More about the Page Speed Insights Preview
Search ranking doesn't care about total page weight directly, it cares about Core Web Vitals specifically, largest contentful paint, interaction responsiveness, and layout shift, the exact metrics Google actually measures and factors into ranking rather than a generic size total. This tool previews an estimated page speed score and those Core Web Vitals for any URL, showing the specific numbers that actually affect search ranking rather than a general performance impression. Useful for checking whether a page's Core Web Vitals actually meet the thresholds Google rewards in ranking, seeing which specific vital, loading, interactivity, or visual stability, is dragging a score down, or comparing an estimated score before and after a performance fix to confirm it actually helped ranking.
