# SEO: Universal SEO Analysis Skill

Codex can invoke this skill from natural language ("audit this site", "check schema",
"run a technical SEO review") or from command-like prompts such as `/seo audit <url>`.
Use the matching specialist skill directly when the request is narrow.

**Scripts:** Located at the plugin root `scripts/` directory.

Comprehensive SEO analysis across all industries (SaaS, local services,
e-commerce, publishers, agencies). Orchestrates 26 specialized sub-skills and 24 Codex
agent profiles, with optional MCP-backed extensions for DataForSEO, Firecrawl, and image generation.

## Shared Data Cache

**Step 0 -- Check shared data cache:**

Before routing or gathering, check `.seo-cache/` for cached data from other skills.
Reference: `references/shared-data-cache.md` for schemas and dependency map.

Check these cache files when present:
- `.seo-cache/site-meta.json` for domain, business type, industry, and crawl context
- `.seo-cache/audit-scores.json` for audit summary context from a prior full audit
- `.seo-cache/pages/{url-slug}/page-analysis.json` for page-level specialist context

- If found: parse and use the data (note "Using cached [X] from [date]")
- If missing: proceed without it (note "No cached [X] found, gathering fresh")
- If JSON is corrupt or unreadable: treat it as missing and continue normally
- If the user says "refresh" or "re-run": ignore cache entirely

## 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. Create prioritized action plan (Critical -> High -> Medium -> Low)
14. **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.

- WARNING at 30+ location pages (enforce 60%+ unique content)
- HARD STOP at 50+ location pages (require user justification)
