Canonical doesn’t work for Baidu, Try rel=”index”
Update on March 2, 2013: Baidu now supports the canonical tag.
Google has introduced the canonical attribute to SEOs and webmasters for a while. And the attribute is very useful as an alternative way to 301 redirection.
But for Baidu, the canonical attribute is still unrecognized.
