Thunder Page Speed Optimizer

Overall, it’s a useful option for stores looking to add upsells without much complexity.

They have perfect support. My website had issue but they fixed it quickly. I love this app and this support.

Thunder Page Speed is an excellent app for Shopify store owners! The app is easy to use, and I really like its user-friendly interface. It’s a great tool for optimizing store performance and creating a smoother shopping experience for customers. Highly recommended to Shopify merchants looking to improve their store speed!

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.

Great app for improving Shopify store speed. Easy to use, works smoothly, and the support team is very helpful. Highly recommended!

Really impressed with Thunder Page Speed Optimizer. The setup was quick and easy, and I noticed an improvement in my store’s loading speed without needing to make complicated technical changes. The app is simple to use and the support team is also very helpful. Definitely a useful app for Shopify store owners looking to improve their store performance.

This app is must have! I launched my shop soon and was waiting to see the speed score. When I saw score 23 I was shocked. I'm not so tech person and didn't know where to start from.... Then I saw Thunder Page Speed Optimizer. I just deside to try and to see if anything will change. This app exceed my expectations!!!!! My score jumped from 35-60 on PageSpeed Insights! The score gets almost double and this is without me doing anything! I'm so greateful for this and I really think the score will get even higer, because shopify needs one week to show the new score. Highly Recommend!!!

Very helpfull and easy to install and use, page speed speed up with thunder. I ask for something and George respond fast and honest. Keep up this

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.

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 reached out to George once i installed the app to see what he could do for our store - it took a while for a response due to technical issues he was having with shopify which are now resolved. He has since got back to me and offered his skills to help improve our stores score overall and asap

I can’t open the operation page all the time, and there is no reply to the email contact. There is no reply after contacting for three times in a row. Extremely bad service

Assistenza impeccabile devo dire app molto funzionale e costa poco rispetto ad altre app molto costose e forniscono un assistenza pessima. Spero tanto che questa azienda cresca se lo merita darei 10 stelle ma non posso

Theme editor stopped working after was removed. Site editor is messed badly.

bad support and speed of site still not good

Okay so my service earlier with them wasnt that good, but there customer staff actually contacted me and he even go 1 step ahead for optimizing the website. current i am testing the optimization, i will for sure update about it.... but for the customer Support, and the help they have done..... It was great

Really simple to use and works smoothly. Great app with useful features. Highly recommended!

We wanted to try the app, but the experience has not been ideal. First, optimizing the theme, which should take 10-15 minutes as per the instructions, took over two hours and never finished. After that, the app simply stopped loading, giving a "refuse to connect" error. We emailed support, and they reached out offering to help. Unfortunately, we had already installed and set up another app.
