I recently started using the Thunder app, and the results have been phenomenal! My Shopify store's loading time has significantly improved, and my customers have noticed the difference. The interface is user-friendly, making it easy for someone without a technical background to navigate and implement optimizations.

The support team is outstanding—they responded to my queries promptly and even provided personalized suggestions to further enhance my store's performance.

Before installing Thunder Page Speed Optimization, my site was experiencing slow load times, which affected the customer experience and, ultimately, conversions. But with Thunder, everything changed. Now, it’s hands down the best solution to speed up my Shopify store!

I'm really impressed with this app. It's not just about speed improvements - it helped me identify other issues I didn't even know I had.

My First Contentful Paint dropped from 7s to 1.6s, which is huge!

Big shoutout to Georgi - I was shocked when he replied to my support request within a minute. That kind of responsiveness is rare these days.

The interface is straightforward, so you don't need to be a tech wizard to use it. If you're looking to seriously boost your site's performance, give this a shot. It's been a lifesaver for me

Great customer service! Highly recommend.

We had a issue where our dashboard wasn't updating properly. George was super helpful and went above and beyond to get us up and running asap.

Most apps do not improve Google page speed!

This is the best app I have ever tried to speed up the site, showing noticeable improvements even on the page speed!

It's very simple:

After installing it, just go to "Optimize," leave the level on "Standard," and click on "Generate optimized preview." That's it :)

The plus of this app is competent and always available support that will help you with any doubts or problems!

Thank you, Georgi, for the help!
