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.

We installed the app and were in contact with a member of their team. He noticed that we were using other plug-ins and proceeded with manual customization. Apparently, no testing was conducted after making these changes. As a result, our entire front page became non-functional, and product images failed to load. This issue cost us a full day of revenue. Completely unacceptable.

Hi, The issues you mentioned are caused by the landing page app, Visually.io.

It's not working even on Shopify Dawn theme...
He didn't even tried to make it work. Each consequent "fix" will decrease my store speed to around 50.
Even if the app doesn't work, they still charged me.
The first answer was a recommendation to just uninstall the app, which say a lot about their ethics.

This app works properly with Dawn theme. The issues you had were related to 3rd party code (wishlist and dynamic buttons). Our team was very upfront about the incompatibility with these but you kept emailing support several times a day about it. We suggested uninstalling the app as we didn't want you keep getting billed for something that clearly won't work on your store.

Great app, it actually changed the scores on pagespeed. Love the instant page load feature.

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.

When you get the dreaded email from google about your site being slow, this is the tool you need. It identified which apps were causing the issues and fixed them for me. Didn't have to change my theme and anything. Just installed the app and it fixed everything.

I got a 15 point bump in page speed just by installing this app. I think it can help me improve my SEO and get a faster page in the long run.
