    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....

            Is it best practice to have a canonical tags on all pages

            The website I'm working on has no canonical tags. There is duplicate content so rel=canonicals need adding to certain pages but is it best practice to have a tag on every page ?

            Spammy page with canonical reference to my website

            A potentially spammy website http://www.rofof.com/ has included a rel canonical tag pointing to my website. They've included the tag on thousands of pages on their website. Furthermore http://www.rofof.com/ appears to have backlinks from thousands of other low-value domains For example www.kazamiza.com/vb/kazamiza242122/, along with thousands of other pages on thousands of other domains all link to pages on rofof.com, and the pages they link to on rofof.com are all canonicalized to a page on my site. If Google does respect the canonical tag on rofof.com and treats it as part of my website then the thousands of spammy links that point to rofof.com could be considered as pointing to my website. I'm trying to contact the owner of www.rofof.com hoping to have the canonical tag removed from their website. In the meantime, I've disavowed the www.rofof.com, the site that has canonical tag. Will that have any effect though? Will disavow eliminate the effect of a rel canonical tag on the disavowed domain or does it only affect links on the disavowed website? If it only affects links then should I attempt to disavow all the pages that link to rofof.com? Thanks for reading. I really appreciate any insight you folks can offer.

            302 > 302 > 301 Redirect Chain Issue & Advice

            Hi everyone, I recently relaunched our website and everything went well. However, while checking site health, I found a new redirect chain issue (302 > 302 > 301 > 200) when the user requests the HTTP and non-www version of our URL. Here's what's happening: • 302 #1 -- http://domain.com/example/ 302 redirects to http://domain.com/PnVKV/example/ (the 5 characters in the appended "subfolder" are dynamic and change each time)
            • 302 #2 -- http://domain.com/PnVKV/example/ 302 redirects BACK to http://domain.com/example/
            • 301 #1 -- http://domain.com/example/ 301 redirects to https://www.domain.com/example/ (as it should have done originally)
            • 200 -- https://www.domain.com/example/ resolves properly We're hosted on AWS, and one of my cloud architects investigated and reported GoDaddy was causing the two 302s. That's backed up online by posts like https://stackoverflow.com/questions/46307518/random-5-alpha-character-path-appended-to-requests and https://www.godaddy.com/community/Managing-Domains/My-domain-name-not-resolving-correctly-6-random-characters-are/td-p/60782. I reached out to GoDaddy today, expecting them to say it wasn't a problem on their end, but they actually confirmed this was a known bug (as of September 2017) but there is no timeline for a fix. I asked the first rep I spoke with on the phone to send a summary, and here's what he provided in his own words: From the information gathered on my end and I was able to get from our advanced tech support team, the redirect issue is in a bug report and many examples have been logged with the help of customers, but no log will be made in this case due to the destination URL being met. Most issues being logged are site not resolving properly or resolving errors. I realize the redirect can cause SEO issues with the additional redirects occurring. Also no ETA has been logged for the issue being reported. I do feel for you since I now understand more the SEO issues it can cause. I myself will keep an eye out for the bug report and see if any progress is being made any info outside of this I will email you directly. Thanks. Issue being Experienced: Domains that are set to Go Daddy forwarding IPs may sometimes resolve to a url that has extra characters appended to the end of them. Example: domain1.com forwards to http://www.domain2.com/TLYEZ. However it should just forward to http://www.domain2.com. I think this answers what some Moz users may have been experiencing sporadically, especially this previous thread: https://moz.com/community/q/forwarded-vanity-domains-suddenly-resolving-to-404-with-appended-url-s-ending-in-random-5-characters. My question: Given everything stated above and what we know about the impact of redirect chains on SEO, how severe should I rate this? I told my Director that I would recommend we move away from GoDaddy (something I don't want to do, but feel we _**have **_to do), but she viewed it as just another technical SEO issue and one that didn't necessarily need to be prioritized over others related to the relaunch. How would you respond in my shoes? On a scale of 1 to 10 (10 being the biggest), how big of a technical SEO is this? Would you make it a priority? At the very least, I thought the Moz community would benefit from the GoDaddy confirmation of this issue and knowing about the lack of an ETA on a fix. Thanks!

            Absolute vs. Relative Canonical Links

            Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice?  Should I recommend that all canonical links be absolute?  They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

            Duplicate Title tags even with rel=canonical

            Hello, We were having duplicate content in our blog (a replica of each post automatically was done by the CMS), until we recently implemented a rel=canonical tag to all the duplicate posts (some 5 weeks ago). So far, no duplicate content were been found, but we are still getting duplicate title tags, though the rel=canonical is present. Any idea why is this the case and what can we do to solve it? Thanks in advance for your help. Tej Luchmun

            Canonical tag + HREFLANG vs NOINDEX: Redundant?

            Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

            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.

            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.
