  Dan is the best! I use SuperSpeed for all of my clients. I used to have my dev teams spend weeks on optimization. Now I just install SuperSpeed and ping Dan anytime we need to re-optimize. All of my client sites now pass Core Web Vitals no problem. I don't know how he does it, great price for always having a fast website! Thanks Dan!!!

  Amazing Experience with DAN! You would think this app only monitors the site, what is not explained properly that they also optimize most of the shop for you and find the bottle necks

  Instant Game-Changer! I just started using the Superspeed app, and I'm blown away by the immediate positive impact it has had on my Shopify store's performance. From the moment we activated this app, I noticed a significant boost in page load times and overall site speed. As an online merchant, I can't stress enough how crucial it is to have a lightning-fast website, especially in today's competitive eCommerce environment, where customers expect near-instantaneous loading times. Slow websites are a surefire way to drive potential buyers away and negatively impact conversion rates. The Superspeed app has optimized my site's assets, and implemented various other performance-enhancing techniques, all without requiring any technical expertise on my part. The setup process was a breeze, and the app seamlessly integrated with my existing Shopify store. My website became noticeably faster. I highly recommend the Superspeed app to any Shopify store owner who wants to take their site's performance to the next level without the hassle of complex coding or manual optimizations. The instant results speak for themselves, and I couldn't be happier with my decision to incorporate this app into our eCommerce strategy. Thank you, Dan, for the quick turnaround and your Ninja level skills! Your professionalism and attention to detail are truly appreciated.

  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.

  10/5 if I could. I'm very grateful and willing to spend on this app, because Dan customizes it for YOUR store and is willing to even tell you, educate you, on what he did itemized. Like who does that for people these days? It's going to help all of our conversions as we scale. I highly recommend this app, and if you need help, just ask. Dan is quick too. Idk how he does it so fast, but it's great and I feel like I'm doing my part by having the right team on the job. THANK YOU!

  Superspeed and Dan are exceptional at what they do, so if there's any doubt in your mind, the app is incredible, and more importantly it's the support Dan provides behind the scenes to help you resolve the issues that makes this app exceptional. We have tried a number of different 'speed apps' which actually made our rankings worse, only to find SEO going down and real-life speed not improve, and other numerous issues come up. Superspeed is the 'real deal'. What's even more impressive aside from Superspeed and Dan's expertise is the support to resolve all sorts of issues that support in other apps wouldn't help us to fix. Our site is far faster than it's ever been, and we wouldn't hesitate to use the app on other sites. We'll certainly be recommending Superspeed to others.

Work on Superspeed: Conversion & Speed?

Any amount puts this listing above the review-data order, on the board and in Marketing and conversion. Every amount and every click is printed in public. Paying also opens a private page for this listing – that is where the badge for your site, the share card and your deal live. Everything you can do here, including what money cannot buy and how to get this listing corrected or taken down.

Not ready to pay for anything? Take the badge – it shows this listing’s live rank on your own site, it is free, and it always was.

Claiming is free and it shows: the listing turns gold in every list – the same highlight a paid card carries – with a Claimed badge, in the exact place its reviews put it. It also earns the only followed link on this site: a claimed listing that has paid nothing links to its own website dofollow – a paid placement never does, because a link that was paid for is an ad. Claiming moves nothing.
