Social media marketing refers to the process of gaining website traffic or attention through social media sites. Social media marketing programs usually center on efforts to create content that attracts attention and encourages readers to share it with their social networks.
Social media is a way for people to communicate and interact online. While it has been around since the dawn of the World Wide Web, in the last 10 years or so we've seen a surge in both the number and popularity of social media sites. It's called social media because users engage with (and around) it in a social context, which can include conversations, commentary, and other user-generated annotations and engagement interactions.
Whether you are running a small, local operation, or heading a global, enterprise-level effort, the statistics above make it clear: Your customers are online. They are interacting in social channels with their friends, colleagues, and other brands in search of information, recommendations, and entertainment. If your company is not around to answer, a competitor will be. In doing so, your competitor will quite likely take away the customer at hand, along with anyone else listening.
