Duplicate without user-selected canonical excluded

[dailynaukri]

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.
