Thunder Page Speed Optimizer , 31 reviews

Probably one of the best app if you're looking to speed up your shopify theme, it helped us increase our score by 21 points!

Holy Macaroni, this worked like a charm. It was quick and took me from ~50 to 90 on Mobile, and to 100 on PC! I'm amazed.

I used this app on a previous store Spritual Splendors. I am now using it on Sipsationalcoffee.com my page score originally here is 40 lol. I know that it will increase as it did my last store. Now I am waiting for it to optimize so I can test everything then hopefully roll out today. The price you pay for 91 SEO score on pageview is sometimes slower site.

is like payed, but is fre!!! amazon app saved my store was the only app that made it work for pagespeed

What an amazing experience with this app, highly recommended. There is no risk trying, you're guided throughout the process, and you test before deploying live, so you know it works properly. I'm just amazed how the whole thing went. Feels faster and I can just say thank you!

wow, how is this free. Increased my sites speed with multiple seconds. I highly recommend this app to anyone its amazing

Increased our speed. We got some help from the team, Georgi, and felt like he took great care of us and made things work great!

I am incredibly grateful for the amazing app you have created! The founder, George, provided me with exceptional support that exceeded my expectations.

Critical css, image resize not working on my website. Not sure if prefetching works. Within the code of loading bar and therefor sort of hidden, a link to https://www.w3.org/ creates "the largest contentful element" with error, read by website speed anaylizers also as an error, somehow registers for a higher speed. The only true benefit using this app was compressing the css file and nothing more.
