Disable CSS bundle and Authorization CSS Blocking Resources

Render Blocking CSS resources always affect web site’s loading speed and make our site slower to load. And this is also bad for SEO, because search engine prefer fast loading website to serve then on search engine result page. Google’s new project is Accelerated Mobile pages (AMP) project whose main aim is to divert search traffic to fast loading website. So we must make our Blog site faster by all means.

As a new user you might be confuse about Render Blocking CSS resources. Generally Render Blocking JavaScript stops building DOM tree while parsing the HTML markup. When website loads in browser then it render a page and for rendering it has to build the DOM tree by parsing the HTML markup. And during this process render blocking CSS resources encounters the normal rendering process of a page. As a result it stops and execute before parsing the HTML markup.

So if you site containing multiple render blocking CSS resources then your site will take longer time to load. To check render blocking CSS resources just visit below URL and test your Blog site.

If you are using default Blogger template then you can adopt a safe procedure. Though clickable CSS resources count as render blocking so we will add the CSS bundle file inside style tag. From your Blog page source click on clickable URL and all CSS bundle file will open in new tab. And copy the whole CSS script and paste it in a notepad (Don’t paste the CSS code in any Rich text supported text editor like Microsoft Word).

<link type='text/css' rel='stylesheet' href='https://www.blogger.com/static/v1/widgets/2973171168-css_bundle_v2.css'/>
<link type='text/css' rel='stylesheet' href='https://www.blogger.com/dyn-css/authorization.css?targetBlogID=XXXXXXXXXXXXXXXXX&zx=c438423a-a8f4-4cca-b115-1e1bcd093875'/>
