Chrome’s Topics API public origin trial to start soon on AdSense
https://support.google.comGoogle calls Topics an evolution of their previous proposal for interest-based targeting which was called FLoC.
From July 1, 2022, AdSense will start initial testing of Topics globally on ad requests for a small percentage of traffic. This initial test is to validate that their systems are operating as designed, and no revenue or performance impact is expected. If you prefer to opt out of Topics testing, you can do so using Chrome’s Permissions-policy header.
