What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages get buried, navigation becomes cluttered, URLs become inconsistent, and orphan pages hurt SEO. This Skill guides the design of 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: Applies the 3-click rule and flat-vs-deep tradeoffs to produce ASCII tree structures and Mermaid visual sitemaps with navigation zones. - URL Structure Planning: Provides URL patterns per page type (features, blog, docs, comparisons, integrations) with rules for redirects, slugs, and consistency. - Navigation & Internal Linking: Designs header, footer, sidebar, and breadcrumb navigation plus hub-and-spoke internal linking strategies with an orphan-page audit checklist. - Use Case: A SaaS team adding 200 programmatic integration pages and 50 comparison pages asks how they fit into the site; the Skill recommends hub pages, URL patterns, and linking without cluttering the main nav. ## Quick Start Ask the assistant to plan the site architecture for your website, describing your site type, main sections, and any existing pages that need reorganizing.
