2. Professionalism. Baidu search has a strong correlation, such as searching for medical keywords, and more than half of the entries are related introductions of various hospitals and drugs; On the other hand, in Zhihu, because most of the answers are completed by individuals, not large enterprises, its professionalism is questionable.
3. Be targeted. Searching for content in Baidu can get relatively single search results; However, the content searched on Zhihu usually contains lengthy principle explanation, author's understanding and application expansion, which wastes readers' time.
4. Be friendly. When asking for help from Baidu, the search results given by Baidu are very friendly, with various product recommendations and contact information of various enthusiasts; On the other hand, in Zhihu, respondents often attack questioners mercilessly, which is very unfriendly.
5. Public welfare. As the most authoritative website in China, Baidu not only provides free information consultation, but also actively recommends various applications to users and provides one-click installation service; On the other hand, in Zhihu, even the most basic copying content is not allowed, which seriously affects the exchange and sharing of information.
6. advanced nature. Baidu's visits far exceed Zhihu's, which shows that Baidu always represents the fundamental interests of the overwhelming majority of the people. That is to say, it is not Baidu who says that it is authoritative, but the person who chooses Baidu's authority.
