When to Use

• Use when the user asks for a full SEO audit or broad SEO strategy.

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:

Category	Weight
Technical SEO	22%
Content Quality	23%
On-Page SEO	20%
Schema / Structured Data	10%
Performance (CWV)	10%
AI Search Readiness	10%
Images	5%

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)
