SEO — Universal SEO Analysis Skill

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 12 specialized sub-skills and 6 subagents (+ optional extension sub-skills).

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
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 only for government and healthcare sites
• 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)
