404 NOT FOUND!

Sorry, we couldn't find the article you need!!

The 404 page is an essential part of any website, carrying significant responsibility for user experience and SEO optimization. A 404 error occurs when a user tries to access a page that does not exist or has been deleted on the server. If the site owner doesn't set up a custom 404 page, dead links may appear, which can negatively affect search engine indexing during web crawls.

Origin of 404 Not Found

Legend says that before the Third Industrial Revolution, the form of the Internet was one large central database located in Room 404. At that time, all requests were manually processed by humans. If the requested file wasn't found in the database—or if the requester had written down the wrong file number—the user would receive a return message: room 404 : file not found. After the rise of the modern Internet, people became accustomed to using 404 as the standard error code indicating that the server could not locate the requested file. Of course, historical verification shows that the legendary Room 404 never actually existed.

Two Major Benefits of Setting Up a 404 Page

  • Guide users not to close the website, enhancing user experience.
  • Prevent the appearance of broken/dead links on your site.
