Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) measures loading speed: the time from navigation until the largest visible element — usually the hero image or main heading — finishes rendering. Good is under 2.5 seconds at the 75th percentile of real users. Typical fixes: faster server response, preloading the hero image instead of lazy-loading it, removing render-blocking scripts and styles, and serving properly sized images from a CDN.
