Are you looking to improve the page load speed of your WordPress site? Increasing site speed will improve search engine rankings, and more importantly, improve user experience.

Content can make your site heavy and slow to load in browsers. Site content consists of comments, images, videos and scripts. Since these are usually large files, optimizing them will greatly affect your site’s speed.

What is lazy loading and how does it work?

Lazy loading means loading content only to the visible part of the browser. This delays the loading of content that appears at the bottom and invisible part of the browser.

Lazy loading will not load images and videos on your web page at the same time. The ones at the top of the web page will be loaded and displayed. Whereas those below the browser’s viewport will linger until the user scrolls down to that point on the page. As a result, images and videos will not download until the user needs it.

Importance of lazy loading

The main goal of lazy loading is to improve the speed of the website.

Site visitors can start using your site without waiting for all images and videos to be fully loaded. This saves visitors time and media download resources that they may not need in the long run.

Lazy loading also saves your site’s resources as you don’t have to submit images and videos until you need to.

Implementing Lazy Loading

There are several plugins for implementing lazy loading. I’ll show you how to enable lazy loading using one of the most popular and easy-to-use plugins for this purpose, A3 Lazy Load.
