RAGAN – July 7 - Facebook users are more likely to use a brand's Facebook app if they find out about it through private messages and newsfeed posts, a recent Massachusetts Institute of Technology study found. Viral strategies are 10 times more likely to bring in new users than banner ads and twice as effective as emails. MIT professors Sinan Aral and Dylan Walker offered an entertainment app to random samples of users. Some users got a version of the app that used "passive" messaging—that is, the app posted messages to users' Facebook walls every time they used it. The passive version led to 246% higher user adoption compared with a version that sent no automatic messages, but were 7% less active with the product.
