Thunder Page Speed Optimizer

I highly recommend using the app and working with George. He helped me with optimizing my store and resolved critical issue with CLS (visual stability problems). I think an app like that is the future of online store optimizations. I must also add that I am a newbie to subject like this, I always feel dizzy while talking with developers - but not with George. He has high communication skills and I understood everything he said and every process he showed and explained. I appreciate the experience and results.

I recently started using this app for my store, and I've been absolutely blown away by the results! Within 15 minutes, my pagespeed score DOUBLED (40 to 80!!!) and my speed score in Shopify has been increasing every day. Special shoutout to George. His expertise, quick responses, and willingness to help went above and beyond my expectations. He even implemented some custom optimizations for my store. If you're scrolling through the app store, deliberating over which speed optimization app to choose – stop right here. With blazing fast improvements and stellar support, you've got all you need. Full five stars from me!

We brought on an SEO company that really pushed us to get our speed of our website up, but things like "unused java" even stumped our web developer. Added this app cautiously after looking up various apps and it has been a hit! Initially store went from 30 up to 55, after every theme update I run the app and there are always improvements.

Quick support! Had an issue with app not loading and it was reaolved within 30 minutes or so. Great reaponse!

The app is great and the developer is very willing to help you fix issues with your store speed.

There were some minor issues in the beginning, but George handled them promptly and efficiently. Considering this is a free app, the support is better than most premium apps. George went above and beyond to handle everything and together we managed to improve my website's PageSpeed to an all time high score, now passing all Core Web Vitals metrics. I recommend this app to anyone in need of improving their PageSpeed score in a safe and efficient way. Be sure that you're in good hands with George and Thunder app.
