You can list your own products. Because Doudian is an e-commerce platform, merchants can freely upload and sell products in the store after registration. Merchants need to abide by the platform rules and pass the review before listing products, but as long as the products meet the regulations, merchants can list their own products. Merchants need to pay attention to various factors such as product quality, price, and pictures when listing products. At the same time, in order to increase product exposure and sales, merchants also need to use various marketing methods to attract user attention and purchases. In addition, merchants also need to deal with after-sales problems in a timely manner and ensure service quality in order to obtain good reviews and a good reputation and promote store development.
