404 NOT FOUND!

Sorry, we couldn't find the article you were looking for!!

The 404 page is an essential part of any website, carrying significant responsibility for user experience and SEO optimization. A 404 error occurs when users visit pages that do not exist or have been deleted from the site. If webmasters don’t set up a custom 404 page, dead links may appear, which can negatively impact search engine indexing during spider crawling.

Origin of 404 Not Found

Legend has it that before the Third Industrial Revolution, the internet was essentially 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 made an error in writing down the file number—the user would receive a message saying: room 404 : file not found. After the rise of the modern internet, people became accustomed to using 404 as the standard server response code indicating that a file could not be found. Of course, there is no actual historical evidence supporting the existence of such a legendary Room 404.

Two Major Benefits of Setting Up a Custom 404 Page

  • Guide users to stay on your site instead of closing it, enhancing their overall experience.
  • Prevent broken links from appearing throughout your website.
