Duplicate Content from Google URL Builder

[joshuaopinion]

Hello to the SEOmoz community!

I am new to SEOmoz, SEO implementation, and the community and recently set up a campaign on one of the sites I managed. I was surprised at the amount of duplicate content that showed up as errors and when I took a look in deeper, the majority of errors were caused by pages on the root domain I put through Google Analytics URL Builder.

After this, I went into webmaster tools and changed the parameter handling to ignore all of the tags the URL Builder adds to the end of the domain. SEOmoz recently recrawled my site and the errors being caused by the URL Builder are still being shown as duplicates.

Any suggestions on what to do?

I've seen exactly the same thing and have assumed that this is down to the SEOMoz crawler not being able to pick up the settings in Webmaster Tools.

Have you noticed an improvement in your Webmaster tools reports?

I don't know if there is anything you can do at this stage, regardless of whether you're looking at SEOMoz or WMT. I wouldn't be too concerned about it if you have correctly set parameter handling and backed that up with some canonical tags if appropriate.

Very often, these alerts are meant to flag something for you to check with a human eye, but this and all of the above is my interpretation of what you are describing from my own experience so I guess you need to wait for A Mozzer to reply about the intricacies of what their crawler is telling you.
