Affiliate marketing and dropshipping are two popular online business models that allow entrepreneurs to earn income with relatively low startup costs. Affiliate marketing involves promoting products or services and earning a commission for each successful sale made through a unique referral link, while dropshipping allows you to sell products without holding inventory, as suppliers handle storage and shipping directly to customers. Both models offer flexibility, can be managed from anywhere, and provide opportunities to build scalable businesses with minimal upfront investment, making them attractive options for anyone looking to start an online business.
