You can find the top 100 Chinese websites, calculated daily, at China Internet Index System (CIIS) 中国互联网指数 . Today's top 10 are: 1) Baidu.com; 2) QQ.com; 3) Sina.com.cn; 4) Netease 163.com; 5) Sohu.com; 6) cn.yahoo.com; 7) Taobao.com; 8) TOM.com; 9) Vnet.cn (who knew?); 10) Soso.com.
CIIS is a joint effort by Internet research and incubator Chinalabs.com (directed by Bokee.com CEO Fang Xingdong) and the National Bureau of Statistics. It was born in 2004 as CISI, but was revamped and relaunched this year in October as CIIS. They use their own standard, "CIIS value," to evaluate the direction of change for any particular website, but I can't find any information on what goes into creating that "CIIS value," beyond the fact that they are "monitoring web traffic." Here's the CIIS value for IT community site Donews.com, for the last two months:
CIIS also calculates the Google page rank, Google search results, and Baidu search results, all on the same page so you can compare them. Get this: Donews.com has around 1.1 million results on Google, and more than 8.3 million search results on Baidu.
Finally, another useful feature is the piechart that tells you how the traffic is divided on the site's sublevel domains, so that we can see that QQ is getting the most traffic on its Qzone, entertainment, and news domains. You could track the growth of new domains with the CIIS.
