301 Redirect

A 301 redirect is a permanent redirect which notifies the search engine that a certain link has been permanently moved to other URL. In most instances, the 301 redirect is the best method for implementing redirects on a website. Serving a 301 indicates to both browsers and search engine bots that the page has moved permanently. Search engines interpret this to mean that not only has the page changed location, but that the content—or an updated version of it—can be found at the new URL.
