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.

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

Over-optimizing Internal Linking: Is this real and, if so, what's the happy medium?
I have heard a lot about having a solid internal linking structure so that Google can easily discover pages and understand your page hierarchies and correlations and equity can be passed. Often, it's mentioned that it's good to have optimized anchor text, but not too optimized. You hear a lot of warnings about how over-optimization can be perceived as spammy: https://neilpatel.com/blog/avoid-over-optimizing/ But you also see posts and news like this saying that the internal link over-optimization warnings are unfounded or outdated:

https://www.seroundtable.com/google-no-internal-linking-overoptimization-penalty-27092.html So what's the tea? Is internal linking overoptimization a myth? If it's true, what's the tipping point? Does it have to be super invasive and keyword stuffy to negatively impact rankings? Or does simple light optimization of internal links on every page trigger this?1 -
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.

Switching from HTTP to HTTPS: 301 redirect or keep both & rel canonical?
Hey Mozzers, I'll be moving several sites from HTTP to HTTPS in the coming weeks (same brand, multiple ccTLDs). We'll start on a low traffic site and test it for 2-4 weeks to see the impact before rolling out across all 8 sites. Ideally, I'd like to simply 301 redirect the HTTP version page to the HTTPS version of the page (to get that potential SEO rankings boost). However, I'm concerned about the potential drop in rankings, links and traffic. I'm thinking of alternative ways and so instead of the 301 redirect approach, I would keep both sites live and accessible, and then add rel canonical on the HTTPS pages to point towards HTTP so that Google keeps the current pages/ links/ indexed as they are today (in this case, HTTPS is more UX than for SEO). Has anyone tried the rel canonical approach, and if so, what were the results? Do you recommend it? Also, for those who have implemented HTTPS, how long did it take for Google to index those pages over the older HTTP pages?

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

Link Juice + multiple links pointing to the same page
Scenario
Intermediate & Advanced SEO | | Mark_Ch
The website has a menu consisting of 4 links Home | Shoes | About Us | Contact Us Additionally within the body content we write about various shoe types. We create a link with the anchor text "Shoes" pointing to www.mydomain.co.uk/shoes In this simple example, we have 2 instances of the same link pointing to the same url location.
We have 4 unique links.
In total we have 5 on page links. Question
How many links would Google count as part of the link juice model?
How would the link juice be weighted in terms of percentages?
If changing the anchor text in the body content to say "fashion shoes" have a different impact? Any other advise or best practice would be appreciated. Thanks Mark0 -
Should I use rel=canonical on similar product pages.
I'm thinking of using rel=canonical for similar products on my site. Say I'm selling pens and they are al very similar. I.e. a big pen in blue, a pack of 5 blue bic pens, a pack of 10, 50, 100 etc. should I rel=canonical them all to the best seller as its almost impossible to make the pages unique. (I realise the best I realise these should be attributes and not products but I'm sure you get my point) It seems sensible to have one master canonical page for bic pens on a site that has a great description video content and good images plus linked articles etc rather than loads of duplicate looking pages. love to hear thoughts from the Moz community.

Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam
