Check out the Counting Crows (CC) Facebook strategy. CC fans want to know when their favorite band is touring. CC will only reveal that information when enough of their fans share their Facebook application. Fans who share with 10 or more friends are entered to win free tickets. Those who participate are signed up for updates from the band. The strategy is brilliant:
1) It’s simple. Anyone can understand it immediately.
2) It’s effective. Motivated fans want to know the information; they can participate quickly and easily for free.
3) It’s “viral.” Fans are provided an incentive for sharing.
I like that model, especially because the big prize – and the incentive for sharing – is access to information. The promotion serves as a good reminder that revealing information can have a greater impact than a traditional give away.
