Chrome UX Report field data (real users)

This page explains what this scan check measures. It is not legal advice or a compliance verdict.

What this check is

This check looks for Chrome UX Report (CrUX) field data covering real-user Core Web Vitals for the origin or URL when available.

Why WordPress sites show it

Field data lags deploys and needs enough traffic. Many low-traffic WordPress sites simply have no CrUX row yet.

Realistic impact

When available, field data reflects recent real visitors rather than a single lab run. Missing data usually means the source lacks enough eligible samples for this URL or origin; it does not mean the site failed.

How to verify a fix

After a sustained period of traffic on the improved page, re-check whether CrUX field metrics are present and updated.
