This list includes general marketplaces and classified sites with a significant c-to-c component. Rankings are based on total monthly visits in April 2022, sourced from SimilarWeb, with international domains aggregated to create a traffic total for one specific brand. For example, monthly visits to all OLX sites globally have been combined into a global total. Pure mobile apps are not included due to the challenges of comparing app usage to site visits. Facebook Marketplace is excluded because its traffic is not tracked externally or released by the company.
