A canonical tag containing the URL of the webpage is added to the tag of the HTML of the post or page, telling the Google crawler that this is the original URL.

This looks like this:

<link rel="canonical" href=""/>

Yes, it distinguishes between original and duplicate pages.

This initiative was adopted by Google, Microsoft and Yahoo in 2009 to avoid double page ranking and should be used.

But when you should use a canonical tag?

Let's say you have two pages, Page A and Page B, and their URLs are:

Url 1 -

Url 2 -

Both URL A and URL B are the same, but did you notice the difference that one is directly accessible and the other is accessible via a category? , which causes confusion about which URLs should be ranked by search engines.

Don't confuse bots with search engine crawlers. It will ruin your SEO ranking.
