For those skeptics who don’t believe that Social Media has a measurable impact:

According to a study conducted by research firms Chadwick Martin Bailey and iModerate Research Technologies, two-thirds (67%) of consumers who follow brands on Twitter are more likely to buy those brands after becoming a follower, and 51% of Facebook fans are more likely to buy after becoming a fan. Moreover, 79% of those who follow brands on Twitter are more likely to recommend those brands after following them, and 60% of Facebook fans say the same for Facebook.
