404 NOT FOUND!
Sorry, the article you are looking for was not found!!
The 404 page is a must-have page for websites, bearing the responsibility of user experience and SEO optimization. The 404 error is typically returned by the server when users access a page that does not exist or has been deleted on the website. If the site administrator does not set up a 404 page, dead links will appear, which is unfavorable for search engine crawling and indexing.
Origin of the 404 Not Found Error
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, the user would receive a response message: room 404 : file not found. After the internet emerged, people gradually adopted 404 as the standard error code for server-not-found files. Of course, historical research confirms that room 404 never actually existed.
Two Major Benefits of Setting a 404 Page
- Guide users to stay on the website, enhancing user experience.
