The 404 error page was originally set by IIS or Apache as the default state, and when the search engine accesses the site error page, it returns a 404 status code that does not exist when the user accesses the page (the form of the 404 code). And when some sites because of the site's revision, resource integration and so on, resulting in many old URLs are deleted, and users, or other sites listed on these URLs are not updated in time. This causes users to access these invalid URLs when they are directed to 404 pages, and typically users are usually directly clicked on the Little Red Fork in the upper-right corner of the page to handle. In this case, many webmasters choose to customize the 404 error page to do their best to guide these traffic to the corresponding page, or home page, or inner pages. Originally this did not have any problem, but everything has double-sided, when you get these traffic, do you notice that your site in the search engine included significantly reduced, some keywords even dropped the phenomenon of ranking?

The 404 error is that the file or directory was not found by the server in response to a request from the client: The Web site cannot be accessed on the requested port.

When the search engine detects a site's error URL, if the return is not a 404 status code, but 200 status code, then he would think that the actual nonexistent page exists. So when a lot of wrong URLs are detected by the search engine, the same is returned to the 200 status code, is also considered as a Web page, so that the search engine that has a large number of duplicate pages. Obviously, it's easy to go to the site to collect the number of drops or even fall right.

No matter how you customize the 404 error page, the first important thing is to ensure that the search engine returns a 404 status code.

When you write a custom 404 error page, don't rush to see the gorgeous effect. First, check your custom 404 error page to return 404 status Code or 200 status code. This URL if also valid words can detect http://www.seobox.org/getheader.htm can also refer to the www.wanseo.com error page.
