Web analytics on all of the sites managed by Phosphor shows a big jump in mobile traffic in the last year, with iPads and iPhones topping the stats.

Most sites have increased mobile traffic from 0-1 percent of all traffic in 2009-2010 to 3-4 percent in 2010-2011.

iPad visits in particular have grown, and in many cases iPads show the highest numbers of visits, about double the number of iPhone visits, which is the next most popular over the last year.

This reflects stats which show that  tablets have overtaken smartphones in terms of mobile commerce. One in 10 tablet owners reported using their device for browsing or buying online every day, vs. 6% of smartphone users, and nearly 1 in 4 had made at least 6 purchases in the past 6 months.
