Today we will talk about what features an error page should have and how we can implant the custom error page into our site or blog.

The Features of a Good 404 Error Page

The points that I will refer to have been working for me for a couple years.

1. Descriptive title – The user should know they are on a 404 page, so don’t forget to tell them they are.
2. Sitemap – If you have a sitemap, be sure to include a link to your sitemap on your error page. People might browse through the sitemap to find the page they were looking for.
3. Mistyped URL – On an error page you could include the mistyped URL. This makes it easy for the visitor to scan the URL for typos or mistakes.
4. Search box – A search box in the 404 page is a must. The possiblity exists that the information is still on the site and with a simple search, the user might find the information they need.
5. Common links – Adding a couple links to some common pages (like the about/contact/articles pages) will increase the number of people that stay and want to read something on your site.
6. Popular articles – Displaying a number of popular articles is good to push your best content forward. Visitors might get interested by these titles and click an article.
7. Archives – It is also possible to add the list of archives to your error page. They might find the article they are looking for. If not, they might browse the archives to look for this article and then might stumble on some other interesting article.

Implant the 404 Error Page in Your Site

Now you know what features your error page has, it is time to implant it on your site or blog. I will discuss two ways to get your error page up and running. One way is an error page in WordPress and the other is via .htaccess.

404 Error Page in WordPress

WordPress has a build-in error message in their themes. This isn’t the best solution as it only give the user this explanation: Error 404 – Not Found .

Editing the error text

One thing you can do is editing that text in your WordPress theme. You should locate index.php and find the error message. You can add more and better text to your likings.

Creating an error page

You could also create a custom error page. This solution is in my opinion the best for WordPress. You should make a file called 404.php, add the custom text and messages, add it in your theme directory and your error page is ready to go.

404 Error Page via htaccess

If you don’t use a blogging tool like WordPress you need a proper looking 404 error page too.

The first step we will take is opening (or creating if you don’t already have one) the .htaccess file. We need to add a couple extra lines to this file to tell our server to redirect the visitor to a custom 404 page once they have need it.

You should add these codes to the .htaccess file:

1

ErrorDocument 404 /404.html

This tells the server your 404 document is located somewhere other than default. You now have the power to change the error page to your likings.

Other Error Pages

You could also use this trick to build custom error messages for other apache errors. Take a look here for the status codes Apache uses.
