Affiliate programs are a great way to extend the reach of your program, but don't expect affiliates to make you millions of dollars without any work. Running an affiliate program requires a lot of time and investment in things like a script & domain to run the the program itself, plus banners, content, advertising, etc. Also, don't expect your program to be marketed as discretely as you would market it yourself.

That being said, affiliate programs are a great way to get your branding known to a larger group of people, so it is very realistic you will make more money. And you can start small, using your biller's built-in affiliate program and getting some marketing materials listed in a special area of your dating site's URL.
