## 404 NOT FOUND! Sorry, the article you are looking for was not found!! The 404 page is an essential part of any website, playing a crucial role in user experience and SEO optimization. A 404 error occurs when a user attempts to access a page that does not exist or has been deleted on the website. If the site owner fails to set up a custom 404 page, broken links will appear, making it difficult for search engine crawlers to index the site properly. ## Origin of the 404 Not Found Error It is said that before the third technological revolution, the internet was essentially a large central database located in room 404. At that time, all requests were manually processed by humans. If the requested file could not be found in the database or if the user entered an incorrect file number, they would receive a response: room 404 : file not found. After the internet emerged, people gradually adopted 404 as the standard error code indicating that a file was not found on the server. Of course, historical research confirms that room 404 never actually existed. ## Two Major Benefits of Setting Up a 404 Page * Guide users not to leave the website, enhancing user experience. * Prevent dead links from appearing on the site.
