Brand advocates are consumers who actively promote the brands, products and services they love and provide marketers with a volunteer army of supporters who disseminate recommendations to friends and family.

Social media influencer and advocacy company Zuberance found, in a January 2012 study, that US internet users are making more recommendations than ever before, across a variety of industries. On average, the US internet users studied by Zuberance made 9 recommendations per year.
