how to sell something on marketplace can refer to general online marketplaces like Amazon, eBay, Etsy, or Facebook Marketplace. Each platform has its own rules and audiences, but the basic process is the same: set up an account, create listings, provide compelling visuals and descriptions, and choose a fulfillment method. Amazon and eBay favor structured listings and ratings, while Facebook is more casual and location-based. Regardless of platform, pricing competitively, responding to customer inquiries quickly, and offering a reliable return policy all contribute to higher sales and better seller ratings.
