What Is a Website Like eBay?

Online marketplaces like eBay connect buyers and sellers from all over the world. These platforms act as virtual meeting points where individuals, small businesses, and even large retailers can list products for sale. Buyers browse, compare, and purchase goods—sometimes through auctions and sometimes at fixed prices.

While eBay is often credited as one of the pioneers, many similar sites offer unique features and business models. Some focus on new goods, some on collectibles, and others specialize in local or global sales.


How Do Websites Like eBay Operate?

1. Marketplace Model

Websites like eBay function as intermediaries between buyers and sellers:

  • Sellers list items for sale on the platform.
  • Buyers browse listings, communicate with sellers, and make purchases.
  • The website handles payment processing, facilitates communication, and provides a trust framework (feedback, disputes, guarantees).

2. Selling Formats

Platforms may cover:

  • General merchandise (electronics, clothing, collectibles)
  • Vintage or handmade goods
