Gatekeepers’ provision of online advertising services*

The conditions under which gatekeepers provide online advertising services to business users, including both advertisers and publishers, are often non-transparent and opaque. This often leads to a lack of information for advertisers and publishers about the effect of a given advertisement. To further enhance fairness, transparency and contestability of online advertising services listed in the designation decision, as well as those that are fully integrated with other core platform services of the same undertaking, gatekeepers should provide advertisers and publishers, and third parties authorised by advertisers and publishers, when requested, with free of charge access to the gatekeepers’ performance measuring tools and the data, including aggregated and non-aggregated data, necessary for advertisers, authorised third parties such as advertising agencies acting on behalf of a company placing advertising, as well as for publishers to carry out their own independent verification of the provision of the relevant online advertising services.
