Chrome provides public metrics and tooling for sites and others, like advertisers, to better understand real users' ad experiences and their impact.
Chrome publishes experimental metrics about Chrome users' ad experiences from Chrome users through the Chrome User Experience Report (CrUX). This is reported for eligible sites at an origin and page-level.
