Mobile Web traffic to high-traffic e-commerce sites grew more than 300% during the 2010 online holiday shopping season over levels registered during the same period a year earlier, according to a report by Conductor.

Among some 18 million visits to those five sites from November 1, 2010 to January 1, 2011, visits via mobile devices grew more than 300% over the same period one year earlier.

Traffic Distribution by Device

Among the sites tracked, Apple iOS devices accounted for more than two-thirds (67.1%) of visits to e-commerce sites during the 2010 holiday season.

Apple's iPhone accounted for 39.4% of traffic, followed by the iPad with 22.8%—though it was launched in 2Q10. Google's Android operating system was a close third (21.6%), followed by RIM's  BlackBerry (10.6%).

M-commerce Poised to Grow

As of December 2010, 47% of mobile subscribers were connected media users as of December—browsing the mobile web, accessing applications, downloading content, or accessing the mobile Internet via SMS—up 7.6 points from the previous year, according to separate research from comScore.

Meanwhile, smartphone ownership increased roughly 58% during the year, from 17% in 2009 to nearly 27% in 2010.

In view of those adoption growth rates, the trend toward mobile commerce is likely to continue, both in the use of mobile devices to obtain real-time price and product information—and in accelerating the shift in spending from offline to online, according to comScore.
