Rocket Page Speed Optimizer

I've been using this app for years, and it has improved my CWV scores. The customer service has been responsive and helpful as well.

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.

I have tried SEVERAL so called Page Speed tools. Some of them were very expensive! Each of the tools I've tried provided varying levels of effectiveness (from very good, to terrible). Some even broke my theme entirely. On a whim I tried this one. WOW! Our pagespeed scores have come up nicely. Not mind-blowing, but an impressive bump. We've moved from unacceptable speed levels to above average speed levels. And our Web Core Vitals are spot on now. How can something this inexpensive work so well? I haven't got a clue. But I can say this with assurance -- this app is a keeper!

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 install it a few weeks ago and I did have my doubts but I have to say the site is quicker it took a few days to show up on the Shopify speed score but that has jumped and on Google, the site speed score has also shown a big leap in the positive direction so well worth the small monthly fee as far as i am concerned

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

I have tried everything. Downloading so many apps that say they improve my speed only to have my Google page pes score and Shopify score LOW! This app is a dream come true! It literally boosted my overall score on mobile AND desktop by 20 points via Google page speed AND Shopify score. Seriously amazing. Thanks guys for all you do. I’m no longer pulling out my hair!

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.

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. Thank you for the review :)

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 was gonna give up on this app. Installed and had small increased in speed. Wrote to support and Sam did some tweets, thereafter loading speed doubled for mobile! Very happy now....

Amazing app that has increased our mobile site speed by about 50 points I reached out to support and they helped to increase this more now showing mobile speed of 80. Our desktop speed now at 99. I highly recommend this app as it will continue to help in the future too. Thank you to Sam for all your kind help and support.

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.

Did exactly what it said it was going to do! Improved my mobile pagespeed score by 24 points but reducing the total blocking time and deffering 3rd party app scripts. Really pleased.

Increased the google page speed score from 17 to 47 for mobile & 70 to 83 for desktop instantly. Would definitely recommend this app.

This simple app makes satisfying Googles new Core Web Vitals childsplay for mere mortals like me. Great little app, with a team behind it who really care and support their technology.

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.

Great Service so far and great app! Has already increased page speed! Thank you! I cant wait to see what this does for my rankings

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 added this app to help increase page speed and it worked immediately. The owner was also extremely helpful when I had questions and needed help.

Surprisingly, this app made improvement even after we have manually optimized the store already. Excellent support responded in 30min after we encountered a problem with qikify.com smart menu.
