What are Canonical Links? Please explain?

The reason I ask this question is because I have started cross posting my content from my mommy blog to Medium and the plugin that is used to do this by Medium ensures that the SEO is good by using canonical links.

I don't 100% understand how that all works?

The reason I want to know is that I am interested in cross posting some of the content from some of my other blogs to my mommy blog and then also have that cross posted to Medium.

If I add the original content's url into my SEO plugin as the canonical link would that be sufficient to ensure good seo? So the Medium blog would point to my mommy blog and in turn my mommy blog would point to my other blog...

Any thoughts on this please?

Well, the canonical URL is an HTML element. It was introduced to HTML back in April 2012 and is a way to prevent duplicate content issues. By specifying the canonical URL (preferred URL) of a web page it lets Search Engines know which web page the content belongs to.

Back before the canonical URL, Search Engines used to find it problematic to know the original source that content belongs to. Especially when one piece of content can have multiple different URLs.

As an example say you have http://www.yoursite.com/a-web-page.html
And you could also access that page with the URL http://www.yoursite.com/a-web-page.html?parameter=1

The Search Engines would think that the other URL is a different page. But they're not. They're the same page. But they just have different URLs.

So the canonical URL was released so that a webmaster could specify which URL is the main or preferred URL for that web page.

So that's basically the canonical URL, why we have it and how it's used.

Hope this helps!

Thanks Mike, so I cross post some of my addiction posts to my mommy blog and just put the link to the post on my addiction website in the Canonical Url section of All In One SEO?

That would work right?

Yeah well the Canonical URL is automatically created and set for you when you publish the post. There is nothing that you need to do. Allinone SEO pack handles it for you. What are Canonical Links? Please explain?

Thats how I understand it anyway. I think that's right but might have to research that!

Hope it helps Lynne my esteemed colleague and friend.

Mike

This is the first time that I’ve heard of canonical link. For a newcomer to SEO like me, it is easy to get confused with the new terms that I encounter and that is the reason why I try to extract the meaning that I can understand because sometimes the explanations are too technical that my simple mind couldn’t comprehend. It looks like the canonical URL is the same URL as the main?
