Is canonical link enough?

[nuxeo]

Hi SEOmozers!

I have a question.

SEOmoz analysis report me some duplicate that I thought I had fix.

I can give a concrete example.

This page:

http://www.nuxeo.com/en/about/events/dec2011training-boston/moreinfo

is reported as having 6 duplicated URL in the tool. When I click on 6, SEOMOZ tells me "Our crawl bots are getting their joints greased to fetch you even better data. Sorry for the delay!"

And on the page itself, I placed a canonical link to follow recommandation.

rel="canonical" href="http://www.nuxeo.com/en/about/events/apr2012training-boston" />

As a result I am curious why I would have this reported as duplicate by SEOmoz.

Is this a bug?

Thanks for feedback!

You are producing duplicate content on the monthly pages e.g.

http://www.nuxeo.com/en/about/events/apr2012training-boston

http://www.nuxeo.com/en/about/events/jan2012training-boston

Cut and paste a chunk of the page text into the Google search box, you will then see all the duplicates being indexed by Google.

Greetings Champions!

I could be blind or weary from slaying dragons but it appears the your Canonical link is not even in place to resolve this burden placed upon you good sir.

Here is an Example of what the source with a canonical link looks like.

Good luck on your quest for Page 1!

It's not in http://www.nuxeo.com/en/about/events/dec2011training-boston/moreinfo but in http://www.nuxeo.com/en/about/events/dec2011training-boston

Unfortunately, it looks like we haven't completed the full crawl on your site yet, although I'll ask the team.

I am seeing another page rank in Google for the Title:

"Nuxeo Document Management December 2011 Training"

It's this one:

http://www.nuxeo.com/en/layout/set/print/about/events/dec2011training-boston

I have a feeling that, with all of the forms and date variations, you're creating near-duplicates that are low-value. These aren't 100% duplicated, but it's enough that Google is filtering out the main page.

Looks like we had a minor bug and it got fixed last night - you should be able to see the duplicates now. I checked out a couple, and we're crawling a few tracking parameters in URLs, such as:

utm_source=enews&utm_medium=email&utm_campaign=enews20120117

Looks like these might be links in an e-mail newsletter? The good news is that Google is pretty good about ignoring these, and it looks like your canonical tag is properly configured. I think we may be reporting these too aggressively. As far as I can tell, you should be ok.
