Pages: 404 Error Page

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

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for brand voice, key pages, and Section 12 (Visual Identity).

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 (brand-visual-generator)
Avoid confusion: Users should not think they've left your domain
Mobile responsive: Test on all devices
