Thunder Page Speed really helped my shopify stores to get faster and the impact it had on our SEO efforts was visible only after few months. Now I am putting Thunder on every shopify store we open because it is really worth it knowing there is someone constantly making sure your website is as fast as possible.

The automatic speed optimizations are a life saver! We make a lot of updates on our website and it makes us so much more confident when we know everything is optimized. Our speed score improved significantly few weeks after installing Thunder page speed! Recommended!
