404 Not Found client error response code indicates that the server can't find the requested resource. Links which lead to a 404 page are often called broken or dead links, and can be subject to link rot.
A 404 status code does not indicate whether the resource is temporarily or permanently missing. But if a resource is permanently removed, a
410 (Gone) should be used instead of a 404 status.

Custom error pages
Many web sites customize the look of a 404 page to be more helpful to the user and provide guidance on what to do next. Apache servers can be configured using an
.htaccess file and a code snippet like the following example.
ErrorDocument 404 /notfound.html
For an example of a custom 404 page, see MDN's 404 page.
Custom design is a good thing, in moderation. Feel free to make your 404 page humorous and human, but don't confuse your users.
