This document summarizes research on integrating word-of-mouth (WOM) measurement into consumer insights. It discusses findings from WOM surveys in the US, UK, and Australia, which show that most WOM is positive and occurs offline. The research also identifies "influencers" who engage in twice as much WOM as others. Finally, it describes how WOM questions were added to the IPA TouchPoints survey to provide a more holistic view of media influence and better understand influencer behaviors.
