      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....

              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.

              How to handle sorting, filtering, and pagination in ecommerce? Canonical is enough?

              Hello, after reading various articles and watching several videos I'm still not sure how to handle faceted navigation (sorting/filtering) and pagination on my ecommerce site. Current indexation status: The number of "real" pages (from my sitemap) - 2.000 pages Google Search Console (Valid) - 8.000 pages Google Search Console (Excluded) - 44.000 pages Additional info: Vast majority of those 50k additional pages (44 + 8 - 2) are pages created by sorting, filtering and pagination. Example of how the URL changes while applying filters/sorting: example.com/category --> example.com/category/1/default/1/pricefrom/100 Every additional page is canonicalized properly, yet as you can see 6k is still indexed. When I enter site:example.com/category in Google it returns at least several results (in most of the cases the main page is on the 1st position). In Google Analytics I can see than ~1.5% of Google traffic comes to the sorted/filtered pages. The number of pages indexed daily (from GSC stats) - 3.000 And so I have a few questions: Is it ok to have those additional pages indexed or will the "real" pages rank higher if those additional would not be indexed? If it's better not to have them indexed should I add "noindex" to sorting/filtering links or add eg. Disallow: /default/ in robots.txt? Or perhaps add "noindex, nofollow" to the links? Google would have then 50k pages less to crawl but perhaps it'd somehow impact my rankings in a negative way? As sorting/filtering is not based on URL parameters I can't add it in GSC. Is there another way of doing that for this filtering/sorting url structure? Thanks in advance, Andrew

              Adding a Canonical Tag to each page referencing itself?

              Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self.  I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

              Do I need to use rel="canonical" on pages with no external links?

              I know having rel="canonical" for each page on my website is not a bad practice... but how necessary is it for pages that don't have any external links pointing to them? I have my own opinions on this, to be fair - but I'd love to get a consensus before I start trying to customize which URLs have/don't have it included. Thank you.

              Should I use rel=canonical on similar product pages.

              I'm thinking of using rel=canonical for similar products on my site. Say I'm selling pens and they are al very similar. I.e. a big pen in blue, a pack of 5 blue bic pens, a pack of 10, 50, 100 etc. should I rel=canonical them all to the best seller as its almost impossible to make the pages unique. (I realise the best I realise these should be attributes and not products but I'm sure you get my point) It seems sensible to have one master canonical page for bic pens on a site that has a great description video content and good images plus linked articles etc rather than loads of duplicate looking pages. love to hear thoughts from the Moz community.

              Are pages with a canonical tag indexed?

              Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

              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 ?

              Any penalty for having rel=canonical tags on every page?

              For some reason every webpage of our website (www.nathosp.com)  has a rel=canonical tag. I'm not sure why the previous SEO manager did this, but we don't have any duplicate content that would require a canonical tag. Should I remove these tags? And if so, what's the advantage - or disadvantage of leaving them in place? Thank you in advance for your help. -Josh Fulfer
