FMP (First Meaningful Paint)
First Meaningful Paint (FMP) was a performance metric that measured when the primary above-the-fold content becomes visible to the user — specifically the "hero" element of the page. Originally included in Google Lighthouse, FMP was deprecated in Lighthouse 6.0 in favor of Largest Contentful Paint (LCP), which is more reliable and correlates better with user experience.
Though deprecated from Lighthouse, FMP data was historically collected via Chrome DevTools and lab testing tools. Today, its function is largely replaced by LCP in Google Search Console's Core Web Vitals report and PageSpeed Insights, which measure the render time of the largest visible element.
