See how quickly your site has loaded for real Chrome users over the past nine months, on phones and computers, measured against Google’s Core Web Vitals.
Uses Google’s public Chrome UX Report data, updated every week.
How this works
The data comes from the Chrome UX Report: anonymous timings from real Chrome users who share usage statistics, published by Google.
Each point covers 28 days of visits, and a new point is added every week.
Values are the 75th percentile: three in four visits were at least this fast. That’s how Google judges Core Web Vitals.
Sites need steady traffic to appear. For a one-off lab test, use the website health check.
