PageSpeed & Image Optimiser

For anyone with a 3th party checkout app ( I have a Cash on Delivery App to reveice orders) dont install this app. I had the issue that customers couldnt checkout because the checkout app was getting blocked. After a night figuring out why customers could check out. I uninstalled the app and removed the code in my theme. For the few days the app was installed ( not used ) i payed 20 dollars.

I am writing a review because it is the only methode to reach you. I cant use customersupport , i have to install the app again

In 24 hours, Marc has helped me improve the performance of my store getting from 70% to 92% on Google Lighthouse because of image issues a lot of shopify stores are facing. He also answered the questions that I had about the app and the customer service was fluid through Slack. For this efficient customer service, I recommend using the app. Thank you Marc.

The app has been very helpful. Marc helped me a lot. I must recommend this app to all of you. I wish Marc will be present when I need him.

Genau das was ich gesucht habe, es waren nur ein paar Klicks nötig und keine Programmierkenntnisse. Mein Pagespeed hat sich teilweise um 50 Punkte nach oben korrigiert!

Finally an app that works! We have a large site, onshorecellars.com, with thousands of products, collections etc. This App is the only one that has worked in 4 years of searching. I have paid thousands for developers to speed up our site with nominal increases in lighthouse scores. We averaged - 35-42. 5 mins altering setting this up we are between 91-93. THANK YOU THANK YOU THANK YOU!!!!

The Flash PageSpeed Optimization app is a game-changer for my Shopify store to optimizing external URLs! The app is user-friendly and easy to navigate.
I was also impressed by the excellent customer support provided by Marc. He was patient, knowledgeable, and went above and beyond to address all my concerns. Thanks to the app and the support, my website is now faster than ever before, providing a better user experience for my customers. I highly recommend this app to anyone looking to improve their website's performance.

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.

From what i can see, I think it's made a positive difference.

An improvement to the App would be to more visibly show the before and after in terms of speed text.

BAIT & SWITCH - There is NO FREE TRIAL!! Do NOT download this app!! They offer a "FREE" trial but in fine print there's up to $40 in usage fees. Zero clue what that was. I immediately removed app. Unsure how this ever got approved.
UPDATE: Yes you didn't charge my account because I caught your little scam of $40 usage fees for a free trial and as clearly stated above - deleted the app. Thanks for the sexist mansplaining tho.
UPDATE 2: This guy stalked me on Instagram and started DMing me. I had to block him. THEN he removed his old reply and came here and starts again. This is BEYOND unprofessional and downright creepy. It's VERY alarming you've become so unhinged over a negative review about FACTS. And yes I did use the app. I downloaded it - saw the usage fee of up to $40 when there was ZERO visible explanation and so I deleted it. The ONLY thing your non stop replies and stalking me on another platform does is prove my point - DO NOT DOWNLOAD this app!

I installed the app for the image optimization as they didn't charge extra for additional image optimizations. But the rest of the functionality is also great and it improved my speed beyond my expectations.
