When Zhihu was founded, the target market was the Q&A community in the Internet industry. At present, Zhihu is positioned as a comprehensive knowledge sharing platform. At the beginning of its establishment, Zhihu was positioned as a question-and-answer community in the Internet industry. It chose the question-and-answer market segment of the Internet industry, and after word of mouth, it constantly expanded the industries and fields involved, and gradually became a comprehensive knowledge sharing platform today. Compared with the shell, the positioning of the shell is scientific. Although science has all kinds of fresh and interesting cold knowledge, its essence is difficult for the public to understand, so it is difficult to expand the number of users. Zhihu, on the other hand, focuses on Internet Q&A. Since the post-80s, post-90s and post-00s are all deep users of the Internet, the threshold of the Internet topic itself is not high, and everyone can talk about it. At the same time, due to the rapid development of the Internet industry and the sharp increase of Internet employees, it has objectively helped the growth of Zhihu.
