven
unworkable.
81
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 86 of 153 PageID# 86
header-bidding-focused ad server, because of the diminished importance of
advertiser demand
exclusively
available through Google
Ads.
186.
In light of this fear, Google set out to lobby other unique sources of
advertising
demand (such
as Facebook)
or potential aggregators of advertising demand (such as
Amazon)
to
adopt Google’s Open Bidding rather than invest in header bidding infrastructure.
b)
Google Further
Stunts Header Bidding by
Working to
Bring
Facebook and Amazon
into
Its Open Bidding Fold
187.
Even before the rise of header
bidding, Google had identified Facebook as
a
potential competitive threat. Facebook had at one
point shown ambitions to challenge Google as
a full-stack ad tech competitor, acquiring a
publisher
ad server in 2013 and a video advertising
SSP in 2014, though both products were later shuttered. Years later, Facebook recognized that
any full-stack ad tech strategy “is subject to one bottleneck and intermediaryGoogle. They
‘own’ the Ad Server, and hence the last mile relationship with publishers.” Facebook further
observed that “[o]ther players in the market, such as Amazon, recognize that unseating G
oogle,
and its relationships with publishers is hard, and are also choosing to build on top of Google’s
rails.”
188.
Though it had abandoned its efforts to be a full-stack competitor, Facebook still
aimed to grow its advertising business beyond its
owned and operated (“O&O”) digital
properties (e.g., Facebook Blue and Instagram
apps), which were increasingly supply-
constrained. As the number of advertisers on these properties
grew, demand threatened to
outpace available inventory;
Facebook sought publisher inventory outside Facebook to satisfy
this unmet advertising demand.
In 2014, it launched Facebook Audience Network (“FAN),
which Facebook described as the “power of
Facebook ads, off-Facebook.”
FAN allowed
82
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 87 of 153 PageID# 87
Facebook advertisers to extend their campaigns outside of Facebook O&O
properties with a one-
click, opt-in button.
189.
At launch, FAN primarily
worked with mobile app advertisers to place ads in
other mobile apps in order to drive app installs and engagement. It later expanded to open web
on mobile devices. By 2016, FAN was participating in the
growing header
bidding movement,
partnering with header bidding wrappers to submit real-time, simultaneous
bids, and
eventually
launching
full-scale header bidding in 2017.
190.
As a large
ad network connected to millions of Facebook advertisers, FAN
also
competed with Google to lock up available publisher inventory for its advertisers. Prior to
joining Open Bidding, Facebook executives foresaw a status quo of “hand-to-hand combat”
between the
companies to secure
access to sufficient inventory
from publishers. Google feared
such competition with Facebook would end up “eat[ing]
margin,” and that
Google might
“respond identically” through de
als with top publishers, thus “driving a price war.”
Facebook
was equally leery of such a future, with one executive fretting that the “significant investment
required to lock up inventory through direct deals” with publishers would “[l]ikely start a
race to
the bottom on margin.”
191.
Google took note of FAN’s launch and kept a wary
eye on FAN
as it grew,
describing Facebook as “a unique competitive challenge
for us, both short-
and long-term”
because of its “strength in ad formats and targeting.” Google understood Facebook’s
reach with
over a billion users, and it understood that just as Google had valuable targeting and
demographic data from its O&O properties—including Search, Gmail, YouTube, Android, and
Play Store—Facebook, too, had a massive amount of valuable data
from its O&O properties.
Even though Facebook had largely
given up on building a direct competitor to Google’s
83
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 88 of 153 PageID# 88
publisher ad tech stack, Google saw looming “
[d]isintermediation [t]hreats” to DFP from
“[l]arge [n]etworks with unique data and advertiser scale seek[ing] direct inventory
access[,]
[g]oing direct to pubs or
using existing [third-party]
channels like Header
Bidding.” By
contrast,
Google characterized full-stack competitors as
“historical competition” of little concern: “This is
a short-term threat and we are well positioned here.
192.
As FAN began to test and use header bidding, Google
grew increasingly alarmed
at “the existential threat posed by
Header
Bidding and FAN.” Google strategized over how to
respond to FAN’s entry into header bidding, and in September 2016, Google laid out a plan to
bring F
AN into Google’s Open Bidding program.
Significantly, Google
concluded that bringing
FAN demand into Open Bidding w
as a better alternative to slow publisher
adoption of header
bidding than “[a]ggressively mak[ing] [Open Bidding] much better than [header bidding].”
193.
Rather than making a better product and competing on the merits, Google sought
a deal with Facebook to bring F
AN into Google’s Open Bidding—away from rival exchanges’
header bidding auctions—to
“dry
out” the nascent threat posed by header
bidding. If
competition
with Facebook was inevitable, it would be better for Google to compete on a field it still
controlled, with the many
advantages it had constructed for itself, thus protecting D
FP’s market
dominance. Indeed, Google
concluded that while
it “[c]annot avoid competing with FAN,” it
could, through a deal with Facebook, “build a moat around our demand.”
And as Google’s
product leadership would ultimately recommend to
CEO
Sundar Pichai, with a Google-Facebook
deal, “[f]or web inventory, we will move [FAN’s] demand off of header bidding set up and
further weaken the header bidding narrative in the
marketplace.”
Facebook, meanwhile, was
frank in its assessment of Google’s motivation for
the
deal: “What Google wants: To kill header
bidding (us baptizing [Open Bidding] will help significantly).”
84
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 89 of 153 PageID# 89
194.
Ultimately, in September 2018, after
a long negotiation and approvals by
each
company’s top brass—including Pichai, Mark Zuckerberg, and Sheryl SandbergGoogle and
Facebook entered into a
“Network Bidding Agreement” (“NBA”). The deal provided Facebook
with unique terms, including a
contractual promise of no last look and direct remittance to
publishers, ensuring that Facebook would continue to maintain its publisher-facing relationships.
In exchange, Facebook committed to a minimum
annual spend on Open Bidding and was
incentivized, through an all-units, tiered volume discount, to shift spend to Open Bidding and
away from possible alternative header bidding avenues.
195.
Having tried and failed to challenge Google as full-stack competitor—in part
because of Google’s anticompetitive conduct described above—Facebook ultimately resigned
itself to operating on top of Google’s rails. While the NBA satisfied Facebook’s need for
increased access to publisher inventory, Facebook recognized that it would also “reduce our
future optionality to build our own ad tech and the likelihood of a newbie like Amazon[, which
had introduced a header
bidding wrapper,] succeeding.”
Facebook believed that, while perhaps
“inevitable,” the deal would nevertheless “accelerate Google’s stranglehold on ad tech.”
Facebook’s then-VP of Partnerships opined that “by doing this deal, we
will cement [Google’s]
position of power.”
196.
Amazon’s TAM posed a
different
competitive threat to Google’s dominance. It
allowed publishers to solicit bids from multiple
ad
exchanges via a single call from a webpage to
Amazon’s extensive network of servers. And Amazon took only
a small one cent CPM fee—
much lower than Open Bidding’s 5% fee—for every transaction that flowed through TAM.
Google initially feared TAM could aggregate advertising demand in a way that challenged
Google’s ad exchange and publisher ad server, leading Google to ask Amazon what it would take
85
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 90 of 153 PageID# 90
for Amazon to stop investing in its
header bidding product. H
owever, Amazon rebuffed such
requests and continued to develop and deploy TAM. But as with other header bidding solutions,
TAM could not fully circumvent all of the restrictions and preferences baked into Google’s
ad
tech products, which website publishers still relied upon. For example, TAM remained subject to
a “last look” by Google’s ad exchange, allowing
Google’s
ad exchange
to win any impression
that would otherwise flow through TAM by
matching
the competing price from
TAM.
197.
Google’s
Open Bidding—and Google’s efforts to shift the focus of other
major ad
tech companies like
Facebook from header bidding toward Open Bidding—stunted header
bidding’s adoption, leaving header bidding unable to pose a
true threat to Google’s monopoly
power. In doing so, Open Bidding a
chieved its goal of blunting the
growth of header bidding a
nd
protecting Google’s
publisher
ad server. Today, Google still has its
publisher
ad server
monopoly. Header bidding persisted, but
its adoption stagnated. A

more surreptitious methods to restrain competition and “dry out”
ad exchanges using header
bidding.
c)
Google
Manipulates
Its Publisher Fees
Using Dynamic Revenue
Sharing in Order to Route
More Transactions Through Its Ad
Exchange
and Deny Scale to Rival Ad Exchanges Using Header
Bidding
198.
Emboldened by its success in manipulating advertiser fees under Project
Bernanke, Google implemented a similar program for the
ad
exchange fees it charged publishers.
The goal was the same: push more high-value transactions through the
Google
ad exchange
and
away from
rival ad
exchanges, including those
engaged in header bidding. Google did not simply
lower its publisher fees
across the board to compete aggressively on the
merits. Rather, Google
again
used
the competitive data it alone obtained
through its
publisher
ad server monopoly to
adjust its fees—and in turn its
ad
exchange’s bids—in a manner calculated to increase the
86
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 91 of 153 PageID# 91
number of competitive transactions won by Google’s ad exchange, while preserving Google’s
margins and increasing Google’s revenues and profits. In doing so, Google again was able to
cherry-pick the most valuable transactions out of the hands of rival ad exchanges, further
sabotaging their ability to build scale and compete effectively, all without compromising
Google’s rich bottom line because Google deftly made up the difference in its take rate on other,
less valuable, transactions.
Fig. 16
199. Google called this program sell-side dynamic revenue share. It altered the
standard 20% ad exchange fee (revenue share) charged to publishers (sell-side) on an
impression-by-impression basis (dynamic). At a high-level, the program doubled down on the
benefits Google afforded its ad exchange through dynamic allocation. With dynamic allocation,
Google’s ad exchange already had the ability to see and use the competing price of its
competitors before bidding, while rivals were forced to compete in the equivalent of a blind,
sealed-bid auction. Advertisers on Google’s ad exchange were able to observe the rival ad
exchange’s offer price and bid accordingly. Google’s ad exchange also used the rival ad
87
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 92 of 153 PageID# 92
exchange’s price as a floor,
only
charging the winning advertiser on Google’s ad exchange m
ore
when other advertisers
on the exchange also had higher bids.
200.
Dynamic revenue share created
an additional advantage for
Google’s ad
exchange: after Google’s ad exchange
ran its auction, Google
could adjust the winning bid up or
down—by
as much as 20%—to beat the price offered by
a rival ad exchange. This ensured
Google’s ad exchange
won even more transactions at a cost
equal to or
only
slightly above the
highest
bid of
Google’s ad exchange
rivals, recouping any discount of
ad
exchange fees
by
raising the fees it charged
on other less competitive transactions.
Only by
virtue of Google’s
control of the dominant publisher ad server and the advantages that ad server afforded Google’s
ad exchange, such as last look, could Google implement such an anticompetitive program.
201.
Since its
launch in 2009, Google’s AdX
ad
exchange has consistently
charged
nearly all publishers a 20% revenue share fee for
all “open auction” transactions—auctions not
limited to a small set of
buyers—on its ad exchange. This means that for transactions
on
Google’s
ad
exchange, Google could withhold 20% of what the
advertiser
buying tool paid
before passing the balance to the publisher
(on top of any fee Google
charges advertisers using
its advertiser
buying tools). Beginning in 2014, Google
changed the way it applied AdX’s
fee.
Instead of taking a 20% cut on every individual transaction, Google allowed its
take rate
to
fluctuate across transactions with the goal of
averaging a
20% fee for each publisher over the
course of the month, which continues today.
202.
Google implemented
the
sell-side dynamic revenue share
program
with
the
competitive data it was able to obtain through its
publisher
ad server monopoly. Through
dynamic allocation,
buyers on Google’s ad
exchange, including Google Ads,
were
able to see the
highest rival
bid before
competing. After running i
ts own internal auction, Google’s ad exchange
88
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 93 of 153 PageID# 93
compared its highest bid to the highest rival bid, which set the price
floor of the Google
ad
exchange auction. When comparing bids, Google
considered the
“net bid” to the
publisher, i.e.,
the amount the publisher
would receive after all
ad
exchange fees were deducted.
If
Google’s ad
exchange
would have lost a transaction because
Google’s
ad exchange
fee
brought its net bid
below the rival bid, Google
could adjust its fee for that impression to win the transaction.
Depending on the rival bid and the publisher at issue, Google could reduce
its
ad
exchange fee to
0%, essentially boosting
its
ad
exchange’s bid by
20%. If no rival ad
exchange’s bid was
competitive,
Google’s ad exchange
charged the
full 20% fee, or more.
203.
Because Google’s
publisher
ad server provided its
ad
exchange—and only its
ad
exchange—the ability to effectively open the sealed bids of its rivals before
bidding and adjust
its bid accordingly, only
Google’s ad exchange
could win more transactions this way without
substantial decreases in
margins. All other
ad
exchanges had to compete based either on static
average prices in the waterfall or bid for impressions via header bidding without any information
on competitors’ bids. Because of the way dynamic allocation operated, rival ad
exchanges
were
disincentivized from
lowering
their own ad
exchange
fees to boost their bids. If they did so, they
were not particularly more likely to win additional transactions. Instead, Google’s ad
exchange
could still swoop in afterwards and win the transaction by
matching the rival ad exchange’s bid.
By contrast,
Google could adjust its
ad
exchange fee (1) only when necessary
and (2) by the
exact amount
needed, given its privileged position in the
publisher
ad server
space.
204.
Google
later
went a step
further, allowing its revenue share fee to
go negative for
some transactions (i.e., s
ubsidizing its advertisers’ bids), as it had with Project Bernanke. Google
offset these subsidized transactions by charging more than a 20%
ad
exchange fee on
transactions where there
were no competitive bids from rivals.
89
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 94 of 153 PageID# 94
205. The program, which continues today, s ubstantially improved Google’s position
while further depriving other ad exchanges of scale. With the launch of the initial version of the
program, Google saw an increase of more than 11% in the number of transactions flowing
through its ad exchange, providing an additional $105 million in annual revenue to Google,
almost entirely at the expense of rival ad exchanges. The more aggressive version of the program
launched in 2016 resulted in an estimated increase of almost 5% in Google’s ad exchange profits
while reducing the amount of advertiser dollars that were ultimately paid to publishers.
206. Google did not allow publishers to make an informed choice about whether to
provide Google’s ad exchange with these advantages. Rather, Google pushed through sell-side
dynamic revenue share in the same way as many of its other programs: it imposed the changes
on publishers by default with virtually no transparency for publishers or advertisers into what
Google was doing. Even when one large publisher asked for an explanation, its Google client
representative declined to provide any details, indicating the change likely would have little to no
impact on the publisher.
207. Of course, Google did not disclose that the program further stacked the deck in
favor of Google’s ad exchange or that it was designed to further concentrate high-value
transactions on Google’s platforms at the expense of competition by rival ad exchanges.
d) Google Launches Project Poirot to Manipulate Its Advertisers’ Spend
to “Dry Outand Deny Scale to Rival Ad Exchanges That Use Header
Bidding
208. By the fall of 2016, Google worried that it needed to take additional steps to stem
the competitive threat from header bidding. As such, Google considered options “for mitigating
[the] growth of header bidding infrastructure.”
209. The first place Google turned was the substantial volume of advertiser spend that
flowed through its large advertiser demand side platform, Display and Video 360 (“DV360”). By
90
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 95 of 153 PageID# 95
2016-17, Google’s DV360 was already one of the
largest demand side platforms in the market
with a nearly 30% share
of gross digital advertising revenue
flowing through demand side
platforms. Google was
familiar with wielding the
power stemming
from the advertiser spend
locked into Google Ads, but it had previously allowed the larger, more sophisticated advertisers
and ad agencies
on DV360 greater control over where and how they bought advertising
inventory. As a result, these advertisers frequently transacted on rival ad
exchanges
that
provided
lower-cost or more valuable inventory. As of early
2017, more than half
of
total advertising
spend b
y
DV360 advertisers
flowed through rival ad
exchanges.
210.
Google became increasingly
concerned
that spend from
DV360
advertisers was
driving header bidding’s
growth and helping
rival ad
exchanges
compete. As
one of
Google’s
product management leaders for publisher
ad products
reported to his colleagues, “I think you
know this, but
I am told regularly that [DV360] is
the top buyer on every other
ad
exchange, so a
huge
chunk of publisher
HB [header bidding] revenue is Google demand going outside our
ecosystem
and then coming back via 3PE/HB [third-party ad
exchanges/header bidding].”
DV360 advertisers often represented the largest buyers
on rival ad
exchanges
engaged in header
bidding.
211.
If
header bidding was
left unchecked, Google feared its own advertisers’
spend
would continue to shift to rival
ad
exchanges
and thereby
allow
those
rival
ad exchanges
to gain
the scale and network
effects
needed to
become serious competitors. Google could not allow that
to happen.
212.
In October 2016,
Google employees responsible
for DV360 reached an “overall
consensus” that Google did not “want to compete
on [header bidding] queries.” To that end,
Google
engaged in a series of projects designed to reduce the flow of
DV360 advertiser spend to
91
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 96 of 153 PageID# 96
rival ad
exchanges
engaged in header bidding and redirect
that spend ba
ck to Google’s ad
exchange, regardless of the cost to publishers and advertisers. Hence, even though DV360 was
supposed to be a tool that enabled advertisers to bid most effectively for the inventory they
wanted, in Google’s hands, DV360 was weaponized to stifle competition. Not only was this
conduct
against the best interests of
Google’s own advertisers, it was
against the
best interests
of
DV360 itself because it harmed the very quality and profitability of the tool
Google
had created
and promoted t
o customers.
213.
As Google’s
Managing Director
for Global Publisher Solutions and Innovation
explained
in response to news that a competing ad exchange had lowered its fees, the
overarching goal
for Google
was
not for DV360 advertisers to benefit from reduced fees on other
exchanges but
for advertiser spend flowing through Google’s tools to “only buy on AdX
impressions that are [available both] through AdX and multiple”
ad
exchanges in order to “dry
out HB [header bidding]”
ad
exchanges.
Fig. 17
92
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 97 of 153 PageID# 97
214. Google’s initial proposed strategy was to go all insimply block DV360
advertisers from buying on rival ad exchanges any inventory offered by publishers Google
believed used header bidding. In late 2016, Google experimented with creating a “white list” of
publishers that did not use header bidding, retaliating against publishers that dared embrace
innovative technology that could improve publisher revenue. Google’s DV360 advertiser tool
would permit advertisers to submit bids on rival ad exchanges only for inventory from such
white-listed publishers; it refused to allow its advertisers to submit bids on rival ad exchanges if
Google suspected the relevant publisher used header bidding. The intended effect was obvious:
“move a lot of rev[enue] to AdX and put pressure on HB [header bidding] infra[structure].”
Unfortunately for Google, experiments testing such an extreme strategy showed that the
approach would not only harm advertisers and publishers but also Google. The experiments
predicted Google’s DV360 buying tool would lose approximately 30% of both impressions and
revenue.
215. At a meeting discussing the experiments’ results, however, a Google Product
Manager suggested an alternative solution to surgically target the threat of header bidding on
rival ad exchanges while minimizing losses to Google: “instead of stop bidding on HB [header
bidding] queries, we could bid lower on HB queries.” When combined with the various
advantages Google had afforded its ad exchange within Google’s publisher ad server, this
approach potentially could achieve all of Google’s goals: inhibit advertisers from transacting
through rival ad exchanges engaged in header bidding while allowing Google to redirect revenue
and transactions back to Google’s ad exchange, where it could charge supra-competitive fees.
93
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 98 of 153 PageID# 98
216.
Google’s product
and engineering teams quickly turned to implementing this plan
of attack under the code name Project Poirot.
21
The purpose of the project was straightforward:
Google would shift transactions away from ad exchanges using header bidding and to Google’s
AdX by artificially manipulating the bids sent to rival ad exchanges so that Google’s AdX could
win those transactions more often (even if that meant harming Google’s own advertisers). Or, as
Google put it: “for HB [header bidding] we should win back more on AdX.” By July 2017,
Google changed the settings of DV360 so that by default all advertising campaigns were opted
into Project Poirot; only 1% opted out.
217. Project Poirot worked by systematically lowering all DV360 bids to rival ad
exchanges that no longer employed second-price auctions—a proxy for identifying ad exchanges
using header bidding. For each ad exchange, Google set a percentage by which it reduced all
DV360 bids to that ad exchange. Initially, Google reduced advertiser bids by 10% to 40%; later
Google reduced bids for some ad exchanges by as much as 90%. Because Google’s AdX did not
participate in header bidding, none of DV360’s bids on Google’s ad exchange were decreased,
even where DV360 bid on the same impression on both a rival ad exchange and Google’s ad
exchange. T his manipulation of advertiser bids virtually ensured that Google’s ad exchange
would win the relevant auction by virtue of the deliberately decreased bids supplied to rival ad
exchanges for the same impression.
218. In important ways, the Project Poirot advertiser bid manipulation scheme was
both more insidious and more profitable for Google than Google’s initial proposal of not bidding
at all into rival ad exchanges using header bidding. First, by allowing its DV360 advertisers to

Project Poirot was named after Agatha Christie’s iconic master detective character, Hercule
Poirot. Project Poirot was designed to identify and respond effectively to ad exchanges that had

bid on all inventory on rival
exchanges, albeit at substantially lower
levels
that won fewer
transactions, advertisers
could still buy
the limited set of
inventory that
publishers chose not to
make available at all to
Google’s ad exchange, as well as inventory that only appeared
particularly valuable in light of targeting data
available through a rival
ad exchange. However,
reduced bids designed to win fewer transactions
went against the interests of DV360 advertisers
and DV360 itself as
a platform. Both would have
benefited from winning m
ore inventory on
rival ad exchanges
at prices advertisers were willing to pay, but for Google
surreptitiously
lowering their bids.
219.
Second, for inventory available to DV360 on both a
rival ad exchange
and
Google’s ad exchange, Poirot and dynamic allocation worked together to ensure that
Google’s ad
exchange
often won the transaction. To do this, Google used its control over the bids of
advertisers using its DV360 product. While these large, sophisticated advertisers set general
parameters for bidding, especially
after the launch of Poirot, Google
alone
determined the
particular bid made on behalf of the advertiser on each of the millions or billions of pieces of
inventory
an advertiser bid on within
each ad exchange; Google opted advertisers
into the
program while affording t
hem
no meaningful visibility into this level of bidding. Through
Project Poirot, Google used this power to lower
DV360 advertisers’ bids on rival ad
exchanges,
and in turn, that ad exchange’s
winning bid. Through dynamic
allocation, the winning bid on the
rival ad exchange—now
lowered by Poirot—served as the price floor for
Google’s ad exchange
auction. DV360 could then win the same impression on Google’s ad exchange
by matching that
price. Working together,
Poirot and dynamic
allocation has
led to reduced price competition for
Google’s ad exchange
and
has
ensured that more transactions flow to Google’s ad exchange,
even if Google
charges
higher
ad
exchange fees.
Google
has only
been
able to implement this

Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 100 of 153 PageID# 100
scheme by virtue of its control throughout the ad tech stack: advertisers and ad agencies using
DV360, the AdX ad exchange, and the publisher ad server.
220.
A hypothetical illustrates Project Poirot in action. An advertiser
using DV360
might configure an ad campaign to pay
a maximum price (for example, $1 CPM) for a particular
type of
advertising impression. Under Poirot, G
oogle would lower that maximum bid when
bidding on rival ad exchanges that used header bidding by applying an ad exchange-level
multiplier, for example, bidding $0.38, $0.42, and $0.40 on three rival
ad exchanges. In this
example, the $0.42 bid is the highest and wins the
header bidding auction; that bid is then passed
to the publisher’s ad server after the ad
exchange deducts its revenue share fee (assumed here to
be 15%, r
educing the net
bid to $0.36). Next, the ad server sends that price
along with a
request
for a bid to Google’s
ad exchange via dynamic allocation. The $0.36 serves as a price
floor and
is shared with bidders on the ad exchange. On behalf of the
same advertiser
as before, DV360
now bids the advertiser’s maximum bid ($1) and wins the impression. Because Google’s
ad
exchange ran
a second-price auction, however, the publisher receives only the floor price, $0.36.
Google charges the advertiser this price plus the applicable ad exchange revenue share (20%),
which translates to $0.45.
22
Ultimately, this means the advertiser pays more for the impression
than it would have paid bidding via a rival ad exchange, Google is able to profit by extracting its
revenue share fee at the ad exchange level, and the rival ad exchange that otherwise would have
won (because it would have charged a smaller revenue share fee than Google’s ad exchange
from the same DV360 bid) is denied the transaction.
22
Google also charges an additional fee for use of its DV360 service (on average 9%), which is
the same regardless of the ad exchange where the inventory is purchased.
96
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 101 of 153 PageID# 101
221. Google’s prelaunch experiments found that Project Poirot would reduce publisher
display revenue
from DV360 by over 10%. By contrast, the predicted “surplus”—additional
revenue shared between
Google and advertiserswas only
about 1%. The total number of
impressions DV360 purchased would drop by almost 5%.
In particular,
Google recognized that
some advertisers
would no longer
be able to buy
certain impressions only offered on rival ad
exchanges, because
even
if those advertisers
were
willing to pay the
minimum
price set by the
publisher, Poirot reduced their bids below the minimum. Poirot prevented these advertisers from
spending their
full advertising budgets and resulted in some ad inventory
going unfilled—a loss
for the display advertising market as a
whole.
222.
Project
Poirot formally launched in July 2017 under the name
“Optimized Fixed
CPM Bidding.” Google did not afford its advertisers a meaningful opportunity to choose
whether
Google
could systematically lower their bids on
rival ad
exchanges. Instead, Google imposed
these changes while providing virtually no information to its advertisers on the nature or
extent
of the program. Over 99% of advertising campaigns were
subject to Poirot: all “automated
bidding” campaigns on DV360 incorporated Poirot automatically, and Google opted in by
default all “fixed CPM bidding”
campaigns.
223.
Internally, Google sometimes justified Poirot as benefiting a
dvertisers, but such
justifications were pretextual. Google designed Poirot to lower DV360’s bids into third-party ad
exchanges ostensibly to account for
“non-second-price auctions,” such as where a publisher uses
soft floors that are set above the second-highest bid or uses floors that change based on bidding
history. But
Poirot did not apply the same rules to Google’s ad exchange that
it applied to its
competitors.
Poirot
did n
ot adjust DV360’s bids into AdX even though AdX
was
not a true
second-price auction: AdX
itself used
features such as Reserve Price Optimization (“RPO”)
97
that—like those used in purported non-second-price auctions—similarly adjusted floors based on
what bids Google expected to receive. As one document explained, RPO went live in 2015
(before Poirot) and “move[d] Google away from a 2nd price auction.” Google employees
discussed the interaction between RPO and Poirot and noted that RPO was designed to go
undetected by Poirot, and they concluded that if AdX continued to develop more aggressive
versions of RPO then DV360 would adjust Poirot to avoid detecting this auction dynamic within
AdX. Poirot intentionally did not target all non-second-price auctions; it gave the auctions
Google conducted a pass.
224. As Google’s Director of Product Management for Display and Video Ads noted,
Poirot’s initial implementation in 2017 was “quite effective, resulting in [DV360] spending 7%
more on AdX and reducing spend on most other ad exchanges.” One employee on Google’s team
explained that with Poirot, “spend on 3PEs [third-party ad exchanges] dropped by a whopping
32%.” Poirot shifted approximately $200 million of DV360 advertiser spend away from rival ad
exchanges and toward Google’s. This spend was subjected to Google’s 20% ad exchange
revenue share fee—one of the highest in the industry—resulting in an additional $40 million in
profit for Google.
225. This substantial shift in advertising spend by the largest demand side platform in
the market, combined with the systematic drop in bid price, had real consequences for
competition between ad exchanges. DV360’s lowered bids reduced the competitiveness of
header bidding auctions, which in turn lowered the win rates of ad exchanges relying on header
bidding. The win rate on Google’s ad exchange increased even though Google had made no
improvements to its ad exchange, offered no additional benefits to publishers, and reduced
advertisers’ reach (without their knowledge). Because publishers consider win rates before
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 102 of 153 PageID# 102
98
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 103 of 153 PageID# 103
investing the time and resources necessary to integrate with
ad
exchanges, Poirot’s hit to rival ad
exchanges made it
even
less likely publishers would continue to offer inventory
to these ad
exchanges
and less likely that new publishers would integrate
with these ad exchanges through
header bidding.
226.
Google’s success with Poirot was possible because of
Google’s
ability to control
the auction process run by
its monopoly
publisher
ad server
and
Google’s last-look advantage
stemming from its ad server’s dynamic
allocation function. Google was
able to lower DV360’s
bids into rival ad
exchanges
without fear of losing impressions—even if
DV360’s
reduced bid
lost in the
rival ad exchange’s
auctionbecause
for the majority of impressions, it
would get
another bite at the
apple
when Google’s
ad exchange
was later called
for a bid. And because
Poirot generally reduced
the clearing price of
header
bidding auctions, Google’s
ad exchange
could win the impression at a lower price, thereby
decreasing the revenues
ultimately paid to
publishers. Without
the
systemic advantages that Google’s publisher
ad server forced publishers
to afford
to Google’s ad exchange, and without Google’s dominant position among a
dvertiser
buying tools, Poirot could not have been nearly
as successful in halting the
potential rise of
rival
ad
exchanges.
227.
Seeing
Poirot’s initial success, Google doubled d
own on the
strategy. Google was
unconcerned about any potential blowback f
rom publishers (who had no meaningful alternative
to DFP) or advertisers (who had no insight into the changes). In September
2018, Google
launched “Poirot 2.0.” Under this new version of the program, Google reduced DV360 advertiser
bids
further,
by as much as 90% to some
ad
exchanges.
228.
Google’s prelaunch experiments indicated that Poirot 2.0 would significantly
affect
rival ad
exchanges, even more than the initial iteration. Google
anticipated Poirot 2.0
99
would further decrease
DV360 advertiser spend on rival ad
exchanges by
another 20%, lower
publisher payouts from auctions DV360 won by 20%, and lower
rival ad
exchanges’
win rates by
10%. The estimated impact of Poirot 2.0 on the most vocal proponents of header bidding
technology
was even more pronounced: AppNexus/Xandr would lose 31%
of DV360 advertiser
spend, Rubicon would lose 22%, OpenX
would lose 42%, and Pubmatic would lose 26%. For
Google’s ad exchange, on the other hand, Poirot increased revenue, publisher payouts, and win
rates, t
hrough a sleight
of hand forcing
a shift in advertiser spend. As
Google’s
Director
of
Engineering—and
chief
architect of Poirot—explained to colleagues, Poirot had largely
achieved
in practice Google’s earlier plan to boycott header
bidding auctions: “lowering bids may have a
similar effect” to stopping all bidding on
rival ad
exchanges. Poirot 2.0 also accomplished
Google’s strategic
goal to
“dry out” header bidding without the need for Google to take the
significant hit to its revenues and profits
that initial experiments suggested
might be necessary.
229.
Rival ad
exchanges lost significant
transaction volume
from Poirot, undercutting
efforts to
gain scale.
Immediately
after the launch, OpenX experienced a 30%
year-over-year
decline in DV360 advertiser spend, and Google internally identified Poirot as the “biggest
culprit.” As a result of the loss, OpenX was
forced to lay off approximately
100 employees.
Other
ad
exchanges also felt significant drops in DV360 spend and complained to Google.
Google’s internal discussions confirmed that Poirot 2.0 was the cause.
230.
Poirot’s success enabled
Google to maintain the 20% revenue share fee it
has
charged on its
ad
exchange
since 2009. Before Poirot, Google
employees
believed
such a high
fee was no longer sustainable,
as
header bidding risked commoditizing
ad
exchange services; if
header bidding continued, Google’s employees
expected the fee to drop to 5%. By 2019, after
Poirot 2.0 was fully implemented, Google’s
Americas
Partnership Finance Lead
noted that on

Google’s ad exchange fee, “we should continue to hold the line, esp. given currently healthy
growth levels, since project Poirot.” Poirot, which continues in some form today, s hifted spend to
Google’s ad exchange with its higher revenue share fee; deprived competing ad exchanges of
scale, auction pressure, and higher win rates; lowered publisher payouts; and limited advertisers’
ability to fully and effectively spend their budgets—all without any improvements to Google’s
own ad exchange.
e) Google Imposes So-Called Unified Pricing Rules to Deprive
Publishers of Control and Force More Transactions Through
Google’s Ad Exchange
231. Poirot was incredibly effective at redirecting DV360 advertiser spend away from
rival ad exchanges, and putting Google’s ad exchange back on the road t o acquiring monopoly
power, not withstanding the opening that header bidding had briefly created for competition
between ad exchanges. The fraction of DV360 spend on AdX increased from approximately 40%
to 70% due to Project Poirot. An internal Google document fretted that “Adx is now dominant to
the point where we need to communicate to advertisers (and sometimes even to ad exchanges)
why over 70% of [DV360] spend happens on Adx.”
232. But Google was not satisfied. Despite the dramatic shift of DV360 spend to AdX
and away from rival ad exchanges, Poirot was not quite as effective as they thought it should be,
given how much Google had stacked the deck in favor of its ad exchange. One Google
Engineering Director noted that while Poirot had made progress on shifting spend to Google’s ad
exchange and away from rival ad exchanges, “we need to do more.” A review of publisher data
from Google’s ad server and Open Bidding—information effectively covering the sale of nearly
all open web ad inventory—quickly identified the problem: Google’s publisher customers.
Google employees realized that publishers were using pricing controls built into the publisher ad
server to set the terms on which their inventory was sold to advertisers, including by setting
101
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 106 of 153 PageID# 106
different minimum price
floors for different buyers. Google perceived publishers’ ability to steer
ad sales to rival ad
exchanges,
and
to control who bought their ads
and at what price, as
a threat
to Google’s
ability to control the flow of transactions.
233.
Within Google’s
publisher
ad server, publishers
were
able to set different
price
floors for specific
exchanges or advertiser buying tools. For example, a publisher could set a
price floor of $2 for Google’s
ad exchange
and $1.80
for the
competing ad
exchange,
OpenX. If
OpenX submitted a winning bid of $1.85, and Google’s
ad exchange
had a buyer willing to pay
$1.90, the inventory
would still be sold to the OpenX advertiser
because Google’s
AdX
ad
exchange failed to clear the minimum price set by
the publisher for AdX.
234.
There
are many
reasons why publishers might want to set non-uniform price
floors for different
exchanges or advertiser buying tools. Publishers have relationships and deals
with advertisers, agencies, and ad
exchanges that
have implications beyond the sale o
f a single
impression. For example, a publisher might want to boost an ad
exchange’s chances of winning a
particular impression
in order to reach previously negotiated volume discount thresholds.
Additionally, some publishers might set a higher
price floor for Google’s ad exchange
than for a
rival ad exchange to
account for publisher-specific preferences for
a particular
ad
exchange, the
quality of advertiser demand, better
advertisement load
rates, and data advantages.
Some
publishers also wanted to mitigate risk from overexposure to a single
exchange
(such as
Google’s ad exchange) or to avoid conflict with direct sales
channels.
For all of these reasons
and others, the ability to set different floors for different
ad
exchanges or
advertiser buying tools
was an important tool that publishers used to manage these partner relationships and direct the
sale of their own inventory to maximize their overall business objectives.
102
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 107 of 153 PageID# 107
235.
Google
recognized that the ability to choose
different floors for different ad
exchanges or buying tools was a DFP feature that
publishers valued. One
Google
Senior Product
Manager
explained to his colleagues:
“The general idea is that the pub[lisher]
doesn’t care
about
maximizing revenue on every individual query
they
want to maximize
revenue for their overall
business, and that might
mean sacrificing a few pennies of lost indirect revenue” on a single
transaction. Similarly, Google’s
Director of Global Partnership and Publisher Solutions
explained:
“Pub[lishers]
are also rational[] when they decide to diversify their source of
revenues” using floors
given that
“[i]t help[s]
them to keep Google at bay
and put pressure on us
(similar to any industry).”
By using different price floors, publishers
expressed a willingness
to
occasionally
accept a slightly lower price from a
rival ad exchange
than from
Google’s ad
exchange
for the same inventory.
But publisher
controls and goals mattered little when they
conflicted with Google’s
desire for increased market share and profits.
Google refused to tolerate
a system in which
publishers exercised control over their own inventory.
236.
Even before Poirot, Google had noticed that some publishers used price
floors to
direct the flow of
certain transactions to rivals. In response, G
oogle had insisted on “equal
footing”
clauses in certain publisher
contracts, which
ostensibly
prevented publishers from
offering inventory to competitors
on more favorable terms or at lower prices than those offered
to
AdX.
However,
these
contractual provisions were difficult to monitor and enforce even for the
small number of publishers for which they
applied. C
onfronted with a broader concern about the
operation of price floors in the wake of Poirot, Google developed an alternative approach that
was blunt but effective:
Google
simply removed the existing feature in its publisher ad server
that allowed publishers to set different floor prices and preference rival ad exchanges or buying
103
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 108 of 153 PageID# 108
tools. Going forward, only Google, not its customers, would be permitted to dictate preferences,
and only those preferences that advanced Google’s strategic ambitions would be tolerated.
Fig. 18
237. Recognition of the flooring “problem” was widespread within Google’s display
advertising leadership. When one Google employee asked why DV360 was still winning
inventory through rival ad exchanges, Google’s Project Poirot architect explained that “the best
guess is that the AdX [price] floors are higher.” He went on to note that “[t]his is one big
problem for the Adx team to try fixing so that more of the [DV360] buying will switch to Adx.”
He suggested that “if we figure out how to equalize floors (i.e., get the Adx floors down), as a
buyer, we will start seeing benefits in terms of buying more through Adx and decreasing
incrementality on 3PE” (third-party ad exchanges). As usual, Google did not care what was best
for its customers; Google insisted on doing whatever was necessary to decrease spend on AdX’s
competitors, thereby denying them the scale and competitive position to threaten Google’s AdX
monopoly.
104
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 109 of 153 PageID# 109
238.
Google’s internal analyses
of the pricing floor practice
demonstrated the
extent of
the “problem.” Google
believed its
AdX ad
exchange was
already
winning 66%
of
auctions
where an ad exchange used header bidding, but
for a little less than half
of
the inventory it did
not win, Google’s AdX had a higher bid than the
rival ad exchange that did win.
The AdX ad
exchange was losing these auctions because publishers had configured price floors that awarded
the inventory to a
rival ad exchange or rival demand source at lower per-impression prices than
AdX and/or Google
Ads offered in certain auctions. In response, Google went to work to block
publishers from setting price floors
that disadvantaged its AdX business.
Fig. 19
239. In March 2019, Google announced a number of changes to its publisher ad server
and ad exchange. Among the notable changes were the removal of granular publisher price
controls from the ad server. In their place, Google required publishers to set a single floor price
for inventory that applied to all ad exchanges and advertiser buying tools. Google called these
105
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 110 of 153 PageID# 110
degraded pricing controls Unified Pricing Rules, or UPR. Unified Pricing Rules were the
culmination of Google’s
work to stop publishers from using ad exchange-specific or buyer-
specific price floors to steer transactions to rival ad exchanges and away from Google’s ad
exchange and buying tools. Under Unified Pricing Rules, publishers were no longer
allowed to
set different price
floors for Google’s ad exchange
or advertiser buying tools versus other ad
exchanges or advertiser buying tools.
240.
Google
recognized this product change came with a number of
“major risks,”
including “(1) revenue drop for some pub[lishers]
23
(2) negative pub[lisher] reaction (loss in
ability to set per-buyer floors) (3) negative adv[ertiser] reaction (potential for DV3[60] spend
share ↑ on AdX).” Internal experiments found that UPR increased DV360 and Google Ads’
spend on AdX and decreased spend on rival ad exchanges. One analysis found that UPR caused
DV360 to win approximately 32% more impressions on AdX and led to a 6% increase in AdX
revenue.
241. Google bundled its imposition of Unified Pricing R ules with other changes to
provide cover. As one employee explained, Google “bundled . . . a bunch of contentious
changes,” such as the “overhauled pricing rules,” with less objectionable changes “to make the
contentious ones more stomachable.” For example, Google changed its ad exchange from a
second-price auction to a first-price auction, which altered some of the ways price floors
impacted auctions. Google used the auction format change to contend that the only legitimate
reason for differential price floors in its viewto increase the clearing price of a second-price
auction—had been eliminated. Google also claimed that the granular price control feature of its
23
Some publishers were able to achieve greater total revenue by flooring different ad exchanges
and demand sources at different prices.
106
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 111 of 153 PageID# 111
ad server only
confused its publisher base—even the sophisticated publishers most likely to use
price floors. Google
asserted
that it was doing those customers a
favor by
eliminating the
function.
242.
In
reality, Google’s internal documents demonstrate that these were pretextual
justifications for the true
driver of Unified Pricing R
ules: preventing publishers from
preferencing
rival ad exchanges.
Google employees candidly acknowledged that the change in
auction format alone “would have achieved most of what we desperately need to fix our
ecosystem,” irrespective of changes to price floors. But the Google ad
exchange “team wanted to
use this migration [to a first-price
auction] as an opportunity to significantly
limit the ability of
publishers to set floor-prices per buyers (which is a good goal to have).”
Externally, Google told
publishers and others that the combined changes would “simplify programmatic buying,”
“reduce complexity and
create a fair and transparent market for
everyone.” Internally, Google
acknowledged that
getting rid of higher price floors for Google’s
ad exchange was the “primary
internal objective for the
entire launch” of bundled changes and its “key driver.”
Internal Google
documents explained that the changes
“will be a shift in DV360 spend patterns away from [third-
party
ad exchanges].” Not surprisingly, internal Google documents identified the “winner” of the
new rules to be AdX, its own ad exchange,
and accurately listed rival ad
exchanges to be the
“losers” under the new rules.
243.
Publishers were livid when Google announced the change. At
an April 18, 2019
meeting with Google, publisher customers lashed out. Google’s meeting notes reflect that
publishers reiterated what Google
already knew: “optimizing
yield is important but CONTROL
is also important.” Publishers “laugh[ed]” when Google
employees tried to push the farce that
“we [Google] don’t want to take control away” from publishers. Publishers informed Google that
107
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 112 of 153 PageID# 112
“we can give
you 1,000 reasons why we
want buyer rules”
and pointed out
that “maybe flooring
doesn’t have to do with ‘pure
yield’ but might be
needed for ‘business reasons.’”
Notwithstanding the clear value the pricing r
ules
provided publishers, Google’s own desire to
prevent
publishers and rival ad
exchanges from circumventing the effects of Poirot won the day.
Google
refused to make
any
changes to the proposed Unified Pricing Rules.
Because it had a
publisher ad server monopoly, Google did not need to be responsive to its publisher customers’
needs; Google was confident that there was nowhere else for them to turn.
244.
By 2019, effectively
all viable
publisher
ad server
competitors had exited or were
in the process of
exiting the market. Even if an alternative publisher
ad server had remained, it
could not have provided publishers access to the substantial and unique Google Ads’
advertiser
demand that remained
available
almost exclusively
through Google’s
ad exchange.
245.
With Unified Pricing Rules, Google exercised its
market power to intentionally
degrade the quality of its publisher ad server at the expense of publisher customers. It did so to
prevent publishers from choosing to transact more through rival ad exchanges, further inhibiting
the ability of these smaller ad exchanges to gain needed scale and
compete effectively. Google
reduced the share of other ad exchanges not by making its own ad exchange more attractive to
publishers but, rather, by
preventing publishers
from preferencing other ad
exchanges and by
refusing to allow rival ad exchanges to compete for transactions on any dimension other than
per-impression price. At the same time, Google shifted those transactions to its own ad
exchange, further boosting Google’s profits derived from its supra-competitive revenue share
fees, at the
expense of both advertisers and publishers. Likewise, publishers could no longer set
lower price floors for particular demand source partners, such as non-Google advertiser
ad
networks, which reduced the possibility that publishers could partner with a rival to challenge
108
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 113 of 153 PageID# 113
Google
Ads’ dominance. Publishers were—and today still are—powerless to respond given the
lack of viable substitutes
to Google’s publisher ad server monopoly. They
are locked into
Google’s publisher ad server and subject to Google’s dictates about how they should monetize
their own inventory.
246.
Google
fully
launched Unified Pricing Rules in September 2019. As expected,
UPR
succeeded in shifting transactions away from rivals and to Google’s ad exchange. The
market share of
Google’s ad exchange
increased by
approximately 6% in 2019 following the
announcement
and ramp-up period. Google’s
advertiser business also benefited: the
average
floor price
faced by Google Ads’
advertisers on Google’s
ad exchange
dropped from a little over
$3 to about $1. Of course, had Google Ads bid for
inventory through ad
exchanges other than
AdX, Google Ads
advertisers
might
never
have faced the higher floors
applicable to
Google’s
ad exchange
in the first place.
They
would have
faced the floors that publishers chose to apply to
rival ad exchanges. Google’s internal modeling found that the Unified Pricing Rules created the
“primary benefit” of
Google’s bundled auction changes, and the
“best
guess” of the impact was
an annual increase of $430 million in Google’s gross revenues
and $118 million in Google’s net
revenues.
247.
Most importantly
for Google’s overall strategy, Unified Pricing Rules had a
“negative
effect on 3P SSP [ad exchange] spend.” For
example, one ad exchange competitor
complained to Google that its win rate had decreased 6% during the launch of Unified Pricing
Rules. Internally, Google employees attributed the decrease to Unified Pricing Rules and warned
others not to share this “extremely sensitive” information externally.
By the end of 2019,
Google’s ad exchange
was “still retaining
[the] largest and growing share
of spend” for inventory
sold via open auction.

Google Outright Blocks the Use
of Standard Header Bidding on
Accelerated Mobile Pages
248. Project Poirot and the imposition of Unified Pricing Rules are both examples of
Google wielding its power on both sides of the ad tech stack to stymie competition in the middle
for ad exchanges. Google could not directly block publishers from adding header bidding code to
their own webpages, so it had to resort to these indirect methods of limiting t he growth of header
bidding. But when given the opportunity to do just that—outright block adoption of client-side
header bidding—in one corner of the internet, Google leaped at the opportunity, consistent with
its broader strategy to stop header bidding in its tracks and thereby stifle competition from rival
ad exchanges.
249. Beginning in 2017, Google recognized it could use its monopoly power in the
general search marketspecifically its ability to rank websites that appear in search results—to
force at least certain publishers to forgo traditional, client-side header bidding and instead adopt
Google’s more limited and self-serving version it named Real Time Config (“RTC”). T o do so,
Google launched a project known as Accelerated Mobile Pages (“AMP”) in an effort to push
parts of the open web into a Google-controlled walled garden, one where Google could dictate
more directly how digital advertising space could be sold.
250. A year earlier, in 2016, Google began to prioritize within its Google Search
results websites that implemented an alternative webpage format known as AMP, which
purported to allow faster loading times and a better mobile web experience. It also conditioned
access to the News Carousel—the ribbon at the top of certain Google Search pages that
highlights relevant news stories—on the adoption of AMP. Technically, AMP was an open-
source project; in reality, Google and its engineers tightly controlled the AMP project through at
least late 2020; its engineers still have an outsized influence in the project today.
110
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 115 of 153 PageID# 115
251.
Although AMP’s faster loading a
nd improved user experience
goals appeared
altruistic,
Google
also recognized that its control
over AMP opened the door to advancing
Google’s financial interests, including its desire to
quell
the rising tide of header bidding.
Google’s Vice President
of Product for Mobile App Advertising drafted a proposal for “wall[ing]
off AMP” with “All-in-one Monetization, fully Google
controlled and branded: All
‘monetization’ of content build on these technologies goes through Google.” The proposal
explained:
“Given AMP is open-source, we propose the walled garden to include pages cached
and served by
Google”
and to “[u]se the power of Google Search to prioritize traffic built on
these technologies. ‘Point our biggest most important pipe there.’”
252.
For the first 18 months of AMP’s existence, the AMP standard fully supported
header
bidding, luring in publishers vying to appear at the top of Google’s
Search listings or in
the News Carousel. Early on, Google’s AMP Ads
Steering Committee formally considered and
decided not to deprecate
the mechanism for traditional header bidding in AMP because doing so
would hurt publishers’ ability to sell their advertisements.
Instead, the
committee agreed in
March 2017 that “[i]f a [publisher] implemented such a thing [header bidding], AMP has very
little influence from a policy perspective and business perspective -
even if
we, as Google, don’t
like it from a business perspective. AMP will look at it from an engineering standpoint and if it
meets the standards,
accept it.”
253.
However, just a few months later, Google abruptly changed course, overriding
the
view of the committee and shifting the open AMP
framework into a Google-controlled closed
environment where Google decided how digital advertising could be sold. Only a
Google-
dictated and Google-driven version of
“header bidding” would be allowed:
one
that provided
Google’s ad exchange a
preferred position and restricted publishers’ ability
to connect with their
111
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 116 of 153 PageID# 116
preferred ad exchange partners. Publishers could not use traditional header
bidding (i.e.,
client-
side header bidding) that could provide higher quality
advertising matches
and additional
revenue, and could only
call directly a limited number of ad exchanges and data providers.
Google
formally launched its version of header bidding for
AMP pages, RTC, i
n August 2017.
254.
While Google told the world
that its removal of traditional header bidding
was
based on page latency
and a desire to improve user experience, its internal documents painted a
different picture. Several
Google
employees shared their views that any concerns about user
experience or latency were a smokescreen
to mask Google’s real motivation: further propping up
its ad tech
monopoly
and profits. As a key software engineer explained, “If
DFP wants to say
‘We refuse to serve
an ad onto your AMP page if
we’ve been intermediated [by header
bidding]’, then we can certainly choose to do so. But that’s a DFP business
decision, not an AMP
platform one.” He added, “You product folks
are
welcome to make
whatever decision you want
about header bidding. But on the justification front, . . . your 500ms-delay-is-bad explanation
really doesn’t hold water.” He went on to say:
“If
publishers can make more money on AMP
pages via something that
causes ads to load a little later, but that doesn’t harm the [user
experience] of the non-ad portion of the page, I think the AMP ecosystem should absolutely
support it. I acknowledge that incentives here might not align, and I
am indeed saying that AMP
should embrace proposals that give more money to publishers even if it results in less money
for
DRX [DFP and AdX].”
Similarly, Google’s Vice President for News wrote, “AMP is under
pressure to increase revenue and, specifically, to effectively support dynamic bidding. We need a
solution. Also, please be cognizant of criticism that our reluctance on header bidding is driven by
business self interest, not principle.”
112
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 117 of 153 PageID# 117
255. AMP adoption ultimately proved to be relatively limited, especially outside of
news websites. As part of Google’s grand strategy to combat the growth of header bidding,
however, it served as yet another mechanism to deter publishers from adopting the technology. It
was a new tool in Google’s toolbox to use its monopoly power in adjacent markets to prop up
and protect its growing ad tech monopolies. It also demonstrated that Google was more than
willing to make misleading claims about performance as a pretext for stifling competition.
g) Google Replaces Its Last Look Preference from Dynamic Allocation
with an Algorithmic Advantage and Degrades Data Available to
Publishers
256. The shift of transactions from rival ad exchanges to Google’s ad exchange as part
of Unified Pricing Rules came at the same time that Google relinquished one of the substantial
preferences it had previously given its ad exchange: the “last look” advantage of dynamic
allocation. Its reason for doing so was not altruistic. Maintaining last look would have given
publishers a path to effectively floor AdX higher than other ad exchanges notwithstanding
Unified Pricing Rules. And as with the shift to a first-price auction, Google believed that
removing last look “allows bundling of other valuable changes, that can be positioned as pro-
competitive.” Google Engineering Director explained that Google “paired this change [dropping
last look] with other benefits to Google (fair access and uniform reserve prices), rather than
being forced by regulators to remove last look under disadvantageous terms.”
257. But even this concession was a mirage. Although eliminating “last look” might
have resulted in a small decline in transactions on Google’s ad exchangepartially offset by the
benefits of Unified Pricing RulesGoogle deployed a replacement that was effective in
replicating the prior advantage. Relying on its massive trove of data from its monopoly publisher
ad server and dominant ad exchange, Google developed an algorithmic model to predict the bids
of rivals for each impression. In this way, Google could still predictively “peek” at its rivals’ bids
113
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 118 of 153 PageID# 118
before submitting its own. Specifically, Google’s unique access via dynamic allocation to years
of data on multiple bids per auction for trillions of auctions allowed Google to estimate the
distribution of predicted prices necessary to replicate “last look.” Google’s technical documents
explain that for accurate predictions “[w]e need to predict the full distribution of competition, not
just the point estimate.” Only Google had the data to do so by virtue of its dominant position
across the ad tech stack. Moreover, the effects of years of a last look advantage did not disappear
overnight. Google had already obtained the benefits of preferential access and continued to
realize the enduring flywheel effects of scaling its ad exchange while eclipsing rivals.
Fig. 20
258. Google delayed giving up last look for months while it fine-tuned the “Smart
Bidding” algorithm that would replace it. When Smart Bidding launched, it fully offset the 30%
drop in Google Ads’ revenue that Google expected from the loss of last look (without Smart
Bidding) and turned an expected 10% drop in DV360 revenue into a revenue increase of 3%.
259. Beginning in late 2019, Google made some of the data used in Smart Bidding
available to rival ad exchanges, but important limitations applied. Google only shares data with
114
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 119 of 153 PageID# 119
rival ad exchanges that bid on the impression via Open Bidding (not header bidding); data is
limited
to the winning price for
an auction (where
the rival ad exchange lost) or the second-
highest bid (where the rival ad exchange won); and data is shared in a format that many
ad
exchanges
could not
use. This is insufficient for rival ad exchanges to replicate the broader data
trove to which Google has access
and against which it was able to train its bidding algorithms for
years. For their part, publishers have no ability to block Google from continuing to have
access
to this pricing data or to
allow rival ad exchanges
access to similar data outside the parameters
dictated by Google.
260.
At the same time
that it rolled out Smart Bidding, Google degraded the data it
made available to publishers that previously allowed them to monitor how Google’s ad exchange
was competing against rival ad exchanges. Prior to late 2019, Google made available to
publishers a “data transfer file” that allowed eligible publishers to see on an impression-by-
impression basis the individual bids from competition among ad exchanges and certain
advertising demand sources for the publishers’ inventory. Publishers
could then respond to
changes in the nature of
competition by tweaking t
he way in which they made their inventory
available to their ad tech
partners. Commenting on the earlier version of the data transfer files,
Google acknowledged their value was
to create a more transparent
auction marketplace
and
“enabl[e] publishers to find opportunities for incremental revenue.”
261.
Following the shift to Unified Pricing Rules and the introduction of Smart
Bidding, Google altered the files to prevent publishers from linking the bids from Google’s
advertising products to those from rivals using header bidding f
or the same
impression. This has
made it more difficult for publishers to make informed choices about how
and where to make
115
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 120 of 153 PageID# 120
inventory
available
and to monitor Google’s bidding behavior for potential anticompetitive
conduct.
V.
ANTICOMPETITIVE EFFECTS
262.
Google’s course of conduct has corrupted the competitive process by which
publishers and advertisers select, and then use, pivotal ad tech tools. In doing so, Google has
undermined publishers’ and advertisers’ ability to make optimal matches for advertising
inventory on mutually agreeable
terms. Google
also has interfered in rivals’ attempts to partner
successfully with Google’s publisher and advertiser customers, thereby limiting the competitive
benefits that would otherwise flow from customers’ ability to effectively multi-home across
competing a
d tech products. Instead of
fostering a competitive and innovative market, Google
has wielded its market power to dictate the terms on which publishers and advertisers do
business, ensuring those terms advance Google’s anticompetitive ends and bottom line rather
than its customers’ best interests.
263.
Google’s conduct, described above, consists of a series of interrelated and
interdependent actions, which have had cumulative and synergistic anticompetitive
effects, the
full scope and effect of which could not be fully
recognized in real time by
anyone outside of
Google.
Google’s anticompetitive conduct includes, but is not limited to:
(1)
Google’s acquisition of
DoubleClick to obtain not only a dominant publisher
ad server, DFP, but also a nascent
ad exchange, AdX, in order to pursue its
goal of dominance across the entire ad tech stack;
(2)
Google’s restriction of Google Ads’ advertiser demand exclusively to AdX;
(3)
Google’s restriction of effective real-time access to AdX exclusively to DFP;
116
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 121 of 153 PageID# 121
(4)
Google’s limitation of dynamic allocation bidding
techniques exclusively to
AdX;
(5)
Google’s providing AdX with a “last look” auction advantage over rival
exchanges;
(6)
Google’s acquisition of
AdMeld to stop its
yield management technology
from
promoting multi-homing across
ad exchanges;
(7)
Google’s use of Project
Bell, which lowered, without advertisers’ permission
or knowledge, bids to publishers who dared partner with Google’s
competitors;
(8)
Google’s deployment of
sell-side Dynamic Revenue Share to manipulate
auction bids—without publishers’ knowledge—to advantage AdX;
(9)
Google’s use of Project Poirot to thwart the competitive threat of header
bidding by secretly and artificially manipulating DV360’s advertiser bids on
rival ad exchanges using he
ader bidding in order to ensure transactions were
won by Google’s AdX; and
(10) Google’s veiled introduction of so-called Unified Pricing Rules that took away
publishers’ power to transact with rival ad exchanges
at preferred prices.
264.
Google’s anticompetitive scheme spans nearly two decades
and continues to the
present. Moreover, the flywheel effects of even the earliest
conduct are lasting, enabling
and
amplifying the impact of
subsequent conduct, and setting in motion Google’s march to an ever-
increasingly
dominant position across the ad tech industry that persists today. Google has
distorted the
competitive
market forces that would otherwise determine prices and output and
would incentivize innovation, efficiency, customer
choice, and control. Google’s
conduct has
preserved Google’s dominant market positions at all levels of the ad tech stack and allowed
117
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 122 of 153 PageID# 122
Google to siphon away a
supra-competitive portion of advertiser dollars before they
can reach
website publishers.
265.
Collectively, by hamstringing rivals’
abilities
to compete on the merits, Google’s
conduct has stifled innovation and limited publisher and advertiser
choice. Google’s conduct has
harmed internet users as
well. Fewer advertising dollars reach website publishersbecause of
higher
ad tech
fees and less efficient advertising matches—meaning those publishers have fewer
resources to create content for internet users. These harmful effects are not just historical; rather,
Google’s anticompetitive conduct continues to affect the marketplace on an ongoing basis.
266.
Higher Prices and Higher Margins for Google. The overarching g
oal of
much of
Google’s conduct has been to force as many transactions as possible (especially high-value
transactions) to flow through its own ad tech
products, with Google
taking
a cut of the
advertising spend at each step of the way. The focal point of Google’s monetization strategy has
been its ad exchange, where it charges
its
highest revenue share
fees: consistently around 20%
for open auction transactions since 2009, while its rivals charged only
a fraction of that amount.
Google’s documents admit that ad exchange technology largely became commoditized
years
ago, and but for Google’s ability to build and defend a moat around its ad tech products,
competition
would have
driven prices down for most transactions by
as much as 75%, especially
where that same advertising demand is otherwise available on
rival ad
exchanges. Instead,
Google has succeeded in defending
its supra-competitive prices for
all transactions
flowing
through its
ad
exchange
without ceding—and indeed growing—its market share
even today.
267.
The revenue share fees Google charges come directly out of advertisers
advertising budgets and ultimately out of website
publishers’ bottom-line revenues. This
means
that advertisers
are able to buy fewer ad impressions at the prices at which
publishers are willing
118
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 123 of 153 PageID# 123
to sell, less advertiser spend makes it to the publishers that internet users rely upon to generate
and disseminate important content, and ultimately
fewer publishers are able to offer internet
users content for free (without subscriptions, paywalls, or alternative
forms of monetization).
268. Scale, Flywheel Effects, and Diminished Multi-Homing. Google’s strategy to
shift additional transactions to its ad exchange and inhibit the ability of publishers and
advertisers to transact effectively through rivals was not merely to charge supra-competitive fees.
Google was also concerned that too many transactions flowing through alternative pipes—other
ad technology platforms—could allow rivals to gain scale and challenge Google’s competitive
moat. The growth of alternative ad tech tools posed a risk of increased competition via more
effective multi-homing, leading to pressure to reduce prices and increase choice and qua lity for
publishers and advertisers.
269. Scale plays a critical role in a company’s ability to offer a competitive ad tech
platform at a low price and high quality. Scale would bestow many advantages on Google’s
potential competitors. These include indirect network and feedback effects to attract more
advertisers and publishers, more data to improve the efficiency of their transactions, and the
opportunity to spread their fixed costs over a larger number of transactions. Google’s conduct
had the purpose and effect of depriving rivals of sufficient scale to meaningfully compete in the
ad exchange, publisher ad server, and advertiser ad network demand markets. Even for conduct
Google ostensibly has discontinued, the effects are persistent and ongoing. Scale builds on itself
and is self-reinforcing. Google’s conduct denying s cale to rivals has had a lasting impact that
continues to affect today’s marketplace.
270. Google has accomplished this objective in a number of ways. Collectively,
Google’s conduct has allowed its ad exchange to win more impressions by providing it with
119
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 124 of 153 PageID# 124
more opportunities to win transactions on preferential terms, initially through programs like
dynamic
allocation and later through the implementation of Project Poirot and Google’s so-
called Unified Pricing Rules. By using Google’s
control of the publisher ad server to give its ad
exchange preferential access to publisher inventory, Google
has been, a
nd continues to be,
able
to drive up rival ad exchanges’ and advertiser
ad networks’ costs;
impede
publishers’ attempts to
identify high-quality, real-time matches through those ad exchanges
and networks;
limit the
ability of ad
exchanges
to win transactions at sufficient scale;
and diminish rival ad exchanges’
ability to attract publishers and advertisers to their platforms.
271.
Rival ad
exchanges
have incurred costs to process
and respond to each bid request
from a publisher, but
have been
unable to effectively
compete on the same terms as Google’s
ad
exchange to win the impression. Because
ad exchanges
are
compensated only on transactions
they win, an ad
exchange’s win rate is critical to the long-term financial viability of the
ad
exchange and its ability to innovate.
272.
Moreover, strong network effects operate in the
publisher ad server, ad exchange,
and advertiser ad network demand markets,
which
are driven largely by scale. Due to indirect
network effects, both advertisers and publishers
are attracted to ad exchanges with more parties
on the other side. A rival
ad exchange that has less scale due to Google’s anticompetitive
conduct is less able to attract and maintain
additional publishers and advertisers; it swims against
the strong c
urrent of indirect market effects that benefit Google’s larger
ad
exchange. Similarly,
for an advertiser
ad network to rival Google Ads’
dominance, it must be able to benefit from
network effects
and have sufficient
access to publisher inventory at scale. A competing
advertiser
ad network
would additionally benefit from
the associated
contextual and user
targeting data
that provide a competitive advantage. Google’s
actions
inhibiting
rival ad
120
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 125 of 153 PageID# 125
networks from
accessing i
nventory on the terms
that publishers prefer
has the effect of
impeding
competition.
The result in both cases is a feedback loop that continues to inhibit the growth of
rivals while preserving G
oogle’s dominant positions.
273.
Additionally, Google’s
conduct
has
succeeded in
locking publishers into Google’s
publisher
ad server. Google’s
restrictions
have rendered
its publisher ad server the only
viable
means
to obtain meaningful access to the unique, sizeable Google
Ads’
advertising demand
available almost exclusively on Google’s ad
exchange,
as well as the other
advertising demand
Google made preferentially available there. Because publishers must
as a practical matter
single-
home with one publisher
ad server, this exclusivity
essentially
compelled publishers to use
Google’s
publisher
ad server and inhibited rivals from entering or remaining in the market. As a
result, a potential competitor to Google’s publisher ad server would need to enter both the
publisher ad server and the ad exchange market, both
at scale, in order
to compete. Only a
rival
ad exchange operating at
scale together with a publisher ad server would
likely
attract
publishers
to switch away from Google’s highly restrictive publisher ad server. Google perceived that
header bidding posed an
existential threat to
its
publisher ad server monopoly because header
bidding
could allow a potential rival to generate sufficient scale in the ad exchange market and,
subsequently, enter the
publisher
ad server market
(or facilitate the entry of a new publisher
ad
server). Google
quashed
that threat and
deprived its rivals of the ability to
gain such scale via
header bidding
or other innovations.
274.
Lack of
Choice and Control
for Publishers and
Advertisers Alike.
Google’s
anticompetitive conduct
has narrowed publishers’ and advertisers’ choices
about how to do
business with one another in several ways. Dynamic allocation prevented publishers from
effectively offering their
inventory on the same terms—or any terms of their choosing—through
121
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 126 of 153 PageID# 126
multiple ad exchanges. Through the Unified Pricing Rules, Google disabled the function in its
publisher ad server that previously
allowed publishers to specify the terms
on which they wished
to transact with ad exchanges
and other sources of advertising demand. And unbeknownst to
advertisers, Project Poirot surreptitiously
discounted t
heir advertising spend on
the ad exchanges
they selected
and
directed
that spend toward Google’s
ad exchange
instead.
275.
More broadly, Google’s
march to monopoly in the publisher ad server market has
left publishers today with basically no choice
when selecting a
publisher ad server. And because
the publisher ad server determines how publisher
ad inventory is awarded to an advertiser,
publishers have no choice but to acquiesce to Google’s
will as to how that process should work.
Competition no longer constrains Google’s ability
to write the
rules in its favor.
276.
Information Asymmetries.
Because Google’s ad
tech
products face little or no
meaningful competition, Google has been able to operate its products within a black box,
affording
publishers and advertisers limited visibility into how, why,
and
even at what price,
website advertising inventory is sold. O
ne industry report suggests that approximately 15% of all
digital advertising spend is simply
unaccounted for, with publishers and advertisers unable to
determine which intermediary may have siphoned this spend off for its own gain. Reduced
transparency diminishes the ability of publishers
and advertisers to make informed choices in
selecting their
ad tech
products and hampers their ability (and rivals’
as well) to serve as a
competitive constraint.
277.
Less Innovation.
Competitive pressure drives innovation, as competitors are
incentivized to develop new ways to outperform one another to attract customers. The lack of
any meaningful competition for
publisher
ad servers has severely dampened innovation in that
market. Reflecting on Google’s dominant sell-side market position, Google
executives noted the
122
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 127 of 153 PageID# 127
weakness that Google “often play[s] fast follow vs first movers.” A more competitive market
would have fostered greater innovation. For instance, if not for
Google’s acquisition of AdMeld
and subsequent deprecation of its
yield optimization technology, real-time bidding among
ad
exchanges may have become available to publishers several
years before the advent of header
bidding, and well before
Open Bidding. Similarly, had Google not had a monopoly of the
publisher ad server market, a rival publisher ad server may have introduced a tool for server-side
real-time bidding among
ad exchanges similar to Open
Bidding. Instead, the industry was forced
to rely on header bidding, which, although useful,
is limited because it serves as a partial
workaround that was not
integrated into a publisher ad server. Moreover, rival
ad exchanges
have been limited in their ability to introduce any innovation that requires the cooperation of a
publisher ad server, even where such cooperation would improve both products. In the absence
of serious competitive pressure, Google has a diminished incentive to improve its publisher
ad
server or ad exchange products.
278.
The United States is among the
advertisers harmed by Google’s anticompetitive
conduct. United States departments and agencies, including ones in this district
such as
the
Army, purchase open web display advertising using Google
and non-Google ad tech tools. Since
2019, the United States has purchased in excess of $100 million in open web display advertising.
The United States has incurred monetary damages
as a result of Google’s anticompetitive
conduct by virtue of the supra-competitive fees, manipulated advertising prices, and lower
quality advertising matches described
above.
VI.
RELEVANT MARKETS
279.
Google’s conduct at issue in this Complaint implicates three relevant antitrust
markets in the United States: publisher ad
servers, ad exchanges, and advertiser ad networks.
123
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 128 of 153 PageID# 128
A.
Geographic Markets
280.
The United States is a relevant
geographic market
for publisher ad servers, ad
exchanges, and advertiser ad networks. Market participants recognize this in the ordinary course
of business. While Google and certain other market participants offer publisher ad servers, ad
exchanges, and advertiser ad networks internationally, there are differences in publisher and
advertiser preferences, language, and regulatory frameworks depending on the
country to which
the publication and/or advertising is intended to be viewed.
281.
In the alternative, a relevant geographic market for publisher ad servers,
ad
exchanges, and advertiser ad networks is worldwide (excluding countries such as the People’s
Republic of China that substantially restrict international internet access).
B.
Product Markets
1.
Publisher Ad Servers
282.
Publisher ad servers for open web display advertising is a relevant
antitrust
product market. For simplicity, this Complaint refers to these products as “publisher ad servers”
or “ad servers.” Google offers DoubleClick for Publishers, now part of the
Google
Ad Manager
suite, as a product in this relevant market.
283.
A publisher uses a publisher ad server to manage the sale of display ads on its
webpages. Publisher
ad servers provide functionality such as
ad delivery, reporting, and
forecasting of availability
across direct deals and
indirect advertising sales. Publisher ad servers
evaluate potential sources of advertising demand and are the final arbiters
of which ad is selected
to fill designated
inventory slots
on a publisher’s
webpage.
284.
Other ad tech products are not reasonable substitutes for publisher
ad servers. As
compared to publisher
ad servers, alternative products—such as publisher ad networks
(including
Google’s AdSense product), ad exchanges, closed web platforms, or mobile app ad mediation
124
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 129 of 153 PageID# 129
platforms—offer different functionality, serve distinct needs for
publishers, use different pricing
structures, and/or monetize different types of digital
ad inventory. Thus, there are no reasonable
substitutes for publisher ad servers, and a publisher ad server monopolist would be able to
maintain prices above the level that would prevail in a competitive market and/or maintain
quality below the level that
would prevail in a competitive market.
285.
Google has maintained a
monopoly in publisher ad servers in the United States
since at least 2015. As confirmed by Google’s internal assessments,
Google’s share of the
publisher ad server market in the United States,
measured by
either revenue or impressions,
has
remained above 90% for
many
years.
Its worldwide market share is similar.
286.
Importantly, Google’s dominance of open web inventory sold via open auction
also gives Google a dominant position with respect to the
sale of other types of valuable
inventory transacted through its publisher ad server. These include directly
sold advertisements
and advertisements sold outside of open auctions
via programmatic
advertising tools, e.g.,
programmatic guaranteed
and
programmatic direct. Although these transactions are not
substitutes for open auction transactions, they
give Google substantial sources of additional
revenue
and data
concerning some of the most sought-after publisher inventory. For
example, in
2021, direct advertisement sales through
DFP represented
over
$11 bi
llion in gross revenues to
publishers, with programmatic guaranteed
and
programmatic direct
representing approximately
$1 billion in gross revenue.
287.
Google has
exploited its
monopoly
power
over
DFP. In 2015, Google developed
technology
within the publisher ad server that was able to support large volumes of
programmatic direct transactions. Google initially planned to enable third parties to implement
the technology via API protocols. By early 2016, Google
recognized that some third-party
125
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 130 of 153 PageID# 130
exchanges were ahead of AdX in developing programmatic direct technologies. To forestall the
development of these competing products, G oogle developed guidelines which prohibited
DV360 from engaging in any engineering w ork to support competing products before a similar
integration was already developed between DV360 and AdX. As a result, competitive product
development and innovation was impeded until Google’s programmatic direct technologies
became the de facto market standard.
288. Google’s durable monopoly power in publisher ad servers is protected by
significant barriers to entry. The cost to build a publisher ad server and achieve the scale
necessary to compete effectively are significant. Publishers typically can only use one publisher
ad server at a time and rarely incur the costs to switch from one to another due to engineering
integration costs and significant disruptions caused by switching. The cost to build a publisher ad
server is significant, and barriers to entry are reinforced by Google’s anticompetitive conduct in
the market.
289. Google’s monopoly power in publisher ad servers is further evidenced by
Google’s ability to engage in conduct that benefits itself at the expense of publishers without
inducing them to switch to an alternative publisher ad server. Moreover, Google’s monopoly
power in publisher ad servers is protected by Google’s anticompetitive conduct described herein.
2. Ad Exchanges
290. The market for ad exchanges for indirect open web display advertising is a
relevant antitrust product market. For simplicity, this Complaint refers to these products as “ad
exchanges.” Google offers AdX, now part of the Google Ad Manager suite, as a product in this
relevant market.
291. Publishers use ad exchanges to auction display ad inventory, and advertisers
(through advertiser buying tools) use ad exchanges to purchase that inventory. Alternative
126
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 131 of 153 PageID# 131
methods and products for transacting ad inventory
are not reasonable substitutes for advertisers
and publishers. As compared to ad exchanges, alternative methods and products for selling a
d
inventory—such as direct deals,
programmatic
guaranteed, traditional ad networks
(those not
relying on
real-time bidding), closed web platforms, or other ad tech tools for other types of
digital advertising—are distinct in terms of inventory type, use cases, functionality, inventory
constraints, and/or monetization. Thus, there are no reasonable substitutes for ad exchanges, and
an ad exchange monopolist would be able to maintain prices above the level that would prevail
in a competitive market and/or maintain quality below the level that would
prevail in a
competitive market.
292.
Google enjoys
substantial and growing market share
with respect to ad exchanges
in the United States. Google’s
AdX is the largest ad exchange in the market; it is approximately
four times larger than the next largest ad exchange, whether measured by impressions won or by
revenue,
and has been for at least several
years. For open web advertisements sold via open
auctions, Google’s ad
exchange is the direct winner of
more than
50% of
all ad impressions and
revenue. Its worldwide market share is higher.
293.
In addition, Google
also controls the Open Bidding system through which other
ad exchanges may purchase publisher ad inventory, but only by paying Google
a 5% revenue
share fee, sharing important bid data with Google, and restricting the demand used to compete in
the auction. Open Bidding presently represents another approximately 7%
of all U.S. advertising
impressions won via open auction. As a result, Google has either full (AdX-won impressions) or
partial (Open Bidding-won transactions) control over, and visibility into, most open auction
transactions.
127
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 132 of 153 PageID# 132
294.
Through the conduct described above, including e
nhanced dynamic allocation and
the integration of AdX into Google Ad Manager, Google has ensured that
AdX is used as an ad
exchange by publishers representing more than 90% of all open web display
advertisements
available for auction. Google estimates that AdX is able to see and bid
on 77% of open web
impressions and that it could profitably force publishers to use AdX by default. By
contrast, all
other ad exchanges must
compete to be adopted by
publishers
as a secondary
ad exchange before
they
are
able to see inventory on which to bid.
295.
Google’s share in the ad exchange market, if
anything, understates AdX’s
competitive significance. Many
ad exchanges still compete for publisher ad inventory via the
“waterfall” method, which does not allow for real-time competition among e
xchanges and is not
a close substitute. Excluding transactions that occur via the waterfall method would significantly
increase Google’s share of the ad exchange market. Additionally,
because
AdX has superior
access to unique sources
of demand from
Google
Ads,
it is a
must-have ad
exchange for nearly
all website publishers; other ad exchanges do not have access to similar sources of unique
demand. And AdX is also one of the only exchanges
connected to both a publisher ad server and
advertising buying tool owned by the same company.
296.
Google’s
monopoly
power in ad exchanges is further evidenced by Google’s
ability to engage in conduct that benefits itself at the expense of publishers
and advertisers
without inducing them to switch away from AdX
and relying exclusively on alternative ad
exchanges. This conduct
has
denied scale to rivals and has
allowed Google to
maintain
a supra-
competitive
revenue share for its ad exchange for
over a decade, despite internal documents
suggesting a
competitive price would be much lower. In addition, Google’s
monopoly
power
in
ad exchanges is protected by its anticompetitive conduct described herein.

3.
Advertiser Ad Networks
297.
Advertiser ad networks for open web display
advertising is a relevant antitrust
market. An advertiser
ad network provides easy-to-use, self-service
bidding tools that facilitate
ad placement on open web display ad inventory. Advertiser ad networks are accessible to less
sophisticated advertisers, although sophisticated advertisers may also use them. Advertiser
ad
networks typically configure their simple bidding tool with proprietary targeting data that
uniquely values website
publisher inventory based on a combination of data sources, including
information about the website, where the
ad will be displayed, and the particular user visiting the
website. Advertiser ad networks typically
charge advertisers on a
cost-per-click basis rather than
a cost-per-impression basis. Because advertiser
ad networks
generally purchase advertising
inventory on a cost-per-impression basis, they must have substantial data and scale to
successfully predict the likelihood the user will click on the advertisement and thereby
effectively arbitrage the difference between their
cost to acquire inventory
and the cost-per-click
price charged to
advertisers.
298.
Google’s advertiser ad network for open web display
ads has been called the
Google
Display Network (GDN”), and is
a portion of Google’s Google
Ads product (formerly
known as AdWords).
299.
Many
advertisers that use advertiser ad networks
continue to be
significantly
limited in their abilities to substitute all or most of their advertising spend to demand side
platforms (or DSPs”), the other major
advertiser
buying tool for accessing open-web inventory.
DSPs require the buyer to directly manage their advertising campaigns, are not reasonably
accessible to less sophisticated advertisers, and often require buyers to utilize their own
proprietary data to effectively bid on advertising inventory. Google has described the distinction
129
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 134 of 153 PageID# 134
between advertiser ad networks like Google Ads and demand side platforms like Google’s
Display & Video 360 (DV360) as follows:
Fig. 21
300. Advertising networks that facilitate the sale of digital advertising on search, social
media, or app platforms do not purchase inventory from such open web website publishers and
have distinct, more limited reach.
301. Google has monopoly power in the relevant market for advertiser ad networks.
Google built the open web display advertising component of Google Ads by providing easily
accessible bidding tools for advertisers, including less sophisticated advertisers. Google
documents state that Google Ads provides access to over 2 million websites and reaches over
90% of internet users. Google Ads’ United States and worldwide shares of the market for
advertiser ad networks for open web display advertising has not dropped below 70% (measured
by impressions) since 2015; it currently stands at around 80%. Google experimented with
increasing the revenue share charged on advertising demand available through Google Ads, and
found that it could profitably impose an increase in excess of 5%. This demonstrates that
advertisers would not substitute away from Google Ads to any alternative ad buying tool in
sufficient volume to defeat such a price increase.
302. Google’s market power in advertiser ad networks for open web display ads is
protected by significant barriers to entry. Google was able to build Google Ads’ large pool of
unique, often small, advertisers through its search product, as it was able to opt search advertisers
130
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 135 of 153 PageID# 135
into extending their campaigns into open web display. Few
companies have such a product
available, nor
could one
be readily built for this purpose.
303.
Any
advertiser ad network seeking to compete meaningfully with Google
Ads
would need to build a large enough pool of advertiser demand to be attractive to ad exchanges
and publishers. Building s
uch a pool is difficult, even for well-funded market participants.
VII.
JURISDICTION, VENUE,
AND COMMERCE
304.
The United States brings
this action pursuant to Section 4 of the Sherman Act,
15 U.S.C. § 4, to prevent and restrain Google’s violations of Sections 1 and 2 of the Sherman
Act, 15 U.S.C. §§ 1, 2.
305.
Plaintiffs California, Colorado, Connecticut, New Jersey, New York, Rhode
Island, Tennessee,
and Virginia by and through their respective Attorneys
General, bring this
action pursuant to Section 16 of the Clayton Act, 15 U.S.C. § 26, to prevent and restrain
Google’s violations of Sections 1 and 2 of the Sherman Act, 15 U.S.C. §§ 1, 2.
306.
This Court has subject matter jurisdiction over this action under Section 4 of the
Sherman Act, 15 U.S.C. § 4, and 28 U.S.C. §§ 1331, 1337(a), and 1345.
307.
The Court has personal jurisdiction over Google;
venue is proper in this District
under Section 12 of the
Clayton Act, 15 U.S.C. § 22, and under 28 U.S.C. § 1391 because
Google transacts business and is found within this District.
308.
Google is
a limited liability company organized and existing under the laws of the
State of Delaware
and is headquartered in Mountain View, California. Google is owned by
Alphabet
Inc., a publicly
traded company incorporated and existing under the laws of the State of
Delaware and headquartered in Mountain View, California. Google’s display
advertising
business is part of its “Ads” unit, which consists of Google’s YouTube, search, shopping, and
131
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 136 of 153 PageID# 136
non-search display advertising businesses. In 2021, Alphabet recorded nearly $260 billion in
revenue, a 41% increase
over 2020. Alphabet’s “Google Network” revenue, which represents
non-search display advertising revenue from Google’s
AdMob, Ad Manager, and AdSense
products, among others, generated $31.7 billion in 2021, a 37%
increase over 2020 revenue.
309.
Google
engages in, and its activities substantially
affect, interstate trade and
commerce. Google provides a range of products and services that are marketed, distributed, and
offered to consumers throughout the United States, in the plaintiff States, across
state lines, and
internationally.
VIII.
VIOLATIONS ALLEGED
First Claim for Relief: Monopolization of the Publisher Ad
Server Market in
Violation of
Sherman Act § 2
310.
Plaintiffs incorporate the
allegations of paragraphs 1 through 309 above.
311.
Publisher ad servers for open web display advertising in the United States or, in
the alternative, worldwide is a relevant antitrust market, and Google has monopoly power in that
market.
312.
Google has unlawfully monopolized the publisher ad server market through a
course of
exclusionary
conduct described herein. While each of Google’s actions increased,
maintained, or protected its publisher ad server monopoly and/or market power in adjacent
markets, the following exclusionary conduct—taken togetherplayed a particularly important
role in unlawfully establishing or maintaining a publisher ad server monopoly:
(1)
Google’s acquisition of
DoubleClick to obtain not only a dominant publisher ad
server, DFP, but also a nascent ad exchange, AdX, in order to pursue its
goal of
dominance across the entire ad tech stack;
(2) Google’s
restriction of Google Ads’
advertiser demand exclusively to AdX;
132
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 137 of 153 PageID# 137
(3)
Google’s
restriction of effective real-time access to AdX exclusively to DFP;
(4)
Google’s limitation of dynamic allocation bidding techniques exclusively to
AdX;
(5)
Google’s providing A
dX with a “last look” auction advantage over rival exchanges;
(6)
Google’s
acquisition of AdMeld to stop its
yield management technology from
promoting multi-homing across
ad exchanges;
(7)
Google’s use of Project Bell, which lowered, without advertisers’ permission, bids to
publishers who dared partner with
Google’s competitors;
(8)
Google’s deployment of
sell-side Dynamic Revenue Share to manipulate auction
bids—again, without publishers’ knowledge—to advantage AdX;
(9)
Google’s use of Project Poirot to thwart the competitive threat of header bidding by
secretly
and artificially manipulating
DV360’s
advertiser bids on rival ad exchanges
using header bidding in order to ensure transactions were won by
Google’s
AdX; and
(10)
Google’s veiled introduction of so-called Unified Pricing Rules that took away
publishers’ power to transact with rival ad exchanges
at preferred prices.
313.
Although each of these acts is anticompetitive in its own right, these interrelated
and interdependent actions have had a cumulative and synergistic effect that has harmed
competition and the competitive process.
314.
Google’s exclusionary conduct has foreclosed a substantial share of the publisher
ad server market.
315.
Google’s anticompetitive acts have had harmful
effects on competition and
consumers.
316.
Google’s exclusionary conduct
lacks a procompetitive justification that offsets the
harm caused by Google’s anticompetitive and unlawful conduct.

Second Claim for Relief:
Monopolization of the Ad Exchange Market
in
Violation of Sherman
Act § 2
317.
Plaintiffs incorporate the
allegations of paragraphs 1 through 309
above.
318.
Ad exchanges for open web display
advertising in the United States
or, in the
alternative, worldwide
is a relevant antitrust market, and Google has monopoly power in that
market.
319.
Google has unlawfully monopolized the ad exchange market through an
exclusionary course of
conduct and the anticompetitive acts described herein. While each of
Google’s actions
collectively increased, maintained, or protected its ad exchange monopoly
and/or market power in adjacent markets, the following exclusionary conduct—taken together
played a particularly important role in unlawfully
establishing or maintaining an ad exchange
monopoly:
(1)
Google’s
acquisition of DoubleClick to obtain not only a dominant publisher ad
server, DFP, but also a nascent ad exchange, AdX, in order to pursue its
goal of
dominance across the entire ad tech stack;
(2)
Google’s
restriction of
Google Ads’
advertiser demand exclusively to AdX;
(3)
Google’s
restriction of effective real-time access to AdX exclusively to DFP;
(4)
Google’s limitation of dynamic allocation bidding techniques exclusively to AdX;
(5)
Google’s providing A
dX
with a “last look” auction advantage over rival exchanges;
(6)
Google’s
acquisition of AdMeld to stop its
yield management technology from
promoting multi-homing across
ad exchanges;
(7)
Google’s use of Project Bell, which lowered, without advertisers’ permission, bids to
publishers who dared partner with
Google’s competitors;
134
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 139 of 153 PageID# 139
(8)
Google’s deployment of
sell-side Dynamic Revenue Share to manipulate auction
bids—again, without publishers’

(9)
Google’s use of Project Poirot to thwart the competitive threat of header bidding by
secretly
and artificially manipulating
DV360’s
advertiser bids on rival ad exchanges
using header bidding in order to ensure transactions were won by
Google’s
AdX; and
(10)
Google’s veiled introduction of so-called Unified Pricing Rules that took away
publishers’ power to transact with rival ad exchanges
at certain prices.
320.
Although each of these acts is
anticompetitive in
its
own right, these interrelated
and interdependent actions have had a cumulative and synergistic effect that has harmed
competition and the competitive process.
321.
Google’s conduct has drastically altered the supply
paths through which available
display advertising inventory is sold, reducing payouts to publishers, burdening advertisers and
publishers with lower-quality matches of advertisements to inventory, and inhibiting choice and
innovation across the ad tech stack.
322.
Google’s anticompetitive acts have had harmful
effects on competition and
consumers.
323.
Google’s exclusionary conduct
lacks a procompetitive justification that offsets the
harm caused by Google’s anticompetitive and unlawful conduct.
Second Claim for Relief, in the Alternative: Attempted Monopolization of the Ad Exchange
Market
in Violation of Sherman Act § 2
324.
Plaintiffs incorporate the
allegations of paragraphs 1 through 309
above.
325.
Ad exchanges for open web display
advertising in the United States
or, in the
alternative, worldwide
is a relevant antitrust market, and Google has attempted to monopolize
that market.
135
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 140 of 153 PageID# 140
326.
Google has attempted to monopolize the ad exchange market through an
exclusionary course of
conduct and the anticompetitive acts described herein. While each of
Google’s actions collectively increased Google’s
market power
in the ad exchange and adjacent
markets, the following exclusionary conduct—taken togetherplayed a particularly important
role in Google’s attempt
to attain an ad exchange
monopoly:
(1)
Google’s
acquisition of DoubleClick to obtain not only a dominant
publisher ad
server, DFP, but also a nascent ad exchange, AdX, in order to pursue its
goal of
dominance across the entire ad tech stack;
(2)
Google’s
restriction of Google Ad’s
advertiser demand exclusively to AdX;
(3)
Google’s
restriction of effective real-time access to AdX exclusively to DFP;
(4)
Google’s limitation of dynamic allocation bidding techniques exclusively to AdX;
(5)
Google’s providing A
dX with a “last look” auction advantage over rival exchanges;
(6)
Google’s acquisition of AdMeld to stop its
yield management technology from
promoting multi-homing across
ad exchanges;
(7)
Google’s use of Project Bell, which lowered, without advertisers’ permission, bids to
publishers who dared
partner with
Google’s competitors;
(8)
Google’s deployment of
sell-side Dynamic Revenue Share to manipulate auction
bids—again, without publishers’ knowledge—to advantage AdX;
(9)
Google’s use of Project Poirot to thwart the competitive threat of header bidding by
secretly and
artificially manipulating
DV360’s
advertiser bids on rival ad exchanges
using header bidding in order to ensure transactions were won by
Google’s
AdX; and
(10)
Google’s veiled introduction of so-called Unified Pricing Rules that took away
publishers’ power to transact with rival ad exchanges
at certain prices.
136
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 141 of 153 PageID# 141
327.
Although each of these acts is
anticompetitive in
its
own right, these interrelated
and interdependent actions have had a cumulative and synergistic effect that has harmed
competition and the competitive process.
328.
In undertaking this course of conduct, Google has
acted with a specific intent to
monopolize, and to destroy effective competition in, the ad exchange market in the United
States. There is a dangerous probability that, unless restrained, Google will
succeed in
monopolizing the ad exchange market, in violation of Section 2 of the Sherman Act.
329.
Google’s conduct has drastically altered the supply
paths through which available
display advertising inventory is sold, reducing payouts to publishers, burdening advertisers and
publishers with lower-quality matches of advertisements to inventory, and inhibiting choice and
innovation across the ad tech stack.
Third Claim for Relief: Monopolization of the Advertiser Ad Network Market
in Violation of
Sherman Act § 2
330.
Plaintiffs incorporate the
allegations of paragraphs 1 through 309
above.
331.
Advertiser ad networks for open web display
advertising in the United States
or,
in the alternative, worldwide
is a relevant antitrust market, and Google has monopoly power in
that market.
332.
Google has unlawfully maintained its monopoly in the advertiser
ad network
market through an exclusionary
course
of conduct and the anticompetitive acts described herein.
While
each of Google’s actions collectively increased, maintained, or protected its advertiser
ad
network monopoly
and/or market position in adjacent markets, its veiled introduction of so-
called Unified Pricing Rules that took away publishers’ power to transact
with rival advertiser
ad
networks at certain prices
played
a particularly important role in unlawfully
establishing or
maintaining an advertiser ad network monopoly.
137
Case 1:23-cv-00108 Document 1 Filed 01/24/23 Page 142 of 153 PageID# 142
333.
Google’s conduct has drastically altered the supply
paths through which available
display advertising inventory is sold, reducing payouts to publishers, burdening advertisers and
publishers with lower-quality matches of advertisements to inventory, and inhibiting choice and
innovation across the ad tech stack.
334.
Google’s anticompetitive acts have had harmful
effects on competition and
consumers.
335.
Google’s exclusionary conduct
lacks a procompetitive justification that offsets the
harm caused by Google’s anticompetitive and unlawful conduct.
Fourth
Claim for Relief: Unlawful Tying
in Violation of
Sherman Act §§ 1 and 2
336.
Plaintiffs incorporate the
allegations of paragraphs 1 through 309
above.
337.
Google’s AdX and DFP
are separate and distinct
products. They are sold in
different markets; their functions are different; there is separate demand for them;
and they have
been treated by Google
and by other industry participants as separate products.
338.
Google’s AdX has sufficient market power in the
market for
ad exchanges
for
open web display advertising in the United States
to coerce publishers to license DFP, thus
restraining competition in the market for publisher ad servers for open web display advertising in
the United States.
AdX
was viewed
as a “must-have” product in part because of its exclusive
access to Google Ads’ demand. Google compels
publishers to use DFP to access real-time
competition between AdX and other demand sources. The only viable
economic option for many
publishers is to use DFP because
choosing a rival
platform would require the publisher to lose
access to economically essential, real-time, competitive advertiser demand.
339.
Google’s tying
arrangement affects a substantial volume of commerce in the
publisher ad server market and has substantially
foreclosed competition in the publisher ad
server market. Google’s tying arrangement has excluded competition in the publisher ad server
138
market. Google’s tying arrangement has further caused competing ad servers substantial
damages as a direct and proximate cause of this unlawful conduct because Google has foreclosed
other ad servers from competing for potential publishers and has deprived ad servers of other
business for reasons having nothing to do with the merits of DFP.
Fifth Claim for Relief: Damages Incurred by the United States by Reason of Google’s
Violations of the Antitrust Laws, 15 U.S.C. § 15a
340. Plaintiffs incorporate the allegations of paragraphs 1 through 309 above.
341. Google’s violations of the Sherman Act have caused the United States to incur
monetary damages, as the United States and its various agencies and departments are buyers of
open web display advertising.
IX. REQUEST FOR RELIEF
342. To remedy these illegal acts, Plaintiffs request that the Court:
1. Adjudge and decree that Google has acted unlawfully to monopolize the
publisher ad server market in the United States in violation of Section 2 of
the Sherman Act, 15 U.S.C. § 2;
2. Adjudge and decree that Google has acted unlawfully to monopolize, or,
in the alternative, attempt to monopolize, the ad exchange market in the
United States in violation of Section 2 of the Sherman Act, 15 U.S.C. § 2;
3. Adjudge and decree that Google has acted unlawfully to monopolize the
advertiser ad network market in the United States in violation of Section 2
of the Sherman Act, 15 U.S.C. § 2;
4. Adjudge and decree that Google has acted unlawfully by tying AdX and
DFP in violation of Sections 1 and 2 of the Sherman Act, 15 U.S.C. §§ 1,
2.
