Background and Key Players
Google, a US-based multinational technology company, derives the majority of its revenue from advertising. The European Commission (EC) has imposed a fine of €2.95 billion on Google for violating the EU’s anti-competitive regulations by distorting competition in the ad tech sector. Google favored its own online display advertising technology services over competitors, affecting other service providers, advertisers, and online publishers.
The ad tech sector comprises digital tools for real-time, non-search-related online advertising, such as banner ads on newspaper websites. The industry offers three main digital tools: (i) ad servers for publishers, used to manage ad space on websites and apps; (ii) programmatic ad-buying tools for open web, used by advertisers to manage automated ad campaigns; and (iii) ad exchange platforms where demand and supply meet in real-time, usually through auctions, to buy and sell display ads.
Google provides several intermediary ad tech services between advertisers and publishers for displaying ads on websites or mobile apps. These include: (i) two ad-buying tools, “Google Ads” and “DV360”; (ii) a publisher ad server, “DoubleClick For Publishers” or DFP; and (iii) an ad exchange platform, “AdX.”
The Infraction
The EC concluded that Google holds a dominant position in two markets: (i) the ad server market for publishers with its “DFP” service; and (ii) the programmatic ad-buying market for open web with its “Google Ads” and “DV360” services, covering the entire European Economic Area.
The EC found that Google abused its dominant position between 2014 and the present by:
- Favoring its own ad exchange, AdX, in the ad selection process managed by its dominant publisher ad server, DFP. For example, Google informed AdX of the best competitor offer it needed to surpass for winning the auction.
- Favoring AdX in how its ad-buying tools, Google Ads and DV360, make offers on ad exchanges. Google Avoided competitors’ advertising exchange platforms and primarily bid on AdX, making it the most attractive platform.
These practices intentionally gave AdX a competitive advantage and could have excluded competing ad exchange platforms. This strengthened AdX’s central role in the ad tech supply chain and Google’s ability to charge high fees for its service.
EC’s Orders and Google’s Response
The EC ordered Google to stop these self-preferencing practices and implement measures to eliminate inherent conflicts of interest along the ad tech supply chain. Google has 60 days to inform the EC on how it plans to do so.
The €2.95 billion fine was determined based on the EC’s 2006 guidelines for fines. The EC considered factors like infringement duration and severity, relevant business volume of AdX in the EEA, and Google’s previous anti-competitive fines.
The EC’s conclusion of Google’s dominant position abuse, similar to the behavior investigated by the US Department of Justice, is also significant for an upcoming US lawsuit starting September 22, 2025.
