List at least one product category. Because AliExpress allows merchants to choose the product categories to list independently, and there is no minimum requirement, merchants can choose the categories that suit them according to their business model and product advantages. At the same time, AliExpress also supports merchants to operate across categories, providing more flexibility and choices. When choosing product categories, merchants should comprehensively consider their own strengths, market demand, competition and other factors, follow the principle of customer first and quality first, satisfy customers and improve their competitiveness. At the same time, they must also abide by the rules and policies of AliExpress to ensure the security and development of their accounts.
