Google abandons FLoC, introduces Topics API to replace tracking cookies
Google is walking back plans to replace third-party cookies with FLoC by instead proposing the Topics API, a new system for interest-based advertising. Topics works by pinpointing five of your interests, such as "Fitness" or "Travel & Transportation," based on your web activity, as measured by participating sites, for one week.
