Orchestrates 12 specialized sub-skills and 7 subagents (+ optional extension sub-skills like seo-dataforseo). ## When to Use - Use when the user asks for a full SEO audit or broad SEO strategy. - Use as the umbrella entry point when multiple SEO dimensions are in scope. - Use when the task spans technical SEO, content, schema, sitemaps, and AI search readiness together. ## Quick Reference | Command | What it does | | ----------------------------------------- | ---------------------------------------------------- | | `/seo audit <url>` | Full website audit with parallel subagent delegation | | `/seo page <url>` | Deep single-page analysis | | `/seo sitemap <url or generate>` | Analyze or generate XML sitemaps | | `/seo schema <url>` | Detect, validate, and generate Schema.org markup | | `/seo images <url>` | Image optimization analysis | | `/seo technical <url>` | Technical SEO audit (9 categories) | | `/seo content <url>` | E-E-A-T and content quality analysis | | `/seo geo <url>` | AI Overviews / Generative Engine Optimization | | `/seo plan <business-type>` | Strategic SEO planning | | `/seo programmatic [url\|plan]` | Programmatic SEO analysis and planning | | `/seo competitor-pages [url\|generate]` | Competitor comparison page generation | | `/seo hreflang [url]` | Hreflang/i18n SEO audit and generation | | `/seo dataforseo [command]` | Live SEO data via DataForSEO (extension) | | `/seo image-gen [use-case] <description>` | AI image generation for SEO assets (extension) | ## Orchestration Logic When the user invokes `/seo audit`, delegate to subagents in parallel: 1. Detect business type (SaaS, local, ecommerce, publisher, agency, other) 2. Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo 3. Collect results and generate unified report with SEO Health Score (0-100) 4. Create prioritized action plan (Critical -> High -> Medium -> Low) For individual commands, load the relevant sub-skill directly. ## Industry Detection Detect business type from homepage signals: - **SaaS**: pricing page, /features, /integrations, /docs, "free trial", "sign up" - **Local Service**: phone number, address, service area, "serving [city]", Google Maps embed - **E-commerce**: /products, /collections, /cart, "add to cart", product schema - **Publisher**: /blog, /articles, /topics, article schema, author pages, publication dates - **Agency**: /case-studies, /portfolio, /industries, "our work", client logos ## Quality Gates Read `references/quality-gates.md` for thin content thresholds per page type.
