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.
The definitive advantage of affiliate marketing is the fact that it is a pretty easy industry to join, namely because there are no barriers to entry. It’s just the matter of your decision. All you have to do is to create an affiliate marketing website (but you can also become an affiliate marketer without a website), choose a compelling niche and finally a particular product or products (goods) that are relevant for you to market. Then you simply sign up for a selected affiliate marketing program, and you’re ready to start.
As search engines have become more prominent, some affiliate marketers have shifted from sending e-mail spam to creating automatically generated web pages that often contain product data feeds provided by merchants. The goal of such web pages is to manipulate the relevancy or prominence of resources indexed by a search engine, also known as spamdexing. Each page can be targeted to a different niche market through the use of specific keywords, with the result being a skewed form of search engine optimization.
