What is a "ghost page"?

@kyleigh.wolff 

A "ghost page" is a term used to describe a web page that can be accessed by a URL (Uniform Resource Locator) but does not contain any content or does not return any content to the user. This can occur for a number of reasons, such as a broken link, a misconfigured server, or a page that was removed or deleted from a website.

In some cases, ghost pages can be created intentionally, for example as a placeholder for a page that is under construction or to preserve a URL for a page that has been moved or renamed. In other cases, ghost pages can be a result of technical issues or errors and can cause confusion for users who expect to see content at that URL.
