As with offline advertising, industry participants have undertaken numerous efforts to self-regulate and develop industry standards or codes of conduct. Several United States advertising industry organizations jointly published Self-Regulatory Principles for Online Behavioral Advertising based on standards proposed by the FTC in 2009.[109] European ad associations published a similar document in 2011.[110] Primary tenets of both documents include consumer control of data transfer to third parties, data security, and consent for collection of certain health and financial data.[109]:2–4 Neither framework, however, penalizes violators of the codes of conduct.[111]
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]
