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

How does a page with a canonical for another domain impact SEO?
Hi, We have a requirement to host files that contains .html, .css, .js, and .pdf files externally on AWS S3 bucket. We have a landing page on our site that contains a link to those external links (i.e. pdf). On our site's (hosted on Drupal), landing page we already have a canonical link for the current landing page. On the .html file which is hosted externally, we were thinking to add the same canonical link that exists for the landing page so that search engines will go to the externally available .html file and interpret that the externally hosted file is related to our landing page. I was wondering if this is an acceptable solution without any SEO penalty. If there is a penalty, what would be the alternative solution to this so we can host files externally and drive most of the traffic to our landing page? Example Landing page: absolute url = https://www.site-domain.com/page-url ...... Externally available .html file (static) ......

Google Ignoring Canonical Tag for Hundreds of Sites
Bazaar Voice provides a pretty easy-to-use product review solution for websites (especially sites on Magento): https://www.magentocommerce.com/magento-connect/bazaarvoice-conversations-1.html If your product has over a certain number of reviews/questions, the plugin cuts off the number of reviews/questions that appear on the page. To see the reviews/questions that are cut off, you have to click the plugin's next or back function. The next/back buttons' URLs have a parameter of "bvstate....." I have noticed Google is indexing this "bvstate..." URL for hundreds of sites, even with the proper rel canonical tag in place. Here is an example with Microsoft: http://webcache.googleusercontent.com/search?q=cache:zcxT7MRHHREJ:www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Book/productID.325716000%3Fbvstate%3Dpg:8/ct:r+&cd=2&hl=en&ct=clnk&gl=us My website is seeing hundreds of these "bvstate" urls being indexed even though we have a proper rel canonical tag in place. It seems that Google is ignoring the canonical tag. In Webmaster Console, the main source of my duplicate titles/metas in the HTML improvements section is the "bvstate" URLs. I don't necessarily want to block "bvstate" in the robots.txt as it will prohibit Google from seeing the reviews that were cutoff. Same response for prohibiting Google from crawling "bvstate" in Paramters section of Webmaster Console. Should I just keep my fingers crossed that Google honors the rel canonical tag? Home Depot is another site that has this same issue: http://webcache.googleusercontent.com/search?q=cache:k0MBLFcu2PoJ:www.homedepot.com/p/DUROCK-Next-Gen-1-2-in-x-3-ft-x-5-ft-Cement-Board-172965/202263276%23!bvstate%3Dct:r/pg:2/st:p/id:202263276+&cd=1&hl=en&ct=clnk&gl=us

Canonical page 1 and rel=next/prev
Hi! I'm checking a site that has something like a News section, where they publish some posts, quite similar to a blog.
Intermediate & Advanced SEO | | teconsite
They have a canonical url pointing to the page=1. I was thinking of implementing the rel=next/ prev and the view all page and set the view all page as the canonical. But, as this is not a category page of an ecommerce site, and it would has more than 100 posts inside in less than a year, It made me think that maybe the best solution would be the following Implementing rel=next/prev
Keep page 1 as the canonical version. I don't want to make the users wait for a such a big page to load (a view all with more than 100 elements would be too much, I think) What do you think about this solution? Thank you!0 -
This is a clear-cut canonical issue, right?
Hello, A client is having one of their daily blogs published on a industry news site along with on their own site. This is a clear-cut case of having a canonical tag implemented on the client's site on each blog page, right? Thanks

Rel Canonical Syntax
My IT department is getting ready to setup the rel canonical tag, finally. I took a look at the code on our test server and see that they are using a single quote in the tag syntax (see code block below). Should I be concerned? Will Google read those lines the same? <link rel='canonical' href='[http://www.wholesalecostumeclub.com/easter-costumes/bunny-suits](view-source:http://www.wholesalecostumeclub.com/easter-costumes/bunny-suits)' />VS. **versus** <link rel="canonical" href="[http://www.wholesalecostumeclub.com/easter-costumes/bunny-suits](view-source:http://www.wholesalecostumeclub.com/easter-costumes/bunny-suits)" />

Should I be using rel canonical here?
I am reorganizing the data on my informational site in a drilldown menu. So, here's an example. One the home page are several different items. Let's say you clicked on "Back Problems". Then, you would get a menu that says: Disc problems, Pain relief, paralysis issues, see all back articles. Each of those pages will have a list of articles that suit. Some articles will appear on more than one page. Should I be worried about these pages being partially duplicates of each other? Should I use rel-canonical to make the root page for each section the one that is indexed. I'm thinking no, because I think it would be good to have all of these pages indexed. But then, that's why I'm asking!
