Affiliate programs are marketing arrangements in which businesses reward individuals or other companies (affiliates) for driving traffic or sales to their websites through the affiliates’ promotional efforts. Affiliates earn commissions based on various performance metrics, such as clicks, leads, or completed sales. Typically, this is tracked using unique affiliate links or codes provided by the business. Affiliate programs can be an effective way for companies to expand their reach and for affiliates to monetize their online presence or influence.
