What is Baidu?

Baidu is currently the most widely used search engine in China.

Founded in Beijing by Robert Li and Eric Xu in the year 2000, Baidu had the largest market share in China in 2020, at over 70%.

Google, on the other hand, has withdrawn from the Chinese market, because China blocks most Google services through strict censorship. With a market share of under 1 %, Google plays a vanishingly small role (this market share comes from search queries from Hong Kong which are, as of Marh 2021, still working).

Baidu has its own crawlers – the Baidu spiders. These spiders can be blocked via the robot.txt file. The following user agents can be used for this purpose:
