In this video, Motley Fool techanalyst Andrew Tonner takes a close look at China's search engine giant Baidu (NASDAQ:BIDU), and gives you three reasons why now is the time to buy. Because the search business generates such high margins in general due to such effective advertising targeting, it's already a great space to be invested in. But when you combine that with an eye to how low Internet penetration and Internet advertising both still are in China and how rapidly they are both expanding, and how well positioned Baidu is to take advantage of that as the overwhelmingly dominant market share holder in China, you get a stock that can only be a strong buy.
