There are two easy ways to optimize any WordPress blog for proper display on mobile devices:
1 – Either replace your current theme with a responsive theme or modify your current them to make it responsive.
In a nutshell, a responsive theme detects the type of device being used to view the blog and adapts itself on the fly to properly display the blog’s content on the screen.
Regardless of whether the visitor is using a computer, a tablet or a smart phone, a responsive theme will ensure that everything is easily viewed and read.
A mobile plugin will detect when the visitor is using a mobile device and ditch the desktop theme altogether and display the blog using a mobile theme instead.
