The 404 page is the page that is returned when the user enters the wrong link. The purpose of the 404 page is to tell the viewer that the requested page does not exist or link incorrectly, and that the user is directed to use other pages of the site instead of closing the window to leave.

404 Impact on SEO

Customizing the 404 error page is a good way to enhance the user experience, but it often fails to notice the impact on the search engine, such as a bad server-side configuration that causes the return of a "200" status code or a custom 404 error page to use meta-refresh to return a "302" status code. A custom 404 error page that is correctly set should not only be displayed correctly, but should also return the "404" error code instead of "200" or "302". Although the HTTP status code is "404" or "200" for the user, it is very important for the search engine.

Search engine spider when request a URL to get "404" state response, that means that the URL is no longer indexed and the page is deleted from the index database by feedback to the datacenter, although the deletion process may take a long time; when the search engine gets "200" Status code, the URL is considered valid and will be indexed and included in the index database, so that the two different URLs have exactly the same content: Customize the contents of the 404 error page, which causes the replication Web page problem. Light is the search engine down the right, heavy will k off the site.

How to achieve a good 404 page

Change the server default error page to achieve results. Here are some suggestions for making it easy for visitors to make regular visits.

Follow the philosophy:

Provide concise problem descriptions to eliminate visitor frustration.

Provide a reasonable solution to assist visitors to achieve the goal of the visit.

Provides a personalized and user-friendly interface to enhance the access experience.

How to implement (in order from simple to complex):

Make the visitor go somewhere rather than back.

A page contains links to important parts of the site, such as a home page or site map. Don't just tell them to check spelling. Use text links instead of pictures because many visitors will not think of clicking on this picture.

Example: Our site has a return link to the homepage. This is the minimum to achieve friendly feedback.

In addition, we will consider how to make up for the error through the feedback of the visitors when the effective help information is insufficient. You need to include an email link to the webmaster, or a form to submit a missing link. Visitors prefer to use the submit form relative to sending email. Add a search box to search the site. Lists links to pages that are close to the visitors ' expectations in the site to speculate on the pages the visitor is looking for. You do not need to adopt all of the above suggestions, but these recommendations serve the purpose of making visitors more likely to stay on your site. A reasonable 404 error page can be completed at this point, which will provide a lot of valuable information to visitors.
