This article aims to complete the round of quality tests performed on the sampled Seller-Defined Audiences signals we received from the sell side. While the previous article investigated contextual SDAs, this one will focus on user SDAs and verify how they reflect reality. The tests in this section varied from the ones performed on the contextual signals as the nature of the user type differs. The first test relied on a manual check of an assignment mechanism, while the second one was based on a survey campaign.

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.

The testing season of cookieless tools has started with the announcement of Origin Trials for the Privacy Sandbox proposals. Adtech is now filled with various opportunities for testing – contextual targeting, identity solutions, first-party publisher’s audience data, or group-based methods. It is high time to leave feedback about specific tools in the places where it matters.

It might have been delayed, but the end of third-party tracking cookies is coming at the beginning of 2025, and businesses can’t afford to keep pretending otherwise. The good news is that thanks to this delay, there is still a small window of opportunity for companies to prepare for the cookieless future by engaging with the Google Chrome Privacy Sandbox.

The digital world is a complex ecosystem designed to simplify access to information and help people connect easier with fewer limitations. While not paying for it directly, we need to remember that apart from being a content platform, the Internet is also an enormous marketplace, where we – as users – are clients.
