A check server headers tool is a HTTP status codes checker which is used to make sure that your URL’s are coming back to the proper designated status code that is located in the server header. The main function of a check server header is to help obtain as much web exposure to your web site as possible. It is one of the technical phases involved in the ultimate optimization of your web site.

In order for your web site to be fully optimized, so that your web site is displayed higher in the search engine rankings, it is necessary for your URL to return to its assigned status in the server header. If it does not it will then become a problem for the verification of the URL and can result in an error in the coding. Now basically check server headers HTTP status codes are seven in number. They are not a total of seven but these are the most essential ones when we look at them for indexing and search engine marketing point of view.

Before you can put any of them to use, it is highly recommended that you first check that the URL you have for your web site is indeed returning to its designated status codes in the Server Header. One of the most useful ways in which a header checker is used is to test 301 redirects and it’s generally the most common method. There are a few interpretations that can give you a good idea of what to make of the server responses. If there is a note stating 200 OK, it means that your request was completed successfully and no problems took place during its execution. But the thing to remember is that the information that you will get as a response greatly depends on the method which was used to actually make the request. This has a major say in what the outcome of the request will be.

In the case of 301 Moved Permanently, it means that the requested resources has now been given a permanent new URL and all future references made to that resource should be made using the URL that has been newly designated. 302 Found, means that the requested resource has been temporarily moved .Now this would be to another location, and will not remain there permanently but will serve as a location for the time being. 400 Bad Request usually refers to a syntax error on the part of the programmer and as a result could not be understood by the server and hence could not execute the command.

So when typing a request, be sure you have written the command correctly in order to avoid error. 401 Unauthorized means that the request requires authentication and cannot be completed without proper authorization. 403 Forbidden is obviously when the server has found the required request but is then refusing to complete the task. This can be because of many reasons but most commonly due to security issues.
