What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages get buried, navigation becomes cluttered, URLs become inconsistent, and internal linking is neglected. This Skill provides a structured methodology for designing page hierarchies, navigation systems, URL patterns, 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 principles 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: Generate URL maps with consistent patterns, header/footer/sidebar navigation layouts, and breadcrumb implementations aligned to the hierarchy. - Internal Linking Strategy: Design hub-and-spoke content models, audit orphan pages, and plan cross-section links. - 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 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.
