PageSpeed

Track site speed with real user (CrUX) data and catch improvements and regressions early.

Live Performance Test

The other tabs read the historical field data Google has collected; this one tests your page RIGHT NOW. Our engine connects to the site, runs the speed checks, and brings the current CrUX data and the PageSpeed lab measurement together on one screen. It's the fastest way to see the effect of a change you've just made.

To get started, enter your site address above and press Run Test.

An instant measurement

Deployment verification

Confirm within minutes whether the optimization you shipped actually worked.

This data refreshes weekly. CrUX updates the 28-day experience of Chrome users once a week. Sign up and this data is fetched automatically every week for your registered sites; speed-up and slowdown events, and how they correlate with your Google rankings, are tracked in the Core Web Vitals section of your panel.
