Superspeed: Web Vitals , 66 reviews

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++

My store speed almost doubled since we installed this app. The customer support is also wonderful and very helpful.

Dan was so insightful and truly instrumental in getting our site speed to surpass anything that would have been possible without Superspeed Google's Page Speed app. Now we're running quicker than ever and in a better position to place better on Google. The work was quick and exceeded expectations!

I have tried EVERY SPEED APP on the app store. I have been satisfied with a few other, but they just never did the trick. I decided to just try Superspeed app because... heck why not. I installed the app & immediately saw results. What I loved the most was how Dan really took the time to make sure the APP was working at its maximum potential. Don't believe me? Go to my store & see how quick it is!

The team is very enthusiastic. My store performance score has risen from 17 to 38. Thank you very much

I really love this app.I've searched the website speed app for nearly 1 year on Shopify but no one is better than Superspeed.Dan is the most professional i've ever met.Fast respons and the most important.my speed of online shop is 10x faster than before. TKs again Dan.

This is the real deal. Took my speed score from low 30s to 95. Dan is the Don. Price is a little high compared to the other apps but for that price you essentially employ someone to keep your store running super fast .

The widget is awesome, Especially the co-founder Dan. They are very responsive and helpful. Website speed improved significantly!

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