It recommends measuring customer satisfaction with social media experiences through on-site surveys on controlled, sponsored, and viral social media. A social influencer model can identify key customer personas. The value of social media should be calculated by linking social influences to future behaviors and revenue. Measuring the right metrics will determine business priorities and show what drives loyalty, conversion and word-of-mouth.
