## 404 NOT FOUND! Sorry, the article you are looking for was not found!! The 404 page is an essential part of any website, bearing the responsibility of user experience and SEO optimization. A 404 error typically occurs when a user accesses a page that does not exist or has been deleted on the website. If the site owner does not set up a custom 404 page, dead links will appear, making it difficult for search engine crawlers to index the site. ## Origin of 404 Not Found It is said that before the third scientific revolution, the internet was essentially a large central database located in room 404. At that time, all requests were manually processed. If the requested file could not be found in the database, or if the user made a typo in the 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 for "file not found" by the server. Of course, in reality, there is no such thing as room 404. ## Two Major Benefits of Setting Up a 404 Page * Guide users not to leave the site, enhancing user experience. * Prevent dead links from appearing on the website.
