WebSponsors offers a large number and variety of Pay per Lead advertising possibilities.
Most offers are free, making it relatively easy to get people to sign up.
Websponsors is nearly essential for anyone operating a Free Stuff page. You earn just as much on the ads in your Free2Try site as you earn on ads in web pages you design yourself. The Free2Try web site makes it very easy to promote all the ads that WebSponsors has to offer. I have received monthly checks from WebSponsors for more than a year now. I could earn much more if I promoted some of the ads more aggressively, which I have plans to do.
