An e-commerce marketplace is a platform where different sellers can offer their products or services online and customers can buy them. Such platforms bring buyers and sellers together, offering a wide range of products and often providing an easy shopping experience. Major online marketplaces such as Trendyol, Hepsiburada, Amazon, eBay and Alibaba are the most well-known examples.

E-commerce marketplaces typically provide the tools for sellers to list their products, set prices and communicate directly with potential buyers. For buyers, they offer benefits such as the ability to compare products and prices from various sellers, access to user reviews and secure payment options. These platforms usually generate revenue by charging a commission on the sale.
