Great support and helpful features! I used Plug In Useful for a while and found its features very practical — especially for identifying SEO and site speed issues in a clear, actionable way. What really stood out was the support team: when I needed help they responded quickly and handled everything professionally. Highly recommended for anyone looking to improve their store’s performance with solid customer service behind it!

Really enjoy this app, works great to optimise images, with very little interaction. Also, provides ability to roll back any changes you may not be happy with, and also allows side by side comparison of unchanged / changed.

AMAZING customer service! My store crashed and I thought it was due to the app, however, it turns out it wasn't. Regardless they went into my store's code and went file by file to get to the root cause, fixed it (way beyond their scope) and got me back up in running. Highly recommend the app and the team!

We downloaded this app to help decrease our page load times. After running the Google mobile speed test our website was ranking slow which directly impacts search rankings. One of the tips the Google report recommended was optimizing our code and CSS files, along with optimizing images. This app does both so it seemed like a perfect solution! Right off the bat our page load times decreased and we were ranking higher than our competitors sites. This is a HUGE advantage for us and we owe it all to this app! Further, I contacted the support team later in the evening, not expecting a response until morning. Not only did they get back to me within minutes, they answered all of my questions right away! I could not be more impressed! I would give this team 10 stars if I could. Thanks for the assistance and for the great app, I would highly recommend trying it out!

I used the app to speed the site up as we were having loading issues. It worked a treat to optimise the images, and was very easy to use. Plus, i'd had a recurring issue with the site that was unrelated to why i'd downloaded the app, yet when i mentioned it to their support people they were so helpful. They went out of their way to give me a very in depth explanation as to what needed to be done to fix the issue which i went to my developer with. Very Very Happy
