LCP (Largest Contentful Paint) is a Core Web Vitals metric by Google that measures loading performance.

  • It tracks how long it takes for the largest visible element (like an image, video, or text block) to render on the screen.
  • A good LCP score is 2.5 seconds or less.
  • Affects both user experience and SEO rankings, since faster-loading pages keep users engaged.

👉 Common fixes for poor LCP include optimizing images, using a CDN, improving server response times, and reducing render-blocking resources.
