According to Google's Chinese website administrator blog
Reports,
GoogleAdded an "enhanced 404 page" tool in its website administrator tool to log on
Google website administratorClick "Tools"-"enhanced 404 page" to obtain the relevant code.
404 a webpage is displayed when a user attempts to access a webpage that does not exist on the website (because the user clicks a damaged link, the webpage has been deleted, or the user has entered an incorrect URL. The web page 404 is called because the network server returns the 404 HTTP status code, indicating that the web page is not found.
Generally, you 'd better create a custom 404 web page to obtain this part of user traffic. A good custom 404 web page can help users find the required information, provide other practical content, and attract users to further browse your website.
The 404 page tool provided by Google provides a Smart Search box and the most relevant link address when a page error occurs. This tool provides Javascript-based Web pages. When a 404 error occurs, Google will list a content on the web page and other addresses most relevant to the "missing" web page, and provides a Google-based intra-site search box.
According to my tests on this tool, Google found that the 404 tool currently does not support Chinese (although Google claims to support Chinese ), the generated 404 page prompts that the language is all in English. I hope Google can fix this problem as soon as possible.
