It begins with an introduction that notes there are over 1 billion monthly active Facebook users, making it an attractive platform for marketing. The document then discusses relevant theoretical background, specifically how face-to-face communication allows for reciprocal influence. It identifies key communication conditions that impact effectiveness: structure, climate, and power. Finally, it discusses communication strategies like frequency, direction, modality, and content and hypothesizes that these strategies moderate the relationship between conditions and a fan page's communicability.
