How does the app work?

Page Speed Optimizer uses lightweight, but powerful Javascript to improve your store's page loading times. It does this by feeding information to the browser, based on a user's interaction with your site. There are three general steps involved in the application of this script.

1

The script checks for all links on a page when it first loads.

2

When a user moves their mouse cursor over a link or touches it on a mobile device - even while scrolling - the script tells the browser to begin pre-loading that link in the background. This ensures faster page loading.

3

If a user moves away from the link without clicking it, the script tells the browser to stop preloading that link.

Streaming sites use a similar idea when they play a silent preview of a video as you hover over it on a results page.

This is the reason why testing tools such as GTMetrix or Pingdom will not be able to detect our app's improvements to your site. They are not able to simulate this real-world, user behavior in their tests. Our app helps improve performance on the user's end for an optimal experience of your store.
