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.

UPDATE:
They replied and advised me to uninstall the application.

After about 15/20 days they contacted me to tell me that the problem was solved and actually now it works very well.

Thank you

The application is great, but the support service is terrible.

I have a small problem with the app, the dashboard no longer works for me.
I wrote him 3 emails and 2 messages through Shopify, a week later still no one has replied to me.

Most of these page speed apps don't do much, this one seems to be the real deal. The developer was very responsive to communicate and was able to help get things going within 24 hours of setup. highly recommend.

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.

OMG!... A FREAKING APP THAT WORKS as it is supposed to! .. So if you are a small business owner with the technical knowledge of a rock but you know a mess load about SEO, Ranking and Spending a Crap ton of money on Ads that are not coverting then you know if your site speed is slow as rock, then your just burning cash.. You need a site that converts.. (or at least thats what they say) So, Iv hired shopify specialists several times over the years and paid out the nose for Website Optimizations. Well, NOT ANYMORE.. Thanks to this APP. Literally, within 2 hours of installing this app my GOOGLE scores are in the 90% Range for all 4 Scoring Matrix's. This APP is wonderful. I highly Recommended -- here are my speed site score link if youd like to see performances https://pagespeed.web.dev/analysis/https-mattressxperts-biz/kmk6rwjulq?form_factor=desktop .. Get it! it works
