Search Monitor: China

Search engines are increasingly censoring their results, often by geographic location, having a significant, negative impact on the right to freedom of expression. The most advanced cases of censoring political content is in search engines that market a version of their product in China. This project aims to expose and monitor the censoring practices of search engines with a specific focus on China.

In order to avoid interference from the China's filtering system, the China-specific versions of Google and MSN, which are hosted outside of China, are queried from outside of China and the China-specific versions of Yahoo and Baidu, hosted inside China, are queried from inside China.
