What is the true value of all of those Facebook fans you've been collecting? Some social media specialists have done the math and it turns out that on average each fan is worth about $3.60 a year.
The study does not specifically look at bands or fans of music, but its' clear that not all fans and brands are created equal. In its study of 41 million Facebook fans, marketer Vitrue found a wide variety of impression-to-fan ratios. Some generated just .44 impressions per fan, while another saw 3.6 impressions.
