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.
Know when (and when not) to use Viglinks and Skimlinks. If you applied to an affiliate program but were denied, you might be able to still be an affiliate for that advertiser through a secondary affiliate program like VigLink or Skimlinks. Basically, they themselves are affiliates and will split their affiliate commission with you if you put their affiliate link in your content for an advertiser. Obviously, the commission rate is lower for you in this case, so if you ever are accepted into the advertiser’s affiliate program directly, immediately switch from using VigLink / Skimlinks affiliate links to your own.
When it comes down to brass tacks, there are some important steps to be taken to succeed as an affiliate marketer, and an overall framework that needs to be followed. But before getting into that, it's important to get a lay of the land and look at the macro aspects of marketing and buyer mentality before being able to leverage any of that psychology to sell commissionable products or services.
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.
