What is Affiliate Marketing?
Affiliate marketing is a performance-based online business model where you earn a commission for promoting products or services offered by another company. Instead of creating your own product, you simply recommend a service and earn money whenever someone buys through your referral link.
Companies love affiliate marketing because they only pay for results—sales, leads, or clicks. Affiliates love it because they earn passive income without handling customer service, stock, shipping, or product creation.
