Google趋势—Google Trends
星期四, 06月 22nd, 2006还记得百度出过一个百度指数么？百度指数，实际上就是让你追踪某一个或几个关键词的受关注程度，根据该关键词前一天的被搜索的次数来进行排序。
现在Google也出了这么一个服务，名为：Google趋势(Google Trends)，这个名字比什么指数更直观，呵:)
Google Trends builds on the idea behind the Google Zeitgeist, allowing you to sort through several years of Google search queries from around the world to get a general idea of everything from user preferences on ice-cream flavors to the relative popularity of politicians in their respective cities or countries.
