what is canonical url?

[Apptechnologyuk]

Canonical is used to avoid the duplicate content of the website having different URL of same domain. By using the rel= canonical we tell the Google crawler which is the original content and which page should be crawled or index.

A canonical URL is the URL that you want visitors to see. Quite often canonical URLs were used to describe the homepage. The typical example used is that most people treat the following URLs as the same: www.example.com. example.com.
