Largest Contentful Paint (LCP) is one of Google’s three Core Web Vitals metrics, measuring how long it takes for the largest visible element on a page — typically a hero image, video, or large block of text — to fully render after a user begins loading the page.
Google considers an LCP of 2.5 seconds or faster to be a good user experience. Slower LCP times are commonly caused by large, unoptimized images, render-blocking JavaScript and CSS, slow server response times, or a lack of proper resource preloading.
Improving LCP often involves compressing and properly sizing images, using a content delivery network (CDN), eliminating render-blocking resources, and prioritizing the loading of above-the-fold content over less critical page elements.
LCP optimization is a specific focus within our Technical SEO service.
