Lazy Loading Images Checker

Lazy loading defers loading of offscreen images and iframes until the user scrolls near them. This reduces initial page load time and saves bandwidth for users who don't scroll through the entire page.

When implemented correctly using the native loading="lazy" attribute, lazy loading improves page speed (an SEO factor) without affecting indexation. Google can discover lazy-loaded images.

No. Don't lazy load above-the-fold images (hero images, logos) as this delays their display. Only lazy load images that appear below the initial viewport to improve perceived load time.
