Why does Google PageSpeed Insights doesn't show the Core Web Vitals for all websites?


For this website (https://i.sstatic.net/l56Wf.png) pagspeed insights is showing the Core Web Vitals option.

But for this website (https://i.sstatic.net/jTNOO.png) pagspeed insights is not showing the Core Web Vitals option.

I want to know Why?

I am searching for the answer on the internet but I didn't find a satisfactory answer yet.


Solution

  • Core Web Vitals data in PageSpeed Insights is powered by the Chrome UX Report dataset. The linked documentation talks about the eligibility criteria for a single page or whole website to be included, in particular that it needs to be sufficiently popular and publicly discoverable.
