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....

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!

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.

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 -
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

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 - but Title and Description are slightly different
I am building a new SEO site with a "Silo" / Themed architecture. I have a travel website selling hotel reservations. I list a hotel page under a city page - example, www.abc.com/Dallas/Hilton.html Then I use that same property under a segment within the city - example www.abc.com/Dallas/Downtown/Hilton.html, so there are two URLs with the same content Both pages are identical, except I want to customize the Title and Description. I want to customize the title and description to build a consistent theme - for example the /Downtown/Hilton page will have the words "Near Downtown" in the Title and Description, while the primary city Hilton page will not. So I have two questions about this. First, is it okay to use a canonical tag if the Title and Description are slightly different? Everything else is identical. If so, will Google crawl and comprehend the unique Title and Description on the "Downtown" silo? I want Google to see that I have several "supporting" pages to my main landing page(s). I want to present to Google 5 supporting pages in each silo that each has a supporting keyword theme. But I'm not sure if Google will consider content of pages that point to a different page using the canonical tag. Please see this supporting example: http://d.pr/i/aQPv Thanks for your insights. Rob

Rel=canonical tag on original page?
Afternoon All,
Intermediate & Advanced SEO | | Jellyfish-Agency
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?0 -
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?
