“Lazy Loading” is a technique that helps the important parts of your site load quickly for visitors.
Lazy Loading makes sure that page elements that are non-critical will load after the more important elements.
Imagine you open an article you want to read on the internet. Usually, you would start at the title and perhaps eventually read down to the comments. It makes perfect sense to load the title first and then load the comments later.
This technique can also apply to videos and images. Theses can be large elements, and often it's not necessary to display them immediately. Lazy Loading can ensure that you pull the video and image data only just before the element appears on the screen.
By default, WordPress loads the comments automatically. Lazy loading comments, particularly on posts with a big amount of comments (200-300), can improve your site performance. WordPress can load the title and body of the post and then load the comments later.
The Lazy Load for Comments plugin for WordPress prevents WordPress from displaying comments automatically and loads them on request.
