If you want to uncover more merchants who partner directly with affiliates, just keep your eyes open. When you see affiliate links, do a quick search to see if the related merchant runs their own program. (We came up with the list above by reviewing a few of the bigger affiliate marketing blogs and investigating the most prominent affiliate links on those sites.)
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.
