Affiliate marketing

Affiliate marketing is an Internet-based marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate's marketing efforts.
Affiliate marketing is also the name of the industry where a number of different types of companies and individuals are performing this form of Internet marketing, including affiliate networks, affiliate management companies, and in-house affiliate managers, specialized third party vendors, and various types of affiliates/publishers who promote the products and services of their partners.
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, paid search engine marketing, e-mail 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.
Affiliate marketing—using one website to drive traffic to another—is a form of online marketing, which is frequently overlooked by advertisers.[citation needed] While search engines, e-mail, and website syndication capture much of the attention of online retailers, affiliate marketing carries a much lower profile. Still, affiliates continue to play a significant role in e-retailers' marketing strategies.

Successful affiliate programs require significant work and maintenance. Having a successful affiliate program is more difficult than when such programs were just emerging. With the exception of some vertical markets, it is rare for an affiliate program to generate considerable revenue with poor management or no management (i.e., "auto-drive").
Uncontrolled affiliate programs did—and continue to do so today—aid rogue affiliates, who use spamming, trademark infringement, false advertising, "cookie cutting", typosquatting, and other unethical methods that have given affiliate marketing a negative reputation.
The increased number of Internet businesses and the increased number of people that trust the current technology enough to shop and do business online allows further maturation of affiliate marketing. The opportunity to generate a considerable amount of profit combined with a crowded marketplace filled with competitors of equal quality and size makes it more difficult for merchants to be noticed. In this environment, however, being noticed can yield greater rewards.
Recently, the Internet marketing industry has become more advanced. In some areas online media has been rising to the sophistication of offline media, in which advertising has been largely professional and competitive. There are significantly more requirements that merchants must meet to be successful, and those requirements are becoming too burdensome for the merchant to manage successfully in-house. An increasing number of merchants are seeking alternative options found in relatively new outsourced (affiliate) program management (OPM) companies, which are often founded by veteran affiliate managers and network program managers. OPM companies perform affiliate program management for the merchants as a service, similar to advertising agencies promoting a brand or product as done in offline marketing.
