The primary function of a digital marketplace is to connect buyers and sellers through a virtual platform, facilitating the exchange of goods and services. These marketplaces leverage technology to streamline transactions, allowing users to compare products, read reviews, and make purchases conveniently. By providing a centralized location for various sellers, digital marketplaces help expand market reach and enhance competition. Examples include platforms like Amazon, eBay, and Etsy, each catering to different niches and customer needs.
