Duplicate without user-selected canonical excluded
-
We have pdf files uploaded in the media of wordpress and used in our website. As these pdfs are duplicate content of the original publishers, we have marked links to these pdf urls as nofollow. These pages are also disallowed in robots.txt
Now, Google Search Console has shown these pages Excluded as "Duplicate without user-selected canonical"
As it comes out we cannot use canonical tag with pdf pages so as to point to the original pdf source
If we embed a pdf viewer in our website and fetch the pdfs by passing the urls of the original publisher, would the pdfs be still read as text by google and again create duplicate content issue? Another thing, when the pdf expires and is removed, it would lead to 404 error.
If we direct our users to the third party website, then it would add up to our bounce rate.
What should be the appropriate way to handle duplicate pdfs?
Thanks

From what I have read, so much of the web is duplicate content so it really doesn't matter if the pdf is on other sites; let google figure it out. (example, every car brand dealer has a pdf of the same car model brochure on their dealer site) No big deal. Visitors will be landing on your site from other search relevance - the duplicate pdf doesn't matter. Just my take. Adrian

Sorry, I mean pdf files only

As the pdf pages are marked as a duplicate and not the pdf files, then you should check which page has duplicate content compared to it, and take the needed measures (canonical tags or 301 redirect) form the page with less rank to the page with more rank. Alternatively, you can edit the content so that it isn't anymore duplicate.
If I had a link to the site and duplicate pages, I would be able to give you a more detailed response.

Hello Daniel
The pdfs are duplicates from another site.
The thing is that we have already disallowed the pdfs in the robots.txt file.
Now, what happened is this - We have a set of pages (let's call them content pages) which we had disallowed in the robots file as they had thin content. Those pages have links to their respective third party pdfs, which have been marked as nofollow. The pdfs are also disallowed in the robots file.
Few days back, we improved our content pages and removed them from robots file so that they can be indexed. Pdfs are still disallowed. Despite being disallowed, we have come across this issue with the pdf pages as "Duplicate without user-selected canonical."
I hope I make myself clear. Any insights now please.

If the pdfs are duplicate within your own site, then the best solution would be for you to link to the same document from different sources. Then you can delete the duplicated documents and 301 redirect them to the original.
If the pdfs are duplicate from another site, then disallowing them on robots.txt will stop them from being marked as a duplicate, as the crawler will not be able to access them at all. It will just take some time for them to be updated on google search console.
If however, you want to add canonical tags to the pdf documents (or other non-HTML documents), you can add it to the HTTP header through the .htaccess file. You can find a tutorial on how to do that in this article.

Canonical and Alternate Advice
At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?

Rel=canonical and internal links
Hi Mozzers, I was musing about rel=canonical this morning and it occurred to me that I didnt have a good answer to the following question: How does applying a rel=canonical on page A referencing page B as the canonical version affect the treatment of the links on page A? I am thinking of whether those links would get counted twice, or in the case of ver-near-duplicates which may have an extra sentence which includes an extra link, whther that extra link would count towards the internal link graph or not. I suspect that google would basically ignore all the content on page A and only look to page B taking into account only page Bs links. Any thoughts? Thanks!

Duplicate URLs ending with #!
Hi guys, Does anyone know why a site can contain duplicate URLs ending with hastag & exclamation mark e.g. https://site.com.au/#! We are finding a lot of these URLs (as duplicates) and i was wondering what they are from developer standpoint? And do you think it's worth the time and effort adding a rel canonical tag or 301 to these URLs eventhough they're not getting indexed by Google? Cheers, Chris

Partial duplicate content and canonical tags
Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.

Lowercase VS. Uppercase Canonical tags?
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight. Thanks!

How to Remove Joomla Canonical and Duplicate Page Content
I've attempted to follow advice from the Q&A section. Currently on the site www.cherrycreekspine.com, I've edited the .htaccess file to help with 301s - all pages redirect to www.cherrycreekspine.com. Secondly, I'd added the canonical statement in the header of the web pages. I have cut the Duplicate Page Content in half ... now I have a remaining 40 pages to fix up. This is my practice site to try and understand what SEOmoz can do for me. I've looked at some of your videos on Youtube ... I feel like I'm scrambling around to the Q&A and the internet to understand this product. I'm reading the beginners guide.... any other resources would be helpful.
