How to make mobile friendly blogs?

Yes, Google is going to roll out an algorithm update on Mobile usability of a site. Now, don't think that, Google will not index non-mobile responsive sites. Google will still index them but it will not rank let them higher in searches made by handheld devices.

How to make your site mobile responsive

Instead of creating a mobile friendly version of your site on a different subdomain like m.example.com, I recomend you to install a responsive theme on your blog. A responsive theme automatically adjusts its size according to the screen size of the device.

For making Blogger blog mobile friendly :

1. Firsly, you have to choose and download a mobile responsive template for you blog. Some of the free templates are :
