Swift SEO Page Speed Optimizer

EVERYTHING PERFECT,
EXCELLENT CUSTOMER SERVICE

Super bad customer support, we purchased their OneExperts speed optimisation and they are not even responding. $150 completely wasted. Stay away from these scammers

watch out, when they crop there image. There is no real return back. When they returned it back. Several images are damaged and not usable anymore and they leave you without real support. For large shops definitely not a good one.

Very helpful team that go the extra mile to solve any problem! Recommend!

I strongly advise other business owners to be extremely cautious when using Swift.

I paid for one of their higher subscription tiers for almost four years. During that time, Swift’s “optimisation” process cloned my Shopify theme templates rather than applying changes to the original theme. This was never disclosed.

I then added changes to my optimised theme, over years building my site up to it's now end stage. The result is that, because i used swift and because swift cloned my theme, the official theme updates can no longer be applied. My site is now locked into an outdated structure, and years of refinements are trapped unless I pay a developer to undo Swift’s work.

Swift has acknowledged the structure exists and is technically able to migrate the code to an updated theme, but they refuse to do so unless I pay for expert help again. I had paid for expert help years ago to make my site faster and i never saw the promised results, so expecting me to pay them again for something that is their fault is frankly an insult. Despite this, they continued charging me £30/month for years and repeatedly pushed me to pay for additional optimisation and “expert” services.

Key issues to be aware of:

Lack of transparency: You are not clearly told that optimisation may clone your theme and block future updates

Ongoing upselling: Repeated requests to pay for new optimisation and expert tickets despite already being on a high-tier subscription

Responsibility avoidance: When long-term issues emerge, they are framed as “out of scope” or your problem to fix

In my case, the service has left my site worse off than if I had never used Swift at all, and I am now paying to remediate the damage.

If you value long-term maintainability, theme updates, and clear accountability, I would think very carefully before using this service. Take it from me as a customer of years, they do not appriciate or respect your custom and i will be taking them to trading standards as misrepresentating their services.

Highest recommendation for this app and the great team behind it! I worked with Rosie and it only took a couple emails and less than a week to get everything taken care of. The communication was excellent despite the different time zones, and the team addressed all my concerns. Extremely happy, thank you again!

Trust me, it's the best SEO app on Shopify! We've tried other similar apps, but Swift's team has been the most responsive. Julie always provided quick feedback and even helped us fix a bug caused by another app's developers.

great to work with done a good job of fixing the issues on our site

Hired an expert only for $150 and they solved every problem on my homepage! Thank you so much for this!
