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!

After going through multiple sprints of speed optimization, I'm happy to say that this app is the best I've found. They even email you a link to verify the improvements on Google. I wish they worked with CSS too.

"This is a good app. Setup is quick (literally 1 step wizard) and it has knobs you can turn if you want more speed. I just wish those were easy to understand for non technical people. Support offered a free audit and tuned some things to help with that.

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

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.

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 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

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.
