A 404 Error or 404 Error Not Found message is triggered when a web page has been disabled, moved to another URL or never existed and the URL has been entered incorrectly. A 404 Error or ‘dead link’ are notoriously bad for user experience and can lead to high bounce rates and frustrated users exiting websites. Many website owners don’t make regular checks of their external links or backlinks either, which could be leading users to 404 Errors. 301 redirects combat 404 Errors by redirecting a user to the correct new page.
