What is Largest Contentful Paint (LCP)?
A Core Web Vital that measures how long it takes for the largest visible content element on a page (usually a hero image or headline) to render. Google considers LCP "good" under 2.5 seconds.
Pages with LCP over 4 seconds typically trigger a mobile ranking penalty. Most LCP problems come from oversized, unoptimized hero images. Compressing images to under 200KB and serving them at the right dimensions is the most common fix.
