or each comment blogger generates a new link that is considered duplicate for the post when using webmaster tools, removing is denied because for third party involvement (blogger) eg: nogoomfm.blogspot.com/2008/04/contact-us.html? showComment=1234256220000 I now have 700 duplicate for 300 post it is disappointing plz help see arabic discussion for this issue
I believe that Blogger doesn't have an option to fix this, but if you are using Wordpress I got a solution. You go to Discussion and uncheck paginate comments, so it doesn't develop duplicate contents.
see if 'canonical url' tag helps u...its used to inform SE's that the same content from ur site is used elsewhere and not to consider it duplicate.
