Almost 84 percent of online retailers plan Cyber Monday promotions this year, an increase of more than 10 percentage points from the 2007 holiday shopping season, a new survey says.

The survey, conducted for Shopzilla.com for Shop.org, a unit of the National Retail Federation, and released Monday, found that online retailers had an array of strategies, including specific deals (38.8 percent); e-mail campaigns (32.7 percent); one-day sales (24.5 percent), and free shipping (24.5 percent).

The Monday after Thanksgiving, dubbed “Cyber Monday” by Shop.org three years ago, was coined to describe a spike in online shopping that day.  

"As shoppers focus on price this holiday season, online retailers will be extremely competitive to offer the very best deals," Scott Silverman, executive director of Shop.org, said in a prepared statement. "Americans who are looking to put a dent in their holiday shopping will be able to find thousands of bargains on Cyber Monday."

A separate survey, conducted by BIGresearch, found that 70.0 percent of young adults 18-34 with Internet access will shop at work and that men are more likely to shop from work than women (60.3 percent versus 51.5 percent).

In addition to pushing online sales for Cyber Monday, the study found that more than one quarter of retailers plan to increase their online marketing of promotions for Black Friday, the day after Thanksgiving when retailers presumably turn a profit for the year, or go into the “black.”

The BIGresearch survey polled 8,758 consumers on November 5-11. The Shop.org/Shopzilla survey polled 60 retailers from October 1-20.
