Google Chrome will evaluate the core web vitals

core web vitals

I see a lot of folks in the industry misunderstanding around core web vitals

Google uses real Chrome usage data to bring in data around the core web vitals about specific pages.

A misunderstanding

Googlebot crawls the web and brings in most of the signals Google uses to rank your pages, but the core web vitals do not come from Googlebot or crawling, it comes from the Chrome CRuX field data report.

You can learn more about the Chrome user experience report if you like.

What John Mueller, the Senior Webmaster Trends Analyst at Google, says at Twitter

Googlebot doesn't evaluate the core web vitals -- we use field data for that. Also, we don't use it yet -- it's planned for the future.

See the Twitter conversation

In May 2021 Google has planned another update where using Page Experience will be rolled out. (mobile friendliness, safe browsing, HTTPS Security and intrusive interstitials as core web vitals)

All the best,
