What is LCP (Largest Contentful Paint)?
LCP is the time until the largest visible element (usually the hero image or H1) appears on screen — target: < 2.5s.
LCP (Largest Contentful Paint) is one of the 3 Core Web Vitals. It measures perceived loading — what matters is not "page loaded" but "user sees something useful".
Biggest culprits: hero image without priority/wrong lazy, fonts blocking render, JavaScript hydrating before paint. Fixes: image preload, fonts with display:swap, aggressive code-splitting.

Frequently asked questions
Why is my LCP 4s even on a fast site?
Likely hero image not preloaded or fonts blocking. Check PageSpeed Insights for the culprit element.
Does LCP only count on mobile?
Google measures both, but mobile-first indexing prioritizes mobile. Optimize for mobile first.
