Douyin and Taobao have a data sharing partnership. Douyin can access Taobao's open platform API to read Taobao users' behavior data, including browsing, searching, purchasing and other information, so as to provide Douyin's recommendation algorithm with more accurate user portraits and interest tags, and recommend products and content that better suits users' interests.

At the same time, Douyin can also use Taobao's advertising platform to deliver advertisements to Taobao users, achieving more accurate advertising delivery.
