Superspeed: Web Vitals

Superspeed and Dan do an excellent job on the app. Their attention and support in solving problems is very precise and they continually strive to release updates that improve the performance of the online store.

Amazing level of service! Not so much an app as "an app plus a guy who knows everything and doesn't seem to sleep". Phenomenal service.

Highly recommended!! Dan is a real professional who will help you quickly (and also with things that are not related to the store's speed but other problems you have).
After only two days, my shop speed score on Shopify almost doubled! And Dan is always trying to make it even better.
Believe it or not, he never offered me to write a review (like all apps do after a second of use in exchange for benefits...) I was the one who asked for a link to write a review.
In my life, I have never encountered such an honest and decent person as Dan. After a certain malfunction (which was not his fault - due to a change that Google made on their side...), he returned all my subscription money for many months - again! Without even asking! And then do whatever you can to fix the problem!

The number of times Dan has helped me, even in things unrelated to his area of expertise (code matters, store design, and more... a lot more...), is simply enormous!!! And all this without even asking for payment. He is a true professional and a very decent person.
Undoubtedly, this is the best application (and customer service) I have ever come across! Thank you!!

Again - the best!

Highly recommend this app. Super easy to install and setup, the plans are simple, and there's an instant site speed increase immediately upon implementation. We all know themes and CMS platforms all have their pros and cons, and this app keeps things simple, and is very efficient/effective right after install. The fact that I can have confidence the app is also monitoring my prioritized pages, helps me rest assured everything is firing properly. I love being able to load the app, and immediately see page insights/speed in the dashboard. Above all, I struggle with customer service with most apps, and we value people with my business, and so does this team. Five Stars, keep it up team, great work.

If you have a resource heavy website this SuperSpeed app is an absolute must in combination with their ShopySpeed Optimization Service. *Otherwise the SuperSpeed app alone 'may' be all you need. Using both the app and service our website's Google Insights performance score increased 306% and our conversion rate increased high double-digits! The developer (Dan) is an expert in Shopify Speed Optimization and is one of the best developers I have worked with. Just install the app, contact Dan and your store will be flying.

Passing google page speed insights now and Superspeed is the real deal. If you care about your PSI score, get this app installed asap.

Five stars really isn't enough for this app and service, we have been using Superspeed for over 2 years now, and our business really wouldn't be able to operate without it! We initially installed the app hoping for some improvement in website speed, however, our expectations were far exceeded, and we were amazed to receive a full appraisal of the areas were our website could be improved and how it could be done. Dan is a true expert, and very clearly advises on what can be done, how and why, and on top of that, the app itself provides everything you need to regularly monitor your site for improvements. Our website speed and optimisation improved straight away and has continued to serve us well, with our rankings rising also, which means more sales! Recently, we have made some significant updates which required further assistance and Dan has once again been fantastic! We have not been able to find an app or service like this before or since! Thank you!!

I'm super impressed with how this app had helped our site speed. Overall, their customer service is phenomenal and their other site services they provide are super. I think this app is a must need for anyone looking to do serious business on their site.

Fantastic app - does exactly what it promises. The team at Superspeed has been extremely hand on and helpful with the setup of our app. Very happy with it!

That worked!!! I've tried a bunch of different apps/hacks/tricks to make our site speed load faster. I installed Superspeed and BAM we went from a pretty-good GT Metrix score of B up to an A. Our overall score went up from 78% to 90%. Nice Bump in speed! This one's a keeper. UPDATE: Well I have to say it just keeps getting better. Their team finished installing the "Worker" version of the app to our site (no extra charge). Speeds increased even further. I never dreamed that our site could reach PageSpeed Insight scores of 98% on desktop and over 70% on mobile. This is the absolute BEST $29 I've spent on our business, by a long shot. If you care about the speed of your site (and you should) — get this app. It'll move the needle in a remarkable way!
