Affiliate marketing is a performance-based marketing strategy in which a business rewards affiliates for each customer or sale brought in through their own marketing efforts. This type of marketing allows individuals or companies to earn a commission by promoting products or services of a particular brand or company. It is a win-win situation for both the business and the affiliate, as the business gains exposure and sales while the affiliate earns a passive income. With the rise of e-commerce and social media, affiliate marketing has become a popular and effective way for businesses to reach a wider audience and for individuals to monetize their online presence.
