Swift SEO Page Speed Optimizer

The day I installed this app was the day my website went insane. I had multiple issues right out of the gate with this one. I ran the free speed optimizer and also used their image tool to optimize 100 images. My thinking was I would test the free version, and if it worked I would pay for monthly optimizations. Test failed. The first, and biggest problem, was that the app made a duplicate version of my website. I did not realize right away, but the "optimized" theme was downgraded from Dawn 7.0 to a modified Dawn 4.0 that was unable to update. And not just the theme it duplicated....ALL my backups were suddenly Dawn 4.0. My website is less than a year old, Dawn 4.0 was never previously installed on my site, ever. I also had multiple product images that simply vanished and needed to be re-uploaded. On mobile, my product image swipe quit working. Even though it would say 1/4 images....It would only show one on mobile. I also had two "sale" icons on the products that were on sale, and one was half way off the screen so it was definitely causing glitches. Random icons on my website also disappeared and my website was overall glitchy. The optimizer tool got my page speed from a 28 to a 41 right away. However, the next day I was down to a 21 page speed and my website was simply not working. I decided to try to update my website to Dawn 9.0 since 4.0 was such an old version I figured that could be part of the problem...But no, the theme was modified and could not be updated. I had to download a fresh version of my theme. None of my page templates would transfer....I would have to completely re-design my website. So I got in touch with Shopify support hoping for an easier solution, who told me whatever the optimizer did to my theme to remove the "unused" javascrips and css, did something to my theme files. They suggested I contact the app developer support and ask for whatever they did to my website to be rolled back or removed. The Swift app developers got back to me quickly and looked into my issue, which I was happy about. However, they came back and told me it was "impossible" that my themes were downgraded to 4.0, and that it was "unreasonable" that I did not notice immediately (Do you check what version of theme you're using every day?) They offered zero solution, and told me to go back to Shopify with their email. So I did. Shopify support agreed that the email from the Swift app support was incredibly unhelpful and basically dodging responsibility. I spent a whopping four hours with Shopify support, and spoke to multiple people as they sent my case up the ranks to figure out why my site wouldn't update, why there were so many glitches, and why none of my page templates would transfer to my fresh Dawn 9.0 theme download from the modified 4.0 themes. After all that time, it was finally suggested that I just rebuild my page themes and redesign my website. We had to delete all my old backups that were corrupted by the Swift Page Speed Optimizer tool and start over. Devastating. After removing all of the theme backups that were corrupted and starting on a fresh theme download....My google page speed went from a 21 to a 64. Removing whatever the Swift app did, fixed everything. My website now runs flawlessly with a vastly improved speed score. In hindsight, I should have just upgraded to 9.0 before trying this app. I asked the Shopify support rep how a Shopify app from the Shopify App Store could so severely damage my website files...and they told me that Shopify has no control over what apps are on the app store and to use caution. They told me the best thing I can do is to leave a detailed review of what happened so other users may not have this problem. So here I am . I give one star for the support team responding to me, thanks for the response, as unhelpful as it was. Otherwise, I would avoid this app, or any app, that automatically alters theme files. Zero stars. Show more

My store speed increased dramatically after their optimization with OneExperts service. After optimization, we were able to pass Google Core Web Vital on collection page for the first time. The Google Page Speed performance test score for the product page went from 22 to 66, which is a huge improvement. I definitely recommend them. Show more

I tried Swift Oneexperts to speed up my website and and I have to say the results were amazing. My homepage score went from 18 to 84 while my collection and product pages also saw significant improvements. Their customer service was top-notch too. If you want to upgrade your page speed, I highly recommend Swift Onexperts service, they really know their stuff. Show more

I recently used the expert service to optimize my store, and I was very impressed with the results. The team was very professional and responsive, and they were able to increase my website speed by about 50 points. I also appreciated the detailed report they provided, which helped me understand the changes they made and how they would impact my website. Overall, I would highly recommend their service to anyone looking to improve their store speed and performance. Show more

It technically increased the speed but it creates a bunch of issues with our site and conflicted with some apps. Weird bugs showed up and they calmed it on the theme even though the theme was working perfectly before. Hours of explaining and debugging but it was never perfect. They operate from Vietnam as well. Their code seemed wonky and causing more trouble than goods. Uninstalling the app. I wasted tens of hours on this. Giant fail. Show more
