How To Customize Your WordPress 404 Error Page
When visitors try to access a page on your site that doesn’t exist, WordPress automatically displays something called a “404” error page.
The “404” error page (also know as a ‘page not found’ error) lets visitors know that whatever they were looking for can’t be found at that URL location.
Addressing 404 errors will not only make a difference to how visitors and search engines perceive your site, but it can also help you recover what would otherwise be lost opportunities to keep visitors longer on your site and potentially turn these into prospects, leads, or new customers.
For example, adding links to your error page pointing visitors to useful pages on your website will improve user experience, increase visitor retention rates, and decrease bounce rates on your site.
In this tutorial we’ll show you some of the ways you can customize your default WordPress 404 page to provide visitors with a better experience if they land on a wrong page and don’t find what they were expecting to see.
Where Is My WordPress 404 Page?
If you are not familiar with 404 error pages, you can see what your own site’s 404 page looks like (or even check to see if you have one), by typing a URL into your internet browser for a page that you know doesn’t exist on your site (e.g.mysite.com/adfgegrgertgrf) …
(404 error page)
WordPress is set to automatically look for the file 404.php when an error 404 is reached. A basic error 404 page is included with the default WordPress theme, but may be missing from some themes. If this file is not present, then it will display a basic error message like the example shown below …
(Error 404: Page Not Found)
Page Not Found Error – Your Options
There are a number of things that can lead to a “404” or “Page Not Found” error:
- Your post or page has been deleted or moved to another location
- Changes have been made to your permalinks or your page slug
- Changes have been made to a post category or category slug
- Code in your index.php or search.php files has been modified, resulting in invalid addresses being returned
- Web server files (e.g. “mod_rewrite”) have not been installed or are missing. Tip: If you are trying to use Pretty Permalinks (Search-Engine Friendly URLs) and you are getting errors, check with your webhost that mod_rewrite has been installed and is working correctly.
- You have published or promoted a wrong link (e.g. a link containing a misspelling)
- Your visitor has simply typed the wrong URL into their browser
Whatever the reason for getting a “404” error page may be, it’s important to acknowledge that your visitor has made an effort to come to your site and that they are probably going to be left feeling slightly confused or disappointed after arriving on your site and not finding what they expected to see.
So … what are your options when this happens?
You could just do what most people do and ignore the errors, but this will not create a positive outcome for either your visitor (disappointment) or for you (loss of opportunity). If a visitor follows a link to your site and is presented with a 404 page instead of the content they were looking for, it’s highly unlikely that they will search your site to find it. Most likely, they will simply assume that the content no longer exists on your site, and simply look elsewhere.
Additionally, ignoring your “page not found” issues can affect a search engine’s ability to index your site’s pages and impact the bounce rate on your site.
This can lead to poor search engine rankings. One or two 404 errors may not present much of a problem, but if your site is filled with 404 errors, it’s possible that your site will be penalized for having too many invalid links, and this can affect your rankings in the search engines …
(Too many page errors can affect your SEO)
If you choose to do nothing, then at least know that, depending on your theme, WordPress will automatically serve up a “404” page, and this page may include the option of allowing your visitors to search for content on your site …
(Some 404 pages allow visitors to search your site)
If anything, this is better than giving your visitors no option but to click the “back” button on their browser, leave your site and go somewhere else.
Another option is to automatically send all visitors to your home page or another page on your site using a redirect script or plugin when a bad URL is detected. From a visitor’s point of view, however, this may not be very useful or helpful and could add to their confusion and/or lead to more disappointment.
Ideally, you would take steps to prevent a 404 page from showing in the first place. Some of the ways you can prevent “page not found” errors include the following:
- Plan to set up well-structured permalinks from the beginning to avoid changing these the future
- Be proactive: monitor incorrect incoming links, then contact the owners of the websites that are linking to your site and request that these links be corrected. Most site owners will be more than happy to oblige.
- Don’t remove old content on your site unless it’s absolutely necessary to do so, and if you have to, make sure to set up proper redirection and follow correct page migration procedures.
- Look at your site’s analytics, or search online for terms such as “tracking inbound links”, or “reputation management tools” to find tools that can show you which sites are linking to your site.
- Use a plugin like Broken Link Checker to detect and redirect broken links on your site.
In addition to taking steps to prevent errors, the best thing you can do is to be as upfront and helpful as you can be. Think of ways to turn errors into opportunities. Acknowledge the fact that the content they are looking for is missing and try to help your visitors find what they are looking for.
At the very least, your 404 page should provide helpful information and some useful navigation options for your visitors. Explain to them why the page can’t be located and offer suggestions for helping them get to the right area of your site to continue searching.
Here are some ideas to help you create a useful 404 error page:
- Write a clear and simple greeting with apologies for the inconvenience
- Add site branding elements to reassure visitors that they are still on your site, and to give a clear indication of the industry and category your site or business belongs to
- Add helpful navigation options like a search form, links to relevant, recent and/or popular content
- Add links to your home page and your sitemap
- Add a link to your contact page with a simple request for reporting the error
- Add a tag cloud to your page
- Add some promotional content or information about your offers and services (optional)
- Add a notification and/or tracking system to help you identify 404 errors on your site.
Customizing Your WordPress 404 Error Page
A WordPress “404” error page is an actual page file that can be edited. It is typically included with most WordPress themes. You can find this page by logging into your server (e.g. via FTP, cPanel, etc.) and looking for a page called 404.php located inside the wp-content > themes > name of theme folder …
Once you have located the page, you can edit it to improve your visitor’s experience by placing helpful information in your 404 error pages (you can even monetize your 404 error pages by placing ads in it).
Below are just some examples of simple customizations you can make to your WP 404 page.
For example, you can add links pointing visitors to the main sections of your site …
(Direct visitors to the main sections of your website)
You can add links to relevant content, related content, or your latest content …
You can incorporate friendly, funny, clever, witty, or amusing messages …
You can even add a creative touch …
In short, you can customize your 404 error page however you like.
Note: Always make a backup of any files you plan to modify. Editing your WordPress 404 page requires some knowledge of editing PHP files, even if it’s doing something as simple as changing the greeting that your visitors will see when they arrive on your page …
If you are not comfortable editing code, ask someone with web design or PHP experience to do it for you. See the resources section at the bottom of this page for more information about editing your WordPress 404 page template.

More Useful 404 Plugins
The plugins below provide more advanced or unusual options to address 404 errors on your site.

Redirection is a very useful WordPress plugin that helps you manage 301 redirects, keep track of 404 errors, and generally tidy up any loose ends your site may have.
This plugin is particularly useful if you are migrating pages from an old website, or are changing the directory of your WordPress installation, as it allows you to map your old URLs to your new ones …
(WordPress Plugin – Permalinks Moved Permanently)
This simple but effective plugin is useful if you change the permalink structure of your site and don’t want to lose any incoming links pointing to your old page URLs.
If you just migrated your WordPress blog from one permalink structure to another, and you don’t want to lose the traffic that accesses your blog through the old permalinks, then consider using this plugin.
Here’s how the plugin works: Right before the old permalink generates a 404 error page, this plugin grabs the slug from the end of the request and checks to see if a post with the same slug is located somewhere else on your site. If so, the plugin will generate a “301 Moved Permanently” error and forward your visitor to the new location of your post.
In addition to redirecting your visitor to the new link, it will also automatically redirect visitors and search engine spiders to the new location in the future.
(WordPress Plugin – Useful 404s)
This plugin sends you email notifications that specify the cause of your errors, allowing you to create more useful 404 pages. The developer of this plugin credits the following article for inspiring the creation of this plugin: A More Useful 404.
