I am beyond happy with the results from my Swift speed optimization. My store now loads in under 500 milliseconds! At its lowest point, it stagnated at a sluggish 33. Swift brought it up to 90!!!! I can't wait to see what impact this will have on traffic and conversions. Thank you so much, Swift!

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.

5 stars. I was hesitant to pay the $150 to optimize the webspeed, but they did a very professional job and got our website incredible load time results. We ended up adding more to the site a few months later and our site speed dropped, the staff was SO helpful in accommodating us and took care of the issue for us within one hour. The customer support is top notch and I got a better return on investment here than any UPWORK freelancer could have done. Saved me time and money. Thank you again.

AVOID THIS APP AT ALL COSTS IT HAS CORRUPTED THE THEME ON OUR STORE!!!!
ABSOLUTELY CATASTROPHIC LOSS OF DATA DUE TO INSTALLATION OF THIS SWIFT PAGE SPEED OPTIMISER APP. From the moment our developer chose to install this app it corrupted our Theme and we have LOST SIX MONTHS WORTH OF SITE DEVELOPMENT. This is THE MOST STRESSFUL SITUATION. PLUS THEIR SUPPORT IS ABSOLUTELY USELESS AND THREE DAYS AFTER THE CATASTROPHIC CORRUPTION OF OUR SHOP THEY STILL HAVE NOT MANAGED TO RESOLVE THE ISSUES. WE ARE ANGRY BEYOND WORDS.

So I recently tried out Swift's expert service to improve my website's speed score, and I gotta say, I was pleasantly surprised. At first, I was skeptical of the Google speed score, and I didn't want anyone messing around with my website's code (like mentioned in some bad reviews). But Julie, my contact at Swift, was super helpful and patient, and she answered all my questions without being too salesy. That reassured me.

That being said, I was a bit disappointed that they didn't mention the requirement of an up-to-date theme before taking my money. In my case, I should have updated my theme a long (long) time ago, and it was an easy fix since I developed the website myself. But for people who rely on developers to manage their website, updating the theme can be an additional and significant cost. So I think it would have been better if Swyft had made this clear from the outset, before taking the money.

However, once I updated my theme, the team got to work quickly and provided a report within 24 hours. They were very careful not to make any changes without my approval, which I appreciated, and they even provided a backup and preview before publishing. The results were fantastic - my website's speed score jumped from 30 to 70 (my theme was even at 15 before the theme update...so at the end an updated website is playing a big part in your score too). They also provide you with a full report after optimisation that really shows that they did a complete job, and it brings real transparency to the relation.

Now, I'm on the monthly expert care plan ($49), which includes a monthly ongoing optimisation of the Google Score to keep it always optimal, and an image optimisation app. The last feature can replace another app I already have so it makes the plan a bit more profitable (I am just waiting for them to activate the automatic image optimisation feature). Plus, the preload website feature that uses Google Analytics to pre-load pages based on customer behavior is another cool addition that makes the plan even more valuable. Take that in consideration, if like me, you find that $49 is a bit pricy. At the end, you can make it a good value.

Overall, I'm really happy with Swift's expert service. The team was respectful of my website's code and provided a valuable service that helped me improve my website's performance. Julie was a big part of why the experience was so positive, and I appreciate how the team is communicating very well internally (between sales and dev). If you're looking for a way to boost your website's speed score, give Swift a try - just make sure your theme is up-to-date first!

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.
