Social media plays an important role in marketing for most businesses. The main difference in social media marketing is the feedback received from the customer. It provides a forum for listening not available from other media. The biggest mistake that companies make is to set their social media up and never revisit, improve, or monitor it. LinkedIn and Twitter are the two most commonly used outlets. Analytic software can identify links from social media to the company’s Web site, which provides data on how effectively the social media environment targets interested patients.
