Inline your Critical CSS to eliminate render-blocking resources. This will speed up your store.

With Critical CSS, the visitor gets the base styling as quickly as possible; because it’s right there in a <style> element in the document’s <head>, there’s: no extra request to the server for the stylesheet & no waiting for the requested styles to load in and render. The below-the-fold, or non-critical, styling is then loaded in the background to avoid render-blocking.

KRAZY! That's all I can say. What a totally brilliant app. For a measly $10 our Pagespeed score went up >25%. How can you beat that? Try the app – you'll see. And then once you experience what we've experienced – continue to periodically rerun the app from time to time, to sort out changes that you make to your store. Possibly the best $10 investment ever!

We’re sorry that the app didn’t work out for your store.

However, we’d like to clarify that the app does work as intended. In this case, there was a specific compatibility issue between your store and our app, which is why it didn’t function as expected for you. This was an isolated case, as many businesses successfully use our app.

Regarding the timeline, you first reached out on January 30, and after confirming the compatibility issue, we informed you right away. Your refund was processed by Friday, February 7.

We apologize for any frustration this may have caused and appreciate your feedback. Thank you for giving our app a try.

"Instant pagespeed increase for $10... yeah right?!" That's exactly what I said when I saw this app but thought I'd give it a go anyway, SO GLAD I DID! Having spent a few days trying to boost the speed of our store and only getting marginal gains my research lead me to this app. The install was super easy and instantly flagged up some unseen errors in my CSS (blame my template creators for that!), once I fixed those the app did its thing and added a snippet to the head for the critical css, I could then confidently move all the remaining stuff to the end of the body. I ran a pagespeed test before installation on the different page types and again after installation (plus cache clearing). I'm happy to report a very significant pagespeed increase across all pages! I had a few noob questions and the support was spot on and helpful. Honestly, this is a seriously good value for money app and really worth trying!

A quick and easy way that made our site snappier with first visits and slower connections where the browser needs to initial cache. This did not make lighthouse faster for us, perhaps a misconception of what critical CSS does, but it does make real world load time faster and lowered our blocking time.

One day since install opinion:
This helps us stream line our CSS and in conjunction with some other fixes we were able to get our page speed score up from a 28 to a 90(at its peak on mobile)! Great customer service, alex responding quickly and was ready to help however we needed. This is a one man team and he's doing great job!
