According to a study by ExactTarget and CoTweet, over one-third of Facebook users who become fans of businesses do it to show their support for the company to others. Around the same number of Facebook business fans do so for discounts, so keep them loyal with super deals and great customer service and they’ll brag about you and introduce you to others.

Interestingly, 43% of Facebook users say they “Like” or are fans of at least one brand on Facebook.
