HTTP Response Codes - Redirection Message Responses Status Codes​

The HTML response codes are very important to identify the wrongs in a particular webpage and for the convenience of website SEO. 

Redirection Message Responses

300 Multiple Choices

The request has more than one possible response. The user agent or user should choose one of them. (There is no standardized way of choosing one of the responses, but HTML links to the possibilities are recommended so the user can pick.)

301 Moved Permanently

The URL of the requested resource has been changed permanently. The new URL is given in the response.

302 Found

This response code means that the URI of requested resource has been changed temporarily. Further changes in the URI might be made in the future. Therefore, this same URI should be used by the client in future requests.

303 See Other

The server sent this response to direct the client to get the requested resource at another URI with a GET request.

304 Not Modified

This is used for caching purposes. It tells the client that the response has not been modified, so the client can continue to use the same cached version of the response.

305 Use Proxy Deprecated

Defined in a previous version of the HTTP specification to indicate that a requested response must be accessed by a proxy. It has been deprecated due to security concerns regarding in-band configuration of a proxy.

306 unused

This response code is no longer used; it is just reserved. It was used in a previous version of the HTTP/1.1 specification.

307 Temporary Redirect

The server sends this response to direct the client to get the requested resource at another URI with same method that was used in the prior request. This has the same semantics as the 302 Found HTTP response code, with the exception that the user agent must not change the HTTP method used: if a POST was used in the first request, a POST must be used in the second request.

308 Permanent Redirect

This means that the resource is now permanently located at another URI, specified by the Location: HTTP Response header. This has the same semantics as the 301 Moved Permanently HTTP response code, with the exception that the user agent must not change the HTTP method used: if a POST was used in the first request, a POST must be used in the second request.

The importance of knowing the particular HTML codes returned always come in handy when working with a website. SEO specialists will have to work with the website designers to position the required codes accordingly to notice the audience as well as spiders and bots of the Google crawler, about the condition of the target URL. For example the 301 HTTP response code is used to redirect a web page. It says to the Google crawler that, “This page is currently not here. Please find the link in the HTML response code to find out our new place”. This will redirect the traffic seamlessly to the new URL.
