A commission in affiliate marketing is the money you earn when you promote someone else's product or service and it leads to a sale or action. Think of it like a reward for helping a company make a sale. When you share a special link provided by the company and someone buys through that link, you get a percentage of the sale or a fixed amount. The amount depends on the agreement with the company. Some programs pay a small percentage, while others offer more, especially for high-value items. It's a way to earn income by recommending things you believe in, without creating the product yourself. Make sure to choose programs that match your audience's interests for better results. What are your thoughts on how commissions work in affiliate marketing?
