Your summary is generated based on Google’s Chrome User Experience Report (CrUX)—a public dataset of real user experiences for millions of websites. CrUX collects data only for Chrome browser users who opted in (excluding devices with the iOS operating system). The set is updated daily and aggregates the previous 28 days of data.
The Core Web Vitals Assessment section shows if your page or site passes Core Web Vitals assessment. The 75th percentile means that 75% of recordings were lower than showcased Web Vitals values (e.g. 75% of page or site visitors had Largest Contentful Paint of 2.5s or less).
The overall values are categorised as good, to improve or poor. Below, with a breakdown of each metric performance, you can see the percentage of good and poor user experiences and determine where you should make improvements.
Your site has to have enough traffic to be included in the CrUX report. New sites are added to the dataset every day, so keep checking in the future or try running a report on the entire domain. In the meantime, you can also monitor Core Web Vitals in Calibre!
