How To Create A Custom 404 Page In WordPress

When visitors land on a broken or missing page, a standard “404 Page Not Found” can be frustrating and may cause them to leave your site. A custom 404 page improves user experience, keeps visitors engaged, and even helps your SEO.

In this guide, we’ll show you how to create a custom 404 page in WordPress, why it matters, and some tips for design and content.

Why A Custom 404 Page Is Important

A well-crafted 404 page can:

Reduce bounce rates by guiding visitors back to useful content.
Keep your brand tone consistent.
Help users find the content they were looking for via menus, search, or links.
Can be an opportunity to promote products, services, or popular blog posts.
Signal to search engines that your site is user-friendly.

Step 1: Decide On Your 404 Page Content

Before building, decide what your page will include:

A friendly message explaining the error.
Links to main pages (Home, Blog, Contact).
A search bar.
Popular posts or products.
Optional CTA like signing up for a newsletter.

Step 2: Using WordPress Theme 404 Template

Most WordPress themes come with a 404.php template file. To customise it:

Go to your theme folder (via FTP or WordPress editor)
Locate 404.php
Edit the file using HTML/PHP to include your message, links, or search bar

Tip: If editing code isn’t comfortable, use a child theme so updates don’t overwrite your changes.

Step 3: Using A Page Builder (Elementor, Divi, Or Beaver Builder)

Many modern themes or page builders let you create a custom 404 page without touching code:

Elementor:

Go to Templates → Theme Builder → Single → 404 Page
Add sections, headings, buttons, and a search widget
Publish and assign as your default 404 page

Divi:

Create a new layout
Include modules for text, buttons, and search
Save and assign via Theme Builder

Step 4: Redirect Broken URLs (Optional)

Sometimes it makes sense to redirect old or mistyped URLs to relevant pages.

Use a plugin like Redirection
Track 404 errors with Google Search Console
Redirect to home page, category, or relevant content

Step 5: Test Your 404 Page

Once your page is live:

Visit a non-existent URL on your domain to see the 404 page in action
Check that search, links, and CTAs work correctly
Test on desktop and mobile for responsiveness

Include visual elements like images, illustrations, or icons

Consider including a search bar or contact option
