Baidu, in China, is the mother of all search engines. Despite plucky newcomer rivals like Sogou, Baidu still commands a 70-80% share of the online search market. As of 2021, it is the 7th most visited website in the entire world, despite around 90% of its visitors being from only one country. This should give an idea of not only the scale, but also the importance of Baidu for any brands looking to do business in China.
