Rel="canonical"

[cufflinksman]

HI,

I have site named www.cufflinksman.com related to Cufflinks. I have also install WordPress in sub domain blog.cufflinksman.com.

I am getting issue of duplicate content a  site and blog have same categories but content different.

Now I would like to rel="canonical" blog categories to site categories.

http://blog.cufflinksman.com/category/superhero-cufflinks-2/

Is possible and also have any problem with Google with this trick?

I wouldn't do that. rel=canonical is supposed to point between truly or near-truly duplicate pages, usually when things like URL parameters are on URLs but don't do anything to the content.  These are completely different pages, category pages on your site, vs. ones on your blog.  I would not recommend it.  Chances are Google will just ignore your rel=canonical.  It would likely not do any damage to your rankings, but who knows down the line... you never know when they'll release a Google aardvark or some other animal from the Google zoo.

Note my work firewall blocked the blog URL so I was looking at a cached version on Google.  If the pages are truly duplicate (which they didn't appear to be), go for it.

I will agree with John and in addition to that if it is possible for you to add no index to blog’s category pages it will better!

Hi John,

Thanks for your reply. I understand your point. Now guide me what I have to do with these plenty of categories and tags at  blog.cufflinksman.com . As SEOmoz showing approx 1600 duplicate content due to categories and tags at blog.

What approach you suggest me to remove these duplicate content and also improving ranking of cufflinksman.com(Our main site).

Hope you suggest excellent solution for this as I didn't like to no index these categories and tag as they have excellent content.
