The project codebase is in your current working directory. Explore the files to understand the code before making changes. boss just asked for an SEO strategy deck by end of week for a new SaaS we're launching — it's a B2B observability tool for ML/LLM apps (competitors: LangSmith, Arize, WhyLabs). Put together a full SEO plan: target keyword clusters, pillar pages, programmatic SEO opportunities, schema strategy, and a 90-day action plan with priorities. Treat this as `/seo plan saas` — no live site yet, just plan from the business context.

Now I have full context on the skill framework and reference files. Let me build the comprehensive SEO strategy deck.

The strategy deck is ready at seo-strategy-deck.md (971 lines, ~6,000 words). Here's a summary of what's in it:

What's in the Deck

1. Market & Competitive Landscape

Breakdown of LangSmith, Arize, and WhyLabs — their SEO moats, content strategies, and 5 specific gaps we can exploit (LLM-specific framing, comparison pages, integration pages, compliance content, prompt engineering).

2. Target Keyword Clusters (6 clusters, 60+ keywords)

  • Core product — llm observability, llm monitoring tool, etc. (bottom-funnel, map to product pages)
  • Competitor/comparison — langsmith alternatives, arize vs whylabs, etc. (decision-stage buyers)
  • Use-case/problem-aware — llm hallucination detection, rag evaluation metrics (mid-funnel)
  • Educational — what is llm observability, llmops (top-funnel, topical authority)
  • Integration/ecosystem — openai api monitoring, langchain observability (30+ pages)
  • Compliance/enterprise — ai compliance monitoring, eu ai act compliance tools (high-ACV)

3. Site Architecture & 5 Pillar Pages

Full URL structure with clean hierarchy. Five detailed pillar pages with outlines, word counts, and cluster link maps:

  1. "Complete Guide to LLM Observability" (top priority)
  2. "LLM Evaluation: Metrics, Methods & Best Practices"
  3. "LLMOps Definitive Guide"
  4. "AI Compliance & Governance"
  5. "RAG Architecture Guide"

4. Programmatic SEO (4 template types, 100+ pages)

  • Integration pages (/integrations/[name]/) — 30–50 pages with full template spec
  • Comparison pages (/compare/[competitor]/) — 8–12 pages, includes mandatory "Where Competitor Wins" section for E-E-A-T
  • Glossary (/glossary/[term]/) — 60–100 entries organized by category
  • "Best tools" listicles — 8–12 roundup pages

All have quality gates enforced: unique intros, no empty template variables, internal linking density, uniqueness thresholds.

5. Schema Strategy

Full JSON-LD templates for every page type — Organization, WebSite, BlogPosting, SoftwareApplication, Product+Offer for pricing. Follows all current rules (no HowTo, no FAQPage for commercial sites, @graph pattern).

6. AI Search / GEO Readiness

  • llms.txt manifest template
  • Citability optimization rules (lead with extractable definitions)
  • Brand mention co-occurrence strategy
  • robots.txt allowing GPTBot, PerplexityBot, Claude-Web, Google-Extended

7. Technical SEO Foundation

Core requirements table (HTTPS, CWV with INP, canonical tags, sitemap strategy, rendering approach — SSG with Next.js/Astro recommended).

8. E-E-A-T Plan

How to build Experience, Expertise, Authoritativeness, and Trust from zero — original research, author pages with Person schema, open-source projects for backlinks, conference talks, and guest posts.

9. 90-Day Action Plan

Week-by-week with specific tasks, owners, and priorities:

  • Days 1–30: Technical foundation + first 15–20 pages + Pillar 1
  • Days 31–60: Programmatic templates live, 60–80 pages, Pillar 2, open-source launch
  • Days 61–90: 100–130 pages, all 5 pillars, GSC-driven optimization, case studies

10. KPIs & Measurement

Monthly targets for indexed pages, organic impressions/clicks, referring domains, CWV pass rate, plus a 12-week content calendar and a 48-hour post-launch quick wins checklist.

SEO: Universal SEO Analysis Skill

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 12 specialized sub-skills and 7 subagents (+ optional extension sub-skills like seo-dataforseo).

When to Use

  • Use when the user asks for a full SEO audit or broad SEO strategy.
  • Use as the umbrella entry point when multiple SEO dimensions are in scope.
  • Use when the task spans technical SEO, content, schema, sitemaps, and AI search readiness together.

Quick Reference

CommandWhat it does
/seo audit <url>Full website audit with parallel subagent delegation
/seo page <url>Deep single-page analysis
/seo sitemap <url or generate>Analyze or generate XML sitemaps
/seo schema <url>Detect, validate, and generate Schema.org markup
/seo images <url>Image optimization analysis
/seo technical <url>Technical SEO audit (9 categories)
/seo content <url>E-E-A-T and content quality analysis

/seo hreflang [url]Hreflang/i18n SEO audit and generation
/seo dataforseo [command]Live SEO data via DataForSEO (extension)
/seo image-gen [use-case] <description>AI image generation for SEO assets (extension)

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. 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 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
