The difference between bilibili and Tik Tok lies in the content positioning, audience characteristics, business model, recommendation mechanism, definition and users.

1. Content orientation: bilibili focuses on the secondary culture and ACG culture, which includes games, animation, music, dance, science and technology, with more emphasis on the in-depth development of specific fields. Tik Tok, on the other hand, focuses on life, including food, travel, music, emotion and other aspects, and its content is more comprehensive.

2. Audience characteristics: The main user groups in bilibili are teenagers and young people, with a large proportion of male users, mostly anime fans, gamers and second-generation enthusiasts. Tik Tok has a relatively wide user base, covering people of all ages and professional backgrounds.

3. Business model: bilibili's business model includes advertisements, paid members and games, while Tik Tok's main income sources are e-commerce and advertisements.

4. Recommendation mechanism: Tik Tok adopts a recommendation-based traffic distribution mechanism, and recommends videos that users may be interested in through algorithms, which helps to ensure the user experience and increase the user's stay time on the platform. Bilibili's recommendation mechanism relies more on manual review and content matching than on algorithms.

5. Definition and users: Tik Tok is defined as a music short video community, while bilibili is defined as a cultural community. This difference in definition determines that the objects used by the two are different.
