What are Core Web Vitals?
Core Web Vitals are Google's measures of how quickly a page loads, how soon it responds to a click or tap, and whether content jumps around. Your results explain which measurements are available.
Does the performance check make changes to my website?
No. The check explains available measurements. Share the result with the person who maintains your website before choosing a fix.
Will every page have performance data?
No. Some pages may not have enough data. Those measurements are marked as unavailable.
