Affiliate marketing is a marketing arrangement in which affiliates receive a commission for each visit, signup or sale they generate for a merchant. This arrangement allows businesses to outsource part of the sales process. It is a form of performance-based marketing where the commission acts as an incentive for the affiliate; this commission is usually a percentage of the price of the product being sold, but can also be a flat rate per referral.
Affiliate marketers may use a variety of methods to generate these sales, including organic search engine optimization, paid search engine marketing, e-mail marketing, content marketing, display advertising, organic social media marketing, and more.
