Start with accuracy: use a clear title, useful description, correct category, relevant attributes, current price and stock, and good-quality images of the actual product.

Complete technical details that matter to the product rather than relying on a vague description. Relevant attributes make the listing easier to find and compare in Marketplace search.

Review delivery availability as well. A good listing should tell the customer what the product is and give them enough information to decide whether it suits their needs.
