What is Site speed test and what is it for?
Measures a page's loading performance: time to first byte (TTFB), first contentful paint (FCP), total load time, request count and page size. Page speed is not just user experience; it is a metric that affects search ranking, and mobile results in particular can come out noticeably lower than desktop.
