What problem does it solve? Planning or restructuring a website's information architecture is hard to do systematically: pages get buried, navigation becomes cluttered, URLs grow inconsistent, and orphan pages hurt SEO. This Skill provides a structured methodology for designing page hierarchies, navigation, URL patterns, and internal linking so sites are intuitive for users and optimized for search engines. ## Core Features & Use Cases - Page Hierarchy Design: Apply the 3-click rule and flat-vs-deep tradeoffs to build ASCII tree sitemaps and Mermaid visual sitemaps for any site type (SaaS, blog, e-commerce, docs, hybrid, small business). - URL Structure & Navigation Specs: Define consistent URL patterns per page type, header/footer/sidebar navigation layouts, and breadcrumb implementations aligned with URL paths. - Internal Linking Strategy: Design hub-and-spoke content models, eliminate orphan pages, and audit anchor text and cross-section links. - Use Case: A SaaS team adding 200 programmatic integration pages and 50 comparison pages gets hub page recommendations, URL patterns like /integrations/{name}, and a linking plan that keeps the main nav clean. ## 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.
