The 404 page is an informational page that appears when the user tries to visit a URL that does not exist.

This often happens when a page has been deleted or the address has changed.

The 404 page informs the visitor that the page was not found, giving them the opportunity to return to the home page or search for other content.

For example, if someone tries to visit ” example.com/old-page” and it does not exist, they will see a 404 page.

This page may also contain links to direct the user to other pages on the site.
