What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages get buried, navigation becomes cluttered, URLs grow inconsistent, and internal linking is neglected. This Skill provides a structured methodology for designing page hierarchies, navigation systems, URL structures, and internal linking plans that work for both users and search engines. ## Core Features & Use Cases - Page Hierarchy Design: Applies the 3-click rule and flat-vs-deep tradeoffs to produce ASCII tree sitemaps and Mermaid visual sitemaps with navigation zones. - Navigation & URL Planning: Delivers header/footer/sidebar navigation specs, breadcrumb formats, and consistent URL patterns per page type (features, blog, docs, comparisons, integrations). - Internal Linking Strategy: Builds hub-and-spoke content models, orphan page audits, and cross-section linking plans. - Use Case: A SaaS company adding 200 programmatic integration pages asks how they fit into the site. The Skill recommends hub pages at /integrations, keeps them out of the main nav, defines URL patterns, and maps the hub-and-spoke internal linking model. ## 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.
