A 301 Redirect is an Internet page that comes up commonly on the Internet. This is a form of URL redirection that allows a website to inform visitors that the website once at the current URL has moved to a different address. This type of URL redirection is classified as a 301 Redirect because the website at the particular URL address in question has been permanently moved to a new address, and there will no longer be any connection between the old address and the new URL address. In HTTP computer protocol, a 301 Redirect is called a response with a status code that induces a browser to arrive at a different location. All of these similar status codes begin with a 3.

There are many different reasons that a website may choose to use a 301 Redirect to signify a permanent change to the location of a website.

These reasons can include:

• The website is at a similar but distinctly different domain name
• Two websites are merging into one page
• There is a completely new address for the website

Redirection services may also use 301 Redirect pages to shorten long URLs, though many experts argue about the validity of this use of 301 Redirect pages.
