Razorfish, a digital marketing agency, has developed a scoring system for evaluating how a company is discussed in Facebook, YouTube and other social media.
From Online Media Daily: "The basic formula for deriving a brand's SIM
Score involves dividing "net sentiment" for a brand by the net
sentiment for its industry group. (Net sentiment = positive + neutral
conversations – negative conversations/total conversations.)"
If tracked over time, this index can illustrate broad trends in your social media progress. However, implementation could be difficult and time-intensive. You have to ensure that "positive," "neutral" and "negative" are clearly defined and applied consistently – no small task. Also, what's a "conversation?"
This formula weights comments from everyone equally. This may not be appropriate in social media communities where there are individuals whose comments are more influential than others.
In any case – however you do it – do count and analyze your comments regularly and consistently to track your ability to maintain and grow a social network.
