What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages pile up without clear hierarchy, navigation becomes cluttered, URLs grow inconsistent, and important content gets buried. This Skill provides structured frameworks for designing page hierarchies, navigation systems, URL patterns, and internal linking so sites are intuitive for users and optimized for search engines. ## Core Features & Use Cases - Page Hierarchy Design: Apply the 3-click rule and flat-vs-deep principles to build ASCII tree sitemaps with URL annotations for SaaS, e-commerce, content, documentation, and small business sites. - Navigation & URL Planning: Design header, footer, sidebar, and breadcrumb navigation with concrete rules (4-7 header items, CTA placement), plus consistent URL patterns per page type. - Visual Sitemaps & Internal Linking: Generate Mermaid diagram sitemaps with navigation zones and color coding, and plan hub-and-spoke internal linking with orphan page audits. - Use Case: A SaaS company adding 200 programmatic integration pages and 50 comparison pages asks how they fit into the site. The Skill recommends hub pages at /integrations and /compare, hub-and-spoke linking, and keeping them out of the main nav. ## Quick Start Ask the agent to plan the site architecture for your website, describing your site type, existing pages, and goals, and receive a page hierarchy, URL map, navigation spec, and internal linking plan.
