Use Custom 404 Pages to Improve UX & SEO: A Must-Have for Every Website

When users click a broken link or type an incorrect URL, they often land on your site’s 404 error page. While this might seem like a frustrating dead end, it’s actually a hidden opportunity. A custom-designed 404 page not only softens the impact of the error but also plays a crucial role in enhancing user experience (UX) and maintaining your website’s SEO health.

Instead of serving a default error message, a well-crafted 404 page can guide visitors back to relevant content, encourage further exploration, and keep your bounce rate low. This reduces friction, builds trust, and signals to search engines that your site is user-centric, organized, and well-maintained.

Why a Custom 404 Page Is Important for SEO & UX

A generic 404 error page often frustrates users and causes them to leave your website immediately. In contrast, a well-designed 404 page can:

Retain Users: Provide helpful navigation that guides users back to active pages.
Preserve SEO Value: Reduce bounce rate and improve session time — both are behavioral signals that search engines use to evaluate site quality.
Reflect Brand Professionalism: A branded error page shows attention to detail and builds trust with visitors.

How to Create a Custom 404 Page in Webflow

Follow these simple steps to design a user-friendly, on-brand 404 experience:

Step 1: Create the 404 Page in Webflow

1. Log in to your Webflow dashboard.

2. In the Pages panel, click “+ Add Page.”

3. Name the page exactly: 404 (This is required — Webflow automatically assigns it as your 404 error page.)

SEO Tip: Even though search engines don’t index 404 pages, designing one with clear internal links helps preserve traffic and reduce bounce rates.

Step 2: Add Helpful Elements to Guide Users

A 404 page should be friendly, useful, and action-oriented — not just an apology.

Include the following:

• A clear message like:
  “Oops! This page doesn’t exist or may have moved.”

• Navigation links to key pages:

  • Homepage

  • Blog

  • Services or Portfolio

  • Contact page (optional)

• Optional but impactful:

  • A search bar to help users find what they were looking for

  • A contact form to report broken links or ask for help

Step 3: Design the Page to Match Your Brand

A 404 page should feel like the rest of your site — not like an afterthought.

• Use your brand colors, fonts, and layout styles

• Add a fun illustration, animation (Lottie), or friendly icon to ease frustration

• Keep the design clean and focused — avoid clutter

Pro Tip: Use humor or storytelling to create a positive emotional response. This increases the chance that the user will continue exploring.

Step 4: Test Your 404 Page

Once your design is complete:

1. Publish your website

2. In your browser, type a fake URL like yourdomain.com/test-404

3. Confirm that the custom 404 page displays correctly, and all navigation buttons or links work as intended

Pro Tip: Use a Strategic Call-to-Action (CTA) on Your 404 Page

A user landing on a 404 page doesn’t have to be the end of their journey — it can be the beginning of deeper engagement. By placing a clear, compelling call-to-action (CTA) on your error page, you can turn a potential bounce into a conversion or continued interaction.

Why a CTA Matters on a 404 Page:

• Keeps users engaged instead of exiting the site

• Offers direction when the original path is broken

• Reinforces brand value and professionalism

• Helps boost session duration — a behavioral metric that influences SEO

Effective CTA Ideas for 404 Pages:

• Return to Homepage – Redirect users to your primary content hub

• Explore Our Work – Perfect for portfolio or service-based websites

• Visit Our Blog – Keep readers exploring your educational content

• Contact Support – Useful for SaaS, eCommerce, or service providers

Implementation Tips:

1. Use a Bold, High-Contrast Button

Design your CTA button with strong visual weight. Use a bold color that contrasts against the background and aligns with your brand palette. The button should be instantly noticeable without clashing.

• Make it large enough to tap easily on mobile devices
  
  

• Add icons like arrows or rockets to draw visual attention
  
  

2. Keep the CTA Message Friendly & Action-Oriented

Choose clear, concise, and helpful text that guides the user — avoid technical or robotic language.

Examples of user-friendly CTA text:

• Back to Home
  
  

• Discover Our Work
  
  

• Read Our Blog
  
  

• Contact Us for Help
  
  

These encourage users to stay on your site and explore something valuable.

3. Place the CTA “Above the Fold”

Make sure the CTA appears immediately on page load, without requiring the user to scroll. This improves usability, especially on mobile devices where screen real estate is limited.

• Position the button right below the main error message
  
  

• Avoid pushing it down with unnecessary content

Final Thoughts

A custom 404 page is a small investment with big rewards. It not only prevents user frustration, but also helps maintain SEO integrity and keeps your site feeling polished and professional.

By using Webflow’s built-in functionality and following simple UX principles, you can create a 404 page that supports your site’s performance, credibility, and search visibility — even when things go wrong.
