How to Create a 404 Error Page That Actually Works for Your Startup

Most founders think of the 404 error page as a “dead end.” In reality, it’s a second chance. Done wrong, it frustrates visitors and pushes them to competitors. Done right, it keeps them on-site, builds trust, and even converts.

When a Sydney ecommerce startup replaced their generic 404 page with a branded, funny design that linked to their shop categories and bestsellers, bounce rates dropped 35% — and conversions actually increased.

Your 404 page isn’t just about handling mistakes. It’s about showing personality, providing options, and guiding users back on track.

What Exactly Is a 404 Error Page?

A 404 Error Page appears when a user tries to access a page that doesn’t exist. This can happen because of:

• Broken links

• Deleted or renamed pages

• Typos in the URL

• Outdated external links

Instead of showing a dull “Page not found,” your 404 should be a helpful and branded recovery tool.

Core Sections to Include

• Clear, human message (“Oops, that page doesn’t exist”)

• Navigation links back to key pages (Home, Shop, Blog, Contact)

• Search bar to help users find what they need

• Suggested popular pages or categories

• Call to action (CTA) — e.g., browse products, sign up, or contact support

Extra Features That Add Value

• Smart redirects (e.g., if a page was moved, send users to the new one)

• Funny or branded visuals (mascot, illustration, or tone that matches your brand)

• Email capture or special offer (“Since you’re here, grab 10% off”)

• Tracking (so you can monitor how often users hit 404s and fix root causes)

Why This Could Make or Break Your User Experience

Credibility: A generic 404 looks sloppy; a custom one signals care and professionalism.

Bounce prevention: Keeps users engaged instead of closing the tab.

Conversion opportunity: Turn lost visitors into subscribers or customers.

SEO health: While 404s themselves don’t harm SEO, poor handling (like soft 404s) can. Redirecting to relevant content strengthens site authority.

Before You Start

Prepare these assets:

• Short, brand-friendly error message

• Links to top pages (home, categories, contact)

• High-quality image, GIF, or design element

• Optional: coupon code, signup form, or CTA graphic

How to Build a 404 Error Page:

Step by Step

Step 1: Write a Friendly, Clear Message

• Example: “Oops! Looks like you took a wrong turn.”

• Result: Humanises the error, reduces frustration.

Step 2: Add Navigation Options

• Include a button back to Home, main categories, or your Help Centre.

• Result: Visitors immediately know where to go next.

Step 3: Include a Search Bar

• Helps users self-correct.

• Result: Keeps them exploring instead of leaving.

Step 4: Showcase Popular Content

• Highlight top products, blog posts, or events.

• Result: Turns a mistake into a discovery.

Step 5: Add a Conversion Hook

• Example: “Since you’re here, get 10% off your first order.”

• Result: Recovers potentially lost leads.

Step 6: Match Branding & Personality

• Add illustrations, humour, or tone consistent with your brand.

• Result: Reinforces brand trust and memorability.

Step 7: Track & Fix Broken Links

• Use tools like Google Search Console or Ahrefs to monitor 404 hits.

• Result: Reduces future 404s and improves SEO.

Mistakes to Avoid

Blank, technical error messages — they push users away.

No navigation — leaving users stranded.

Redirecting all 404s to homepage — bad UX and confuses Google.

Not monitoring errors — you’ll keep losing traffic without knowing why.

Real-World Examples

• Australian fashion retailer: Turned their 404 into a mini shop window with featured products → reduced bounce rate by 28%.

• SaaS company in Melbourne: Added a cheeky GIF and a link to their Help Centre → customers reported finding answers faster.

• Brisbane fintech startup: Used a “report this issue” link on their 404 → spotted broken links 40% faster.

What It Costs and How Long It Takes

• DIY / In-house: $0–$100 AUD | 1–2 hours | Use CMS templates.

• Custom design: $300–$800 AUD | 2–4 days | Branded illustration + UX polish.

• Pro setup with tracking & redirect rules: $800–$2,000 AUD | 1 week.

Hidden Costs

• Lost leads when users bounce.

• Poor impression with investors or press.

• Missed conversions from visitors already interested in your brand.

Mentor Tip

Treat your 404 page like a mini landing page. Offer value, guide the next step, and track behaviour to improve over time.

Designer Tip: Treat this like a mini landing page — each element should have a clear visual hierarchy:

• Big headline first,

• then main navigation,

• then extras (search, suggestions, offers),

then footer safety net.

FAQs

Do I really need a custom 404 page? 

Yes — a generic one increases bounce and frustration.

Should I redirect all 404s to the homepage? 

No. It confuses users and hurts SEO. Only redirect if there’s a relevant replacement.

Can I use humour on a 404 page? 

Definitely — as long as it fits your brand tone and doesn’t get in the way of navigation.

How do I know if users hit 404 pages often? 

Check Google Analytics (404 pageviews) or Search Console.
