A 404 error is an HTTP status code that indicates the requested page does not exist and the server cannot locate it. In other words, the server can not find the webpage at the requested URL.
A 404 error occurs when the requested page has been removed from the server or the URL for the page has been changed. It can also happen when we mistype the URL.
User experience can be bad if a 404 error occurs, but we can customise the 404 error message with navigation or suggest some other page, so that users can be engaged.
Common Causes of 404 Error
- Requested resources have been deleted from the server.
- When users type the incorrect URL
- Broken links (Internal/external)
