Warning3xx redirection

Overview

The HTTP 301 Moved Permanently status code indicates the requested resource has been permanently moved to a new URL, and all future requests should use the new URL.

Key Details

  • This is the most important redirect status code for SEO, as it passes link equity to the new URL.
  • Search engines will update their index to replace the old URL with the new one.
  • Browsers and clients should cache this redirect and not request the old URL again.
  • The new URL is specified in the Location header.
  • A 301 may change the request method from POST to GET in some clients.

Common Causes

  • A website changed its URL structure or moved to a new domain.
  • A page was renamed or reorganized in a site restructure.
  • HTTP to HTTPS migration using permanent redirects.
  • A vanity URL or shortened URL pointing to the canonical location.

Steps

  1. 1Check the Location header for the new URL of the resource.
  2. 2Update bookmarks, links, and references to use the new URL.
  3. 3For SEO, ensure all old URLs have 301 redirects to their new equivalents.
  4. 4Verify redirect chains are not too long (ideally no more than one hop).
  5. 5Update internal links to point directly to the new URL.
