A 301 redirect is an HTTP status code that serves as a mechanism for permanent redirection from one URL to another. In other words, if your visitor goes to the address for page A, it’ll send them to page B.
Furthermore, it’ll group different URLs together for search engine optimization purposes. So, in this example, hits for both addresses (A and B) will contribute to a common domain authority score. Check out Moz’s helpful article for more information about domain authority.
