Google achieves 95% of the conversions per dollar spent using FLoC
Google tested FLoC using Google Audiences. Google says advertisers can expect to see at least 95% of the conversions per dollar spent when compared to cookie-based advertising.
Google this month announced that tests using FLoC provide a similar return on ad investment of cookie-based advertising.
This is possible using Federated Learning of Cohorts (FLoC), a project from The Privacy Sandbox, Google's initiative to eliminate cookies in Chrome until the year 2022.
