Small business "likes".

Marty,

I have helped clients configure promotions and they run the spectrum. Some of done things as simple as offering a chance to win an item that has broad appeal and others offer discounts or coupons on services. For example one publishing company offered a chance to win an e-reader (I believe it was a kindle fire) and the drawing would be conducted after the page reached 20K likes.

Like I mentioned others would offer discounts or coupons for their services. These contest are typically administered through a custom application that is fangated. If you aren’t familiar with a fan gate, its simply an application on the Fan page where users have to like the page in order to get access to some kind of content. For instance on the kindle fire giveaway, visitors would have to like the page in order to get access to a simple email entry form in order to be entered to win the kindle (notice the client was also building an email list; Sweet!)
