I just started using this app for my store and it helped a little bit with page speed but it didnt perform as I expected it to.Still its better having it than not having it in the end.

I don't really what has it done. It was only one click, 1 second and says the page is faster? Well...

Hi there,

Not a big fan of the swearing, but I understand that you might have been frustrated using the app for some reason.

More than happy to help dig into any issues you may have had if you'd like to share?

It does not reduce the loading time of the first page web visited by the client, what it does is make it worse.

Most times a user does not get to enter the web since the web is slow and takes time to load. What happens with this APP is that it loads its code on the first page that a user visits so the loading time increases and there is more probability that the client will never come to visit us. Apparently, when you have already entered, if you browse the web, it loads faster because the links are preloaded. In my opinion I prefer to look for another one that improves the loading time of the first page you visit.

You can check from the official google links to measure time, both in mobile version and in computer version:

I'm not sure it worked, do I need to wait for a period of time before checking the speed? I checked before and after and the score had got worse rather than better!

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.

My website run very slow, i have downloaded this app from the app store because i read that it really helps to make the website load faster, unfortunately it didn't help and my website still running very slow.
there is no option to contact any one in this app who can really help, no contact info no costumer support.
I don't understand how this app has 779 reviews 4.8 Rated.. something is wrong here.,,

Hi there, sorry we let you down here. Some themes already include our speed optimization code. As a result, these themes wouldn't see any increase in speed. Cheers, Stuart

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.

Does not work in the theme by Out of the Sandbox. After turning on, all images disappeared, and when off they came back.

Support just blamed everyone else and didn't even have a look. First it was domain provider, then it was Shopify and then heavily optimised theme (it really isn't) - just guessing.
