3XX Redirect HTTP Website Codes

301 Permanent Redirect

A 301 indicates a permanent redirect from one URL to another, which means that any users who visit the old URL will be automatically redirected to the new URL. When a page has been permanently relocated or removed from a website, a 301 redirect transfers all ranking power from the old URL to the new URL.

302 Found

The 302 Found redirect status response code indicates that the requested resource has been temporarily redirected to the URL specified in the Location header. SEO-wise, 302 should just be used when making temporary redirects, as it does not pass any link equity the same way as 301.

303 See Other

A 303 See Other error indicates that the URL you’re trying to reach is redirecting you to another URL.

The appearance of a 303 See Other is very uncommon and is not something that will require much user intervention. Modern browsers tend to automatically detect the 303 See Other response code and process the redirection action to the new URI automatically. The response sent by the server to the client will also include a special Location header, that indicates the new URI where the requested resource can be found. This informs the browser that the POST request data was received by the server, but the server does not believe the requested resource is of what the client is requesting, so it includes a more representative resource on the response.

304 Not Modified

A 304 Not Modified message is an HTTP response status code that indicates that the requested resource has not changed since the previous transmission and that the client does not need to receive it again. A 304 Not Modified response code effectively functions as an implicit redirect to a cached version of the requested resource.

Suggested solutions:

  1. Clear browser
  2. Run cleaners to remove potential malware and viruses on your browser.
  3. Disable browser extensions

307 Temporary Redirect

A 307 Temporary Redirect is an HTTP response status code that indicates that the user’s requested URL has been temporarily moved and will be returned soon.

Both the 303 and 307 codes indicate that the requested URL has been temporarily moved, and in relation to 303, 307 was sent by the server after the new URI included in the 303 response is ignored by the user.

308 Moved Permanently

The 308 Permanent Redirect redirect status response code indicates that the requested resource has been moved permanently to the URL specified in the Location headers.
