The Chrome User Experience Report (CrUX) provides metrics about how real-world Chrome users experience your website.


Check our Core Web Vitals Explained blog post for more info the importance of CWV.

While the data is gathered directly from real users for the last 12 month, the CrUX data is basically a transposition of Lighthouse metrics in a real world scenario. Also, each chart contains the 75th percentile, so it is easy to see how much you need to work in order to pass CWV.


In some cases, there may not be enough available real user data for your domain. In this case, no credits will be consumed from your resources.


To get the historical CrUX data, be sure to check the checkbox in the snapshot configuration settings.
