RTB House’s First Impressions on Google Chrome’s Topics API
Six months ago, during IETF 111, Google engineers made it clear that they were approaching a new iteration of FLoC, which was related to site topics. Yesterday, they finally announced Topics API. The ad topics concept has also been explored by Meta engineers in their Ad Topic Hints proposal, which builds on user feedback to displayed ads. Also, the PAURAQUE proposal from NextRoll was proposed in such a way that users could define topics which are interesting for them and can be used for personalization.

Cookies deadline extension allows for further testing and for Google to provide incentives to accelerate adoption
A year after the previous extension of the deadline for third-party cookies deprecation, Google did it again, this time until the second half of 2024 [Note: In April 2024, it was further postponed until early 2025]. At the same time, Google released two important pieces of information: The FLEDGE origin trial will most likely be extended until late October and will also cover Chrome stable users, and the feedback report for Q2, which is a result of the company’s commitments to the CMA.

RTB House Perspective on Google’s Topics Experiment Whitepaper
On April 18th, Google published the results from Google Ads’ interest-based advertising testing, where, among other tools, Topics API was analyzed. We are happy that the Google Ads team joined RTB House and Criteo in openly publishing findings from experiments with Privacy Sandbox APIs.

In the report, the Google Ads team compares the effectiveness of applying Topics API, contextual signals, and publisher first-party IDs instead of cookies for Interest-Based Advertising (IBA). Third-party cookies were allowed in this experiment for use cases unrelated to targeting, such as frequency capping and measurement.

Google Shares FLEDGE Specification for the First Origin Trials
Just two days after publishing Topics API, Google shared more details about the FLEDGE API specification for the upcoming Origin Trials. It is definitely a positive move, as it improves the industry’s understanding of the scope of tests that will be possible in the upcoming months. The specification includes essential features for advertising efficiency and utility, such as those created by RTB House – Product-level TURTLEDOVE and Outcome-based TURTLEDOVE. Sadly, the testing phase timeline hasn’t been updated for months now, so a more detailed timeline is still unavailable.
