Closed-loop marketing needs to build a closed loop in product research and development, brand communication, channel construction and after-sales service, extend the marketing process to the whole product life cycle, and continue to give marketing in the process of consumers consuming products, thus greatly improving consumers' recognition and loyalty to products. That is to say, in the interaction and communication with users, we should deeply grasp the habits and needs of users, follow the social rules of the Internet, and use Internet technology to innovate and transform the industrial operation rules of products in this industry with the ultimate experience attitude, so as to quickly form the spontaneous word-of-mouth communication of users and realize the subversive business model reform recognized by Internet users.

In the past, marketing was only a sales link. After the product is sold, it will be carried out by the subsequent service department or service agent. In the process of use, consumers' recognition of product brands gradually weakens, and their loyalty will gradually decrease with the passage of time. Closed-loop marketing is to maintain consumers' high recognition and loyalty to products. It is a marketing ecosystem and a combined marketing strategy with customers as the center. As the name implies, closed-loop is circle, and closed-loop marketing is also called circle marketing, which forms a high degree of word-of-mouth satisfaction rate of consumers for this product, thus fundamentally improving the depth and breadth of products among consumers. Only when the product itself has a deeper and wider impact on consumers will the product have vitality. Closed-loop marketing is to market customers in the whole product life cycle, thus greatly improving the possibility of customers choosing products again, thus forming a closed-loop marketing chain, gradually improving customer satisfaction through each cycle, and forming customers' trust in products.
