Mobile marketing is all the rage, and while there are plenty of tactics to employ and signs of the arena’s growth in 2013, do you know who you should be targeting with these efforts? According to Forrester, there is, indeed, an answer. The firm segmented adult mobile phone owners in the U.S. into five categories: 1) Talkers (25 percent): mostly use their phones to talk; 2) Communicators (16 percent): use SMS at least once a week, may use MMS, IM or personal email monthly; 3) Connectors (15 percent): use mobile phones for work, utilize advance services at least monthly; 4) Entertainers (38 percent): listen to music, watch videos or play games at least weekly; 5) SuperConnecteds (48 percent): access mobile Internet at least weekly or do multiple activities monthly. It’s the last segment, SuperConnecteds, that’s the only audience mobile marketers should target, according to Forrester. (VentureBeat)
