Experience metrics to be used in rankings.
Google is going to start using “Core Web Vitals” as a ranking signal for websites.
Core Web Vitals measure critical aspects of the user experience. These include load time, interactivity, and the stability of content as it loads.
Google said the changes wouldn’t happen until at least next year, and the company will give six-months’ notice.
It’s worth noting that Google uses hundreds of signals to determine rankings. It will always prioritize good content over things like Core Web Vitals. The company noted:
While all of the components of page experience are important, we will prioritize pages with the best information overall, even if some aspects of page experience are subpar. A good page experience doesn’t override having great, relevant content. However, in cases where there are multiple pages that have similar content, page experience becomes much more important for visibility in Search.
I’ve found that much of the concern over penalizing sites that are not mobile-friendly was overblown. You can expect the addition of this new signal to be modest at first.
