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

What to do with PDFs that rank well?
Looking at some reports, I found that a client's site has PDFs that are ranking well for niche terms and getting some traffic. What can I do to get more out of them from a marketing standpoint? The obvious issue is that a PDF doesn't have the interactivity of a site visit, where we have analytics and CTAs. Someone has to follow a link back from the PDF to the site for us to even register a visit, let alone try to get their email or have them otherwise convert. My first guess is to make landing page summaries of the PDF content that link to the PDF, and canonical the PDF to the respective landing page. Has anyone tried this, or done something else that they would recommend again in this situation?

Are there any things we have to consider regarding SEO / rankings / duplicate content etc.. with this transition? I hope you have a little spare time to answer this question. Regards,

Absolute vs. Relative Canonical Links
Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice? Should I recommend that all canonical links be absolute? They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

Exact match Title and H1 tags, and over optimization

Can I make 301 redirects on a Windows server (without access to IIS)?
Hey everyone, I've been trying to figure out a way to set up some 301 redirects to handle the broken links left behind after a site restructuring, but I can only ever find information on 2 methods that I can't use (as far as I can tell). The first method is to do some stuff with an htaccess file, but that looks like it only works on Linux-based servers. The method described for Windows servers is generally to install this IIS rewrite/redirect module and run that, but I don't think our web hosting company allows users to log directly into the server, so I wouldn't be able to use the IIS thing. Is there any other way to get a 301 redirect set up? And is this uncommon for a web hosting company to do, or do you all just run your sites on Linux-based servers or your own Windows machines? Thanks!

Redirecting Canonical 301s and Magento Website
I have an issue with a client's website where it has 3700+ pages, but roughly half of them are duplicates. Thankfully, the only difference between the original and the duplictes is the "?print" at the end of each URL (I suppose this is Magento's way of making a printable page version of the same page. I don't know, I didn't build it.) My questions is, how can I get all the pages like this http://www.mycompany.com/blah.html?print to redirect to pages like this... http://www.mycompany.com/blah.html Also, do they NEED to be Canonical, or will a 301 redirect be sufficient. Also, after having done this, if anybody knows, is there a way I can turn that feature off in Magento, because we're expanding our product line, and I don't want to have to keep chasing after these "?print" pages after the fact.

How does a canonical work and is it necessary to also have a no index, follow tag in place?
Across our site, we have canonical tags in place for URLs that contain duplicate content and for URLs without a trailing slash since we are using URLs WITH a trailing slash for all URLs across our site. We also recently added a no index, follow tag to all non-canonical URLs since we noticed a high number of duplicate content URLs in Google Webmaster Tools. The first part of my question is: How does a canonical work? Does the robot read the canonical and immediately go to the canonical URL or does it continue to read past the canonical tag and get to the no index, follow tag if there is one present? The second part of my question is: Is it necessary to have both a canonical tag and no index, follow tag in place? Or should the canonical tag be sufficient to avoid duplicate content? And lastly, if both a canonical tag and no index, follow tag are in place, should they be in a specific order? Canonical tag first then no index, follow tag second or no index, follow tag first then canonical tag second? I would appreciate any insight you can give. Thank you!
