Douyin’s jewelry category targeted investment promotion means that on the Douyin platform, merchants can choose specific jewelry categories according to their business needs, and conduct targeted investment promotion for agents with shipping capabilities. The purpose of this is to better and more accurately locate target customers and improve sales efficiency and effectiveness. Specifically, Douyin’s jewelry category targeted investment promotion allows merchants to better target their products and target user needs and choose suitable agents for commercial cooperation. If the merchant’s products are more inclined towards the female market, they can choose to cooperate with some agents with a larger female consumer group, which can better meet market demand and improve product sales efficiency. In addition, through targeted investment promotion, merchants can also establish long-term and stable cooperative relationships with agents to achieve a mutually beneficial and win-win effect.
