How can I optimize image loading to improve my site's LCP score?

Answer

Optimizing image loading is crucial for improving your site's Largest Contentful Paint (LCP) score, which measures how quickly the largest visible content element loads. Implementing lazy loading and using modern image formats can significantly enhance performance.

<!-- BEGIN COPY / PASTE -->
    <img src="image.webp" alt="Description" loading="lazy" width="600" height="400">
    <!-- END COPY / PASTE -->

Additional Comment:

Use the "loading='lazy'" attribute to defer off-screen images until the user scrolls near them.
Convert images to modern formats like WebP or AVIF for better compression and quality.
Ensure images have defined width and height to prevent layout shifts, improving CLS.
Consider using responsive images with the "srcset" attribute for different device resolutions.
Utilize a Content Delivery Network (CDN) to serve images faster from locations closer to users.
