Page Experience (Google)
Page Experience is a set of factors that Google considers important in measuring user experience on a web page.
These include Core Web Vitals (page loading speed, responsiveness to user interactions, visual stability during loading), but also safe navigation, accessibility from mobile devices, and the absence of intrusive interstials.
These indicators are used by Google’s ranking systems to evaluate pages for ranking in the SERPs, and thus Page Experience is essentially a set of key metrics to refer to in order to ensure that people using Web sites, pages, and applications receive the best possible experience, evaluated on the basis of certain metrics and measurements.
