We’ve all been there: you click a link with high hopes, only to land on a lifeless, uninspiring “404 – Page Not Found” message. It’s frustrating, and for business owners, it’s a missed opportunity. But here’s the thing: your 404 page doesn’t have to be a dead end. With a little creativity and a few tweaks, you can transform this page into a useful tool that engages visitors and keeps them exploring your site.
As someone who works with mission-driven, service-based businesses, I understand the importance of every interaction your audience has with your website. Even when something goes wrong—like a broken link or a mistyped URL—you have the chance to show your audience that you care about their experience.
In this blog, I’ll show you how to create a custom 404 page on WordPress, explain why it’s worth your time, and offer practical steps to get it done. Let’s make that error message work for you instead of against you.

It’s actually really easy to set up a custom 404 page on WordPress too.
What is a 404 page?
If someone clicks on a link to your site to a page that doesn’t exist any more they’ll be redirected to a 404 error page. Usually the page will display a message along the lines Page not Found with a search box for you to search the site for what you’re looking for.
404 is the http error code that means a page couldn’t be found. I’m not going to go into any more detail on http codes here, because even for me they’re boring, and you don’t need to know too much about them.
Why Does a Custom 404 Page Matter?
You might be thinking, “Why bother customizing a 404 page? Most people won’t even see it, Kim.”
Hopefully this page won’t be a top destination, but it plays a critical role in your website’s overall experience. When someone does land on your 404 page, they’re already at a bit of a crossroads. They’re either going to leave your site, frustrated and unimpressed, or they’ll stay, find what they need, and maybe even become a client.
A custom 404 page can help tip the scales in your favor. Here’s why it’s worth creating one:
- It Improves User Experience
A generic 404 page doesn’t give your visitors any direction, leaving them to figure out their next steps—or worse, encouraging them to leave. A custom page, on the other hand, can gently nudge them towards the content they need, or the content you want to send them to, making the experience much smoother and more enjoyable. - It Boosts Your Brand
Every part of your website is a chance to show off your brand’s personality, and your 404 page is no exception. Whether you use humour, empathy, or a professional tone, this page can reinforce your brand values and make a lasting impression. - It Keeps Visitors on Your Site
By offering links to popular pages, a search bar, or even a contact form, you give visitors reasons to stay instead of bouncing away. And you can direct them towards the website goals you have for them. This is especially important for mission-driven businesses that rely on building trust and connection with their audience. - It Supports Your SEO Efforts
404 errors themselves don’t directly harm SEO but a poorly designed 404 page can lead to higher bounce rates, which may impact your site’s performance in search results. A custom page helps minimize this by providing clear paths for visitors to follow and a reason for them to stay. - It Shows You Care
A thoughtfully designed 404 page sends the message that you’ve considered their needs, even in unexpected situations. It’s a small thing, but it can make a big difference in how people see your business.

How to set up a custom 404 page on WordPress
Now that you’re convinced of the benefits, let’s get into the how-to. Creating a custom 404 page on WordPress can be as simple or as advanced as you like, depending on your comfort level with WordPress and your design preferences. I’ll walk you through a few different approaches.
Using a Plugin
On my demo site I downloaded the 404Page plugin. I literally just searched 404 and installed the one with the most active users with the highest rating and this was it. I’m stabbing in the dark a bit right now, I installed it as I was writing this post.
- Go to your add plugins page and search 404. Like I said above, I used 404Page, but I reckon most plugins will work in a similar way.
- Hover over the Appearance menu on the left hand side of the screen and click on 404 Error Page. In the dropdown list choose the page that you want to be displayed when a 404 error happens and click save.
- To test it, navigate to a page on your site that you know isn’t there. I used demo.thebloggenie.com/abc in this example
Adding a Custom 404 page on WordPress without a plugin
If you’d rather not use a plugin you can change your theme’s 404.php file instead. I’ll be honest, depending on your theme it’s probably going to be quicker and easier for you to use a plugin. You’re more likely to be able to make a professional looking page that fits in with the rest of your site doing it your usual way.
*** Before I go any further, I want to stress that you should only choose this method if you’re using a child theme (if you’re not you should be, but that’s a lesson for another day). Also make sure that you take a backup of your site before you start making changes to any files manually.
Here’s a tutorial on how to create a WordPress child theme. ***
Changing your theme’s 404.php file is really easy if you know a bit of HTML.
- Hover over the appearance menu and click on Editor.
- Choose your active theme from the dropdown list on the top right, then scroll through the list of files to find the 404.php file. It should look something a bit like this, depending on your theme.
- Start making changes. I’m going to make some basic changes just to show you how, what you do with it then is limited only by your imagination and HTML/CSS skills.
- To test it, navigate to a page on your site that you know isn’t there. I used demo.thebloggenie.com/abc in this example
How to Set Up a Custom 404 Page on WordPress
So there you have it, that’s all there is to setting up a custom 404 page on your WordPress website. It’s a really simple thing to do but could make a big difference in helping keep people on your blog. The great thing about it is that you can change it up to match your current blog focus. For example if you’re pushing your email list put an opt-in form on your 404 page. Looking to get more people into your facebook group? Put a link and some quotes from current members on your 404 page.
No-one ever wants their readers to get a 404 error, but at least this way, you can use it to your advantage when it does happen.
