Moz shows duplicate content, but URL's are tagged with campaign tags

[jorisbrabants]

Crawl diagnostics shows a lot of pages with duplicate content, but when I check the details, I see that it lists the same page but the url contains a campaign tag, so it's not really another page that is serving identical content...

Is there a way to remove these pages out of the Crawl Diagnostics?

Hey Joris,

I'm afraid that we aren't able to see what parameters you are adding to GWT, since we don't use that information in any way to crawl your site. We conduct a proprietary crawl of the site and report on exactly what your source code and server respond with.

Patrick is right that adding the canonical tags to your site (or using the robots.txt file to block the campaign pages) would clear up those errors in our crawler.

Since some dynamic URL generators can cause problems for crawlers, we do try to be overly-inclusive of these issues. We want people to know about potential issues with sites, even if they're not really issues in the scheme of the site owner's specific SEO implementation plan. In sum, we'd rather leave those judgments up to you. I hope this helps explain our thinking here!

Hi there

Well the canonical tag would help Moz understand that this page isn't duplicate, that's why I mentioned that tactic.

As far as Search Console, I was just trying to help get you other angles covered.

I would try canonical tags and see how that goes over on your next report.

Hope this helps! Good luck!

Thanks,

I already added the URL parameters in GWT but it's the duplicate content that is appearing in my MOZ reports because of those tags.

No way to exclude them of MOZ? Imagine you have a page that and a lot of tagged links pointing towards that page, it's gonna list all those tagged links in the duplicate content report.

Hi there

Campaign tags don't signal unique content. It's essentially the same concept as...

http://www.example.com
http://example.com

Both are two different URLs but have the same content, thus making it duplicate content, even though it's technically the same page.

What you can do is take a look into your canonical tags and make sure those are upto date and correct. You can also look into categorizing your parameters, letting crawlers know how to handle this content. Both of these resources will help with your duplicate content issue.

Yoast has a great resource as well for common causes and solutions to duplicate content.

Hope this helps! Good luck!
