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

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

Best Practices for Converting PDFs to HTML
We're working with a client who gets about 80% of their organic, inbound search traffic from links to PDF files on their site. Obviously, this isn't ideal, because someone who just downloads a PDF file directly from a Google query is unlikely to interact with the site in any other way. I'm looking to develop a plan to convert those PDF files to HTML content, and try to get at least some of those visitors to convert into subscribers. What's the best way to go about this? My plan so far is: Develop HTML landing pages for each of the popular PDFs, with the content from the PDF, as well as the option to download the PDF with an email signup. Gradually implement 301 redirects for the existing PDFs, and see what that does to our inbound SEO traffic. I don't want to create a dip in traffic, although our current "direct to inbound" traffic is largely useless. Are their things I should watch out for? Will I get penalized by Google for redirecting a PDF to HTML content? Other things I should be aware of?

Adding a Canonical Tag to each page referencing itself?
Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self. I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

Canonical or 301 redirect, that is the question?
So my site has duplicate content issues because of the index.html and the www and non www version of the site. What's the best way to deal with this without htaccess? Is it a 301 redirect or is it the canonical, or is it both?

Rel canonical and duplicate subdomains
Hi, I'm working with a site that has multiple sub domains of entirely duplicate content. So, the production level site that visitors see is (for made-up illustrative example): 123abc456.edu Then, there are sub domains which are used by different developers to work on their own changes to the production site, before those changes are pushed to production: Larry.123abc456.edu Moe.123abc456.edu Curly.123abc456.edu Google ends up indexing these duplicate sub domains, which is of course not good. If we add a canonical tag to the head section of the production page (and therefor all of the duplicate sub domains) will that cause some kind of problem... having a canonical tag on a page pointing to itself? Is it okay to have a canonical tag on a page pointing to that same page? To complete the example... In this example, where our production page is 123abc456.edu, our canonical tag on all pages (this page and therefor the duplicate subdomains) would be: Is that going to be okay and fix this without causing some new problem of a canonical tag pointing to the page it's on? Thanks!

Using exact keyword domains for local SEO
The website is for the attorney that serves several nearby cities. The main page is optimized for the biggest central city. I have several options how to go after the smaller surrounding cities: 1. Create optimized pages inside the main domain 2. Get more or less exact keyword domains for each city e.g. for the city ABC get yourABClawyer.com and then a) use 1 page websites that use the same template as main website and link all the menu items to the main website b)use 1 page website with a link "for more information go to our main website" c) point exact keyword domains to the optimized pages within the main domain. Which option would be the best in terms of SEO and user experience? Would people freak out if they click on the menu item and go to a different domain website even though it uses the same template (option 2a) Would I get more bounces with option 2b in your opinion? Would option 2c have any positive SEO effect? Should I not even bother with exact keyword domain and go with option 1?

Use of the Canonical Tag, Both Internally and Cross Domain
I've seen the cross domain canonical not work at all in my test cases. And an interesting point was brought to my attention today. That point was that in order for the canonical tag to work, the page that you are referencing needs to have the exact same content. And that this was the whole point of the canonical tag, not for it to be used as a 301 but for it to consolidate pages with the same content. I want to know if this is true. Does the page you reference with a canonical tag have to have the same exact content? And what have been your experiences with using the canonical tag referencing another page on a different domain that has the same exact subject matter but not the exact duplicate content?
