Error 404 means in web search?

Yes, in web terms, "Error 404" means:

"Not Found" — The server could not find the requested webpage.

It usually happens when:

• The URL is typed incorrectly,

• The page has been deleted or moved,

• Or the link is broken.

It tells the browser that the server is reachable, but the specific page requested doesn’t exist at that location.
