Pages: 404 Error Page
Guides 404 error page design for UX, conversion recovery, and brand consistency.
When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
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)
