The Chrome User Experience Report (also known as the Chrome UX Report, or CrUX
for short) is a dataset that reflects how real-world Chrome users experience
popular destinations on the web.
CrUX is the official dataset of the Web Vitals
program. All user-centric Core Web Vitals metrics are represented.
CrUX data is collected from real browsers around the world, based on certain
browser options which determine
user eligibility. A set of
dimensions and
metrics are collected which allow site owners
to determine how users experience their sites.
The data collected by CrUX is available publicly through a number of
Google tools and third-party tools and is used
by Google Search to inform the
page experience ranking factor.
Not all origins or pages are represented in the dataset. There are separate
eligibility criteria for origins
and pages, primarily that they must
be publicly discoverable and there must be a large enough number of visitors in
order to create a statistically significant dataset.
