How the benchmark works
The benchmark uses the Chrome User Experience Report (CrUX), Google's public dataset of real Chrome users. All metrics reflect a 28-day rolling window, measured at the 75th percentile.
The UX Score weighs five Web Vitals into a single number out of 100: LCP 25 + INP 25 + CLS 25 + FCP 15 + TTFB 10 = 100 points.
Frequently asked questions
Where does the data come from?
All metrics come from the Chrome User Experience Report (CrUX), Google's public dataset of real Chrome users. Scores reflect a 28-day rolling window, measured at the 75th percentile.
How is the UX Score calculated?
The UX Score combines five Web Vitals into a single number out of 100: LCP 25 + INP 25 + CLS 25 + FCP 15 + TTFB 10 = 100 points. It is computed from CrUX real user data and contains no business metrics.
Why does my site show no data?
CrUX only includes origins and URLs with sufficient traffic from real Chrome users. New sites, low-traffic pages and staging environments typically do not appear in the dataset.
