Rocket Page Speed Optimizer

I've been using Page Speed Optimizer since August 2024, so for about 6 months. I use Dawn theme and update regularly. This app works as advertised - pushing my Page Speed Insight performance score up from the 40s and 50s to the 90s across my Shopify site (blog, pages, products, homepage...). Page speed is super important for SEO and this app has positively impacted this aspect of my SEO work. The best part of the app is the customer support. Over the months I've had issues with other apps bringing my performance score down. I email Kirkland and within hours they've tweaked my implementation and solved the issues. Fast, friendly support. App works better than expected. 5 stars - definitely recommend.

Amazing App, the only one that significantly reduced the LCP of my Website. The customer support is very fast and reliable. Definitely recommend!

Highly recommended, always an updated site-speed and a good Core Web Vital performance. Even if you make big changes on your site it will always take care of he optimizations again. Sometimes a couple of days later, but always it brings you back to an optimized and good score. Nice app, easy to use and also friendly and good support.

What is this sorcery? I've been through thousands of pounds trying to find someone to improve our site speed. We've gone from a site speed of 25 to 70. Insane! Well done team, you are incredible.

I don't know how, but this fkn thing works! Went from 23 to 60 in 3 days. Super easy to install, 0 hustle. I wish I could find this app earlier. Good job, guys!

I was sceptical about this app. I thought it is bs. My website speed almost doubled (according to Shopify speed score) within few days. How about that?

Just wanted to give you an update on the work you did. Last week, we were F – worse than our worst major competitor. And now we are A. We had an LCP of over 7 seconds and now we are down to half a second. The results you have had on our site are nothing short of incredible. I don’t know how you do it and I suspect you won't tell

Just want to see a big thank you to support and Sam. I am now 72 on speed score ( was 18 ) and 99% good URL'S ( was 23% ) on Google search console. Your app is amazing, keep doing what your doing. A Very Happy Customer

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.

Honestly don’t understand the metrics, but my mobile speed insights rose from 37-68 and the desktop rose from 74-90 for my main page. And 26-60 + 79-98 for a secondary page I’m focusing on.

Since inception, we had a speed score ranging between 17 - 20, day after day, month after month, even after minimizing images, etc. It never went above 20. Within less than 24 hours of installing Core Web Vitals Booster the score went to 27, and the following day it went to 35. Very Happy with this App!

The amount this has increased my core web vitals performance is good impressive it almost seems too good to be true. I am shocked and overwhelmed with how this has shot up my performance. I just hope it will not cause conflict with any of my apps ect.

I just LOVE this app! I have struggled so much with our site's Google page Speed rankings and you guys solved all this in one click! Now I can finally build the site I want with the content I want without having to worry about a "red flag" from Google everytime I add a functionality! THANK YOU! Definately worth every penny! https://shavent.store/en/

I was extremely skeptical about this app and just added it to try out. But it has improved PageSpeed results but also in about 2 weeks, my page passed core web vitals assessment according to field data, I was not expecting this since most big websites even cannot pass this and encourage people to use mobile apps. I think our SEO will improve accordingly since Google weighs too much importance on user experience.

Does exactly what it says it will! Greatly increased my store's speed score (for first time users which is the most important)! Well worth it! If you don't have this app, you're missing out!

This app really helped speed up my website ALOT. I am seeing the best data result since installing it. I recommend it.

I’m so impressed! It took a few days and a little back and forth with customer support, but make a huge difference in my speed score. At first lighthouse showed a decrease in SEO score but that was resolved within a few days too. Well worth the reasonable monthly fee, I’m so relieved!

Fantastic app. For months we have been researching how to get out of the red in the Google Speed Test and pass the WEB VITAL TEST. This app took our worries away! The app does a lot of things automatically, but the final, true touch comes from manual settings that the support completed within 24 hours from a mobile score of 39 to 93 and Deskop 69 to 99. Simply unbelievable what such an app can do! THANKS VERY MUCH! WE RECOMMEND!

Added this app to specifically increase my shop's speed and to address the new requirements from Google's latest major update. The initial boost in speed was great and made even better by the customer service team who was quick to respond and help. Highly recommend you trying this app out.

I've never seen a support THAT reactive! Thank you so much for your quick help! A part from that, it really helped boost my store without any doubt.
