I am not going to pretend I know a ton about social media. That is why I work with people who know more about the subject than I. But I like measures. I like to know that my time and energy are paying off. This quick slide show is a very simple way to measure sales results from social media. It is all about establishing a baseline.
P.S. the link did not work out as I thought it would. You have to look for the video about Social Media Measures. Good luck!
