301 – The page you were trying to get to has moved to a new location. The server should automatically redirect you to the new page and you shouldn’t have to do anything further. Search engine marketers use 301’s a lot when a page is removed or a new website is created so that visitors and search engines can find the new page easily.

403 – You are not authorized to view this page. Either you authenticated incorrectly or your IP address is restricted from viewing the page. In either case its back to the drawing board for you.

404 – The page you were trying to get to does not exist. It might have existed in the past and has been removed or the link you followed was just wrong. There is no redirect and you’ll have to find your page another way. Our creative team put together a great 404 page for our site that hopefully not many people get to see.

500 – Any 500 code probably means that something out of your hands has gone wrong. You might try back in a few minutes in case it’s a server load issue but if the issue doesn’t clear up you might try and let the manager of the website know that you had an issue. Try to remember what you did prior to the error because that can be helpful for troubleshooting.

301 - It is a permanent redirection to signify to the crawlers that your content has moved permanently
403 - The 403 Forbidden error is an HTTP status code which means that accessing the page or resource you were trying to reach is absolutely forbidden for some reason.
404 - It is a HTTP standard response code indicating that the client was able to communicate with a given server, but the server could not find what was requested.
500 - Internal Server Error is a generic error message, given when no more specific message is suitable. There are a number of causes for a 500 Internal Server Error to display in a web browser.

Nice information.

The 4xx class of status code is intended for cases in which the client seems to have erred. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition.

[Evelynraagmetss]

The HTTP status codes are divided into five diverse classes. There are specific implications for the HTTP Web Server Status Codes and Messages for example

301 is moved permanently
403 is forbidden
404 is not found
500 is internal server error
