      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

          OK, thanks for that - I'm still a bit cynical about that amd am pretty sure that doesn't go for a redirect chain but: The reason I asked for the person answering to read the question properly was so that I wouldn't get half an answer

          please could someone read it all the way through and give me their thoughts?

          Thanks.

            Full link juice is now passed through redirects.   Google stopped dinging the value of links that pass through a redirect about a year ago.   More info here....

              Alternate page with proper canonical tag Status: Excluded in Google webmaster tools.

              canonical google webmaster

              In Google Webmaster Tools, I have a coverage issue. I am getting this error message: Alternate page with proper canonical tag Status: Excluded. It gives the below blog post page as an example. Any idea how to resolve? At one time, I was using handl utm grabber, but the plugin is deactivated on my website. https://www.savacations.com/turrialba-costa-ricas-garden-city/?utm_source=deleted&utm_medium=deleted&utm_term=deleted&utm_content=deleted&utm_campaign=deleted&gclid=deleted5.

              Move to new domain using Canonical Tag

              At the moment, I am moving from olddomain.com (niche site) to the newdomain.com (multi-niche site). Due to some reasons, I do not want to use 301 right now and planning to use the canonical pointing to the new domain instead. Would Google rank the new site instead of the old site? From what I have learnt, the canonical tag lets Google know that which is the main source of the contents. Thank you very much!

              Google Ignoring Canonical Tag for Hundreds of Sites

              Bazaar Voice provides a pretty easy-to-use product review solution for websites (especially sites on Magento): https://www.magentocommerce.com/magento-connect/bazaarvoice-conversations-1.html If your product has over a certain number of reviews/questions, the plugin cuts off the number of reviews/questions that appear on the page. To see the reviews/questions that are cut off, you have to click the plugin's next or back function. The next/back buttons' URLs have a parameter of "bvstate....." I have noticed Google is indexing this "bvstate..." URL for hundreds of sites, even with the proper rel canonical tag in place. Here is an example with Microsoft: http://webcache.googleusercontent.com/search?q=cache:zcxT7MRHHREJ:www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Book/productID.325716000%3Fbvstate%3Dpg:8/ct:r+&cd=2&hl=en&ct=clnk&gl=us My website is seeing hundreds of these "bvstate" urls being indexed even though we have a proper rel canonical tag in place. It seems that Google is ignoring the canonical tag. In Webmaster Console, the main source of my duplicate titles/metas in the HTML improvements section is the "bvstate" URLs. I don't necessarily want to block "bvstate" in the robots.txt as it will prohibit Google from seeing the reviews that were cutoff. Same response for prohibiting Google from crawling "bvstate" in Paramters section of Webmaster Console. Should I just keep my fingers crossed that Google honors the rel canonical tag? Home Depot is another site that has this same issue: http://webcache.googleusercontent.com/search?q=cache:k0MBLFcu2PoJ:www.homedepot.com/p/DUROCK-Next-Gen-1-2-in-x-3-ft-x-5-ft-Cement-Board-172965/202263276%23!bvstate%3Dct:r/pg:2/st:p/id:202263276+&cd=1&hl=en&ct=clnk&gl=us

              When is it recommended to use a self referencing rel "canonical"?

              In what type of a situation is it the best type of practice to use a self referencing rel "canonical" tag? Are there particular practices to be cautious of when using a self referencing  rel "canonical" tag? I see this practice used mainly with larger websites but I can't find any information that really explains when is a good time to make use of this practice for SEO purposes. Appreciate all feedback. Thank you in advance.

              Set up a rel canonical

              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

              Include Cross Domain Canonical URL's in Sitemap - Yes or No?

              I have several sites that have cross domain canonical tags setup on similar pages.  I am unsure if these pages that are canonicalized to a different domain should be included in the sitemap.  My first thought is no, because I should only include pages in the sitemap that I want indexed. On the other hand, if I include ALL pages on my site in the sitemap, once Google gets to a page that has a cross domain canonical tag, I'm assuming it will just note that and determine if the canonicalized page is the better version.  I have yet to see any errors in GWT about this.   I have seen errors where I included a 301 redirect in my sitemap file.  I suspect its ok, but to me, it seems that Google would rather not find these URL's in a sitemap, have to crawl them time and time again to determine if they are the best page, even though I'm indicating that this page has a similar page that I'd rather have indexed.

              Rel=canonical tag on original page?

              Afternoon All,
              We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short. We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself? What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original. We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?

              Canonical Tag and Affiliate Links

              Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!
