The 200 OK Status indicates that a resource (for example a webpage) was successfully located on a server. It’s a response provided in HTTP that quickly shows that the webpage requested has been found.
The 200 OK Status is not displayed to web users. Instead, it is sent behind the scenes in order to confirm that a web-file or webpage has been successfully located. While that message is relayed out of sight of the web user, the browser is able to receive the page and load it for the user, often in less than two seconds.
