One of the social media networking websites many people have heard about, but know little about, is Foursquare. The concept is simple: you “check in” at various places of business and your friends who also use Foursquare will see your check ins. Why should you care? For some business owners it provides no benefit since customers never visit their physical location (AC repair, plumber, etc.), and Foursquare is all about locations. However, for businesses with customer traffic, we can build a social MARKETING program around Foursquare.
