Rel=canonical and internal links
-
Hi Mozzers,
I was musing about rel=canonical this morning and it occurred to me that I didnt have a good answer to the following question:
- How does applying a rel=canonical on page A referencing page B as the canonical version affect the treatment of the links on page A?
I am thinking of whether those links would get counted twice, or in the case of ver-near-duplicates which may have an extra sentence which includes an extra link, whther that extra link would count towards the internal link graph or not.
I suspect that google would basically ignore all the content on page A and only look to page B taking into account only page Bs links.
Any thoughts?
Thanks!

Thanks a lot for your reply Stephan!
I would be super intertesting to read a little more around the subject. Do you have any studies or cases you might refer me to which describe the flow of link equity to "page C" from "Page A"?
Many thanks

It's an interesting question. I'll extend your example slightly, so that we have:
- Page A, with a canonical pointing to Page B
- Page A also has a regular link to Page C
- Page B does not link to Page C at all
At the crawling stage, Googlebot will parse all of the links on Page A. So in this case it discovers both B and C (if it doesn't know of their existence already). This is uncontroversial stuff—the use of the canonical tag doesn't affect crawling/discovery.
You might then assume that Google—if it decides to obey the canonical instruction, which of course it doesn't always do—will pass all of Page A's link equity to Page B (minus the small fraction), and then no longer count that link from A to C in the link graph. Almost like a redirect, but for bots only.
However, that doesn't seem to happen. The link from A to C is still included in the link graph. PageRank (or whatever's replaced it) may still flow through that link, even though Page A is not to be indexed.
So to answer your original question, the content of Page A will not be ignored, and neither will its links. The unclear bit is how much Google will value that link from A to C.

"Avoid Too Many Internal Links" when you have a mega menu
Using the on-page grader and whilst further investigating internal linking, I'm concerned that as the ecommerce website has a very link heavy mega menu the rule of 100 may be impeding on the contextual links we're creating. Clearly we don't want to no-follow our entire menu. Should we consider no-indexing the third-level- for example short sleeve shirts here... Clothing > Shirts > Short Sleeve Shirts What about other pages we're don't care to index anyway such as the 'login page' the 'cart' the search button? Any thoughts appreciated.

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.

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. Regards Nigel Carousel Projects.

Rankings rise after improving internal linking - then drop again
I'm working on a large scale publishing site. I can increase search rankings almost immediately by improving internal linking to targeted pages, sometimes by 40 positions but after a day or two these same rankings drop down again, not always as low as before but significantly lower than their highest position. My theory is that the uplift generated by the internal linking is subsequently mitigated by other algorithmic factors relating to content quality or site performance or is this unlikely? Does anyone else have experience of this phenomenon or any theories?

Attribution of port number to canonical links...ok?
Hi all A query has recently been raised internally with regard to the use of canonical links. Due to CMS limitations with a client who's CMS is managed by a third party agency, canonical links are currently output with the port number attributed, e.g. example.com/page:80 ...as opposed to the correct absolute URL: example.com/page Note port number are not attributed to the actual page URLs. We have been advised that this canonical link functionality cannot be amended at present. My personal interpretation of canonical link requirements is that such a link should exactly match the absolute URL of the intended destination page, my query is does this extend to the attribution of port number to URLs. Is the likely impact of the inclusion of such potentially incorrect URLs likely to be the same as purely incorrect canonical links. Thanks

Internal links and URL shortners
Hi guys, what are your thoughts using bit.ly links as internal links on blog posts of a website? Some posts have 4/5 bit.ly links going to other pages of our website (noindexed pages). I have nofollowed them so no seo value is lost, also the links are going to noindexed pages so no need to pass seo value directly. However what are your thoughts on how Google will see internal links which have essential become re-direct links? They are bit.ly links going to result pages basically. Am I also to assume the tracking for internal links would also be better using google analytics functionality? is bit.ly accurate for tracking clicks? Any advice much appreciated, I just wanted to double check this.

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.

Yoast & rel canonical for paginated Wordpress URLs
Hello, our Wordpress blog at http://www.jobs.ca/career-resources has a rel canonical issue since we added pagination to the front page and category-pages. We're using Yoast and it's incorrectly applying a rel-canonical meta tag referencing page 1 on page 2, 3, etc. This is a known misuse of the rel-canonical tag (per Google's Webmaster Blog - http://googlewebmastercentral.blogspot.ca/2013/04/5-common-mistakes-with-relcanonical.html, which says rel-canonical should be replaced with rel-prev and rel-next for page 2, 3, etc.). We don't see a way to specify anywhere in Yoast's options to correct this behaviour for page 2, 3, etc. Yoast allows you to override a page's canonical URL, otherwise it automatically uses the Wordpress permalink. My question is, does anyone know how to configure Yoast to properly replace rel-canonical tags with rel-prev and rel-next for paginated URLs, or do I need to look at another plugin or customize the behavior directly in my child theme code? This issue was brought up here as well: http://moz.com/community/q/canonical-help, but the only response did not relate to Yoast. (We're using Wordpress 3.6.1 and Yoast "Wordpress SEO" 1.4.18)
