Affiliate marketing is a performance-based marketing strategy in which businesses partner with affiliates or third-party publishers (affiliates) who promote their products or services in exchange for a commission for each sale or lead generated through their efforts. Affiliates promote products or services through various channels such as websites, blogs, social media, email, or other digital platforms, using unique affiliate links or codes to track referrals and commissions. Affiliate marketing programs typically provide affiliates with marketing materials, tracking tools, and commission structures, and they offer businesses a cost-effective way to reach new audiences, drive traffic, and increase sales without upfront marketing costs.
