Plugin: lazy-load-for-images (Used by 16 domains)

Smart LazyLoad is a fast, lightweight, and SEO-friendly lazy loading plugin for WordPress. It improves page speed and Core Web Vitals by loading images, iframes, videos, and background images only when they are about to enter the viewport.

Built with pure JavaScript, Smart Lazy Load does not rely on jQuery or other third-party libraries, keeping your site fast and bloat-free.
