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....

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

How to add Canonical Tags on Opencart Products
Does anyone know how to add canonical tags to product pages in Opencart? Is this possible to do in htaccess? If so, how specifically should it be written in? Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

Site-wide Canonical Rewrite Rule for Multiple Currency URL Parameters?
Hi Guys, I am currently working with an eCommerce site which has site-wide duplicate content caused by currency URL parameter variations. Example: https://www.marcb.com/ https://www.marcb.com/?setCurrencyId=3 https://www.marcb.com/?setCurrencyId=2 https://www.marcb.com/?setCurrencyId=1 My initial thought is to create a bunch of canonical tags which will pass on link equity to the core URL version. However I was wondering if there was a rule which could be implemented within the .htaccess file that will make the canonical site-wide without being so labour intensive. I also noticed that these URLs are being indexed in Google, so would it be worth setting a site-wide noindex to these variations also? Thanks

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

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.

Partial duplicate content and canonical tags
Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.

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

Canonical VS Rel=Next & Rel=Prev for Paginated Pages
I run an ecommerce site that paginates product pages within Categories/Sub-Categories. Currently, products are not displayed in multiple categories but this will most likely happen as time goes on (in Clearance and Manufacturer Categories). I am unclear as to the proper implementation of Canonical tags and Rel=Next & Rel=Prev tags on paginated pages. I do not have a View All page to use as the Canonical URL so that is not an option. I want to avoid duplicate content issues down the road when products are displayed in multiple categories of the site and have Search Engines index paginated pages. My question is, should I use the Rel=Next & Rel=Prev tags on paginated pages as well as using Page One as the Canonical URL? Also, should I implement the Canonical tag on pages that are not yet paginated (only one page)?
