Invocation: /seo $1 $2 where $1 is the command and $2 is the URL or argument.

Scripts: Located at the plugin root scripts/ directory.

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 24 sub-skills (21 core + 1 framework integration + 2 extension mirrors) and 18 sub-agents. A separate optional Firecrawl extension is also installable (see "Optional Extensions" below).

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

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. |
