Each time a fan “likes” or “comments” on a Facebook page, a post is created on the fan’s respective wall and on their friends’ news feeds. Since the average Facebook user has 130 fans, this means your brand has the potential to be exposed to 130 people for every like or comment that your page receives.
Not only will their friends see your business name, these interactions effectively serve as personal endorsements of a brand from the people we trust most, our friends. This free visibility is invaluable, and each line item has a link back to your fan page. Because of the viral nature of its pages, the best way to grow and maintain a strong fan base is by posting compelling content that continually elicits the responses of your fans.
