Your questions answered

Where does this data come from?

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.

How do I read this report?

The Core Web Vitals Assessment section shows if your page or site passes Core Web Vitals assessment. The 75^th 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.

Why is there no data for my site?

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!

How do Core Web Vitals impact SEO?

Google evaluates pages based on content, relevance, quality, engagement metrics and many other factors. Core Web Vitals are a page ranking signal for your pages. To maximise website performance and outrank competitors, ensure all Core Web Vitals meet the recommended thresholds for a superior user experience.

How can I improve Core Web Vitals?

There are numerous ways to improve Core Web Vitals. The best way is to continuously monitor site speed (with tools like Calibre) and follow actionable advice tailored to your context.
