Previous Question Next Question

Lazy-loading images can significantly improve your page's Largest Contentful Paint (LCP) and overall performance by deferring the loading of non-essential images until they are needed. This reduces initial load time and resource consumption.

Example Concept: Lazy-loading delays the loading of images that are not immediately visible in the viewport, allowing the browser to prioritize critical resources and improve initial rendering speed. This technique helps in reducing the time to LCP by ensuring that only the most important images are loaded first, thereby enhancing user experience and page performance.

Additional Comment:

Use the "loading='lazy'" attribute on img tags to enable native lazy-loading in modern browsers.
Ensure that critical images, especially those above the fold, are not lazy-loaded to avoid delays in LCP.
Test your page with tools like Lighthouse to verify improvements in LCP and overall performance.
Consider using a placeholder or low-quality image preview to maintain visual stability while images load.
