CrUX

Also known as: Chrome User Experience Report

Aggregated experience data from eligible Chrome users on real websites.

A practical example

A report shows the distribution of website loading quality.

What should I know?

A low-traffic URL may lack enough data for its own report.

Performance and UX in practice

Assess real users' experiences on their devices. Lab tests help identify causes, while user data shows the scale of a problem. A good website also makes information easy to find and tasks easy to complete.
