Check out what competitors are offering and how they structure their affiliate programs because that'll be a good place to start. It's also what your affiliates are going to be comparing you to when deciding whether to endorse you or someone else. Remember, your affiliates have many options of products/services to represent so they're going to want to choose products that convert well and offer a decent payout.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
