eBay operates as an online marketplace where individuals and businesses can buy and sell a wide variety of products, including electronics, fashion, and collectibles. The platform allows users to list items for sale, either through auction-style listings where buyers can place bids or through a 'Buy It Now' option for immediate purchases. eBay stands out from its competitors by offering a vast selection of products, a user-friendly interface, and strong protections for both buyers and sellers. The company generates revenue primarily through transaction fees charged to sellers, as well as advertising fees and subscription services for premium features. eBay's goal is to connect millions of buyers and sellers globally, making it easier for them to transact online.
