Google last week signed a deal with Chinese portal Sina.com, giving the US search engine a boost in its race to catch up with rival Baidu.com.
Under the terms of the agreement, Google will provide Web page search service for Sina.com. In return, Google will share the advertising revenue generated by traffic from China's most-visited portal.
Sina's own search engine, iAsk, which was earlier used to provide Web page services, will now serve only for vertical search, or specialized search, including news, photo, blogs and mobile search, said Charles Chao, CEO of SINA Corp.
The two companies also said they will expand their cooperation into news and other content areas.
