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.**

The app was having issues to optimize my theme so I emailed the devs. Tonny was amazing. He took my store from 60+ to the high 90s both desk top and mobile in the page speed test. Gtmetrix almost 90. It is worth the cost of the app? Totally. I paid another guy in fiverr $70 usd for another theme and he didn't do half good as Tonny. If you have trouble with the app send them an email before ranting here! Me personally, I had a very good experience.


No Optimization for desktop. No disclaimer in the app description that it will only optimize mobile version. Prety much useless as Shopify engine is already optimizing mobile versions pretty good by default.


Ok so I was a pain in the a** at first I'm sure. But, Tonny was awesome and patient. I installed it and not sure how long after I uninstalled it and was charged the $29., and Tony refunded my money. Then I started to think about things and I realized I would never know if this app., was going to help me unless I tried. I connected by email with Tonny maybe 2, 3 or 4 times in a day for a few days. I now have a score of 95% I am so thrilled! Tonny will do the best he can to make sure you are up and running and reaching your speed goal. Take it easy on him. He is worth it!


No. 1 fraud app. nothing deliver after charging the cost. no money back as mentioned on the app. we are going to lodge the complaint to shopify against the app unethical practice of collecting money without doing anything


This app did what it describe. Tony is always there to fix the issues, 5 start for good customer support.


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

The shop works nicely now and the service was quick. Initial results were 99/100 for mobile but not so much for the desktop version. After a couple of emails the desktop version was greatly improved as well and I also got hints of what was slowing the site (different apps crashed often).


Page Speed Gurus are true experts to boost your Website Speed. I really like the personally service and the fast reaction of the developer. I can recoomend Page Speed Guru to all other Shopify Store Owners.


Do not optimized my store like promised. Before the app my store loadead in 5,6 seconds and continues like this. I do not liked!


This app is AWESOME, but more then that, the support and human touch is what is the best thing you get worth far more than the $29 you are charged.

Tommy took our Google page speed score from 84 to 99! Yes that's right... 99... I don't know what to say, I'd give 10 stars if I could.

Thanks a lot Tonny! You guys rock. I'd pay $100 for this app in a heartbeat. :)
