Superspeed: Web Vitals

This app deserves more visibility and customers. I've tried other speed shopify apps and they either don't do anything or slow your website down. With this app, you can actually see the improvement in performance yourself by just browsing your website. It is very noticeable. Dan is also very responsive and patient with answering questions and helping you get the most out of the app. I highly highly recommend Superspeed.

I was a skeptic, I had tried other ways of speeding up our site and only gave it a go after speaking/emailing back and forth with Dan at DesinSection9. I have waited a few days to leave my review because although I could see within a day that it was faster I wanted to make sure it lasted. My speed score took about a week to increase from 35 to 47, there was a massive improvement in LCP and smaller improvements across the other core web vital scores.

I am beyond satisfied with this app. For literal years I've been trying to improve the speed of my shopify theme. This has made the biggest difference. Wonderful experience working with Dan, too.

After months of trying different apps on the Shopify App store only to find they made no difference to the speed of our website. We decided to try Superspeed! WoW is an understatement this app is fantastic, within 5 minutes of installing this app, our website was loading so fast, our Google Speed for Mobile is now 80 and our rankings started to increase massively within 3 days. I have been talking with Dan the developer of this app, and he is so kind and has helped us so much, even with other problems we faced with the way things work on Shopify. I can honestly not thank Dan enough, such a great person to chat with and I highly recommend this app to everyone using Shopify, it's 100% a must-have app if you are using Shopify and want to improve your site speed and google speed score. Get this app!

First of all, this app provides the best customer services and Dan is very patient to provide all the necessary information. The customer service team is very strong and even following up my case during the weekend. Secondly, they have strong technical competency, which my site speed has been improved significantly within 2-working days. On the other hand, they keep providing status update and let me know the progress so far. This is an app that you must have, especially if you want to improve the browsing experience for your customer. Excellent experience

This app is one of the few exceptions to the phrase "Too good to be true". As a skeptic, we downloaded it assuming it would marginally help; however, it immediately increased our site speed—a large amount too. Our Google PSI score has been increasing ever since as well as a very noticeable increase in our (semi-heavy) website speed. Check it out in action on our site if you're still on the fence: kalifano.com Support is very responsive and helpful. We highly recommend this to anyone looking to increase their site speed. Hopefully our competition doesn't find out about this gem hahaha…

This is the best app out there because it does exactly what the title says "Superspeed". My store wasn't performing at its best. Now it is! Also, the Customer Service is amazing. They always respond and they're very patient. Thank you!

Really incredibly good contact and honest advice on store speed. I would like to thank you very much for the nice mail contact and the advice...

This app is really amazing, if you do things correctly, you can easily score a 100 on Desktop and 70+ on mobile according to Pagespeed insights. The cool thing about Superspeed is that the app creates automatically a backup optimized version of your current theme and you'll get a chance to check if there are any elements that were broken during the optimization level. You have 4 modes to choose from and you can easily revert the changes if you'd like. Also one last thing, their support is super friendly and knowledgeable. They'll help you fix any issues quickly. Thank you so much

Great app and great service. In addition to the service itself, They helped me fix an unnecessary script in the theme so that the site loaded quickly. This really helped. Highly recommend this app
