Largest Contentful Paint (LCP) is a core metric that measures the time it takes for the largest visible content element on a webpage to load. This could be an image, video, or block of text that dominates the viewport. An ideal LCP score is under 2.5 seconds, indicating a smooth user experience. LCP focuses on perceived loading speed, unlike other metrics that track behind-the-scenes processes. Optimizing LCP involves enhancing server response times, optimizing resources, and improving CSS and JavaScript delivery.
