HTTP 301 Moved Permanently — What It Means

What HTTP status code 301 Moved Permanently means, when servers return it, and how to handle it correctly.

Published September 22, 2026

HTTP 301 Moved Permanently — The requested resource has been permanently moved to a new URL.

Key points

  • Search engines transfer SEO ranking signals to the new URL over time
  • Browsers and caches may cache this redirect indefinitely
  • Some older clients incorrectly changed POST to GET on a 301 — 308 exists to remove that ambiguity
