Cellcom is a local cell phone provider in Wisconsin and the Upper Peninsula that started a Facebook page in 2009 to promote customer appreciation events. Through a series of promotions from 2009 to 2011, they learned that offering prizes with mass appeal, balancing the effort required to enter with the value of the prize, promoting contests outside Facebook, and allowing adequate time for entries increased fan engagement and growth. Maintaining a large Facebook following provides benefits like a broader communications channel for promotions and improved customer service.
