Page Speed & Core Web Vitals
How fast and stable a page loads, which affects rankings and conversions.
Page speed is how quickly a page becomes usable, measured in part by Google's Core Web Vitals: loading, interactivity, and visual stability. It is a ranking factor and, more importantly, a conversion factor, since slow pages lose visitors before they ever read a word. Improving it usually means lighter images, less script, and better hosting.
