Pages: 404 Error Page

Guides 404 error page design for UX, conversion recovery, and brand consistency.

Initial Assessment

Check for product marketing context first: If

.claude/product-marketing-context.md

or

.cursor/product-marketing-context.md

exists, read it for brand voice and key pages.

Identify:

Site structure: Key pages to link (homepage, popular pages, search)
Brand tone: Friendly, professional, playful
Conversion goal: Recover lost visitors, drive to key pages

Best Practices

Clear Error Messaging

User-friendly: Neutral message explaining the page wasn't found
Optional 404 display: Can show "404" but avoid blaming the user
Empathetic tone: Acknowledge the error gracefully; turn frustration into opportunity

Navigation and Redirection

Element	Purpose
Site navigation	Header/footer so users know they're still on your site
Search	Help users find what they need
Popular pages	Links to homepage, features, pricing, blog
Similar URLs	Suggest corrections for common typos
Avoid auto-redirect	Unless confident of user intent

Design and Branding

Consistent design: Same header, footer, colors as rest of site
Avoid confusion: Users should not think they've left your domain
Mobile responsive: Test on all devices

Conversion Opportunities

404 pages can drive conversions by:

Showcasing popular products or features
Featuring testimonials or social proof
Offering special promotions or value
Linking to mobile app or newsletter

Technical

Track 404s: Monitor broken links, fix or redirect
Accessibility: Maintain WCAG standards
HTTP status: Ensure proper 404 response code

Output Format
