404 NOT FOUND!

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

The 404 page is an essential part of any website, carrying the responsibility of user experience and SEO optimization. A 404 error occurs when users visit pages that don't exist or have been deleted on the site. If webmasters do not set up a 404 page, dead links will appear, which can negatively impact search engine indexing when crawlers access such URLs.

Origin of 404 Not Found

Legend has it that before the third technological 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, they would receive a return message: room 404 : file not found. After the rise of the internet, people became accustomed to using 404 as the server error code indicating that a file was not found. Of course, historical verification shows that the legendary Room 404 does not actually exist.

Two Major Benefits of Setting Up a 404 Page

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