What is LCP (Largest Contentful Paint)?
Turkish: LCP
LCP is a Core Web Vitals metric measuring the time for the largest visible content element to appear; under 2.5s is considered good.
What is LCP?
LCP (Largest Contentful Paint) measures when the largest visible content element appears in the user’s viewport. On many pages this is the hero image, main heading block, banner, or product image, so it strongly affects whether the page feels loaded.
LCP is influenced by server response time, HTML parsing, render-blocking CSS and JavaScript, image size, font loading, and lazy-loading decisions. In Google’s Core Web Vitals assessment, 2.5 seconds or less is good, while more than 4 seconds is poor. Both lab tests and real-user data matter; a single Lighthouse run does not represent all traffic.
How to Improve It
- Load the hero image at the right size, in a modern format, with high priority
- Deliver critical CSS early and defer unnecessary JavaScript
- Reduce startup delay with CDN, caching, and fast server responses
- Identify the LCP element and avoid delaying it with animations or lazy loading
LCP is one of the three primary user-experience metrics in Core Web Vitals. Its SEO relevance belongs in technical SEO, while practical fixes often involve image optimization and frontend performance decisions.
