Swift SEO ページスピードオプティマイザー

Didn't work with my store but once I reached out about canceling I was helped through customer service. May work with your store though.

although there was an improvement over my original score in the end, the installation of the app was the only event on a day when my shopify speed score lost 13 points. i do believe that this is intentional on the part of the designers in order to incentivize you to pay for the expert optimization. that being said, my site is faster now than it was before the 13 point drop so they did as they ...

After the help of the Swift experts, the speed improved significantly. They also give accommodations for further improvement in speed.

The great thing about this app is that you can put your logo and custom colors for absolutely free which is awesome. But if you want things like lazy loading etc. for your store you do have to pay a monthly fee for it. Other than enjoy the basic plan because it's a lot for a little.

The app has a very nice/understandable UI and extremely good support (also from the product manager personally). They make an effort to tackle individual problems. The functions have not worked 100% for me, but I am convinced that the team will find good solutions.

Supportive

We installed this app to improve our stores speed. Tommy from the customer support helped us checking what is the cause of slow speed score and gave us some advice and recommendations to improve, we will be updating our review after we get some results for sure. Thank you so much.
