What is a good LCP score?

LCP (Largest Contentful Paint) is a metric that measures the loading performance of a webpage by determining the time it takes for the largest content element on the page to be fully rendered. A good LCP score is one that is under 2.5 seconds, as this is the threshold recommended by Google for providing a good user experience. However, it is worth noting that LCP score is just one of the Core Web Vitals metrics, and a good user experience depends on a combination of good scores on all the Core Web Vitals metrics. Additionally, LCP is not the only performance metric that affect user experience and SEO, other performance metric such as TTFB (time to first byte) and the overall size of the page also play a role.
