Core Web Vitals checker
How fast a page really is for the people who visit it: Google's field data for the page and its site, on phones and on desktops, with one lab run beside it.
WHAT IT READS
- Field data from Google's Chrome UX Report: the 75th percentile of real Chrome visits over Google's 28-day collection period, for the exact page and for its whole site, phone and desktop separately.
- One lab run of the page on Google's servers (a simulated mid-range phone), shown beside the field data and never in its place.
WHAT IT DOES NOT TELL YOU
- A page or site without enough Chrome visits has no field data. We say so, and we never fill the gap with the site's numbers or the lab run's.
- The assessment is Google's thresholds applied to Google's numbers; it is shown only when all three Core Web Vitals have field data.
- Your site itself is not contacted for the field data: it comes from Google.
