This app has been super helpful in improving my page speed. It improved from 60 to 80's. I can't get to the 90's due to my own selection of apps, but Tonny was very helpful in providing help and advice. This isn't a one time service deal, Tonny is always available to provide insight and help where he can even months after the service. Absolutely recommend!



My page is speed is up over 90 now thanks to tonny and he was very helpful over emails in getting it all working 100%, The app just made my desktop menu not go full screen and tonny fixed that and personally went over my website and speed it all up. Thanks heeps

Can't recommend this app enough! We were dealing with quite a bit of bloat after a previous web dev worked on the site, and Tonny did an amazing job optimizing our everything - even doing another optimization after we installed some additional apps which slowed the site down again. He even gave some suggestions and best practices on how to keep our site running smoothly. Currently running at 85/87!

If you're on the fence on trying this out, don't be - make a backup of your theme and give it a try, you'll be glad you did!

How is it done

PageSpeed Guru speeds up your shop by removing renderblocking caused by stylesheets and scripts.

  1. PageSpeed Guru inlines your CSS.

  2. Depending on your shop, the theme, your apps and how your shop is set up. PageSpeed Guru tries to:

    • Load your scripts with ASYNC
    • If that doesn't work (re: happens when scripts have interdependencies) it tries to load you scripts with DEFER.
    • If a and b doesn't work it inlines javascript (re: this always works) but is uggly.

Since each lookup of an external ressource like CSS and javascript can take anywhere from 0.1 second to several seconds. Removing renderblocking will always speed up your shop.

** If you have 10 stylesheets you have a minimum gain of 10x0.1 ~ 1 second. and so on.**

I installed this product 24 hours ago and it made my website constantly crash - I have emailed support about 5 times for a refund as I was only able to use it for 24 hours or less I haven't heard anything from them, will be raising this is with the Shopify app's team next


This is a great app! It took my pagespeed scores from the 60s to the 90s! I highly recommend it! The support is really great as well. I had a minor question, and they answered it right away, and helped me out. Really first class.


Awesome App to have. You might not be able to see the "increase pagespeed" button when you have changed theme..

He edited my site and made it worst and caused glitching on the site, I had to rewind back to before he did work on it, Not recommended


After running the app on one of our sites, the speed improved by 10 points, but the mobile menu started showing by default on both mobile and desktop views. And the user is not able to close out of the window. So most of the screen on mobile was covered by the menu.

After running the app on our other site, the speed went down fro 82/100 to 80/100.


Great app, does exactly what it is supposed to do


No. I have a few stores and used this on all my stores. It took my page speed from 68 to 70 for $29. That is barely an increase. I have seen it do a much better job on all of my other stores.


Works sometimes, sometimes not. Just freezes in the processing mode (and no, I have been waiting for 24 hours sometimes without closing it and still same issue).

When it works however, speeds up the site quite a bit.


It really works in my store every store should try it


Sorry, guys,
you ruined my whole layout and also my CSS. I have used now an IT Company to set up my store new. We add some extra stuff for the German government for our German law and now this set up is gone. I need as soon as possible help from your support.
