An affiliate program is a marketing strategy in which a company rewards its affiliates for driving traffic or sales to its website. Affiliates are given a unique link or code to share with their audience, and when someone makes a purchase using that link, the affiliate earns a commission. Affiliate programs can benefit both the company and its affiliates, as the company can increase its sales and brand exposure while affiliates can earn money by promoting products they believe in. To run a successful affiliate program, it's important to provide attractive commissions, clear guidelines, and effective marketing materials to your affiliates.
