What is 301 Redirect?

A 301 Redirect is a process when search engine and web browser get an information about a web page or website relocation. It is a permanent redirection from one URL to another.

A 301 Redirect also contains a new different URL. Web user does not need to do any action. Web browser follows the 301 Redirect and user is automatically redirected to a new place. So, a 301 Redirect is used every time, when the website's URL changes.
