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

Canonical questions
Hi, We are working on a site that sells lots of variations of a certain type of product. (Car accessories) So lets say there are 5 products but each product will need a page for each car model so we will potentially have a lot of variations/pages. As there are a lot of car models, these pages will have pretty much the same content, apart from the heading and model details. So the structure will be something like this; Product 1 (landing page) Audi (model selection page)
Intermediate & Advanced SEO | | davidmaxwell
---Audi A1 (Model detail page)
---Audi A2 (Model detail page)
---Audi A3 (Model detail page) BMW (model selection page)
---BMW 1 Series (Model detail page)
---BMW 3 Series (Model detail page) Product 2 (landing page) Audi (model selection page)
---Audi A1 (Model detail page)
---Audi A2 (Model detail page)
---Audi A3 (Model detail page) BMW (model selection page)
etc
etc The structure is like this as we will be targeting each landing page for AdWords campaigns. As all of these pages could look very similar to search engines, will simply setting up each with a canonical be enough? Is there anything else we should do to ensure Google doesn't penalise for duplicate page content? Any thoughts or suggestions most welcome.

Review site using canonical tag in a puzzling way.
Have just been looking at a review site and they're using the canonical tag very strangely, to me. For example, they may have several pages of reviews of the same item - they use the canonical tag on page 2/3/4 to point back at page 1 - and yet there is no duplication between the pages. Any idea why they might be doing this?

How to Set Up Canonical Tags to Eliminate Duplicate Content Error
Google Webmaster Tools under HTML improvements is showing duplicate meta descriptions for 2 similar pages. The 2 pages are for building address. The URL has several pages because there are multiple property listings for this building. The URLs in question are: www.metro-manhattan.com/601-west-26th-street-starrett-lehigh-building-contains-executive-office-space-manhattan/page/3 www.metro-manhattan.com/601-west-26th-street-starrett-lehigh-building-contains-executive-office-space-manhattan How do I correct this error using canonical tags? Do I enter the URL of the 1<sup>st</sup> page under “Canonical URL” under “Advanced” to show Google that these pages are one and the same? If so, do I enter the entire URL into this field (www.metro-manhattan.com /601-west-26th-street-starrett-lehigh-building-contains-executive-office-space-manhattan) or an abbreviated version (/601-west-26th-street-starrett-lehigh-building-contains-executive-office-space-manhattan)? Please see attached images. Thanks!! Alan rUspIzk 34aSQ7k

301 canonical'd pages?
I have an ecommerce site with many different URLs with the same product. Let's say the product is a hat. It's in: a a) mysite.com/products/hat b) mysite.com/collections/head-ware/hat c) mysite.com/collections/stuff-to-wear-on-your-head/hat Right now, A is the canonical page for B and C. I want to clean up my site, so that every product only has ONE unique URL, which is linked to from all the collections. So B and C URL will be broken. Is it necessary that I 301 them if they were already canonical'd? Based on the number of products I have, I would have to 301 1000+ URLs. I'm just trying to figure out what I need to do to avoid getting penalized. thanks

Combining two exact match domains under brand name
I run two websites that sell basically the same product which we make ourselves but to two separate audiences. I've made my living off them for the past 6 years or so. I used emd's in both cases to rank for my main search terms. We dropped a few places last October but not too bad. I was thinking of combining the sites under one brand name hoping that they would rank better combined. Both sites have similar link profiles but with some links unique to each. For instance, I buy a yahoo directory listing for each site but each site has some unique product reviews on blogs. Is this a good idea or am I better off leaving them separate?

Does rel=canonical fix duplicate page titles?
I implemented rel=canonical on our pages which helped a lot, but my latest Moz crawl is still showing lots of duplicate page titles (2,000+). There are other ways to get to this page (depending on what feature you clicked, it will have a different URL) but will have the same page title. Does having rel=canonical in place fix the duplicate page title problem, or do I need to change something else? I was under the impression that the canonical tag would address this by telling the crawler which URL was the URL and the crawler would only use that one for the page title.

Canonical Meta Tag
Can someone explain how this works and how necessary is it? For example, I have a new client, who is ranking WITHOUT the www in their domain, but they have a good deal of backlinks already that have www in it. When I set up google webmaster tools I made 2, one for WWW and one for WITHOUT and there are diffenet numbers of backlinks for each. I have no idea what do about this or if I should even do anything. Thanks

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 ?
