2010 marked a year of significant changes in the Internet landscape (primarily with the growth of social networks and mobile devices); these changes forced retail executives to think hard about the implications for their web businesses. 2011 will be marked by an even more disciplined approach toward multichannel retailing, investments in mobile and tablet presences, and scaled-back expectations for the role of social networks in retail. Retailers will also find opportunities in launching marketplaces (similar to Amazon.com's) and in investing in emerging tactics such as conversion marketing.
