Google decides whether a site gets the label based on metrics from Core Web Vitals, an initiative it launched earlier this year that helps site owners measure factors such as loading times, responsiveness, and the stability of content as it loads, allowing them to make improvements where needed.
Those sites that have met or exceeded all metrics thresholds for the Core Web Vitals will be awarded the Fast page badge. It appears when long-pressing on a link, which brings up the context menu containing copying, sharing, and so on. The label indicates that “most users navigating to [that site] have a particularly good experience,” and appears alongside a blue tick.
