Lazy Loading

Checks for lazy loading on below-fold images

Rule ID	images/lazy-loading
Category	Images
Scope	Per-page
Severity	info
Weight	3/10

Solution

Use loading=‘lazy’ on images below the fold to defer loading until needed. This improves initial page load and saves bandwidth. Native lazy loading is supported by all modern browsers. Don’t lazy load above-fold images (especially LCP candidates). Consider loading=‘eager’ for critical images.
