Baidu is the most popular search engine in China. It is estimated, Baidu currently has a 65% share of the search engine market in China. The other two major search engines in the market are Haosou formally known as 360 and Sogou.
For any organisation wishing to target the Chinese market, optimising for Baidu is a necessity. While it’s important to keep Haosou and Sogou in mind as well, both are relatively new search engines that have only recently emerged in the Chinese market.
