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.

Near Duplicate Title Tag Checker
Hi Everyone, I know there are a lot of tools like Siteliner, which can check the uniqueness of body copy, but are there any that can restrict the check to the title tags alone? Alternatively, is there an Excel or Google Sheets function that would allow me to do the same thing? Thanks, Andy

Spammy page with canonical reference to my website
A potentially spammy website http://www.rofof.com/ has included a rel canonical tag pointing to my website. They've included the tag on thousands of pages on their website. Furthermore http://www.rofof.com/ appears to have backlinks from thousands of other low-value domains For example www.kazamiza.com/vb/kazamiza242122/, along with thousands of other pages on thousands of other domains all link to pages on rofof.com, and the pages they link to on rofof.com are all canonicalized to a page on my site. If Google does respect the canonical tag on rofof.com and treats it as part of my website then the thousands of spammy links that point to rofof.com could be considered as pointing to my website. I'm trying to contact the owner of www.rofof.com hoping to have the canonical tag removed from their website. In the meantime, I've disavowed the www.rofof.com, the site that has canonical tag. Will that have any effect though? Will disavow eliminate the effect of a rel canonical tag on the disavowed domain or does it only affect links on the disavowed website? If it only affects links then should I attempt to disavow all the pages that link to rofof.com? Thanks for reading. I really appreciate any insight you folks can offer.

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

[E-commerce] Duplicate content due to color variations (canonical/indexing)
Hello, We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content. What we have done so far: Choosing the best-selling color variation (our "master product") Adding a rel="canonical" to every variation (with our "master product" as the canonical URL) In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do? Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change) Thank you in advance

International SEO - cannibalisation and duplicate content
Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian

Does rel=canonical fix duplicate page titles?
I implemented rel=canonical on our pages which helped a lot, but my latest Moz crawl is still showing lots of duplicate page titles (2,000+). There are other ways to get to this page (depending on what feature you clicked, it will have a different URL) but will have the same page title. Does having rel=canonical in place fix the duplicate page title problem, or do I need to change something else? I was under the impression that the canonical tag would address this by telling the crawler which URL was the URL and the crawler would only use that one for the page title.
