I haven't yet used the app... I am just verifying my store and they asked if I could give them a review. They have been very helpful so far so 4 out of 5 is where its at currently.

buena aplicación hace lo que dice, aumenta la velocidad de la pagina una vez ya has entrado en ella y vuelves a ella, no en la carga inicial .

slight difference, my speed for mobile increased from 6 to 9 and desktop from 36 to 40, so that is not a big difference unfortunately.

Hi there, thanks for the review. You are absolutely correct, the app will not show any increase or decrease in GTmetrix or any other tool.

From our FAQ on the dashboard of the app:

Important Notice:
This app will not increase or decrease any pageload speed metrics such as Pingdom or Gmetrix. The app preloads links, which only works from the second page view. These apps DO NOT account for second page load times in their results.

The app utilizes open source software ( to preload links on your theme, thus speeding up loading times after the first page load.

As mentioned throughout the app, some themes already include this open source code by default. As a result, these themes wouldn't see any increase in speed because the code is already present.

This app does what it says even though Shopify still says my store is slow. After the first page clicking through my site is faster.
