Previous Question Next Question

Lazy-loading images can significantly improve both Largest Contentful Paint (LCP) and overall page speed by deferring the loading of non-critical images until they are needed. This reduces initial load times and improves user experience, especially on slower connections.

Example Concept: Lazy-loading is a technique that delays the loading of images until they are about to enter the viewport. By using the "loading='lazy'" attribute in the tag, browsers can prioritize critical resources and improve metrics like LCP by reducing the amount of data processed during the initial page load.

Additional Comment:

Lazy-loading is particularly effective for pages with many images, as it reduces the initial payload.
Ensure that images critical to LCP are not lazy-loaded to prevent delays in rendering the largest visible element.
Modern browsers support native lazy-loading, making it easy to implement without additional JavaScript libraries.
Always test the impact of lazy-loading on different devices and network conditions to ensure optimal performance.
