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....

Change Google's version of Canonical link
Hi My website has millions of URLs and some of the URLs have duplicate versions. We did not set canonical all these years. Now we wanted to implement it and fix all the technical SEO issues. I wanted to consolidate and redirect all the variations of a URL to the highest pageview version and use that as the canonical because all of these variations have the same content. While doing this, I found in Google search console that Google has already selected another variation of URL as canonical and not the highest pageview version. My questions: I have millions of URLs for which I have to do 301 and set canonical. How can I find all the canonical URLs that Google has autoselected? Search Console has a daily quota of 100 or something. Is it possible to override Google's version of Canonical? Meaning, if I set a variation as Canonical and it is different than what Google has already selected, will it change overtime in Search Console? Should I just do a 301 to highest pageview variation of the URL and not set canonicals at all? This way the canonical that Google auto selected might get redirected to the highest pageview variation of the URL. Any advice or help would be greatly appreciated.

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

Is their value in linking to PPC landing pages and using rel="canonical"
I have ppc landing pages that are similar to my seo page. The pages are shorter with less text with a focus on converting visitors further along in the purchase cycle. My questions are: 1. Is there a benefit for having the orphan ppc pages indexed or should I no index them? 2. If indexing does provide benefits, should I create links from my site to the ppc pages or should I just submit them in a sitemap? 3. If indexed, should I use rel="canonical" and point the ppc versions to the appropriate organic page? Thanks,

Why is "Noindex" better than a "Canonical" for Pagination?
"Noindex" is a suggested pagination technique here: http://searchengineland.com/the-latest-greatest-on-seo-pagination-114284, and everyone seems to agree that you shouldn't canonicalize all pages in a series to the first page, but I'd love if someone can explain why "noindex" is better than a canonical?

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.html0 -
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.

Canonical & noindex? Use together
For duplicate pages created by the "print" function, seomoz says its better to use noindex (http://www.seomoz.org/blog/complete-guide-to-rel-canonical-how-to-and-why-not) and JohnMu says its better to use canonical http://www.google.com/support/forum/p/Webmasters/thread?tid=6c18b666a552585d&hl=en What do you think?
