Do You Need to Have a Target Market?

i got the idea from one of john jan's books. And he talks about how they really don't want to do business with a client unless they're sure they're going to end up with a good chance at a referl. So that's why you want to make sure you're goig to be able to help somebody, because these days, the referrals are very important. But allan dib, this is the marketing book podcast, and i'm required by law to ask at least one question about social media. Can you put it into perspective for us and help us see where it fits into an overall marketing strategy?
