How to Fix Canonicalization Error

Well, before we fix Canonicalization error, let’s grab some basics understanding about the concept of canonicalization error. This is what we will cover today:

  1. What is Canonicalization
  2. How it impacts Website Authority
  3. How to fix Canonicalization error
  4. Usage of Canonical tag

What is Canonicalization Tag?

Have you ever observed you can access my website with the following URLs:

  1. www.onlineseoblog.com
  2. https://onlineseoblog.com
  3. http://onlineseoblog.com
  4. https://www.onlineseoblog.com

Canonical Tag, also refer as “rel=canonical” helps the search engine to understand which version of the website is the master copy or main copy for a specific piece of content. 

For example, in this case, I have declared Https://www.onlineseoblog.com as canonical URL for my website this will inform search engines https version is the primary URL for this website and hence all the Link Juice and Authority must be provided to this specific URL. 

Issue for Search Engine:

For us, this is as simple as anything type any URL and jump into the website but for Google or any other search engine, this comes under the category of canonicalization error. These varieties of URLs confuse Google which to pick as the main URL and pass Domain Authority (DA) and Page Authority (PA) which in-return improves Page rank.

How Canonicalization Error impacts Website Authority Score:

Let’s take an example to better understand its bad impact on website SEO score.

You can access my website with four different URLs, as an approximation let’s say:

50% of audiences visit https version of the website and rest visit other versions. The same happens during promotion I promoted my https version of a website with more efficiency rather than other versions, the result of which the DA, PA score get divided. 

This would be the stats:

  • Https version

A. DA: 70

B. PA: 60

C. Backlinks: 1000

D.  PR: 10

  • Other versions

A. DA: 20

B. PA: 30

C. Backlink: 100

D. PR: 40

What’s happening here the result of all the efforts is getting distributed among Https and other versions of the website.

This issue of getting end result of all the efforts distributed among different versions of the website falls under the category of Canonicalization Error.
