Google has monopolised the expertise used to purchase and promote on-line show advertisements by proscribing or eliminating the alternatives of its clients — each web site publishers and advertisers — the US justice division alleged at a federal antitrust trial.
Antitrust enforcers have sought as an instance how the Alphabet unit’s complicated advert ecosystem works and the methods during which the corporate allegedly manipulated the options of its merchandise and the principles of its auctions to its personal profit. During the last two weeks on the trial, they accused Google of abusing its market energy in three areas: sell-side instruments utilized by web sites, known as advert servers; promoting exchanges; and buy-side instruments utilized by advertisers generally known as advert networks.
Web site publishers use an advert server to handle house obtainable on the market. The advert server acts because the mind for the web site, retaining observe of the minimal bids a writer is keen to simply accept, what has been bought and for the way a lot. The justice division estimates that Google’s advert server controls 87% of the US market and 91% of the market globally.
Advert exchanges management the auctions that match web site publishers with advertisers. Google operates the biggest change, generally known as AdX, later rebranded as Google Advert Supervisor. The justice division estimates that Google’s advert change controls 47% of the US market and 56% globally. Different fashionable advert exchanges embody Pubmatic, Index Trade and Magnite.
Refined advertisers use software program generally known as a demand-side platform to handle their advertisements and assist decide which advert exchanges to bid on and for the way a lot. Google operates a demand-side platform that may bid on an advert change.
Advertisers additionally use advert networks, which take over a lot of the decision-making processes like the place to position advertisements and what to bid and are most frequently utilized by smaller corporations. The justice division alleges that Google’s community, Google Advertisements, controls 88% of the US market and 87% globally.
Antitrust enforcers alleged that Google gave particular entry and privileges to its personal advert merchandise to encourage each advertisers and web sites to spend solely via its providers.
Mischaracterisation
Google has argued that the justice division’s case misunderstands the dynamics, tempo of innovation and aggressive panorama throughout the internet marketing market. Advertisers have a number of decisions for the place to purchase advertisements, the corporate mentioned, together with Amazon.com, Meta Platforms’ Fb and Instagram, in addition to Amazon.com and ByteDance’s TikTok.
The corporate additionally mentioned that lots of the justice division’s contentions mischaracterise how the expertise operates. Modifications to the ad-tech platform have been supposed to enhance the product, Google mentioned. The constraints on rivals’ entry have been in place to scale back spam and advert fraud or assist advertisers have higher management over the place advertisements appeared, the corporate mentioned.
As one promoting govt wrote in a 2017 e-mail to her boss: “The worth in Google’s advert tech stack is much less in every particular person product however within the connections throughout all of them.”

Advertisers utilizing the Google Advertisements community are solely permitted to position bids via Google’s personal change, AdX, with a couple of restricted exceptions. That offers AdX a big quantity of advertisements. In 2020, for instance, Google Advertisements despatched in bids for 18 million advertisements bought via AdX, however solely about three million to 4 million to third-party exchanges. The tight connection between the merchandise requires any web sites that need Google Advertisements promoting to make use of AdX.
Equally, sure capabilities of Google’s advert change, similar to real-time bidding, are solely obtainable to publishers that use its advert server, DFP, in keeping with the justice division.
“Clients are primarily compelled to make use of DFP to get entry to AdX,” mentioned Rosa Abrantes-Metz, the justice division’s financial skilled. Likewise “AdX is the one channel to achieve Google Advertisements in full.”
Well-liked web sites testified that they felt compelled to make use of Google’s advert server product due to its unique entry to Google Advertisements.
“I felt like they have been holding us hostage,” mentioned Stephanie Layser, previously a high govt at Information Corp answerable for the media firm’s use of promoting expertise. Google’s advert server expertise, developed a long time in the past, was “sluggish and clunky”, she mentioned, however Information Corp estimated it’d lose as a lot as US$9-million/yr if it moved to a unique server as a result of it could lose entry to Google Advertisements.
Corporations that work with advertisers mentioned that they had to make use of Google’s advert change, despite the fact that it fees increased charges than others, to make sure that they had sufficient entry to web site stock.
Google has argued that it has no obligation beneath the regulation to make its merchandise work with these supplied by rivals. The requirement that Google Advertisements bid nearly solely via AdX helps the corporate higher handle spam and advert fraud, firm workers testified.
In 2015, Google launched a programme known as AdWords Bidding that allowed extra exchanges to bid on Google’s stock. Nevertheless it was restricted to advert retargeting campaigns, by which entrepreneurs attain out to customers who’ve visited their web site previously.
Opening up the platform to permit extra exchanges to bid on Google’s stock required an enormous carry from the corporate’s inner engineering groups to work via others’ issues with high quality, testified Nirmal Jayaram, a Google engineer who labored on the corporate’s promoting instruments for entrepreneurs.
‘Waterfall’ technique
Earlier than 2015, on-line show advertisements have been bought utilizing a “waterfall” technique. An internet site’s advert server would ask every promoting change for bids sequentially. If the primary change had an advertiser keen to pay an internet site’s minimal bid, the method ended. Subsequent exchanges solely obtained to bid if the primary one didn’t desire a specific advert impression, even when they’d have been keen to pay extra.
The vast majority of web sites used Google’s advert server, which might routinely name on Google’s advert change to bid first, in keeping with the justice division. That benefit allowed Google to win most frequently. Even web sites that used a unique advert server tended to hunt out Google’s change first due to its unique entry to advertisers utilizing Google Advertisements.
Fb’s Brian Boland, who helmed the social community’s advert tech instruments for a decade, likened this to Google getting to choose the perfect apples out of a crate earlier than another change.

Google was conscious of its benefit. “It’s strategic for us to have the AdServer being the choice maker to make sure” Google’s advertiser product “has first-look entry”, Eisar Lipkovitz, who headed the corporate’s show advert enterprise from 2014 to 2019, wrote in an e-mail change with different Google colleagues.
Gabriel Weintraub, an skilled who testified for the justice division, estimated that Google’s first look decreased the share of bids that rival exchanges noticed by about 25%.
Google mentioned the DOJ’s descriptions of how the advert server labored mischaracterise the expertise and that it was technically potential for web sites to maneuver one other change in entrance of Google’s AdX within the waterfall. Few publishers used this system, the corporate mentioned, as a result of they needed to hunt bids from the advertisers who had already chosen to work with Google.
In 2010, Google grew to become fearful about opponents generally known as yield administration methods, which helped web sites analyse historic advert efficiency and decide what order to hunt bids from the completely different advert exchanges. In an inner presentation, Google workers mentioned that the rival instruments prevented Google’s promoting change from seeing the entire obtainable writer stock.
On the time, some publishers have been extra snug with these instruments as a result of they nonetheless hadn’t wrapped their heads round among the new options Google was providing, together with real-time bidding, in keeping with Neal Mohan, a pacesetter in Google’s show promoting enterprise who later grew to become CEO at YouTube. Mohan likened yield managers to DVDs in a world with modern-day video streaming, framing the instruments as outdated tech.
However as a result of publishers nonetheless used them, Google was all in favour of buying an organization that made them. In response to paperwork proven in courtroom, in 2008, Mohan recommended “selecting up the one with essentially the most traction and parking it someplace”.
Google finally determined to purchase a number one yield supervisor, AdMeld, for greater than $400-million in 2011. The search big included a few of AdMeld’s expertise into its personal advert change, after which shut down the service in 2013.
DOJ skilled Abrantes-Metz mentioned Google’s buy of AdMeld was a basic “killer acquisition” — shopping for a possible rival and deprecating the options that threatened its personal product.
By 2015, web sites had turn into pissed off with Google and began utilizing an alternate expertise, generally known as header bidding, which moved the bidding course of exterior of the advert server. With header bidding, a writer would add code to the web site in order that an public sale would happen throughout the browser as a web page was loading. This allowed web sites to concurrently search bids from all exchanges and choose the one that will pay essentially the most.
Open the envelope
After the public sale had ended, the web site would ship the data to the advert server. As a result of Google’s advert server is tied into its change, although, the corporate had a chance to determine whether or not it needed to pre-empt the winner and take the advert for itself. Legal professionals for the justice division argued that this allowed Google to win advertisements with out having to instantly compete in opposition to different exchanges. The informational benefit additionally allowed Google to regulate its personal bids downward because it had extra knowledge on the very best bids coming from different exchanges, the DOJ mentioned.
Abrantes-Metz, the justice division skilled, likened it to having different exchanges participate in a sealed bid public sale, however letting Google open the envelope on the finish.

Google acknowledged this benefit in its inner paperwork. Google’s instruments “have visibility in to remnant value earlier than they submit bids (generally referred to out there as ‘final look’)”, one presentation mentioned. However the firm’s attorneys additionally argued that rival advert exchanges might have constructed integrations with its advert server that they selected to not do as a result of it was pricey.
“Each publishers and exchanges have very strongly complained concerning the equity of” final look, one other Google worker wrote in a 2016 e-mail.
Weintraub estimated that Google’s final look benefit elevated the quantity of advert spend on its platform by $473-million/yr.
Google argues that web sites might keep away from giving its change a final look, however that almost all publishers opted to permit it to bid due to the better demand in Google Advertisements. The corporate additionally mentioned that when Google’s change gained a “final look”, that led to increased income for publishers.
Google’s promoting change, AdX, fees a 20% payment on profitable bids. However in 2014, Google launched a mechanism, known as Dynamic Income Share, that will permit AdX to differ the payment if that will assist an advertiser to win. The system would preserve observe of when it had given an advertiser a reduced payment on a specific bid and make up the distinction in a later public sale.
The search big was solely in a position to implement DRS due to its final look benefit, Weintraub mentioned, since Google knew what value it wanted to beat with the intention to win. He estimated that it elevated advert spending on Google’s change by about $162-million/yr.
“As a result of they might see all of the bids, they might alter the rev share on the finish,” Brian O’Kelley, the previous CEO of AppNexus, a rival advert change that was later bought by AT&T after which Microsoft. “As a result of they have been on the finish of the method, as a result of they owned the advert server, they might win that impression.”
Google argues that the mechanism helped publishers as a result of they made extra money from their advert stock. In a single 2019 experiment the corporate carried out internally, it discovered that the DRS led to a rise of as a lot as 4% in writer income.
After the introduction of header bidding, Google found that web sites would usually give AdX a better minimal value to compensate for its final look benefit.
In 2019, Google launched Unified Pricing Guidelines, which eradicated the power of internet sites to offer Google’s change a better minimal value than different exchanges.
Sad
Web site publishers have been very sad with the change. At an April 2019 assembly with high publishers the place Google introduced the brand new guidelines, a number of web sites expressed concern that Google was eliminating a key device they used to regulate how exchanges bid on advertisements.
The brand new guidelines “stopped our skill to set flooring as we want”, Michael Wheatland, an govt with the UK’s Each day Mail newspaper, testified. After the principles have been adopted, the newspaper noticed thrice as a lot of its advert stock bought via AdX, he mentioned.

The brand new guidelines harm publishers by limiting their skill to tell apart between completely different exchanges, DOJ skilled Weintraub mentioned. He estimated the principles pushed as a lot as $221-million in promoting spend annually to AdX.
Google disputes Weintraub’s evaluation of the influence of the principles, attributing them to a separate change in bidding order. — Leah Nylen and Davey Alba, (c) 2024 Bloomberg LP
