Hi the best ways that I used to recruit affiliates are 3.
1: make a blog, put all the news to work in SFI, put it on the net.
2: Do a site (there are several sites that you can go for free) and then use the systems offered by the network to put it on the search engines.
3: so much advertising online ad sites is free and for a fee.
These are the three systems I use and they work for me.
