HTTP Status Codes and Search Engines
Server Status code are the number values of the HTTP request. It is important to understand the different server status code that will be useful in the SEO perspective and how search engines bots react to the same.
Before getting into the server status codes it is important to understand the difference between HTTP /1.0 and HTTP/ 1.1 protocols. The HTTP/1.0 protocol has been stunningly successful and as a measure of its popularity, HTTP accounted for about 75% of Internet backbone traffic. In spite of its success, however, HTTP/1.0 is widely understood to have numerous flaws. To overcome the flaws in HTTP/1.0 the HTTP-Working Group (HTTP-WG) developed an improved protocol, known as HTTP/1.1. This specification states the various requirements for clients, proxies, servers and later became an Internet Engineering Task Force (IETF) Draft Standard. The server status code tends to differ based on the version of the HTTP.
Custom 404 Page and Search Engines
The 404 or Page Not found error message is a standard server response indicating that the server could not find the requested document by the client. The page that you overwrite the default 404 page with your desired content is a custom 404 page.
