# SEO: Universal SEO Analysis Skill

## 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. If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent
9. If e-commerce detected, also spawn seo-ecommerce agent
10. If drift baseline exists for this URL (`python scripts/drift_history.py <url>`), also spawn seo-drift agent
11. Always include seo-sxo in full audits (search experience applies to all sites)
12. Collect results and generate unified report with SEO Health Score (0-100)
13. **Synthesize via the 10-principle framework** (see "Synthesis Methodology" below) — walk PERCEIVE → ANALYZE → VALIDATE → ACT before bucketing findings into Critical / High / Medium / Low
14. Create prioritized action plan with dependency sequencing + falsifiability per recommendation
15. **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`.

## Synthesis Methodology

Audits are not just findings — they are findings synthesized into a coherent
strategy. seo-skills uses a 10-principle thinking framework grouped into four
phases: **PERCEIVE** (observe-external · observe-internal · listen),
**ANALYZE** (think · connect-lateral · connect-system), **VALIDATE** (feel ·
accept), **ACT** (create · grow).

Full audits (`/seo audit`, `/seo page`) walk every phase before emitting the
action plan. Narrower commands (`/seo schema`, `/seo images`, etc.) pass at
least THINK + ACCEPT before emitting (sound first principle, surfaced
falsifiability). The Critical / High / Medium / Low priority buckets are the
**output** of validation, not a substitute for it.

Full methodology + per-principle SEO mapping: `references/thinking-framework.md`.

Each emitted recommendation should carry:
- The first-principle observation it rests on (THINK)
- The dependency on / unblock relationship to other recommendations (CONNECT-system)
- An explicit "how would we know this failed?" check (ACCEPT)
- A leading indicator the user can monitor without re-running the audit (GROW)

## 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

- `references/cwv-thresholds.md`: Current Core Web Vitals thresholds and measurement details
- `references/schema-types.md`: All supported schema types with deprecation status
