Duplicate Page Titles & Content
-
We have just launched a new version of a website and after running it through SEOMOZ we have over 6000 duplicate title & content errors. (awesome)
We have products that show up multiple times under different URLs however we "thought" we had implemented the rel=canonical correctly.
My question is - do these errors still show up in SEOMOZ despite the canonical tags being there OR if they were "correct" would we be getting "zero" errors?

Hi Ladies & Gents
It was a canonical tag error - we went from 6000 errors to 11500 errors and now after the issue was fixed we have a handful of non related errors to sort.
Really appreciate all the feedback.
Kind Regards
Liam

how are you getting on, did this get resolved?

Hey Peter, I'm just having problems with the 4th example, and I believe you are doing it wrong. Not to try to point out problems with your software, but the report that I now have is more or less unusable for my clients because you see the duplicates this way.
What we have, is duplicates reaching to different categories with canonical set up.
B references A in category 1
D references C in category 2
and hundreds more ...But, because B and D are empty, except for the navigation, the tool sees B and D as duplicates. Two problems with that:
1. They are not even "considered" by Google, because they reference something else as a canonical, so they are not duplicates of each other.
2. The report now shows 10 different pages from different categories as duplicates, and with the number of false identified duplicates it is now impossible for me to find any real duplicates.So, is my understanding wrong, and what can we do to find the really duplicated pages?
Thanks,

Hi there,
Thanks for reaching out to us! I'm sorry if there are any confusions regarding the way we classify duplicate content. Just clarify a few things, here is how our system interprets duplicate content vs. rel canonical:
Assuming A, B, C, and D are all duplicates,
If A references B as the canonical, then they are not considered duplicates
If A and B both reference C as canonical, A and B are not considered duplicates of each other
If A references C as a canonical, A and B are considered duplicated
If A references C as canonical, B references D, then A and B are considered duplicates
The examples you've provided actually fall into the fourth example I've listed above.For more information on using canonical tags, check out this great post by our very own Dr. Pete:

Best,
Peter

Thanks for the responses - sort of what I feared but haven't implemented canonical tags before so was unsure whether they should be showing.
Looks like there is a long day ahead

I am afraid i don’t know the detailed ins and outs of SEOMozs products, however we have some paginated pages on one of our sites. Our crawl reports are not showing errors for duplicate page titles and they are detailed in the notices section as canonical.
This implies to me that the crawl reports do ignore correctly formatted canonical tags. Perhaps you could download the error list and the list of discovered canonical tags and compare the two to confirm. Alternately try crawling the site with other tools, the one i would recommend is Screaming Frog as this will allow you to filter canonical tags in the reports, and do it for free.

Hi,
All things being equal, if the canonical tags are properly implemented you should see zero.
For ecomm sites, it is pretty easy to get duplicate title and content warnings from similar but not identical product pages which is usually an indication of thin content (no descriptions or one line descriptions that are almost identical).
So first line of enquiry is to confirm the canonicals are really doing what you expect them to be doing and if after the next crawl you still see duplicate issues then download them in a csv and start investigating them to see which pages are being flagged.
Hope that helps!

I have an issue with hubspot's blog platform and duplicate content.
It is redirecting all https to http and I am unable to change it, resulting in a lot of duplicate content. Has anyone else experienced this? If so, did you find a solution? Or does anyone have any suggestions?

Duplicate content in crawl despite canonical
Hi! I've had a bunch of duplicate content issues come up in a crawl, but a lot of them seem to have canonical tags implemented correctly. For example: http://www.alwayshobbies.com/brands/aztec-imports/-catg=Fireplaces http://www.alwayshobbies.com/brands/aztec-imports/-catg=Nursery http://www.alwayshobbies.com/brands/aztec-imports/-catg=Turntables http://www.alwayshobbies.com/brands/aztec-imports/-catg=Turntables?page=0 Aztec http://www.alwayshobbies.com/brands/aztec-imports/-catg=Turntables?page=1 Any ideas on what's happening here?

URL paramters and duplicate content
Hello, I have a 2-fold question: Crawl Diagnostics is picking up a lot of Duplicate Page Title errors, and as far as I can tell, all of them are cause by URL parameters trailing the URL. We use a Magento store, and all filtering attributes, categories, product pages etc are tagged on as URL parameters. example: Main URL:
Moz Pro | | yacpro13
/accessories.html Duplicated Title Page URLs: /accessories.html?dir=asc&order=position
/accessories.html?mode=list
/accessories.html?mode=grid
...and many others How can I make the Crawl Diagnostics not identify these as errors? Now from an SEO point of view, all these URL parameters are been picked up by google, and are listed in WedMaster Tools -> URL parameters. All URL parameters are set to "let google decide". I remember having read that Google was smart enough here to make the right decision, and we shouldn't have to worry about it. Is this true, or is there a larger issue at hand here? Thankas!0 -

Duplicate Content Issues with WordPress
I'm having some difficulty with a few of the sites I'm managing right now. When I run a report here, I'm getting a duplicate content issue with sites that I'm running through WordPress. Sites running on a different CMS are not getting the issue. The duplicate content is being listed as from two URL's that are identical. I checked trailing slash, spelling, capitalization, everything. It looks like the same site is being marked as two with duplicate content. Does anyone have any ideas of what could be causing this and/or what I may be able to do to resolve the issue (or if it's really something to worry about or not)? Thanks. (and thanks for helping the new guy!)
