Jamie Turner dives into social ROI:
We've covered a lot of ground here: the three categories of social media measurement and the single most important formula in social media. But the bottom line is that, as businesspeople, we don't use social media to be social, we use social media to grow our business. And if you use the program outlined above, you'll be able to prove the value of social media on a campaign-specific, ROI basis.
Good luck with that.
