What is Canonical URL?
A canonical tag (aka "rel canonical") is a way of telling search engines that a specific URL represents the master copy of a page. Using the canonical tag prevents problems caused by identical or "duplicate" content appearing on multiple URLs.
A Canonical Error arises when 301 redirections are not properly in right place. It means single page URL can open multiple types in the search engine. It breaks the guidelines of Google Webmaster, it makes another copy of your website/page generate content duplicate issues.
A canonical URL sometimes referred to as a "canonical tag," is an HTML attribute that tells search engines where to assign the search value, or "link juice," for pages with duplicate or very similar content.
