What is Largest Contentful Paint?
Largest Contentful Paint (LCP) is a Core Web Vitals metric that measures when the largest content element on a page — usually a hero image or big heading — becomes visible. It represents the moment users feel the page has loaded.
Why LCP matters
LCP is a direct ranking factor. A slow LCP means visitors stare at blank space, which destroys engagement and conversion. It is the most commonly failed Core Web Vital and the biggest lever for page experience.
How to improve LCP
- Optimize and compress hero images; use modern formats.
- Reduce server response time (TTFB) with caching and a CDN.
- Remove render-blocking CSS and JavaScript.
- Preload critical images and fonts.
Target
Google’s threshold for ‘good’ LCP is under 2.5 seconds.
