Social media’s empowerment of the individual means anyone can be an influencer. That presents an opportunity and challenge to every social impact organization: What does influence mean and how do you harness it? To explore this question, we conducted an exhaustive study of more than 2,000 digitally engaged cause-supporting adults. The study provides insight into the habits, behaviors, and motivations of these individuals, as well as information on how to engage them to produce greater support and action on behalf of causes.
