Rocket Page Speed Optimizer

Great app but changed my theme, I'm sorry I lost my temper, I became frantic and upset but this was wrong of me as I know it could have been sorted out in the end. (Please give forgive me) The code changed part of my theme through another app that was installed and shopify managed to rectify the problem. I wish you all the best with the future. All apologies once again. Kind regards, Tom.

We've been using this for a while now and it does exactly what we need which is speed up our product pages and store front.

Simply excellent app. A few clicks and the job is done!
Amazing support from Chris when I had a few questions. Absolutely recommended if you care about your Google rankings.

The app boosted the score, but Shopify has not scored us in over 6 days. The score is blank. When running the Google Speedtest, a lot of the time we get an LPC error code and Google spits us a ? mark for the score. Support has not provided a resolution and takes a time long to reply.

I wish I found out about it sooner! It would have save me countless hours of time trying to find other solutions that simply did not work! This should be part of the built-in apps for every store.

The app seems to work great. It definitely improved my site score by a couple of points. An issue with another app not loading after installing this one was addressed quickly. Thanks for the speedy service and support.

I had an IT guy speed up my site recently, but I thought I would give this app a go to see what happens. Using PageSpeed Insights, my speeds before installing the app were: mobile 47 and desktop 95. After installing the app my speeds are now: mobile 77 and desktop 98. So there you have it, it works. Oh and it was extremely easy to install. Thanks!

Yes, it boosts your speed but it damages your code. Lost of my rich schema results. Uninstalled the app and it is fine again. Dangerous app!

Increased score to incredibly high values, but Google workers don't recommend tricking the Page Speed algorithm as the Search Engine weighs the actual experience of the users more - which is decreased with this plugin. Will update again in 28 days.

This app is brilliant. 2 clicks after installing and my store is already 30 points faster. To anyone who hasn't already, get this app. It's a must have for any Shopify store owner.
