Extended definition

Time until the largest visible element on the page loads. Target: under 2.5 seconds.

Context and application

LCP measures when the user sees “main content” — usually the hero image on landing pages or the first paragraph on blog articles. Common optimization tactics: fetchpriority="high" on the LCP image, preload font display:swap, eliminate render-blocking CSS, lazy load ALL below-fold images (loading=“lazy”). On WordPress sites, cache plugins (LiteSpeed Cache, WP Rocket) automate most of these optimizations. Common myth: “LCP is about TTFB”. Wrong — TTFB is just the server component. LCP also includes client-side render time.

In practice

optimize hero images, fonts, render-blocking JS.
