What is a 404 Page?
A 404 page is the standard error message that is displayed when someone tries to access a web page that doesn't exist.
This can happen for any number of reasons such as the page may have been deleted, moved, or renamed and you have not set up a 301 redirect in its place.
When a 404 error occurs, the user will see a generic error message that says "404 Page Not Found".
The most common reason for seeing a 404 page is due to clicking on links that are outdated and no longer point to the correct page.
Other reasons include the web page they are trying to access no longer exists or they have simply typed in the wrong URL.
