Cyber Monday spending increases 33%

ARMONK, N.Y. — Coming off a Thanksgiving weekend chock full of sales gains, it appears retailers also fared well on Cyber Monday, according to a new report by IBM.

Online sales were up 33% over 2010, while consumers' average order value increased 2.6% from $193.24 to $198.26. Additionally, mobile sales reached 6.6%, compared with 2.3% in the year-ago period, with 10.8% of people using a mobile device to visit a retailer's site, up from 3.9% in 2010, IBM said.

"Cyber Monday was once again the big winner for the Thanksgiving holiday shopping season, with a record number of consumers focused on finding the best online deals," IBM Smarter Commerce chief strategy officer John Squire said. "Retailers that adopted a smarter approach to commerce, one that allowed them to swiftly adjust to the shifting shopping habits of their customers, whether in-store, online or via their mobile device, were able to fully benefit from this day and the entire holiday weekend."

The findings were based on IBM's fourth annual Cyber Monday Benchmark, which tracks more than a million transactions a day, analyzing terabytes of raw data from 500 retailers nationwide.
