A marketplace is a platform where buyers and sellers come together to exchange goods and services. This can happen in physical locations, like a farmers' market, or online, like Amazon or eBay. Marketplaces provide a space for various products, allowing consumers to compare prices and find what they need easily. In addition to traditional goods, some marketplaces focus on services, such as Uber for rides or Airbnb for lodging. These platforms often facilitate transactions by providing tools for communication, payment, and reviews, making it easier for users to trust each other and complete their exchanges safely.
