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.**
