Yah, if it's a blog site you might have to get the link in the sidebar. I try to avoid these because I don't want it on every page, but I'll take a few. You can join affiliate networks to sell leads, but I don't understand why people do that. I think that's more for people that are pushing paid traffic and want a quick partnership or something. I cut out the middleman and just email sites that would be interested in the leads. You'd be surprised what people will do when you simply ASK.
