The HTML response codes are very important to identify the wrongs in a particular webpage and for the convenience of website SEO.
Server Error Responses
500 Internal Server Error
The server has encountered a situation it does not know how to handle.
501 Not Implemented
The request method is not supported by the server and cannot be handled. The only methods that servers are required to support (and therefore that must not return this code) are GET and HEAD.
502 Bad Gateway
This error response means that the server, while working as a gateway to get a response needed to handle the request, got an invalid response.
503 Service Unavailable
The server is not ready to handle the request. Common causes are a server that is down for maintenance or that is overloaded. Note that together with this response, a user-friendly page explaining the problem should be sent. This response should be used for temporary conditions and the Retry-After HTTP header should, if possible, contain the estimated time before the recovery of the service. The webmaster must also take care about the caching-related headers that are sent along with this response, as these temporary condition responses should usually not be cached.
504 Gateway Timeout
This error response is given when the server is acting as a gateway and cannot get a response in time.
505 HTTP Version Not Supported
The HTTP version used in the request is not supported by the server.
506 Variant Also Negotiates
The server has an internal configuration error: the chosen variant resource is configured to engage in transparent content negotiation itself, and is therefore not a proper end point in the negotiation process.
507 Insufficient Storage (WebDAV)
The method could not be performed on the resource because the server is unable to store the representation needed to successfully complete the request.
508 Loop Detected (WebDAV)
The server detected an infinite loop while processing the request.
510 Not Extended
Further extensions to the request are required for the server to fulfill it.
511 Network Authentication Required
Indicates that the client needs to authenticate to gain network access.

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.
Well done. keep writing
