You need to give people a social object, or they’re not going to talk about you. Just being there, or just delivering a good product, doesn’t cause a word of mouth conversation. You need to throw out something that is interesting and unusual enough that people want to talk about it.
Equally important is that it’s clear and simple enough that they can share it — it’s not too complicated to repeat.
Great examples: Krispy Kreme’s hot donuts, Zappos’ unlimited returns, Southwest’s amazing customer service.
What’s your social object? What have you given people to talk about?
