You’ve got to hand it to Google for creativity. It created the local business referral representative program to enlist stay-at-home moms, college students, and others to get better data about local businesses and build AdWords awareness. (I was told by Google that the response to the program had been strong.) Now Google has developed the “Google Online Marketing Challenge.” According to the site, “student groups will receive US$200 of free online advertising and then work with local businesses to devise effective online marketing campaigns.”
