The algorithmic recommendation mechanism employed by the Douyin short video platform enables the customization of individual interest databases for each user, achieving precise interest targeting. When introducing its e-commerce feature, Douyin adopted its existing short video distribution logic and utilized algorithms to create a unique "interest-based e-commerce" model. In April 2021, Douyin officially positioned itself as an interest-based e-commerce platform. The platform accurately matches product content with potential users' interests, creating a discovery-oriented consumption experience that features "products finding people." This mechanism not only triggers massive consumption demand from over 600 million daily active users but also significantly shortens the path to product conversion, facilitating efficient conversion and retention of users from awareness and interest to purchase and repurchase.
