The Forrester Groundswell Awards inspire marketers worldwide with examples of the best of social marketing.

In addition to sharing our 2015 winners, this report provides tips for B2C marketers to incorporate within their marketing strategies. B2B winners are discussed in the report "What You Can Learn From B2B Forrester Groundswell Winners."
