An affiliate program, also known as affiliate marketing or partner program, is a performance-based marketing arrangement where a business rewards one or more affiliates for each visitor or customer brought about by the affiliate’s marketing efforts. In this model, affiliates promote a company’s products or services through various channels such as websites, blogs, social media, or email marketing. When a potential customer clicks on a unique affiliate link and makes a purchase or completes a desired action (like signing up for a newsletter), the affiliate earns a commission. This commission can be a percentage of the sale value or a fixed amount per action. Affiliate programs benefit businesses by expanding their reach and only paying for results, while allowing individuals or other businesses to earn money by leveraging their audience or marketing skills without creating their own products or services.
