Desktop, Tablet and Mobile Compatible
Up until now the majority of my sites have been designed and built to ensure the desktop version also works and displays well on a tablet or mobile device. I have reasoned that unless the customer is aware that a large percentage of their target audience is accessing their services via mobile then it was probably an unnecessary expense to build a mobile specific version of the site.
Adaptive Website Design
Since April 2015 I have had to take a different view. In April 2015 Google changed it's mobile search algorithms to give a listing preference to mobile specific sites. In short if you want your site to appear in the listings when someone searches for your company or services from a mobile device, you will have to have a mobile specific version of your site available.
Business Catalyst allows me to design and build desktop, tablet and mobile versions of your site alongside each other with no need for additional URL's or hosting. When a user visits your site the site will automatically detect whether they are on a desktop, tablet or mobile and serve them up with the appropriate version of your site. This is known as Adaptive Website Design.
When Google lists and ranks your site they are able to detect that you have a mobile friendly version of the site and will list and rank you accordingly.
