What is Canonical URL?

Canonical URL is a representative URL from a set of duplicate pages (duplicate content) on your website. Let's take the following urls as example:


If you open them in your browser, you will see that they both serve the same content. When google crawls those pages, it will discover that those pages have the same content and will discard one of them from its index. We have two options here, either specify which one of those urls will be our canonical URL or let google decide on its own. The best option here for us is to specify the canonical url on our own by adding following html tag in thesection on the page:

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