Orchestration Logic
When the user invokes /seo audit, delegate to subagents in parallel:
- Detect business type (SaaS, local, ecommerce, publisher, agency, other)
- Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual
- Collect results and generate unified report with SEO Health Score (0-100)
- 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
