Google's Doubleclick recently released the top 1000 unique visitors to the world's websites in April (excluding Google's own websites and adult websites). Seven of the top 20 on Google's list are from China, with shopping site Taobao, video site Youku and search site SOSO, owned by Tencent, in addition to the three portals NetEase, Sina and Tencent and Baidu. Although Facebook ranked first in the world, China's SNS websites did not perform well, with only Renren entering the top 100.
