What is "Mobile Ready"?
Websites which are "Mobile Ready" are also known as "responsive". To see if your website is mobile ready, the easiest way is to shrink the width of your browser and see how your website reacts. If it scrolls off the screen, chances are it's not mobile ready and your customer base will be frustrated when attempting to use it.
With the majority of users now accessing web content via their mobile devices rather than their desktop or notebook computer, responsive web sites are becoming mandatory as people become used to accessing their data on-the-spot with their mobile device.
