Rel=Canonical
-
Any downsides to adding the rel=canonical tag to the canonical page itself? It will make it easier for us to implement based on the way our site's templates work.
For example, we would add to the page http://www.mysite.com/original-page.aspx
The canonical tag would also appear on other dupe pages like:
http://www.mysite.com/original-page.aspx?ref=93929299
http://www.mysite.com/original-page.aspx?ref=view29199292
etc

I haven't seen any evidence that it's a problem, but John's point is correct - Bing does officially say not to do it. Actually, Google originally said this, too, but then eased off (if I recall correctly). It's gotten so common that I don't think either engine can really penalize it, honestly. I do it all the time.

Google is definatly OK with this, Bing aparently might have issues, but the only way around that would be implimenting it for all the dupe pages but not the original (which is less trivial to detect, or impossable, and why google allows it)
Due to the nature of the objection (Bing claims your telling it that the page is a duplicate of itself, see the article John linked), I would actualy expect Bing to change that in the future to something more sensable if true.
Overall, I would impliment it on every page just to prevent all those links to it with random tracking paramiters e.t.c. that people could throw on.

IMO that's completely fine. You are passing a directive to Google telling them that whatever versions of that one URL they may come across, the correct URL for them to index, crawl and display in their SERPS is the "original-url". So you are good.

Google doesn't care, but Bing may not like this. Read http://nickroshon.com/seo/google-bing-disagree-on-relcanonical-implementation for more info.

Hi, I have a question relation to Canonical pages That i need clearing up. I am not sure that my bigcommere website is correctly configured and just wanted clarification from someone in the know.

Canonicals & 301 Redirects to new Domain
We will be changing our domain name soon and I want to make sure I'm not painting myself into a corner. Of course, I want to transfer as much link equity as possible. Question #1: Do I need to define a canonical from the old domain to the new domain? Question #2: Do I also need to put 301s in place on the pages with link equity, or is there a way to apply 301s across the entire site on all pages? Any input would be appreciated greatly! Thanks!

Using Canonical URLs option in Platinum SEO for Wordpress
SEOMOZ says that my site has 150 <a title="Click for Help!">Canonical URLs and lists that as a potential problem. It's a check box in the settings for Platinum SEO and here is the description it provides:</a> <a title="Click for Help!">Choose this option to set up canonical URLs for your Home page, Single Post, Category and Tag Pages.</a> I have the option engaged. So I was trying to figure out the best thing to do. I have already instructed it to automatically make 301 redirects for any permalink changes and have instructed it to "noindex" tag archives,rss comment feeds, and rss feeds. I've only been doing this for about a year and am really confused right now. After reading most of your posts about the subject I have a much better understanding, but still very confused. Help..Please...

Blank Canonical URL
So my devs have the canonical URL loaded up on pages automatically, and in most cases this gets done correctly. However we ran across a bug that left some of these blank like so: Does anyone know what effect that would have? I am trying to provide a priority for this so I can say "FIX IT NOW" or "Fix it after the other 'FIX IT NOW' type of items". Let me know if you have any ideas. I just want to be sure I am not telling google that all of these pages are like the home page. Thanks!
