Duplicate page content showing up with proper use of canonical tag

[Leighm]

Hi,

In the Crawl diagnostics reports, I'm getting lots of duplicate errors warnings e.g. duplicate page title. In most cases these are tracking urls and the page has a canonical tag pointing to the original page.

It would be helpful if the crawl analysis reports could separate these out from ones that are of genuine concern.

It can also happen when there's a noindex tag on a page.

Thanks,

Leigh

Can you please list the domain?

Hi,

I'm not sure I want to list the domain here, but here's a example of what I mean. We create google tracking links (google url builder) for use in a newsletter. The homepage looks like this:

http://www.site.com/

and one the links in the newsletter might look like this:

http://www.site.com/?utm_source=newsletter&utm_medium=email&utm_content=offer&utm_campaign=1

When you look at the source code for both urls, they both have the canonical tag equal to:

http://www.site.com/

So, Google knows there's no duplicate content issue there. It would be good if the diagnostics tool could recognise that too.

Thanks,

Leigh

Let me ask you this: Does your site exist for both the www and non www? Example: http://www.site.com/   http://site.com/

Yes, but the non-www version 301 redirects to the www version.

Hi Leigh,

The SEOmoz PRO platform is designed to detect canonicals, and disregard these kind of errors when proper canoncials are in place.

That said, there have been bugs before which has presented this from working correctly, but most of those have been fixed. If you are still seeing problems, I encourage you to contact the help team (help@seomoz.org) to make sure everything is working okay in your campaign, and to verify this is actually a bug and not something wrong with your canonical tags.

Best of luck!

Hi Cyrus,

I don't see any issues with the canonical tag.

I'll contact the help team.

Thanks,
