Exact Syntax for Canonical to PDFs for Windows Server
-
Hi There,
I have got in my web several PDFs with the same content of the HTML version. Thus I need to set up a canonical for each of them in order to avoid duplicate content.
In particular, I need to know how to write the exact syntax for the windows server (web.config) in order to implement the canonical to PDF. I surfed the web but it seems I cannot find this piece of info anywhere
Thanks a lot!!

Thanks Paul
I had a look at the page, but as I can see it uses headers to identify the response, but the actions are rewrite or redirect. There is a custom response you can use,
for a definitive answer I would ask on iis.net http://forums.iis.net/
Or you could place each pdf in its own folder and place the header on the folder

To implement a canonical tag for an individual page/file in IIS, you need to insert a custom response header via an outbound rule in the IIS Rewrite module, not through the web.config.
Sorry I don't have a specific example handy (haven't had to wrassle with IIS in some time). I'll see if I can dig one up.
Meanwhile, here's a link to the relevant section of the general Rewrite Module info in case maybe Alan can suggest the specifics.

Thanks for finding that, I see it says url, but I cant see how that is actually done. All it does it create a web.config in the folder you choose, I found no way of doing it ofr the indervidual file, unless you have only one file per forder
here is the web.config, how to test it works?
<configuration><system.webserver><httpprotocol><customheaders><add name="CononicalUrl" value="Link: http:/domain.com/my.pdf; rel=canonical"></add></customheaders></httpprotocol></system.webserver></configuration>

Not according to this doc:
http://technet.microsoft.com/en-us/library/cc753812(v=ws.10).aspx
"Levels
The procedures for configuring HTTP headers can be performed at the following levels in IIS:
-
Web Server
-
Site
-
Application
-
Physical and virtual directories
-
File (URL)"
-
-
My mistake
-
I don't think this can be done in web.config. I don't think it can be done at all.
while you can add a canonical header, to a folder using IIS, you cant add if to a file.
-
He's on a windows server and there is no .htaccess, you use web.config.

Hi, I believe your question is answered here via .htaccess file rather than web.config. Moz blog: How To: Advanced rel="canonical" HTTP Headers

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

Block in robots.txt instead of using canonical?
When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

Yoast & rel canonical for paginated Wordpress URLs
Hello, our Wordpress blog at http://www.jobs.ca/career-resources has a rel canonical issue since we added pagination to the front page and category-pages. We're using Yoast and it's incorrectly applying a rel-canonical meta tag referencing page 1 on page 2, 3, etc. This is a known misuse of the rel-canonical tag (per Google's Webmaster Blog - http://googlewebmastercentral.blogspot.ca/2013/04/5-common-mistakes-with-relcanonical.html, which says rel-canonical should be replaced with rel-prev and rel-next for page 2, 3, etc.). We don't see a way to specify anywhere in Yoast's options to correct this behaviour for page 2, 3, etc. Yoast allows you to override a page's canonical URL, otherwise it automatically uses the Wordpress permalink. My question is, does anyone know how to configure Yoast to properly replace rel-canonical tags with rel-prev and rel-next for paginated URLs, or do I need to look at another plugin or customize the behavior directly in my child theme code? This issue was brought up here as well: http://moz.com/community/q/canonical-help, but the only response did not relate to Yoast. (We're using Wordpress 3.6.1 and Yoast "Wordpress SEO" 1.4.18)

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.

Exact keyword URL or not?
Hi all, I have a quick question about the proper use of permalinks. Let's say that I have a website about sports and I want to create an internal page dedicated to shoes. I know that the keyword "shoe" has 15.000 monthly visits, while the keyword "shoes" has 1.000 monthly visits. How do I have to name the internal page? http://www.example.com/shoe or http://www.example.com/shoes (with a final 's')? I would think that by naming the URL http://www.example.com/shoes, the search engine would consider that page for the keywords "shoe" and "shoes", but I am not sure about it. Should I create a URL that only focuses on one specific keyword ("shoe", in this example) or a URL that may encompass more than one keyword ("shoe" and "shoes")? I hope this is clear. Thank you for your time and help. All best, Sal

Exact match domain names
Hello, Someone approached a client of mine to sell a exact match domain name for a very competitive and high converting keyword. Would this be of any use and what are the best tactics to employ if it is purchased? I was of the opinion that the 'power' of exact match domain names are dying fast but would be interested to hear what people with experience in this think and what they have done with them (i.e. set-up a website on that domain or re-directed it)? Thanks, Rikki
