An affiliate program is a partnership between a business and individuals or entities (affiliates) where affiliates promote the business's products or services through various channels, such as websites, social media, email, or other marketing platforms. Affiliates are provided with unique tracking links or codes, which they use to drive traffic or referrals to the business's website. When a referred customer makes a purchase or completes a desired action, such as signing up for a service or filling out a form, the affiliate earns a commission or other predetermined rewards. Affiliate programs are a cost-effective way for businesses to expand their reach and increase sales, while affiliates have the opportunity to monetize their online presence and marketing efforts.
