But we do have the technology to make it more precise and this is exactly where big data comes into play. Millions of customer journeys can be described to an artificial intellect and this intellect can reduce them to a simple number -- how much impact each step has on goals, most specifically, revenue. This is generally done through the process of marketing attribution which measures precisely how much every single marketing effort tips the scale in favor of success.
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]
