Robert Pease, Vice President of Marketing at Gist, Inc., argues that companies must listen to online conversations to understand customer needs and sentiments. He outlines steps for engaging in online communities through contributing helpful content, amplifying others, and responding promptly while avoiding direct sales pitches. Companies should target influential online voices, build a pool of shareable content, and measure success based on follower growth, conversions from leads, advocacy, and referrals rather than just marketing activities. While challenging, online engagement through communities can blur traditional roles and become a core marketing strategy.
