What is WordPress Lazy Loading?

Lazy loading is an optimization strategy that loads visible material in the viewport first and then waits for the stuff below the fold to load and render.

Usually, there are a lot of things that showcase on your website like videos, images, links, and so on. When a user comes to your website, your website takes a lot of time to load due to these many things.

So, what a lazy loading strategy does is that it first loads the assets like images or media that are up the fold and shows them to the user. More assets will be loaded upon user scrolling.

How does WordPress Lazy Loading work?

The DOM (Document Object Model) of the web page is generated by the browser without the need to download graphics or preload multimedia. Then, based on the content that loads first on the website, JavaScript is used to determine which photos and videos to preload first.

This way only those images and videos are preloaded that are visible in the viewport. More videos will not be loaded or rendered until the viewer scrolls down the page to see more content.

For sites with a lot of high-resolution photos and embedded videos, this can result in a significant performance boost.
