Speed is key on the Internet. Whether you want more conversions, more search traffic, or more satisfied users, it pays to optimize your WordPress site for speed.
The average web pages weight in at 1820 kB with images and videos making up nearly 73% of the total weight according to the HTTP Archive. That’s a lot of bytes for a website visitor’s browser to download and render, and the trends all point to larger web pages and increased used of images in the future. WordPress is leading the charge when it comes to sharing media and incorporating media files into the site design. With WordPress it’s easy to integrate images and videos into posts, pages, and even into the background of the theme.
However, all those heavy resources make downloading a web page a costly experience as users that have to wait for large files to download — including files that aren’t initially visible — before viewing a web page. This is where WordPress lazy load comes into the picture. Lazy loading is an optimization technique that loads visible content but delays the downloading and rendering of content that appears below the fold. It’s just the sort of thing.
It’s just the sort of thing Google gets excited about, and it’s a technique you should consider if your posts and pages include a lot of embedded videos and high-resolution images.
How Does Lazy Loading Work?
Lazy loading works like this:
- The browser builds the web page DOM without downloading images and preloading videos.
- Downloading and rendering of additional videos are delayed until a site visitor scrolls down the page and additional content comes into view.
The end result is that images aren’t downloaded and videos loaded until they are actually needed. This can provide a significant boost in performance for sites that include a lot of high-resolution images and embedded videos.
