China's search engine market continues to heat up, with the number of Internet users rocketing to 618 million by the end of last year.

Leading search engine, Baidu, accounted for 81.4 percent of market share while Google suffered a decline accounting for only 12.3 percent in the third quarter of 2013, according to data from Internet analyst iResearch Consulting Group.

Qihoo 360's search engine, launched in 2012, showed its growth potential as market share inched up to 1.6 percent.

A rapid increase in mobile search engine users is also expected to prompt a surge in the market, according to industry analysts.
