Understanding lazy loading impacts on WordPress and WooCommerce

Isn’t it annoying when a web page takes forever to load? And so, the next thing you do is to hit the close button on that page. Everyone needs things to work out in a short time. A slow-loading website can cost you traffic, conversions, and customers.

What is Lazy Loading?

Every website visitor expects a web page to load in a snap second. You should continue to look for methods to optimize page load times, and lazy loading is one of them. Let’s have a look at what lazy loading is all about.

Creating a website involves adding several images or videos to your page. These large files take a long time to load which can slow down your site.

Lazy loading is an optimization technique that delays the rendering and loading of content below the fold while loading visible content. So, the lazy loading feature ensures that images only load when they are viewed on the user’s browser.

For example, on a website with 10 photos, only the first few will load instantly, with the remaining loading as the user scrolls down the page. As a result, the initial page load time is considerably reduced, boosting the user experience. Delaying the rest of the images on a webpage saves storage space and eliminates unnecessary code execution.

When dealing with a large number of products, the default configuration might cause performance issues because all matching products are downloaded from the database and formatted by the plugin. This might cause slower page load time and, in the case of particularly large product databases, may even result in a website crash, server, or database error while attempting to load the table.

For such cases, you can make use of the lazy load feature to avoid any performance issues. Lazy load uses AJAX to load one WooCommerce product page at a time.

How does Lazy Loading impact SEO & performance?

Drawbacks of lazy loading for SEO:
