We say 404 pages, both for some reason, when the client requests a URL to the server side, the server cannot find the specified resource or the requested file does not exist, someone for the move, delete, etc., or some other non-human reason, resulting in the target page does not exist, the server will return an error page, usually: 404 Not Found. So when the user comes into your site and returns a mistake like this, will he stay on the current page? If it is a visitor for the first time, how much will it be? So we can make a 404 error page, place some navigation, search box, etc in this page, You can also modify the style of a 404 page. The goal is simply to tell the user that although your target page can't be opened for some reason, it's just as exciting as anything else.

Once a few friends chat to 404, the other can not help but be filled with emotion, said not why use the 404 page after the homepage on the search engine disappeared. I then compared the differences between the 404 pages, in the Internet to collect relevant information, and other webmaster to explore. The following two points require special attention in building 404 pages:

1, do not return 404 pages to the home page, such as other jump forms, usually this will only lead to your home page in the search engine in the hours.

2, do not use absolute address, such as: http://www.xxx.net/tool/alexa.asp, usually this return is 200 or 302 states.

Here is the difference between these states, the correct 404 page return should be 404 states, and some 404 pages return 200, 302 status. When a spider accesses a nonexistent page, it returns a 404 state, and the search engine determines that the page is invalidated and is cleared from the database. And when the search engine returned to the 200 state, it is normal, he will think that the link is normal and effective, it may lead to multiple URL address with the same page, it may also lead to a reduction in the weight of the search engine.
