Baidu has decided to ban all paid advertisements from binary options brokers across its network. This comes as part of a move from the search engine company to remove advertisements from its search results from industries and businesses that it deems 'risky'. As Baidu accounts for 70% of all searches in China, this could come as a huge change to financial companies trying to attract clients from the country. The change comes as an indirect response to demands placed on Baidu by the Chinese internet regulator after the death of a student, who received a controversial treatment he found through a Baidu paid search ad. Following the regulators' demands to reduce the number of paid adverts and check adverts credibility more thoroughly, this move from Baidu goes beyond the new rules placed upon them.
