There are three primary ways to locate affiliate programs for your website:

1.  Consult affiliate sites like clickbank.com or cj.com.

2.  Work with a large affiliate network that provides the platform for dozens or even hundreds of  advertisers.

3.  Research individual merchants to see if they offer an affiliate program

Through these companies, you can market the whole merchant site or a specific product from the central site. The activity you generate is tied to your personal affiliate code, and the respective merchant sends you a commission check.
