# 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.

## Quick Reference

| Command | What it does |
|---------|-------------|
| `/seo audit ` | Full website audit with parallel subagent delegation |
| `/seo page ` | Deep single-page analysis |
| `/seo sitemap ` | Analyze or generate XML sitemaps |
| `/seo schema ` | Detect, validate, and generate Schema.org markup |
| `/seo images ` | Image optimization analysis |
| `/seo technical ` | Technical SEO audit (8 categories) |
| `/seo content ` | E-E-A-T and content quality analysis |
| `/seo geo ` | AI Overviews / Generative Engine Optimization |
| `/seo plan ` | 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 |

## 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:

| Category | Weight |
|----------|--------|
| Technical SEO | 25% |
| Content Quality | 25% |
| On-Page SEO | 20% |
| Schema / Structured Data | 10% |
| Performance (CWV) | 10% |
| Images | 5% |
| AI Search Readiness | 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)
