The Ultimate Essential Guidelines for WordPress 404 Error Pages

Essential Guidelines for WordPress 404 Error Pages

WordPress is a popular blogging platform with its ease of use and development by many experts on the web in the way of themes, plugins, and many more features that we can use for free or under a commercial license. WordPress work-flow basically is about storing the blog’s content data to the database and then retrieving it with PHP and finally displaying it to the visitors. However, if the contents that we’re trying to retrieve no longer exist in the database, as a result there would be a 404 error page.

WordPress 404 Error Pages

You can imagine how frustrating it can be when you have clicked on a link from an article page or from a search result on Google, you’re in a bit of a hurry and want to see the content, but the page you’re waiting for couldn’t be found! Disaster! How can this be happening? We will discuss this in this article.

Overview 404 Error Pages

Error 404 is a standard HTTP (HyperText Transfer Protocol) status code. The “Not Found” respond code, shows that a client (browser) isn’t able to make contact with a server, this happens because the server can’t complete the request made by the client, or the browser configuration wasn’t properly setup to fulfill the request.

The 404 “Page Not Found” failure message is an error page which is displayed each time a client/browser requests an unavailable page from a website. How could this be unavailable? Below are the common factors causing the visitor to reach the 404 error page on a website:

  • The Wrong Address Link: Often caused by typing errors or truncations.
  • The Lost Page: Possibly it happened because the site’s content had been deleted or it’s in a reconstruction progress.
  • The Contents Blocked (Private/Restricted Pages): The filtering system of a server is also capable of returning an HTTP 404 response when users are trying to access a blocked content through a browser.

How to Deal With 404 Error Pages

For some visitors, it is quite annoying to be faced with a 404 error page from a website that fails to display the content they wish to view. They will usually assume that the content is no longer available on the website as it may have been deleted by the owner. If they think this, they will move onto what they consider to be more reliable sites. But what if the content has just had the address/URL redirected?

Of course, it’s a loss for the visitor and especially the site owner as he/she is losing traffic from their site, disappointing visitors by displaying a content error. Below are some tips to help site owners to keep their visitors on their site longer.

PHP Redirect

If your 404 error page is formatted in PHP, then this PHP redirection method will be very effective, because it’s supported by all browsers on the web. These are the sample codes:

header ("Location: url");

JavaScript Redirect

Below is the sample codes for JavaScript to redirect visitors to the pages which you think will attract their attention. These are the sample codes:

<script type="text/javascript">
<!-- window.location = http://your_url_name/ //-->

That will lead to this:

<a href=”http://your_url_name/”>click here if you’re not redirected automatically.</a>

The purpose of “Click here if you’re not redirected automatically.” message is solely to alert the visitors when they’re not activating the JavaScript function on their browser.

Redirect with a .htaccess / htaccess.txt

This is a good choice, because the effect would globally touch the sub-domain that you own. This is the line which should be added to your .htaccess/htaccess.txt file:

ErrorDocument 404 error/http://www.yourwebsite/

So, we have at least 3 ways above that we can use for handling 404 error page. But generally it’s been automatically configured for a website/blog which is based on Content Management System like WordPress. In addition, we just have to add one from the two codes above (JavaScript or PHP) onto its 404 default.

Or perhaps you intend to make your own error page for your site, this can also be done. Below are the sample instances in PHP:

/* Error page: ErrorPage.php */
<head><title>404 Error Page</title></head>
<h1>Error 404</h1><br>Sorry, Page Not Found.
$ip = getenv ("REMOTE_ADDR");
$requri = getenv ("REQUEST_URI");
$servname = getenv ("SERVER_NAME");
$combine = $ip . "tried to load" . $servname . $requri;
$httpref = getenv ("HTTP_REFERER");
$httpagent = getenv ("HTTP_USER_AGENT");
$today = date("D M j Y g:i:s a T");
$note = "Sorry, nothing here!";
$message = "$today <br>\n
$combine <br> \n
User Agent = $httpagent \n
<h2> $note </h2>\n
<br> $httpref ";
$message2 = "$today \n
$combine \n
User Agent = $httpagent \n
$note \n
$httpref ";
$to = ""; \\ change to your email address
$subject = "Error Page from Your Site"; \\ change email subject
$from = "From:\r\n";

mail($to, $subject, $message2, $from);
echo $message;

Visit our <a href="">Home Page</a>


Done. You can now refer users to 404 error message substitutes on your website. Further, it will send an email to you automatically when visitors reach a 404 error page on your website, so they no longer need to report to you by email. Yes, just like that! You can copy and put it on the server. Remember you have to configure your .htaccess file on the server by adding the line below that will refer to your error page file, here is the code:

ErrorDocument 404 error/ErrorPage.php

When you’re finished with the codes, you can now try it.

Tips In Designing 404 Error Pages Effectively

Sometimes it looks poor showing the standard design of 404 error pages. There are some points to consider in designing a 404 error page for your website.

Tips in Designing 404 Error Pages Effectively

Tell Them It’s Not Found (Lost/Missed/Anything!)

It’s obvious that you have to impart this message to your visitors so they’ll understand that the content/information they’re searching for isn’t available on the website. You can say it in brief, like “We’re sorry, the page is not available” or maybe like this “OMG, how could this happen? This is embarrassing”. Try other words that you think suit your visitors style/taste. And remember, do not use sentences that impose the blame on your visitors.

Display the Main Menu

Yes, it’s correct to display the main menu, so that visitors have more access to the contents on your website, not just a link that refers them only to your homepage. Thus, the visitors exploring passion would spread to the various topics of contents or categories.

Combine With The Available Content

If you think that with offering other content to visitors on your website is pretty catchy, then go for it! Try to combine with actual content that you have. It could be a popular article on your website, featured content or archived content that you have on your site? You’re free with your ideas, the point is to make the visitors interested for as long as possible in your website.

Use Your Site’s Theme Design

I’m sure you don’t like to see your 404 error page appear in plain and unformatted design like the other sites. By using the theme design of your site, your 404 error page will look much more creative and user friendly with your logo, color scheme, perhaps cartoon characters that you like and many more ideas you can use to make your visitors no longer feel in exile when they couldn’t find what they were searching for on your website. They can immediately refer to what you’ve offered them in point 2 and 3 above.

Show The Search Box!

This last point shouldn’t be an option, you should have a search box on your 404 error page. The reason is if the visitor isn’t interested in point 2 and 3 you’ve offered above, they could still do a content search, based on the topics they’re interested in on your site. This will make visitors feel more at liberty to explore your site and you as the site owner will also get benefits from gaining traffic to the content that is found by visitors through this search box facility.

Yes, these should be the things to consider when you’re designing your 404 error page effectively to hold the attention of your visitors when they can’t find something on your site. You can also configure your 404 error page to send you an email automatically when your visitors reach it on your site.

Examples of Error 404 Pages

Below is a list of links to 404 error messages from various sites with creative graphics and taste. Perhaps you can learn something from these, or are there any other elements that you think are worth adding to make it even more attractive? I think this has its own value to your visitors that you are taking care of your website neatly and with attention to detail.

Here are some WordPress plugins that will help you to manage, monitor and customize your 404 error page more efficiently, so your visitors don’t need to leave your site right away.

It all depends on you where you want to redirect your visitors when they reach the 404 error page on your website. Many sites redirect visitors to their homepage, there are also some sites that redirect visitors to the membership registration page of their website, or maybe you have other ideas?

There are also some sites which creatively place a pre-direct as an advertisement page along with a message to the content page that they are referring the visitor to. Thereby, the ad revenue will be increased through this 404 page. If you want to, you could also increase your other website traffic, by redirecting the visitors to your other website where you want the traffic to be increased. But I don’t recommend this idea, these are only examples of ways that we can be seen on the web. Apart from ethical considerations and other things, the potential traffic we can obtain from 404 error pages is pretty fair, more so for the newly CMS migrated, or in progress of reconstruction websites.

And now it’s time for you to share what you know about 404 error pages, or tell us what you have done differently or maybe you have seen a different, inspiring, funny or pleasing page. Please feel free to let us know, don’t hesitate to leave your comments.

    It’s all about NOT using a 404 page and trying to help the user in their journey, because not matter how good the 404 page is, the user’s still not seeing what they want, and it’s quite simple to get around this when you know how.

    Feedback very welcome from you Bima and everyone else.

      Nice info. However I think 404 should never happen in the first place and we have over emphasized on it. Why not just direct all 404 back to the homepage?

    this is a sorely neglected part of webmastering. Never ceases to amaze me how many of our sites ignore their 404s. We recently found and started using for handling 404s across all our sites in a single interface. Very slick tool.
