"Many small businesses have adopted social media marketing, and it’s typically an easy choice for them to use Facebook—with its 750 million members and counting, not to mention easy self-serve ad sales system—when they do so.
According to October 2011 research from email marketing software firm Constant Contact, Facebook was the most commonly used social media tactic for small businesses to connect one-on-one with their customers or prospects. Among all online methods, it was second only to email.
Facebook’s popularity goes along with its perceived effectiveness. Among small businesses that said social media marketing in general was effective, 83% said that Facebook was at least moderately so. By comparison, 46% said the same of Twitter, the second-ranked social channel."
