Cannonical Tags and Backlinking Relationship Problem

If the content in Medium.com has a backlink to your website's page then only it will be counted as a backlink. Only content will not be treated as backlink of your website. Better, start having backlinks from the Medium Blog.

Sorry, i couldn't understand. I wrote the same content in the Medium but i gave a cannonical tag in medium blog for the original blog article that is in my web site page.

Is everything okay like this way?

Also, i can't find every backlinks in google search console. Do u know why?

Yes @Cahit, everything is fine in that way.

The backlinks from noindex, nofollow type of pages are not shown in Google Search Console. That means, please check whether such linking pages are crawlable or not.

crawlable linking pages that you meant are on my web site right? they might be nofollow, noindex etc.

No. The web page from where your website is linked can be noindex, nofollow etc.

So, you mean medium?

Yes, we can say so.

what is interesting that i can see just one backlink which is from medium on google search console.

And why the blog articles that i wrote on medium are onfollow, nofollow etc. Is it something that Medium has set to?

Yes, the Medium set it so. You can find more information here,
