What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages pile up, navigation becomes cluttered, URLs grow inconsistent, and important content gets buried. This Skill provides a structured methodology 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: Applies the 3-click rule and flat-vs-deep principles to produce ASCII tree structures and Mermaid visual sitemaps for any site type (SaaS, blog, e-commerce, docs, small business). - URL & Navigation Specification: Generates URL maps with consistent patterns, header/footer navigation specs, breadcrumb formats, and mobile navigation guidance. - Internal Linking Strategy: Designs hub-and-spoke content models, cross-section linking, and orphan page audits for restructuring projects. - 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, applies hub-and-spoke linking, and delivers a full URL map and navigation spec. ## 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.
