From April 21 Google will begin to implement a new search rankings algorithm.
They are going to use mobile-friendliness as a factor in rankings. With sites that are mobile-friendly getting a listings boost.

Here’s what Google recently posted on their Webmasters blog

Currently Google search results return a label next to the listing stating if the site is mobile-friendly. This helps users to identify sites that are going to display well when viewed on mobile and deliver the best experience.

How does Google check for mobile-friendly design?

Google check for various criteria when assessing mobile-friendly design, these include:

• Use of plugins such as Flash (which isn’t generally compatible with mobile devices)
• Readability of the text – so that a user can browse the site without having to use zoom
• Layout – the content size is appropriate for the mobile screen without having to scroll horizontally
• Positioning of interactive elements – this makes sure that links for example are easily clickable by the user
