An online marketplace is a type of e-commerce platform that allows buyers and sellers to transact with each other. Two of the most popular online marketplaces are eBay and Etsy. eBay is an online auction and shopping website in which people and businesses buy and sell a wide variety of goods and services worldwide. Etsy is an e-commerce website focused on handmade or vintage items and supplies, as well as unique factory-manufactured items. Both eBay and Etsy provide a platform for buyers and sellers to connect and conduct business.
