正當大部份的website 都已經利用了google analytics 這個強大的分析功能，而最重要的是完全免費的。
Yahoo 就推出一個web analytics，功能上其實差不多，不過charting 方面，yahoo 的玩法是可以自己drag and drop 去define 自己想要的reporting
custom reporting 應該是最大的賣點呢~
Chowky 覺得好奇怪，為何會有age group, gender 的資料? 太奇怪了。
Visitor Demographics Reports – NEW FEATURE
Better understand who your customers are and how to better align your marketing with your desired audience.
The Demographic reports and dashboard provide an aggregated snapshot of the age groups, gender, and age-gender cross-tabulations of customers from each of your traffic channels. These dashboards help you picture your visitors as people rather than just a series of clicks.
Age and gender can also be used as dimensions for filtering and segmenting data. For instance, it may be interesting to see what age and gender your campaigns are reaching, how audiences differ from channel to channel, and who your audience is for each of your products.
Demographic information can be used to create more targeted campaigns, or to find high performing audiences in new channels.
當然如果flash 方面的integration 未做好的話，chowky 都是會stick with google analytics 先。
