Are you ready for “couch commerce?” The holiday buying and giving season is almost here and the next big change in online shopping is coming to town. By ready, we're talking about mobile-ready. If you have a web presence and sell any of your products or services online, being mobile-ready needs to be a high priority.

Last year, customers spent $35.3 billion at retail sites. That was a 16 percent increase over holiday 2010 and exceeded projected growth of 15 percent by an increase of 1 percent which, in dollars, is a huge amount.

Looking ahead a few weeks, it appears that 2012 slows no sign of slowing down. But the biggest change is in how customers are shopping and buying. More and more e-commerce is occurring on smartphones and tablet computers. Is your website optimized for those mobile customers? If not, you may be missing out on your share of those billions of dollars in sales. Like it or not, more and more shoppers do a little “show rooming,” looking at actual products, and then retreat to the sofa, tablet in hand, for a bit of laid-back couch commerce.
