Facebook has over 4 million users who are increasingly older than 26. It is now the 6th most visited website in the US with over 54 billion page views per month. The large number of applications (over 4000) and high user engagement (85%) means Facebook provides many opportunities to market brands and engage customers through applications, groups, and other features. To successfully use Facebook for business, one should start with clear objectives and build a compelling application with ongoing improvement, measurement and user nurturing.
