Google plans to update its algorithm in May 2021 to include a factor called Page Experience. This includes existing Google Search signals such as mobile-friendliness, safe-browsing, HTTPS, and intrusive interstitial guidelines.
At the forefront, it includes metrics in Google’s Web Vitals to do with a site’s loading speed, interactivity, and visual stability.
