Canonicalization isn't consistent across site!?!

[SEOProPhoto]

I started managing a fairly small site that consists of a home page, flash portfolio, and a wordpress blog.

The home page ( main index ) is canonicalized as:  The wordpress blog is canonicalized as

Does canonicalization need to be consistent across the site?

Could the difference in canonicalization cause any ranking problems, and or indexing problems for the blog / entire site?

Any thoughts are appreciated!

Thanks Barry,

I sorta thought that would be the case, but wasn't a 100% sure

Oh, you should definitely either always have www or not have www on both your site and the canonical tags.

I would imagine it'd cause a problem if you're saying http//domain.com is canonical but it then redirects to http://www.domain.com as you're sending mixed messages.

I would definitely sort it out so it used the right version of the URL.

Hi Barry, thanks for you response.

Sorry, the "/blog" was left off the inital post.

The canonical urls for each as are such,

Home page Blog page

Is it "OK" that the home page and blog use different prefix's?

Are you telling me domain.com/blog (or wherever WP is) has the canonicalization tag of just domain.com?

That is bad! Read this - http://www.seomoz.org/blog/catastrophic-canonicalization

The canonicalization tag should be the canonical version of the page and used to eliminate duplicate version of a page (such as those with tracking parameters).

Have a read of this - http://googlewebmastercentral.blogspot.com/2009/02/specify-your-canonical.html - and let me know if you have specific questions
