Claude Code SEO Skills: 9 Repos vs ClaudeFast Growth Kit

A Claude Code SEO skill is a folder of instructions, scripts, and reference data Claude loads when running SEO workflows: keyword research, on-page audits, schema markup, content briefs, GEO citation optimization, or Google Search Console analysis. SEO in 2026 has fractured into three jobs (classic SEO, GEO for AI search, content engineering), and most standalone repos cover one job. ClaudeFast's Growth Kit ships all three as one integrated 9-workflow system with 13 SEO files and a 2,000+ line master reference.

Quick verdict: Standalone SEO skill repos (claude-seo at 4.1k stars, geo-seo-claude at 4.8k, seomachine at 3.3k) cover individual SEO jobs but require you to wire data sources, methodology, and GEO patterns yourself. ClaudeFast Growth Kit ships a complete 9-workflow lettered SEO system (Audit, Content, GSC Reports, GEO, Indexing, Rank, Strategy, Technical, Competitive Intelligence) with a 2,000-line master reference and direct GSC MCP integration.

Why SEO Fragmented in 2026

Three forces split SEO into separate jobs:

1. AI search citation became measurable. AI-referred traffic grew 527% year-over-year (per AI search analytics studies), and AI traffic converts at 4.4x the rate of organic search. Google's AI Overviews, ChatGPT, Perplexity, and Gemini cite different sources for the same query. Princeton's 2024 GEO research showed citation patterns that don't match traditional ranking signals.
2. Content production scaled. Skills can generate publishable content in minutes. The bottleneck moved from writing to strategy (what to write) and quality (does it cite, does it rank, does it convert).
3. Data layers became APIs. GSC, Ahrefs, BigQuery, and DataForSEO all expose SEO data as MCP servers. The skill layer that consumes them became more valuable than the skills that guess.

A skill repo that ignores any of these three forces is solving 2024's SEO problem. The repos below all solve at least one. ClaudeFast Growth Kit solves all three.

Quick Win: Wire One SEO MCP in 60 Seconds

If you want real GSC data in Claude Code right now:

{
  "mcpServers": {
    "gsc": {
      "command": "node",
      "args": ["~/.mcp-servers/gsc-mcp/dist/index.js"],
      "env": { "GSC_REFRESH_TOKEN": "your-token" }
    }
  }
}

That gives you Suganthan Mohanadasan's GSC MCP with 20 tools (quick wins, cannibalization, content decay, CTR benchmarking, indexing API). Now Claude can query your real Google Search Console data without leaving the terminal.

7. Suganthan-Mohanadasan/Suganthans-GSC-MCP (55 stars)

MCP server for Google Search Console with 20 tools: quick wins, cannibalization, content decay, CTR benchmarking, alerting, indexing API. TypeScript.

Strongest piece: Each of the 20 tools maps to a real SEO question (which queries are losing impressions, which pages have CTR below SERP benchmark, which queries cannibalize each other).

What you still build: The skill layer that consumes the data and turns it into action.

8. seo-skills/seo-audit-skill (78 stars)

CLI tool with 108 audit rules across 12 categories. Analyzes any website for SEO best practices, Core Web Vitals, security headers, structured data, accessibility. TypeScript.

9. Suganthan-Mohanadasan/awesome-seo-tools (46 stars)

Curated list of 208+ SEO tools maintained by an SEO professional, not a list-maintainer.

Best for: Discovery, not installation.

ClaudeFast Growth Kit SEO: The Integrated Alternative

ClaudeFast Growth Kit's SEO sub-skill ships 13 markdown files including a 2,000+ line master reference organized as a 9-workflow lettered system:

Three differentiators matter for this comparison:

1. The GEO workflow encodes Princeton's KDD 2024 research. Five-dimension citability scoring (Answer Block Quality, Passage Self-Containment, Structural Readability, Statistical Density, Uniqueness) with weighted formulas. Per-platform optimization for the five major AI search engines. Brand authority scoring across YouTube (0.737 correlation with citation), Reddit, Wikipedia, LinkedIn.

2. Workflows reference each other. The Strategy workflow feeds the Content workflow which applies GEO citability patterns from the GEO workflow which gets validated against GSC data via the GSC Reports workflow. Standalone packs require you to build this connective tissue.

3. The 2,000+ line master reference is the methodology layer. The reference covers content tiers, GEO citation formats (comparison articles drive 33% of citations, definitive guides 15%), AI crawler tier system, llms.txt patterns, and the entire content brief template. Standalone packs ship execution; ClaudeFast Growth Kit ships methodology.

Side-by-Side: Standalone vs ClaudeFast Growth Kit SEO

The GEO Edge: Why It Matters for SEO Choice in 2026

GEO is no longer optional. Three numbers from Princeton's 2024 GEO study and follow-up research:

• Adding citations gives +40% AI visibility lift
• Adding statistics gives +37% lift
• Keyword stuffing gives -10% (actively reduces visibility)

Most standalone SEO packs were built before this research was actionable. zubair-trabzada/geo-seo-claude (4.8k) and Auriti-Labs/geo-optimizer-skill (252) cover GEO well in isolation. None of the other seven packs ship a GEO-optimized content pipeline. ClaudeFast Growth Kit ships GEO as Workflow G, integrated with Content (C), Strategy (S), and Technical (T). When the Content workflow drafts a post, it applies GEO citability patterns automatically.

When Standalone Packs Win

Three honest scenarios:

1. You need exactly one SEO job. If you only need a technical audit, seo-audit-skill (78 stars) does that one thing well.
2. You're an SEO with a strong playbook. Layering claude-seo (4.1k) onto your own methodology works.
3. You want pure GEO without classic SEO. geo-seo-claude (4.8k) is a strong narrow pick.

When ClaudeFast Growth Kit SEO Wins

Five scenarios where the math favors integration:

1. You're running both classic SEO and GEO. Most teams need both. ClaudeFast Growth Kit covers both with shared methodology.
2. You want GSC data driving content decisions. Workflow D queries GSC, Workflow R prioritizes striking-distance pages, Workflow C creates the content. Standalone packs require you to build this loop.
3. You're a non-developer running SEO solo. Wiring 5 standalone SEO packs is engineering work that defeats the point.
4. You need auditable AI output. ClaudeFast Growth Kit content cites the citability dimension it optimized for. "Improved Statistical Density (+37% expected lift, Princeton 2024)" is reviewable. "Generated draft" is not.
5. You also need marketing, CRO, or product validation. ClaudeFast Growth Kit SEO ships alongside 51 other marketing files in the same bundle.

What Most SEO Practitioners Actually Do

Common pattern from teams we've worked with:

• Week 1: Install claude-seo (4.1k) + GSC MCP + a content workspace
• Week 2: Realize the three don't share methodology and produce inconsistent output
• Week 3: Try to write a unifying SEO playbook and abandon when it grows past 1,000 lines
• Week 4: Skip GEO entirely because the integration cost is too high
• Week 5: Buy ClaudeFast Growth Kit and run a full GEO audit by Friday

This is not universal, but it is common enough to be a pattern.

How to Pick

SEO with a strong existing playbook? Standalone packs work. Pick claude-seo (4.1k) for breadth or geo-seo-claude (4.8k) for GEO depth.

Need just GEO? geo-seo-claude or Auriti-Labs/geo-optimizer-skill cover it standalone.

Need integrated SEO + GEO + GSC + content production? ClaudeFast Growth Kit. The integration is the product.

Need SEO and the broader marketing system? ClaudeFast Growth Kit again. SEO is one of 10 sub-categories in the same bundle.

Need both engineering and marketing systems? ClaudeFast Complete Kit bundles ClaudeFast Code Kit and ClaudeFast Growth Kit at a discount.

What to Read Next

• Best Claude Code marketing & GTM skills for the demand-side counterpart
• Best Claude Code skills repos for the engineering layer
• AI SEO and GEO optimization guide for the GEO playbook in detail
• Best MCP servers list for the data integrations these workflows depend on
• Backlink strategy guide for the work no skill can fully automate

The fastest test for an SEO skill is whether the output would make you click. If the audit tells you generic things you already knew, throw it out. If the GEO scorer rewrites your content into something you'd be embarrassed to publish, throw it out. The advantage of an integrated 9-workflow system is that the test happens once against shared methodology, not nine times across nine disconnected tools.
