## 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. If Google API credentials detected (`python scripts/google_auth.py --check`), also spawn seo-google agent
4. If local business detected, also spawn seo-local agent
5. If local business detected AND DataForSEO MCP available, also spawn seo-maps agent
6. If backlink APIs detected (`python scripts/backlinks_auth.py --check`), also spawn seo-backlinks agent
7. If Firecrawl MCP available, use `firecrawl_map` to discover all site URLs before analysis
8. Collect results and generate unified report with SEO Health Score (0-100)
9. Create prioritized action plan (Critical -> High -> Medium -> Low)
10. **Offer PDF report**: "Generate a professional PDF report? Use `/seo google report full`"

For individual commands, load the relevant sub-skill directly.
After any analysis command completes, offer to generate a PDF report via `scripts/google_report.py`.

## 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 --> auto-suggest `/seo local` for deeper analysis
- **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
- `references/local-seo-signals.md`: Local ranking factors, review benchmarks, citation tiers, GBP status
- `references/local-schema-types.md`: LocalBusiness subtypes, industry-specific schema and citation sources

Maps-specific references (loaded by seo-maps skill, not at startup):
- `references/maps-geo-grid.md`, `references/maps-gbp-checklist.md`, `references/maps-api-endpoints.md`, `references/maps-free-apis.md`

## 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)

## Error Handling

| Scenario | Action |
|----------|--------|
| Unrecognized command | List available commands from the Quick Reference table. Suggest the closest matching command. |
| URL unreachable | Report the error and suggest the user verify the URL. Do not attempt to guess site content. |
| Sub-skill fails during audit | Report partial results from successful sub-skills. Clearly note which sub-skill failed and why. Suggest re-running the failed sub-skill individually. |
| Ambiguous business type detection | Present the top two detected types with supporting signals. Ask the user to confirm before proceeding with industry-specific recommendations. |
