Why do pages with canonical urls show in my report as a "Duplicate Page Title"?

[DPSSeomonkey]

eg:

Page One
<title>Page one</title>
No canonical url

Page Two
<title>Page one</title>

Page two is counted as being a page with a duplicate page title.
Shouldn't it be excluded?

You should include the rel canonical on both pages. Eg:

Page One
<title>Page one</title>

Page Two
<title>Page one</title>

Hope that helps,

I'd love a few more opinions on this. So far everything I've read has said only to place the canonical on the pointing page.

That should work - it's possible your implementation isn't 100% correct (can't tell from the example), but it's possible that we're not handling this completely right. I'm going to ping the product team and see what they can tell us.

Thanks Peter, Google follows my implementation correctly so I'm pretty sure it's something overlooked in SEOMoz Pro

Thanks for the question!

I did a little digging, and you are correct in that a duplicate title should not be shown here. There are some cases where a URL is canonicalized to another, but our crawler still report it as a duplicate title.

The good news is that we have an update in the works that will exclude canonicalized duplicates correctly. We are testing it now and hope to have it in place by late January.

This update will also fix a lot of other small bugs and be more robust overall. I hope this helps for now. We'll be sure to announce when the update goes out.

Thanks Adam, that would be very awesome of you and your team!
