As previously reported, this signal will combine Core Web Vitals metrics and existing UX signals to provide a holistic view of the quality of the user experience on a web page.
Google announced a new signal in May this year. At that time, it was said that it would be launched in 2021, but no specific dates were specified. Now they have become famous.
According to the official Google documentation, Page Experience is a set of signals that show how users perceive interaction with a page beyond its informational value.
This signal brings together Core Web Vitals (a set of metrics that measure user experience on a page based on criteria such as loading efficiency, interactivity, and visual stability) and metrics such as mobile usability, Safe Browsing, HTTP, and intrusive interstitial recommendations.
