What is Lazy Load in Magento for?

Lazy loading or on-demand loading is an optimization technique to defer offscreen objects’ loading (e.g. images) until they appear in the browser’s viewport.

It means when users open the page they have only first-screen content loaded, but the rest media files load only if users access them.

The Magento stores usually have large catalogs full of images that require a lot of time to be rendered. Therefore, the lazy load functionality is extremely useful in such cases to avoid customers’ leaving because of a long time waiting.


What is included in the extension’s lazy load functionality?

The standard functionality of the Google Page Speed Optimizer extension allows not only to enable lazy loading for images but also to choose the most suitable strategy from 4 available. The module makes it possible to preload images for the first screen and specify their exact quantity.

Moreover, you can flexibly adjust custom lazy load options for certain pages and pages’ categories if needed:

  • Home Page
  • Category Pages
  • Product Pages
  • CMS pages

What benefits do you get with lazy load enabled?


Rank higher on Google search

Ensure a fast and smooth
catalog browsing process


Decrease website bounce rate

TIP: You can quickly test your website using the PageSpeed Insights tool to know its score and get the report with the description of weak points of your website performance and suggestions on how to improve them.
