Thanksgiving is almost here, and as consumers plan their turkey feasts, marketers should be planning their Black Friday and Cyber Monday campaigns. According to a new survey from Shop.org, online Cyber Monday sales should be strong this holiday season, with more than half of Americans who access the internet at work planning to do some internet shopping at the office.

Shop.org says that 54.1 percent of Americans with internet access plan to shop online during their lunch breaks (or the workday) on Cyber Monday. This translates into 70.1 million people who will look for gifts online, and the survey does not consider Americans who will shop from home. More than half of these workers are men, and the majority of workday shoppers are young adults – between 25 and 34 years of age.

Marketers hoping to reach these potential customers should note that the competition to catch ecommerce spend will increase this Cyber Monday. Nine out of 10 retailers surveyed (88.2 percent) say they are planning to offer special promotions to mark the day. This represents a considerable increase over 72.2 percent of businesses that planned Cyber Monday deals last year.

Joan Broughton, interim executive director of Shop.org, suggests that Cyber Monday is poised to be a major ecommerce event this year. “Today, Cyber Monday has become such a crucial component of the holiday season that many retailers – and shoppers – don’t remember the holidays without it. And just when we think that Cyber Monday can’t get any bigger, it does,” he says.

Shop.org is not alone in this prediction. A recent report from BDO USA, reported by Brafton, indicates that CMOs expect sales to skyrocket this Cyber Monday, as well as Black Friday.
