The three main types of eCommerce websites are B2C (Business-to-Consumer), B2B (Business-to-Business), and C2C (Consumer-to-Consumer).
B2C websites are the most common type, where businesses sell products or services directly to consumers. Examples include Amazon and Walmart.
B2B websites involve transactions between businesses, such as manufacturers, wholesalers, and retailers. An example is Alibaba, where businesses can source products from manufacturers.
C2C websites facilitate transactions between consumers. They're essentially online marketplaces where individuals can buy and sell items. eBay is a prime example of a C2C website.
