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 principles to produce ASCII tree sitemaps and Mermaid visual sitemaps with navigation zones. - Navigation & URL Standards: Delivers header, footer, sidebar, and breadcrumb specifications plus consistent, human-readable URL patterns for every page type. - 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, keeps them out of the main nav, defines URL patterns, and maps the internal linking structure. ## Quick Start Ask the assistant to plan the site architecture for your website, describing your site type, main sections, and whether it is a new build or a restructure.
