What is Canonical URL?

[RH-Calvin]

<!-- m --><a class="postlink" href="https://www.example.com">https://www.example.com</a><!-- m -->. Pick one of those URLs as your canonical URL and use 301 redirects to send traffic from the other URLs to your preferred URL. A server-side 301 redirect is the best way to ensure that users and search engines are directed to the correct page.
