Full Explanation
Chrome User Experience Report (CrUX) is a public dataset that provides real-world user experience metrics collected from Chrome browsers (with user consent). CrUX data powers the field data in PageSpeed Insights and is what Google uses for Core Web Vitals ranking signals. Unlike lab data from Lighthouse, CrUX represents actual user experiences across diverse devices and network conditions. CrUX reports metrics at the 75th percentile, meaning 75% of user experiences must meet the threshold to pass. You can access CrUX data via PageSpeed Insights, Search Console, or BigQuery. CrUX is updated monthly.
