Superspeed: Web Vitals

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.

Finally an app that can actually increase store speed! Have been using it for a month and already seeing improvements. Customer support is incredible. More eCommerce stores should be using this app.

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.

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!

Superspeed has had a huge impact on our site's speed score. Most of our key landing and product pages have increased from mid-50s to mid 80s and 90s. Faster page loads makes for happier customers. We're hoping that over time this will increase our SEO, too!

Woh! I'm heavily impressed.
Dan and his team significantly increase the performance of our shop.
Before using the app we failed the Core Web Vitals test.
The app improved many metrics.
And the support by Superspeed was absolutely phenomenal. They answered and acted very quickly.
And Superspeed does everything to get the best performance possible for their customers. I can highly recommend Superspeed.

Hallo wir können die App nur empfehlen. Hilft uns sehr die Geschwindigkeit zu bekommen. Der Support ganz besonders Dan. Also er ist einfach Spitze und sehr bemüht alles zu machen. Wirklich sehr gut. Danke

Yeah, this app does what it says. It couldn't have been easier (literally one click) and the app is incredibly effective. The only thing better than the app is the customer service. They are a delight to work with.

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!

Optimisation apps are always the most delicate to choose. Some bring no benefit, others only cause problems. After several attempts, we installed this one and it was the only one that gave us benefits right away, the Google speed insight score went up and the vital signals test was passedafter some days.
Not only does the app works great but the support is terrific and incredibly accurate. Dan provided me with information that will allow us to optimise the site even more, ad with a lot of free of charge knowledge. A++
