Posted On Friday, June 26, 2009 at at 5:44 AM by Abdelrahman EllithyBlogger makes a link for every comment on your blog that is for a post like :
http://nogoomfm.blogspot.com/2009/05/blog-post_19.html
may get urls as :
http://nogoomfm.blogspot.com/2009/05/blog-post_19.html?showComment=1242753180000
this is a major problem for famous massively commented posts and blogs,
Here is the way you can solve it using the rel="canonical" attribute
1- Log in to your blogger Dashboard.
2- Choose Layout ( edit HTML template) and Download the template as backup.
3- Find :
</head>
4- Put before it the following code :
<!-- 100fm6.com block duplicate content START -->
<b:if cond='data:blog.pageType == "item"'>
<link expr:href='data:blog.url' rel='canonical'/>
</b:if>
<!-- 100fm6.com block duplicate content END -->
5- Save your template.
Google uses re='canonical' hack in it blog too.
