You have to play by the rules.
Promotions and giveaways are great ways to interact with your fans and gain more visibility for your business on Facebook and other social networks. But if you are going to do a contest, it is important to play by the rules. Developing a social media promotion takes some research and planning before you can share publicly that you are giving something away.
Before you launch a Facebook promotion, check out Facebook’s rules and guidelines https://www.facebook.com/page_guidelines.php. There are certain things you are and are not allowed to do on Facebook. For example, you are not allowed to collect entries through Facebook comments or photo uploads, but you can use an official Facebook app to announce and run your contest. As the admin of a page, it is your responsibility to read and understand these rules before starting a contest or giveaway on your page. Facebook has the right to reject or remove any page that does not follow their guidelines.

5. Measure the results
By taking the time to prepare your contest and make sure that you have followed the guidelines set by Facebook, your contest or giveaway may be a successful promotion for your business or company. You could gain valuable interaction and feedback from your current customers and even gain some new customers and fans.
