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?

How to add Canonical Tags on Opencart Products
Does anyone know how to add canonical tags to product pages in Opencart? Is this possible to do in htaccess? If so, how specifically should it be written in? Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

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

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
