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
  3. Collect results and generate unified report with SEO Health Score (0-100)
  4. Create prioritized action plan (Critical → High → Medium → Low)

For individual commands, load the relevant sub-skill directly.

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
  • 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 only for government and healthcare sites
  • 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
