As part of my Christmas week re-evaluting efforts I am in the process of redeveloping my website. My stats made me aware that almost 25% of my visitors have done so on a smart phone. That lead me to add to my list of to-do's a mobile version of my site. I wouldn't have even considered it if it was under 10%. I plan on having the landing page offer you the visitor a web or mobile choice. This will also help me see if they actively choose the mobile version.
I strongly believe it will help my brand image among prospective customers. You could wait and see, but leaders accept the obvious and do it now. It's all about making it easier for customers to find and benefit from your assistance. If you've been following my opinion for any period of time you know my strategy is to lead not follow.
Have you checked your stats on this lately? What are your customer's actions telling you?
