Largest Contentful Paint (LCP) is a Core Web Vital that measures the time it takes for the largest visible content element (usually an image or text block) on a page to load. Google's threshold for a "Good" LCP is under 2.5 seconds. A poor LCP is typically caused by slow server response times, render-blocking JavaScript, slow image loading, or client-side rendering delays.
