What is LCP?
Largest Contentful Paint (LCP) measures how long it takes for the largest content element visible in the viewport to render. This is typically an image, video, or large text block. Google considers a good LCP score to be under 2.5 seconds.
Why LCP Matters
LCP is one of the three Core Web Vitals that Google uses as a ranking factor. A poor LCP score can hurt your search rankings and user experience.
Steps to Improve LCP
Optimize Images
Use modern formats like WebP or AVIF, implement lazy loading for below-the-fold images, and serve responsive images with srcset.
Improve Server Response Time
Use a CDN, enable server-side caching, and optimize your backend code to reduce Time to First Byte (TTFB).
Remove Render-Blocking Resources
Inline critical CSS, defer non-critical JavaScript, and preload key resources.
Preload LCP Element
Use <link rel='preload'> to prioritize loading of your LCP element.
