How to Set Canonical Tag to Fix Duplicate Blogspot Blog Post URL Issues?

If you have a Blogspot blog, one of the SEO problems you might see in your blog is having multiple URLs pointing the same post.

Blogger generates different Blog post URLs for both desktop and mobile views. Blogger also creates a different URL that displays with comments.

For example, have a look at the three links I show below.

• https://www.corenetworkz.com/2018/06/redirection-from-m1-blogspot-pages.html
  
  
• https://www.corenetworkz.com/2018/06/redirection-from-m1-blogspot-pages.html?m=1
  
  
• https://www.corenetworkz.com/2018/06/redirection-from-m1-blogspot-pages.html?showComment=1577279824528

If you visit the links, you can see they are pointing to the same post. According to Google Search Quality guidelines, it is a duplicate content issue.

How can we fix the duplicate content issue created by this automatic Blogger post URL generation? The answer is by adding the Canonical tag In the Blogger source code.

By adding a canonical tag, we can tell the search engines which link is the preferred link. Search Engines will avoid other links and save our blogs from the duplicate content issue.

Adding the canonical tag to a static web page is easy. But, how can you add canonical tags on a dynamic website run on Blogger?

It is very simple. I will show you how to add a canonical tag in your Blogger blog.
