What is non canonical URL?

Hello friends,

What is non canonical URL?

[jayam]

Non-canonical URLs are pages that are either a canonical duplicate of another URL or a duplicate piece of content. ... That means these URLs are being linked to from pages on your site. It also means they are accessible, which is only possible if they are not handled with redirects properly.

[jayammrg]

There are two main ways to fix canonical issues on a website: by implementing 301 redirects, and/or by adding canonical tags to your site's pages to tell Google which of several similar pages is preferred. The right option depends on the canonical issue you're trying to resolve.

A canonical link element, or canonical tag, is found in the HTML header of a webpage and tells search engines if there is a more important version of the page. The canonical tag appears as: rel=”canonical”.
