seo – Duplicate content, canonical url and json-ld Article

If I have a duplicate content, which URLs should I use in json-ld Article schema? To be precise, let’s say I want to publish an article from my on another site e.g. When I publish the article on I go and update canonical URL on my, and og:url property (both should be same as implied here):

<!-- this is on -->
<link rel="canonical" href="">
<meta property="og:url" content="" />

I also use to describe the Article entity, however, usually all URLs within it point to my own

<!-- this is on -->
<script type="application/ld+json">
    "@context": "",
    "@type": "Article",
    "author": {
      "name" : "Gitnik"
    "headline": "My Duplicate Article",
    "description" : "Uhm, how do I deal with Article entity in case of duplicate content?",
    "inLanguage" : "en",
    "wordCount":  600 ,
    "datePublished" : "2020-05-18T21:00:00",
    "dateModified" : "2020-05-18T21:00:00",
    "image" : "",
    "mainEntityOfPage" : "",
    "publisher" : {
      "@type": "Organization",
      "name" : "",
      "logo" : {
          "@type" : "ImageObject",
          "url" : "",
          "height" :  60 ,
          "width" :  60

but Google states that mainEntityOfPage should be same as canonical URL. Now, it’s easy to update mainEntityOfPage to the new url. But what about image url and organization? Can image url point to a location other than canonical url? And should I change Organization entity to the and change the url there also? How would it affect SEO if I left them unchanged? How would it affect SEO if I left mainEntityOfPage unchanged?

Set Canonical URL to GIF for Facebook

I’m creating a gif hosting user frontend submission site. For Facebook to correctly animate a GIF on their platform, the og meta tag needs to be redirected to the specific gif. I can remedy this by manually adding the gif url as the canonical link and it will work.

However, dynamic posts from multiple users, I will need to reference that gif as canonical in order for it to work.

What would be the best method to do this?

Knowledge – Are there canonical examples of texts written in Elvish?

I am referring to the Elvish language of the Forgotten Realms, generally written in the script Espruar. Are there examples of messages, poems, paragraphs, …? More specifically, those that make sense in the language, not just random letters from the Espruar script.

zfs – How to update initramfs in canonical kernel livepatch?

When testing the latest ZFS for root file system on Ubuntu 20.04 LTS with Canonical livepatch kernel, how do you update initramfs to limit the maximum size of ZFS ARC?

$ sudo vim /etc/modprobe.d/zfs.conf 
options zfs zfs_arc_min=536870912
options zfs zfs_arc_max=1073741824
$ sudo update-initramfs -u

I noticed the bpool keeping / boot missing, and issued update-initramfs -u produced nothing at all. After restarting, the minimum and maximum sizes of ZFS ARC did not change.

$ sudo arc_summary | grep -A2 "ARC size (current):"
ARC size (current):                            45.2 %    1.8 GiB
Target size (adaptive):                       100.0 %    4.0 GiB
Min size (hard limit):                         25.0 %    1.0 GiB

seo – Redirect 301 from local TLD to .com or canonical for a multi-domain strategy

The best approach for a multi-domain strategy for ranking purposes

I have a domain with a local TLD; and I've been trying to rank for a while with some keywords I think I have much better content than the rest, but the rest uses EDM (exact domain match), so I think you should do the same.

So the strategy would be to redirect with 301 since to

I've also read that a 301 redirect should be the best option, but redirecting ".com" from TLD to ".org" would cause a loss of juice by the tank. So I wonder if it is the same case to redirect with 301 from ".cl"yet".com"

Another strategy I'm thinking of is adding a cannonical link in www.example/mykeyword point at and keep both contents until Google classifies the new domain.

What do you think about these two strategies and what do you think about redirecting to different TLDs?

Thank you.

seo: is it okay to have such a canonical desktop url when googlebot is crawling like smartphone?

Google in the search console has clearly stated that it is indexing as a smartphone. Our redirect logic looks at the user agent and redirects all mobile traffic to the mobile URL. However, in the header of our mobile site, our canonical URL is from the desktop site. This according to the Google documentation here, you must indicate it as the main URL for Googlebot and identify the canonical based primary content. According to the link, Googlebot tries to crawl main content more frequently.

Will our redirect to the mobile and canonical site with desktop URLs create an infinite loop for the Google robot? Is there any chance that Googlebot crawls our site less often since the link it receives is a mobile URL and says it is an alternate URL in its header?

Some quick configuration information, to set the context of the question:

  1. Both the main domain and the mobile domains are subdomains. (For example: and
  2. Google's search console says it is indexing like a smartphone on the console.
  3. Mobile traffic to the desktop site is automatically redirected to the mobile URL. However, desktop traffic to a mobile URL is not redirected backwards.
  4. On the desktop site, canonical is the url of the desktop itself. E.g: . Apart from that, the alternative link also receives a header with a link to the mobile site. E.g:
  5. On the mobile website, the canonical URL points to the desktop site.
  6. Google search results show mobile URLs in mobile search and desktop URLs in desktop search.

seo – Page with links to other pages that have their canonical URLs set to the URL of the original page

My website has a page A which shows some search results, each as a separate link. Clicking on a link will open a new page B_link where the only thing that happens is to redirect the user to another website (the location of the page changes in Javascript). The problem is that these intermediate pages B_link (which are used for redirection) are indexed by Google, which doesn't help, as they simply redirect the user to another website.

One option would be to not index those pages at all, but this means you would waste precious search engine indexing. So I wonder if it's okay to set the canonical URL for B_link Pages to the URL of the original search results page A.

I'm thinking that if I do, then the search results page A you will end up having links to pages with the canonical URL set to your own URL (the URL of A), which looks like a loop to me. Do search engines agree to this?

Where can I find a canonical list of the latest firmware for Canon cameras?

Is there a list somewhere that indicates the latest firmware for different Canon EOS cameras? Having many different bodies would go a long way in not having to go through each product page one by one.

seo – Correct use of canonical when using URL parameters?

On certain pages of my website I use URL parameters in the links:

Click here

The destination URL is always exactly the same (i.e. / example /).
With exactly the same content.

The URL parameter is only to be used as a hidden form field in a form on that page. In order to identify the page that the user has visited before submitting that form.

My question:
How do I correctly configure the canonical to prevent the landing page from being indexed multiple times?

Just on the actual landing page in your head like this?

Or should I do it in the actual original link too?
How would you ideally solve this?

Currently, the tool claims that those pages are "Duplicate pages without canonical", although I have already configured the self-referenced canonical on the landing page in this way .

Canonical URL: Why would canonized URLs get organic traffic?

I have a set of pages in a subdomain that have rel='canonical' links to my main domain. They have content very similar to each of the pages they are canonized to, but I want them to remain accessible, only not to be shown in SERPs.

In GA I am seeing that they have around 300 organic sessions in the last 3 months.

I thought canonicalizing them on another page made them non-indexable.

I can make them appear in SERPs if I do a search on the site:, and similarly if I search for their main keyword when I do a search on the site:

However, I don't think it's likely that there will be so many people searching that way. What do you think about why those pages get organic traffic?
