If you think the surge in smartphone adoption among U.S. consumers removes the need for a mobile-friendly version of your website, please reconsider. Especially if your current site uses Flash, is image heavy, or if you sell online.
According to an April 2011 report by ComScore, there were 234 million mobile consumers in the U.S. at the end of February 2011. Of those consumers, only 69.5 million (just under 30%) were using smartphone devices.
While that number is below the projected adoption rate of 40% forecast in a March 2010 NeilsenWire report, it is plausible that the market will see a 50/50 split between feature and smartphone users by the end of 2011.
Age demographics and international traffic aside, by not integrating a mobile-friendly version of your website today, you’re making it very difficult for 164.5 million potential customers with feature phones to see you. True, by the end of 2011, that number will have shrunk – but only to 117 million potential customers.
If you’d rather engage these millions of potential customers than ignore them, Mashable has a great list of resources to get you started.
