LCP
One of the Core Web Vitals metrics proposed by Google, measuring the time at which the largest content element in the page viewport finishes rendering, used to assess perceived load speed.
Timeline (last 90 days)
The selectable Speed Insights metrics include Real Experience Score, LCP and CLS.
LCP measures the time for the largest content element in the page viewport to finish rendering, and CLS quantifies the degree of unexpected movement of visual elements during page load; both are members of Google's Core Web Vitals system.
The Real Experience Score is the core metric provided by Speed Insights, computed as a score from 0 to 100 based on real user monitoring data that combines Core Web Vitals such as FCP, LCP, FID and CLS.
LCP, INP, and CLS are the three Core Web Vitals metrics in Google Web Vitals, measuring loading speed, interaction responsiveness, and visual stability, respectively.
LCP (Largest Contentful Paint) measures the loading speed of main content, with a target of ≤2.5 seconds
Core Web Vitals currently includes three core dimensions—LCP, INP, and CLS—with ideal values of LCP within 2.5 seconds, INP below 200 milliseconds, and CLS below 0.1.
LCP (Largest Contentful Paint) is the largest contentful paint time, and heavy JavaScript execution delays the rendering of critical content.
Code splitting combined with lazy loading and resource preloading techniques can significantly reduce the FCP and LCP metrics for initial load time.
