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.

Anyone have any more thoughts on this please?

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....

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)
Intermediate & Advanced SEO | | Andrew_In_Search_of_Answers
• 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!0 -
Pagination parameters and canonical
Hello, We have a site that manages pagination through parameters in urls, this way: friendly-url.html
Intermediate & Advanced SEO | | teconsite
friendly-url.html?p=2
friendly-url.html?p=3
... We've rencently added the canonical tag pointing to friendly-url.html for all paginated results. In search console, we have the "p" parameter identified by google.
Now that the canonical has been added, should we still configure the parameter in search console, and tell google that it is being use for pagination? Thank you!0 -
Should I Keep adding 301s or use a noindex,follow/canonical or a 404 in this situation?
Hi Mozzers, I feel I am facing a double edge sword situation. I am in the process of migrating 4 domains into one. I am in the process of creating URL redirect mapping The pages I am having the most issues are the event pages that are past due but carry some value as they generally have one external followed link. www.example.com/event-2008 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2007 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2006 301 redirect to www.newdomain.com/event-2016 Again these old events aren't necessarily important in terms of link equity but do carry some and at the same time keep adding multiple 301s pointing to the same page may not be a good ideas as it will increase the page speed load time which will affect the new site's performance. If i add a 404 I will lose the bit of equity in those. No index,follow may work since it won't index the old domain nor the page itself but still not 100% sure about it. I am not sure how a canonical would work since it would keep the old domain live. At this point I am not sure which direction I should follow? Thanks for your answers!

Does a non-canonical URL pass link juice?
Our site received a great link from URL A, which was syndicated to URL B. But URL B is canonicalized to URL A. Does the link on URL B pass juice to my site? (See image below for a visual representation of my question) zgbzqBy

Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?
We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

Exact Syntax for Canonical to PDFs for Windows Server
Hi There, I have got in my web several PDFs with the same content of the HTML version. Thus I need to set up a canonical for each of them in order to avoid duplicate content. In particular, I need to know how to write the exact syntax for the windows server (web.config) in order to implement the canonical to PDF. I surfed the web but it seems I cannot find this piece of info anywhere Thanks a lot!!

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.

Canonical link vs root domain
I have a wordpress website installed on http://domain.com/home/ instead of http://domain.com - Does it matter whether I leave it that way with a canonical link from the domain.com to the domain.com/home/ or should I move the wordpress files and database to the root domain?
