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

Is Canonical Tags a Good Option With 2 Similar Sites?
I have an existing ecommerce site, on a Yahoo platform. I have recently started a different site on the Magento platform with substantially/almost entirely the same products and categories. For various reasons, I won't be ready to do a 301 redirect to the new domain for about another 8 months. I have 4 questions: Is it a good idea to use canonical tags in the meantime? Is there a way to know if the is cannibalization between the sites? They rank for different keywords. Will I lose all traffic and rankings for the Yahoo site if I go the canonical route? If I remove the canonical tags at a later point, will the ranking and traffic of the Yahoo site come back? Thanks in advance for your advice.

Is a Rel Canonical Sufficient or Should I 'NoIndex'
Hey everyone, I know there is literature about this, but I'm always frustrated by technical questions and prefer a direct answer or opinion. Right now, we've got recanonicals set up to deal with parameters caused by filters on our ticketing site. An example is that this: http://www.charged.fm/billy-joel-tickets?location=il&time=day relcanonicals to... http://www.charged.fm/billy-joel-tickets My question is if this is good enough to deal with the duplicate content, or if it should be de-indexed. Assuming so, is the best way to do this by using the Robots.txt? Or do you have to individually 'noindex' these pages? This site has 650k indexed pages and I'm thinking that the majority of these are caused by url parameters, and while they're all canonicaled to the proper place, I am thinking that it would be best to have these de-indexed to clean things up a bit. Thanks for any input.

Should we use the rel-canonical tag?
We have a secure version of our site, as we often gather sensitive business information from our clients. Our https pages have been indexed as well as our http version. Could it still be a problem to have an http and an https version of our site indexed by Google? Is this seen as being a duplicate site? If so can this be resolved with a rel=canonical tag pointing to the http version? Thanks

Multilingual sites: Canonical and Alternate tag implementation question
Hello, I would like some clarification about the correct implementation of the rel="alternate" tag and the canonical tag. The example given at http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077 recommends implementing the canonical tag on all region specific sub-domains, and have it point to the www version of the website Here's the example given by Google. My question is the following. Would this technique also apply if I have region specific sites site local TLD. In other words, if I have www.example.com, www.example.co.uk, www.example.ca – all with the same content in English, but prices and delivery options tailored for US, UK and Canada residents, should I go ahead and implement the canonical tag and alternate tag as follows: I am a bit concerned about canonicalizing an entire local TLD to the .com site.

4 sites on same server with similar theme
Hi, We're building 4 e-commerce stores at the moment which are all very similar. They all sell sofas but to different markets. Product content will be different on each site so the content won't be duplicated but the overall theme of the sites will be the same, all on the same server, being launched at the same time. Should I be concerned that Google may not index all of them? Thanks, Andy

Canonical tag vs 301
What is the reason that 301 is preferred and not rel canonical tag when it comes to implementing redirect. Page rank will be lost in both cases. So, why prefer one over the other ?
