A 301 redirect informs search engines that a website or page has been moved permanently. You should use an HTTP 301 when you're migrating a site or creating a new website. It’s also appropriate to use a 301 if you’re joining two websites together. 301 also works if you're making changes to the URL that are not intended to be reverted.
