Summary

After loading this skill, the agent can execute full-site SEO audits (or single-page, technical, content, schema, local, or competitor analysis) by auto-detecting the business type and delegating to specialized subagents in parallel, then synthesizing results into a prioritized action plan with a 0–100 health score. Invoke on any audit, optimization, or SEO strategy request.

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
