Third-party cookies use people’s browsing history to target ads that then follow them from site to site. Google’s “indecision” over what system it wants to replace cookies has been criticised by some in the ad industry. It comes as the technology giant said an interest-based user-tracking system, Topics, would now replace its earlier proposal, Federated Learning of Cohorts . And Google has agreed to restrict their number on websites accessed via its Chrome browser, which commands about 65% of market share. Google confirmed Floc would now be replaced by Topics, a similar system that would group users in topic clusters, selected out of about 350 categories such as fitness or travel. Do ypu think that this is a change in advertising policy ?
