How can I improve LCP on mobile devices?
Asked on Dec 06, 2025
Answer
Improving Largest Contentful Paint (LCP) on mobile devices involves optimizing the loading of the largest visible elements on the page, such as images or text blocks, to ensure they render quickly. This can be achieved by addressing factors like server response times, resource loading, and client-side rendering.
Example Concept: LCP measures how quickly the largest visible content element loads and becomes visible to the user. To improve LCP, prioritize loading critical resources, use efficient caching strategies, and minimize render-blocking resources. Techniques include optimizing images, using a content delivery network (CDN), and deferring non-essential JavaScript.
Additional Comment:
- Optimize images by using modern formats like WebP and compressing them effectively.
- Implement lazy loading for offscreen images and iframes to reduce initial load time.
- Use server-side rendering (SSR) for faster initial content delivery.
- Minimize CSS and JavaScript to reduce blocking time during page load.
- Ensure your server response times are under 200ms for optimal performance.
