Rel=canonical
-
I have seen that almost all of my website pages need rel=canonical tag.
Seems that something's wrong here since I have unique content to every page.
Even show the homepage as a rel=canonical which doesnt make sense.
Can anyone suggest anything? or just ignore those issues.

Thank you. i have set it to all pages but i will have a look for any duplicates by using Xenu program.

You can implement it side wide on all pages, but make sure that you do it correctly. One other added benefit is that if anyone scrapes your content, if they scrape the code that includes your canonical link, you would get proper attribution.
Also, if you do it site wide, on any pages where you do want the canonical pointing to another page, make sure that you don't overwrite those. Example, you may have the printer friendly version of a page canonical to the original version of the page - this makes sense and is a good use of canonical. You would not want to overwrite that canonical with the canonical to self.
Cheers!

Thanks,
Okay so you recommend add rel canonical only for homepage right?

The link that kosta list relates to the use of the rel=canonical for multi lingual pages.
I would point you to Dr. Pete (below) and I think he has good advice. I also love to eat cannonscicles, but that is another story. Generally, you can do it, but you need to know what you are doing to make sure that you do not screw something up.
I had an issue on a site where Google was still caching old URLs on our site, even though we had relaunched the URL structure and setup 301 redirects - over two years prior. An SEO consultant we work with suggested dropping in the self canonicalizing (sp?) links and over a period of a couple of months the old URLs were replaced in the Google SERPs and GWT report pages.
Cheers!

"(6) Is It OK to Put Rel=Canonical on My Entire Site?
Should you pre-emptively rel=canonical your entire site – even if many of the pages aren’t subject to duplicate content issues? I think this gets very speculative. We have recommended this approach at SEOmoz in the past, and I think it’s generally safe. I do worry that excessive use of rel=canonical could cause search engines to devalue and even ignore those tags, but I can’t point to any clear evidence of this happening. I also worry that people often implement site-wide rel=canonical tags badly, and end up pointing them to the wrong pages.
I do think that a pre-emptive rel=canonical on your home-page is generally a good ideas, as home pages are prone to URL variations. In a perfect world, I’d say to use rel=canonical on the home-page, known duplicates, and any pages with parameters that could drive duplicate content, and leave the rest alone. However, that’s often a very difficult procedure. In some cases, site-wide rel=canonical implementation is better than no index control."

should i use on every page since its a unique page?
or dont use it at all.
How about this ?

**Update: to simplify implementation, we no longer recommend using rel=canonical.
A bit of confusion.

Canonical URL's For Two Domains
We have two websites, one we use for Google PPC (website 1) and one (website 2) we use for everything else. The reason is we are in an industry that Google Adwords doesn't like, so we built a whole other website that removes the product descriptions as Google Adwords doesn't approve of many of them (nutrition). Right now we have that Google Adwords approved website (website 1) no-index/no-follow because we didn't want to run into potential duplicate content issues in free search, but the issue is we can't submit it to Google Shopping...as they require it to be indexable. Do you think removing the no-index/no-follow from that website 1 and adding canonical URL's pointing to website 2 would resolve this issue (being able to submit it to Google Shopping) and not cause any problems with duplicate content? I was thinking of adding the canonical tag to all pages of website 1 and point it to website 2. Does that make sense? Do you think that would work?

Site-wide Canonical Rewrite Rule for Multiple Currency URL Parameters?
Hi Guys, I am currently working with an eCommerce site which has site-wide duplicate content caused by currency URL parameter variations. Example: https://www.marcb.com/ https://www.marcb.com/?setCurrencyId=3 https://www.marcb.com/?setCurrencyId=2 https://www.marcb.com/?setCurrencyId=1 My initial thought is to create a bunch of canonical tags which will pass on link equity to the core URL version. However I was wondering if there was a rule which could be implemented within the .htaccess file that will make the canonical site-wide without being so labour intensive. I also noticed that these URLs are being indexed in Google, so would it be worth setting a site-wide noindex to these variations also? Thanks

301s Or Stick With Canonical?
Hello all! A nice interesting one for you on this fine Friday... I have some pages which are accessible by 2 different urls - This is for user experience allowing the user to get to these pages in two different ways. To keep Google happy we have a rel canonical so that Google only sees one of these urls to avoid duplicates. After some SEO work I need to change both of these urls (on around 1,000 pages). Is the best way to do this... To 301 every old url to every new url Or... To not worry as I will just point the indexed pages to the new rel canonical? Any ideas or suggestions would be brilliant. Thanks!

Cross Domain Rel Canonical tags vs. Rel Canonical Tags for internal webpages
Today I noticed that one of my colleagues was pointing rel canonical tags to a third party domain on a few specific pages on a client's website. This was a standard rel canonical tag that was written Up to this point I haven't seen too many webmasters point a rel canonical to a third party domain. However after doing some reading in the Google Webmaster Tools blog I realized that cross domain rel canonicals are indeed a viable strategy to avoid duplicate content. My question is this; should rel canonical tags be written the same way when dealing with internal duplicate content vs. external duplicate content? Would a rel=author tag be more appropriate when addressing 3rd party website duplicate content issues? Any feedback would be appreciated.

Should you use a canonical tag on translated content in a multi-language country?
A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
Intermediate & Advanced SEO | | Zanox
At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???0 -

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!

Could adding canonical tags to large Ecommerce site ever hurt rankings? Temporarily?
We have a really large site we're working on who's product pages rank well for the most part but also have multiple products listed in different categories with different URL's. I'm assuming there's no downside to adding canonical tags to these right? Its peak season so I don't want to do anything that could, even temporarily, bring down their rankings. Thanks!
