404 NOT FOUND!

Sorry, the article you need was not found!!

The 404 page is an essential page for a website. It carries the responsibility of user experience and SEO optimization. The 404 page usually appears when a user visits a page that does not exist or has been deleted, and the server returns a 404 error. If the webmaster does not set a 404 page, dead links will appear. When spiders crawl such URLs, it is not conducive to search engine indexing.

Origin of 404 Not Found

It is said that before the third technological revolution, the form of the Internet was a large central database, and this database was set up in room 404. At that time, all requests were made manually. If the file requested by the requester was not found in the database, or if the requester wrote the wrong file number, the user would receive a return message: room 404: file not found. Later, after the Internet rose, people became accustomed to using 404 as the error code for server file not found. Of course, the legendary room 404 in reality does not exist.

Two Major Benefits of Setting Up a 404 Page

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