How is it done

PageSpeed Guru speeds up your shop by removing renderblocking caused by stylesheets and javascript.

Since each lookup of an external ressource like a stylesheet or a javascript can take anywhere from 0.1 second to several seconds. Removing renderblocking will always speed up your shop.

  1. PageSpeed Guru inlines your CSS.
  2. Depending on your shop, the theme, your apps and how your shop is set up. PageSpeed Guru tries to: a. Load your scripts with ASYNC / b. If that doesn't work (re: happens when scripts have interdependencies) it tries to load you scripts with DEFER. / c. If a and b doesn't work it inlines javascript (re: this always works) but is uggly.

** If you have 10 stylesheets and 10 javascripts you have a minimum gain of 20x0.1 ~ 2 seconds. and so on.**

The app doesn NOT do anything special. It only reduces the images' quality, making them blurred, and very hard to see. It changed the structure of the website without consulting us first. IT CHANGED THE NUMBER OF PRODUCTS PER ROW AND ADDED FILTERS, WHICH WE DID NOT WANT. Completely useless app. + Waste of money!!! We are interested if they can speed up the site without messing it up. If not, we are expecting a refund.


Didn't work for me. Google side speed actually showed it was slower. Hopefully you do the right thing and will not charge me.
