In effect, VigLink works as the middleman between a publisher (blogger) and merchants by scanning the publisher’s content and automatically creating links to publishers that are chosen “in real time” based on their payout/conversation rates. This makes VigLink a very hands-off affiliate program for publishers who prefer to focus on content instead of managing their affiliate links.
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.[citation needed]
