PageSpeed & Image Optimiser

It simply make all your images to fake board at the first loading, then make lazy loading to img, BUT in may cases java have failing and images not show up. page speed goes up immediately but it totally ruin the view overall. second thig: it makes 1K back links from one IP.
And support is not answering at all.

I have attempted to contact support repeatedly via both chat and email for several days, with no response. This level of disregard for customers is unacceptable, especially for an app that handles crucial aspects of an online store.

While the app may have potential, the complete lack of support makes it unreliable for professional use. I would advise developers to drastically improve their customer service if they want to be taken seriously in the Shopify market.

Unless you are willing to troubleshoot every issue yourself, I suggest looking for alternatives with more responsive customer support.

"I'm extremely frustrated with Flash Speed Optimizer. As a paid subscriber, I expected my store to be fully optimized, but there's still a 30% unoptimized score on mobile. This is a serious issue since most of my visitors come from mobile, and it's directly impacting my business negatively. Despite multiple emails and chat messages, I've received zero response. This level of neglect is unacceptable. I demand immediate action to optimize my store and compensation for the damage done to my business due to their inaction. Do not trust this app if you value your business!"

I never write a review, usually only if I´m disappointed.
This time it is different.
I´m super happy. The app works perfectly for me. from page speed 37 to 95 (I have screenshots to prove it).
For me it´s a investment and 20 bucks is not cheap, but I rather pay more for something that really works.
The only part I dont use is the picture compressor.

Last Thing I really appreciate: no begging for reviews, no upsells. Just the app.

Perfect.

I installed this app to help me increase my website's speed, because I was unable to edit my code and remove the scripts myself. After this app helped me increase my speed 30-40 points, all of the sudden it stopped doing that. When I contacted the developer, they were not prompt in responding and only said I had to keep checking my speed. Compared to all apps I use, the customer support was by far the worst considering how expensive the app is!

Very expensive and misleading, money pit. It does what they say, but at an unreasonable and unexpected price, way above $19.90 they advertise. Also, they raised their base prices without warning, when I installed, the base price was $9.90

App seemed to be doing a great job, then about 2-4 weeks ago the page speed dropped. I've tried three times to contact support, but no one has gotten back to me.

Unable to reach anyone. App not working. The comparison page speed does not load at all. Tried emailing 3 times no response. Also if you have something like Pagefly, it will cause issues.

We are using a customized Empire theme. It is not obvious that one can improve speed easily n our case. However, I was amazed at how we have gained the speed. The first step was from 40-50 to 85 in Lighthouse metrics. Finally, with the help of Marc, we managed to get that last metric (LCP) to green and the overall Lighthouse score to 100/100.

This app swiftly resolved our JavaScript issue, resulting in a remarkable improvement in our website's speed and overall performance. Highly recommended!
