Social media, as part of your marketing mix, offers an inexpensive opportunity to engage more directly with your various audiences, often on a one-to-one level. The rewards can be great, especially if these efforts help convert your audience into company or product evangelists. Social media requires a higher level of engagement and interaction than more static marketing vehicles, so sustainability and commitment are critical.
