Eu recomendo, as métricas para computador ficaram ótimas. As métricas para celular foram otimizadas mas ainda falta melhorar o desempenho e acessibilidade, voltarei em algumas semanas para dizer mais !

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

Hi Anbu Clothing, for old subscribers, we didn't raise the prices at all. Please write us an E-Mail and we will get this sorted.

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.

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

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!!!!

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!

Dear Karen, first of all, we didn't charge your store any single dollar. Thus, I don't understand why you didn't ask our support team through E-mail or Slack about the usage fees, before leaving a bad review. There is a 7 day trial but you uninstalled our app after 5 minutes - thus your review doesn't seem to be based on experience. Please get back to us and I am happy to explain everything in detail Update: sorry, I just tried to help. A 1 star review for not using our app after all, without contacting us to explain it just doesn't seem fair. The 7 day trial is completely free up and there are no charges in that period except if you pass 10.000 requests. Then a $4 charge applies up to a maximum of $40 - which equals 100.000 requests

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 is AMAZING!! My website speed is so much better now according to Google PageSpeed Insights. Even on mobile it loads very fast (I used to be in the red zone all of the time, even with the use of other page speed booster apps). Now I only use this app and I'm very happy with the results. Thank you for doing such an amazing job!
