If your site does not call document.interestCohort() or include ads, Chrome will already not consider your site in computing FLoC: A page visit will be included in the browser's FLoC calculation if document.interestCohort() is used on the page. During the current FLoC origin trial, a page will also be included in the calculation if Chrome detects that the page load ads or ads-related resources. -- https://web.dev/floc/ https://web.dev/floc/ Detecting "ads or ads-related resources" uses a filter derived from EasyList: https://github.com/chromium/chromium-ads-detection/blob/master/third_party/filter_lists/9.22.0/filter_list https://github.com/chromium/chromium-ads-detection/blob/mast...
