Baidu is a platform you can’t skip when conducting SEO in China. Not only because it’s the dominant player in the market but also due to the fact that it has a more sophisticated search algorithm and extensive database than other search engines in the market.
As you likely already know, China’s search engine market isn’t dominated by Google like the in the rest of the world.
