Opinion | Online search: Qihoo, Sogou continue to grow
New data show that Sogou and Qihoo continue to make gains on search leader Baidu, with Qihoo potentially set to make a serious challenge against Baidu's years of dominance.

By comparison, Baidu's search revenue was on track to approach the US$1 billion mark in the third quarter, meaning Sogou is about 4 per cent of Baidu's size in revenue terms. That's an interesting comparison, since these October market data figures would indicate that Sohu is about 10 per cent of Baidu's size in terms of market share. Part of the difference obviously lies in the fact that Baidu, as the industry leader, can charge higher prices for its advertising. Still, Sogou's position may be overstated in this latest data, and perhaps its true market share is probably around 5-6 per cent.
There's less new to say about Qihoo, since the company has yet to report its latest quarterly results. But Qihoo has been making non-stop headlines these last three months on the rapid rise of its search engine, which includes some innovative functions such as allowing users to conduct integrated searches of multiple engines and also allowing them to rate their search results.
Qihoo's shares have rallied sharply on all the hype, and are now up around 50 per cent since the end of July. I admit that I like Qihoo's story, since it's nice to see someone finally challenge Baidu's years of dominance in search. I won't say Qihoo's stock is overpriced just yet, but it will have to show continued growth in the search business -- both in market share and revenue -- if it wants to keep its exciting new story alive. If it succeeds, the company could perhaps see some of the explosive growth that Baidu saw in its early days that helped to make it China's second most valuable Internet company.
