, the Product Director for Privacy Sandbox at Chrome, the initiative is aimed at improving web privacy for users while giving publishers, creators, and other developers the tools they need to build thriving businesses while ensuring a safe and healthy web for all. They are aware that online advertising is critical for many businesses and it is key to support access to free content online.
With this feature, websites would only show ads based on the topics identified by your browser without needing to know exactly which websites you’ve visited previously. In other words, it is your browser that decides what ads are shown to you. To identify topics that are of interest to you, Chrome uses the mapping of websites and subdomains to the topic.
Since Topics is browser-based and not linked to your personal identity, it is possible for a user to get served different ads on their smartphone, tablet, and computer. For example, if you’ve searched for hotels only on your smartphone, you shouldn’t get travel-related ads on your other devices.Besides Topics, Google also has FLEDGE which allows advertisers to run remarketing and custom audience ads.
