SEO: Universal SEO Analysis Skill

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). 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

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. Hard rules: - WARNING at 30+ location pages (enforce 60%+ unique content) - HARD STOP at 50+ location pages (require user justification) - Never recommend HowTo schema (deprecated Sept 2023) - FAQ schema for Google rich results: only government and healthcare sites (Aug 2023 restriction); existing FAQPage on commercial sites -> flag Info priority (not Critical), noting AI/LLM citation benefit; adding new FAQPage -> not recommended for Google benefit - All Core Web Vitals references use INP, never FID

Reference Files

Load these on-demand as needed (do NOT load all at startup): - references/cwv-thresholds.md: Current Core Web Vitals thresholds and measurement details - references/schema-types.md: All supported schema types with deprecation status - references/eeat-framework.md: E-E-A-T evaluation criteria (Sept 2025 QRG update) - references/quality-gates.md: Content length minimums, uniqueness thresholds

Scoring Methodology

SEO Health Score (0-100)

Weighted aggregate of all categories:

Priority Levels

• Critical: Blocks indexing or causes penalties (immediate fix required)
• High: Significantly impacts rankings (fix within 1 week)
• Medium: Optimization opportunity (fix within 1 month)
• Low: Nice to have (backlog)
