Great post Perrin! I think one of the biggest problems that rarely gets talked about are the nexus laws that restrict certain states from being accepted into an affiliate program. Currently, those states are Arkansas, Colorado, Connecticut, Georgia, Illinois, Kansas, Maine, Michigan, Missouri, Nevada, New Jersey, New York, North Carolina, Ohio, Tennessee, Pennsylvania, Rhode Island, Vermont, Washington, West Virginia.
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.
