Search engine error 404

• This is the standard message you may see when you visit a missing page or file. It is called an HTTP 404 Error because 404 is the HTTP status code the page should return to tell browsers or search engines that the requested URL refers to a web page or file that does not exist. A valid page or file should return a 200 status code.
