In some cases, the purchaser arrives at a page where the affiliate cookie gets set, then leaves and makes a purchase via the PPC channel sometime before the affiliate cookie expires. Other times, the purchaser may click a PPC link, fail to make a purchase, but later purchase via an affiliate link. In both scenarios, the affiliate marketing channel played a part in the sale, but the role was different.
Sellers are responsible for claims they make about their products and services. Third parties - such as advertising agencies or website designers and catalog marketers - also may be liable for making or disseminating deceptive representations if they participate in the preparation or distribution of the advertising, or know about the deceptive claims.
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.
