There is some evidence that the dialogue appears to help the business performance of companies by influencing, for example, product sales, consumer attitudes, and consumer decision-making. This chapter examines the evidence, with a particular focus on on-line consumer product reviews. Also investigated is the role trust plays in how marketing works in the social media. Managerial implications and research directions are indicated. © 2015, IGI Global.
