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....

In Google Webmaster Tools, I have a coverage issue. I am getting this error message: Alternate page with proper canonical tag Status: Excluded. It gives the below blog post page as an example.

Landing pages for paid traffic and the use of noindex vs canonical
A client of mine has a lot of differentiated landing pages with only a few changes on each, but with the same intent and goal as the generic version. The generic version of the landing page is included in navigation, sitemap and is indexed on Google. The purpose of the differentiated landing pages is to include the city and some minor changes in the text/imagery to best fit the Adwords text. Other than that, the intent and purpose of the pages are the same as the main / generic page. They are not to be indexed, nor am I trying to have hidden pages linking to the generic and indexed one (I'm not going the blackhat way). So – I want to avoid that the duplicate landing pages are being indexed (obviously), but I'm not sure if I should use noindex (nofollow as well?) or rel=canonical, since these landing pages are localized campaign versions of the generic page with more or less only paid traffic to them. I don't want to be accidentally penalized, but I still need the generic / main page to rank as high as possible... What would be your recommendation on this issue?

Ecommerce: A product in multiple categories with a canonical to create a ‘cluster’ in one primary category Vs. a single listing at root level with dynamic breadcrumb.
OK – bear with me on this… I am working on some pretty large ecommerce websites (50,000 + products) where it is appropriate for some individual products to be placed within multiple categories / sub-categories. For example, a Red Polo T-shirt could be placed within: Men’s > T-shirts >
Intermediate & Advanced SEO | | AbsoluteDesign
Men’s > T-shirts > Red T-shirts
Men’s > T-shirts > Polo T-shirts
Men’s > Sale > T-shirts
Etc. We’re getting great organic results for our general T-shirt page (for example) by clustering creative content within its structure – Top 10 tips on wearing a t-shirt (obviously not, but you get the idea). My instinct tells me to replicate this with products too. So, of all the location mentioned above, make sure all polo shirts (no matter what colour) have a canonical set within Men’s > T-shirts > Polo T-shirts. The presumption is that this will help build the authority of the Polo T-shirts page – this obviously presumes “Polo Shirts” get more search volume than “Red T-shirts”. My presumption why this is the best option is because it is very difficult to manage, particularly with a large inventory. And, from experience, taking the time and being meticulous when it comes to SEO is the only way to achieve success. From an administration point of view, it is a lot easier to have all product URLs at the root level and develop a dynamic breadcrumb trail – so all roads can lead to that one instance of the product. There's No need for canonicals; no need for ecommerce managers to remember which primary category to assign product types to; keeping everything at root level also means there no reason to worry about redirects if product move from sub-category to sub-category etc. What do you think is the best approach? Do 1000s of canonicals and redirect look ‘messy’ to a search engine overtime? Any thoughts and insights greatly received.0 -
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

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!!

[E-commerce] Duplicate content due to color variations (canonical/indexing)
Hello, We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content. What we have done so far: Choosing the best-selling color variation (our "master product") Adding a rel="canonical" to every variation (with our "master product" as the canonical URL) In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do? Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change) 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?
