404 NOT FOUND!

Sorry, the article you need was not found!!

The 404 page is an essential part of any website, carrying the heavy responsibility of user experience and SEO optimization. A 404 page usually appears when a user visits a non-existent or deleted page on the site, and the server returns a 404 error. If the webmaster does not set up a 404 page, dead links will appear, which is detrimental to search engine indexing when crawlers access such URLs.

Origin of 404 Not Found

Legend has it that before the Third Industrial Revolution, the form of the Internet was a large central database located in Room 404. At that time, all requests were completed manually. If the requested file could not be found in the database or due to incorrect numbering by the requester, users would receive a return message: room 404 : file not found. After the rise of the Internet, people became accustomed to using 404 as the error code for files not found on the server. Of course, actual verification shows that the legendary Room 404 does not exist.

Two Major Benefits of Setting Up a 404 Page

  • Guide users not to close the website, enhancing user experience.
  • Prevent the website from having dead links.
