Site architecture

Architecture is what pages exist, how they nest, what their URLs are, and how they link: settle it before the platform, because the platform has to carry the plan, not the other way round [coreyhaines31/marketingskills, site-architecture]. This skill is coreyhaines31/marketingskills' site-architecture v2.1.0 (MIT, "Copyright (c) 2025 Corey Haines"), copied where quoted, with each rule checked against Google Search Central and the WAI-ARIA Authoring Practices; where they differ, the official form is written and the source's line is named.

XML sitemaps, crawl errors and technical SEO are in seo SKILL.md (the source routes them out the same way); pages built at scale from data are in seo PAGES-AT-SCALE.md; breadcrumb and other structured data in seo STRUCTURED-DATA.md; comparison pages in comparison-pages SKILL.md; what content to plan in content-strategy SKILL.md; auditing a live site in site-audit SKILL.md. The house pattern for the owner's own marketing sites (header, footer, language prefixes, routes) is landing-page-ui SKILL.md; where this generic skill disagrees, both are stated and the house pattern wins on those sites.

Apply only the routes and checks for the selected job. Read a linked skill's named file from its installed folder when available, or from the linked source. Report an unavailable required reference instead of inventing it. [skill-authoring, DISTRIBUTION.md#composing-skills]

Before planning

Read the project's product context first: .agents/product-context.md (anti-slop-copy CONTEXT.md; the source names this file .agents/product-marketing.md). Ask only for what it does not cover. Gather [coreyhaines31/marketingskills, site-architecture]:
