Web-only retailers trail multi-channel retailers in driving sales from repeat customers using analytics and optimization tactics, according to WebTrends' "2005 Online Retail Holiday Readiness Report," based on a survey of 242 online retailers, including internet-only, internet-and-catalog, internet-and-store, and internet-catalog-and-store retailers, reports DM News.

Internet-and-store retailers and internet-only retailers trail the others in testing site content and marketing promotions, with 59 percent and 48 percent, respectively, having no plans to do testing, in contrast to 41 percent of internet-and-catalog companies and 31 percent of internet-catalog-and-store operations.

Internet-only retailers are similarly averse to segmentation, with 44 percent of them saying they don't know whether segmentation is important to the success of their holiday season, that it is minimally important, or that it's not important at all.
