301 Redirect

A 301 redirect is an HTTP response telling browsers and search engines that a requested URL has moved permanently to another address. It is useful when a service page changes its URL or a business moves to a new site structure. Someone following an old link can arrive at the relevant new page instead of hitting an error. A permanent redirect is also a signal to search engines about which URL should be treated as the destination, but it is not a promise that rankings will remain unchanged. Redirect old pages to closely matching replacements where they exist; redirecting unrelated pages to the homepage often creates a poor experience.
