The 404 error occurs when the web server is running, but the specific URL cannot be located. Here are some common reasons why it may occur:
- The URL is misspelled or malformed.
- The link that has been followed is broken or outdated, and the web page it points to has been removed.
- The webpage has been moved without redirecting the original URL to the new location.
- The web page has been deleted and is not available on the server.
Impact of Error 404 on User Experience and SEO
Error 404 can be frustrating for users searching for specific content, which can hurt the user experience (UX). This frustration can lead users to leave the web, which in turn can negatively impact bounce rates and conversions.
From an SEO perspective, a lot of 404 errors can be viewed negatively by search engines, especially if broken links come from other pages within the site itself. This can result in a penalty in search engine rankings.
