If you have advertised in the Internet and you have done your search, found out the right place for advertising SFI opportunities, where that site get the most traffic from specific target, people looking for business opportunities, which country and when you will find out through the sign ups. For me I don't have so much time to allocate in advertising, so I bought leads through SFI. Most affiliate sign ups come from India, UAE and a few from Europe, Australia and US
