What is Lazy Loading

No, lazy loading is not when delivery drivers carelessly throw your packages into the truck.

It is an optimization technique that is widely used in the advertising industry. Normally when a page is loaded, the entire page is downloaded and rendered at that time.

This includes content above the fold, and below the fold as well, meaning content that is immediately within the window as well as the out of view which requires the user to scroll. 

Let’s explore this optimization solution, maybe it can benefit your site as well.


Why is it used?

Lazy loading is widely used today as there are many benefits to it.

The most obvious goal is to reduce the initial load time when loading a site.

Studies have shown that 53% of mobile users abandon pages if it takes longer than 3 seconds to load.

With the implementation of lazy loading, you can ensure that the page, or at least the initial viewable portion will be rendered for the user in as little time as possible. 

Another benefit that lazy loading can bring to the table is bandwidth conservation.

Lazy loading can conserve processing and latency bandwidth by delivering content only when it is requested.

This helps out both the server as well as client resources. 

With all these points in mind, is it good to implement lazy loading for all the content on your page?

Well, this is dependent on each specific case.

If your site is densely packed with images and videos, it would be beneficial to apply lazy loading to these aspects.

If the page contains a very long article, or trying to implement an infinite scroll experience, this may be a good use case as well.


How does PubGenius do it?

Specifically here at pubGENIUS, we place user experience in high regard, and we apply this to a lot when optimizing our partner sites.

The technique is only applied when necessary, for instance, ad units at the bottom of a page.

If implemented correctly, it can increase the user experience of the site making it more attractive for viewers to return.


Conclusion

Lazy loading is a great way to increase page load time, conserve bandwidth, and increase overall user experience.
