What is a 301 Redirect?
A 301 redirect is a permanent redirect of website traffic from one URL to another. 301 redirects send organic site traffic and other referral traffic to a different URL than the one they selected.
The simplest metaphor for a 301 redirect is if you were to move house, you might set up a postal redirect with the Post Office. The Post Office will take any post that is directed to you at one address and redirects it so that you are still the recipient but at the new address.
Much like your post, you still want to receive your website traffic and you do your best to tell all your family and friends that you have moved, but people don’t always update their address book and your old address will inevitably still get that Postcard from Barcelona or that thoughtful personalised Christmas Card.
A 301 redirect is key to maintaining your website’s domain authority, SEO strategy and those all-important Google rankings when the URL is changed for any reason. 301 redirects also link various URLs under one umbrella so search engines rank all of the addresses based on the domain authority from inbound links. A 301 redirect differs from other types of redirect as it is permanent, as opposed to, say, a 302 redirect which is temporary.
