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: Apply the 3-click rule and flat-vs-deep tradeoffs to build ASCII tree sitemaps, with ready-made templates for SaaS, blog, e-commerce, documentation, hybrid, and small business sites. - Navigation & URL Specification: Define header nav (4-7 items), footer columns, breadcrumbs, and consistent URL patterns, with Mermaid diagram templates for visual sitemaps shareable with design teams. - Internal Linking Strategy: Implement hub-and-spoke content models, orphan page audits, and cross-section linking plans. - 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 (/integrations, /compare), keeps them out of the main nav, applies hub-and-spoke linking, and addresses crawl budget concerns. ## 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.
