Pretzel Crisps Grows its Facebook Fan Base With Coupons

This communication strategy isn't limited to Facebook, either. Pretzel Crisps uses Twitter for what it calls "social sampling."

"We use Twitter to actively listen to conversations, to target people who are in need of a little snack," Harty says. "Those can be dozens of different types of conversations we're searching for within very specific geographies. We reach out to them and say, ‘I heard it's your birthday, I'd love to bring you a gift basket,’ or ‘You're having a movie night? Pretzel Crisps go great with humus for a healthy snack alternative.’ There are dozens of different ways to engage like that and we've seen great success."
