      I have a question. I was wondering, if it was possible to set up a rel canonical. When I can't access the non canonical pages? For example, my site as at www.site.com , but the non cannocail is at site.com is their any way to set thet up without actually edting it at site.com ? Thanks for your help

        site.com and site.com/index.html are both loading index.html  So open Index.html, add the canonical tag back to your preferred version and you're done.

        If you're saying that you want the link to be something different, that depends on how the site is setup, whether you can change the "home" button or whatnot. In Wordpress's new menus this is simple. In other themes, not so much. In other CMS, I don't know because "it depends."

          Hi Matt,

          Yes the duplicate is coming from index.html . So, when you click back to the homepage it goes to that. How would you suggest I get rid of that? Thanks for your help.

            I'm confused. Assuming your site is at www.site.com and site.com, the duplicate is coming from a file, usually index.html or index.php, yes?  But it's the same index.html file.  So if you setup rel=canonical in index.html, both site.com and www.site.com will have a canonical on it.

            (Or I'm missing something.)

              If there's no way to access site.com why will you set a canonical?

              If, for example, your sites serves the same content on site.com and www.site.com what you need is a "global" 301 redirect from site.com to www.site.com to avoid duplicate issues. As the file is the same in both domains, a canonical would help, but not appropriate in that case.

              Is that what you need?

                Canonical Chain

                This is quite advanced so maybe Rand can give me an answer? I often have seen questions surrounding a 301 chain where only 85% of the link juice is passed on to the first target and 85% of that to the next one, up to three targets. But how about a canonical chain? What do I mean by this:? I have a client who sells lighting so I will use a real example (sans domain) I don't want 'new-product' pages appearing in SERPS. They dilute link equity for the categories they replicate and often contain identical products to the main categories and subcategories. I don't want to no index them all together I'd rather tell Google they are the same as the higher category/sub category. (discussion whether a noindex/follow tag would be better?) If I canonicalize new-products/ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 to /ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 I then subsequently discover that everything in kitchen-ceiling-lights-c217 is already in /kitchen-lighting-c17 and I decide to canonicalize those two - so I place a /kitchen-lighting-c17 canonical on /kitchen-ceiling-lights-c217. Then what happens to the new-products canonical? Is it the same rule - does it pass 85% of link equity back to the non new-product URL and 85% of that back to the category? does it just not work? or should I do noindexi/follow Now before you jump in: Let's assume these are done over a period of time because the obvious answer is: Canonicalize both back to /ceiling-lights-c1/kitchen-lighting-c17 I know that and that is not what I am asking. What if they are done in a sequence what is the real result? I don't want to patronise anyone but please read this carefully before giving an answer. Regards Nigel Carousel Projects.

                Should pages with rel="canonical" be put in a sitemap?

                I am working on an ecommerce site and I am going to add different views to the category pages. The views will all have different urls so I would like to add the rel="canonical" tag to them. Should I still add these pages to the sitemap?

                Block in robots.txt instead of using canonical?

                When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

                Yoast & rel canonical for paginated Wordpress URLs

                Hello, our Wordpress blog at http://www.jobs.ca/career-resources has a rel canonical issue since we added pagination to the front page and category-pages. We're using Yoast and it's incorrectly applying a rel-canonical meta tag referencing page 1 on page 2, 3, etc. This is a known misuse of the rel-canonical tag (per Google's Webmaster Blog - http://googlewebmastercentral.blogspot.ca/2013/04/5-common-mistakes-with-relcanonical.html, which says rel-canonical should be replaced with rel-prev and rel-next for page 2, 3, etc.). We don't see a way to specify anywhere in Yoast's options to correct this behaviour for page 2, 3, etc. Yoast allows you to override a page's canonical URL, otherwise it automatically uses the Wordpress permalink. My question is, does anyone know how to configure Yoast to properly replace rel-canonical tags with rel-prev and rel-next for paginated URLs, or do I need to look at another plugin or customize the behavior directly in my child theme code? This issue was brought up here as well: http://moz.com/community/q/canonical-help, but the only response did not relate to Yoast. (We're using Wordpress 3.6.1 and Yoast "Wordpress SEO" 1.4.18)

                Rel="canonical" and rel="alternate" both necessary?

                We are fighting some duplicate content issues across multiple domains. We have a few magento stores that have different country codes. For example: domain.com and domain.ca, domain.com is the "main" domain. We have set up different rel="alternative codes like: The question is, do we need to add custom rel="canonical" tags to domain.ca that points to domain.com? For example for domain.ca/product.html to point to: Also how far does rel="canonical" follow?  For example if we have:
                domain.ca/sub/product.html canonical to domain.com/sub/product.html
                then,
                domain.com/sub/product.html canonical to domain.com/product.html

                Wildcard Redirects & Canonical Tags

                I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
                www.domain.com/red-widgets-cid-1234-1.html
                www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234.html New URL:
                www.domain.com/red-widgets-cid-4567.html Current URLs Example2: www.domain.com/red-widgets-cid-1234+10.html
                www.domain.com/red-widgets-cid-1234+10-1.html
                www.domain.com/red-widgets-cid-1234+10-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234+10.html New URL:
                www.domain.com/red-widgets-cid-6789.html Current URLs Example3: www.domain.com/red-widgets-cid-1234+10+5.html
                www.domain.com/red-widgets-cid-1234+10+5-1.html
                www.domain.com/red-widgets-cid-1234+10+5-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234+10+5.html New URL:
                www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs.  However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?

                Do I need to use canonicals if I will be using 301's?

                I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/
                http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx (I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: http://www.omnipress.com/boss-man" /> With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!

                Is it ok to use both 301 redirect and rel="canonical' at the same time?

                Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!
