Are you having problems with a slow-loading website? Then perhaps you should consider applying the concept of lazy-loading. It is when content only loads on a page when a user wants it to; specifically when users scroll down on a web page to view that piece of content. As a result, the total size of your website is reduced, allowing it to load at a faster pace than before.
If you have a WordPress website that makes use of high-quality images, videos and photo galleries and wish to reduce its loading speed, then this is the article for you. Fortunately, the WordPress plugin repository has a slew of lazy loading plugins that this article covers for you.
Lazy Load by Mohammad Jangda, relies on jQuery Sonar to view images for users when the images are visible in front of them. The plugin uses this to run Ajax calls to decrease page size and load times for images.
The plugin has been built on a code by Automattic’s WordPress.com VIP team. It might not have a lot of options but it gets the job of fast loading time done.
BJ Lazy Load
BJ Lazy Loud is another popular lazy loading plugin that replaces all of your website and blog’s images, thumbnails, content iframes and gravatar images with a placeholder and only loads content upon user navigation. By working with iframes, the plugin covers embedded videos from YouTube, Facebook, Vimeo and more.
The plugin is also compatible with the RICG Responsive Images plugin to optimize images to be responsive.
Many WordPress users use this plugin because it is easy to setup, customize, supports dynamic embeds and CDN-powered images. BJ Lazy Load is also very clean and won’t affect user experience.
