What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages pile up without clear hierarchy, navigation becomes cluttered, URLs are inconsistent, and important content gets buried. 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 structures and Mermaid visual sitemaps for any site type (SaaS, blog, e-commerce, docs, small business). - Navigation & URL Planning: Generates header/footer/sidebar navigation specs, breadcrumb formats, and consistent URL pattern maps with redirect guidance for restructures. - Internal Linking Strategy: Builds hub-and-spoke content models, orphan page audits, and cross-section linking plans. - Use Case: A SaaS company adding 200 integration pages and 50 comparison pages asks how they fit into the site. The Skill recommends hub pages at /integrations and /compare, keeps them out of the main nav, and defines the hub-and-spoke linking model. ## 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.
