What Are HTTP Status Codes?

HTTP status codes are three-digit responses sent from a web server to a browser, indicating the status of a request. They help determine if the request was successful, redirected or failed. For search engines these codes provide essential signals during crawling and indexing.

  2. 2xx: Success – The request was completed successfully.
  3. 3xx: Redirection – The requested resource has been moved or redirected.
  4. 4xx: Client Errors – The request was invalid or could not be fulfilled.
  5. 5xx: Server Errors – The server failed to process a valid request.
