Oh, I must have misunderstood. I thought you were talking about getting people to sign up for your affiliate program.

You want people to sign up for other people's affiliate programs so you can make a cut of the money? Good luck. There are ways to do it without being annoying (ie; spamming), but they involve a lot of work and I don't know how successful they are.

Anyway, if you have to ask how to recruit webmaster referrals then you probably shouldn't be in the business of finding them in the first place.
