What is Canonical URL?
The rel=canonical element often called the “canonical link”, is an HTML element that helps webmasters prevent duplicate content issues. It does this by specifying the “canonical URL”, the “preferred” version of a web page – the original source, even. Using it well improves a site's SEO
Canonical URLs are on the page and define which url the page should be indexed as. This is used when you have one or more url parameters that might resolve that same content.
