Page speed is becoming more and more important each day. The latest version of Google Chrome mobile (version 85 currently in beta) will now start labeling a link as a "Fast Page" if it is indeed fast by Google's standards.
The feature will work something like this :
Google Chrome analyzes the historical Core Web Vitals metrics to label a link as fast.
Core Web Vitals of a page can be found from Google PageSpeed Insights.
The user, knowing that some of the navigated links may turn out to be slow, may choose not to open those links.
Apart from using page speed as a ranking factor in Google search, it is slowly being extended as an inbuilt feature in the most popular browser.
Good news for end users as they will have a better web experience. But a stressful news for web developers and site admins as they will need to work on page performance. It seems only the fittest pages will survive the internet.
