optimiza la página muy bien y va super rápido. La carga a la tienda también es bastante más efectiva, en definitiva una aplicación bastante buena.

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.

I had a very positive chat with Lester just now! I have started using the app and it is fixing my alt tags for me. I am planning to use Pro after my 24 hour free trial.
So far the App seems brilliant - no problems, and the fact that it does things automatically is really great!
Maybe 5 stars hen I have used it a bit!

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.
