What SEO Analysis does

The SEO Analysis skill provides a robust framework for conducting in-depth SEO evaluations across various industries, including SaaS, e-commerce, local services, and publishing. It allows users to perform comprehensive audits of entire websites or analyze specific pages, ensuring that all aspects of search engine optimization are covered. With commands like /seo audit and /seo page, users can obtain detailed reports that highlight critical SEO factors such as crawlability, indexability, and performance metrics like Core Web Vitals.

This skill orchestrates a suite of 24 sub-skills and 18 sub-agents, enabling users to delve into specific areas of SEO. For instance, the /seo schema command helps detect and validate Schema.org markup, while /seo images focuses on optimizing image SEO. Users can also generate XML sitemaps with /seo sitemap and analyze backlinks using the /seo backlinks command. The skill's modular design allows for flexibility, catering to diverse SEO needs from technical audits to content quality assessments.

One of the standout features of this skill is its synthesis methodology, which organizes findings into actionable insights. It employs a structured approach that walks through phases of perception, analysis, validation, and action, ensuring that users not only receive data but also a coherent strategy for improvement. The skill culminates in a unified report that includes an SEO Health Score and a prioritized action plan, making it suitable for both individual webmasters and larger agencies.

For developers and designers seeking to enhance their SEO capabilities, this skill is an invaluable tool. It integrates seamlessly with AI coding agents, providing a comprehensive solution for optimizing websites and improving search engine visibility.

When to use it

Use this skill when you need to perform detailed SEO analysis on websites, whether for audits, content optimization, or technical assessments.

SEO: Universal SEO Analysis Skill

Invocation: /seo $1 $2 where $1 is the command and $2 is the URL or argument.

Runtime: Run bundled Python tools through claude-seo run <script.py>. Plugin installs expose this command automatically. Repository users run ./bin/claude-seo; manual installers rewrite the command to the isolated launcher path. Never invoke bundled scripts with a bare Python interpreter.

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 24 sub-skills (21 core + 1 framework integration + 2 extension mirrors) and 18 sub-agents. A separate optional Firecrawl extension is also installable (see "Optional Extensions" below).

/seo setupExplicitly create or refresh the isolated Python runtime and Chromium
/seo doctorCheck runtime readiness without changing the system

Runtime Setup

Run setup only when the user explicitly invokes /seo setup or explicitly asks to repair dependencies. Execute claude-seo setup, report core and Chromium status separately, and do not fall back to global or user package installation. For diagnosis, execute claude-seo doctor --json; its output intentionally omits absolute paths and environment values. If any claude-seo run command reports that setup is required, suggest /seo setup and do not improvise a pip install.

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 (claude-seo run 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 (claude-seo run 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. If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent
  9. If e-commerce detected, also spawn seo-ecommerce agent
  10. If drift baseline exists for this URL (claude-seo run drift_history.py <url>), also spawn seo-drift agent
  11. Always include seo-sxo in full audits (search experience applies to all sites)
  12. Collect results and generate unified report with SEO Health Score (0-100)
  13. Synthesize via the 10-principle framework (see "Synthesis Methodology" below), walk PERCEIVE → ANALYZE → VALIDATE → ACT before bucketing findings into Critical / High / Medium / Low
  14. Create prioritized action plan with dependency sequencing + falsifiability per recommendation
  15. 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.

Synthesis Methodology

Audits are not just findings, they are findings synthesized into a coherent strategy. claude-seo uses a 10-principle thinking framework grouped into four phases: PERCEIVE (observe-external · observe-internal · listen), ANALYZE (think · connect-lateral · connect-system), VALIDATE (feel · accept), ACT (create · grow).

Full audits (/seo audit, /seo page) walk every phase before emitting the action plan. Narrower commands (/seo schema, /seo images, etc.) pass at least THINK + ACCEPT before emitting (sound first principle, surfaced falsifiability). The Critical / High / Medium / Low priority buckets are the output of validation, not a substitute for it.

Full methodology + per-principle SEO mapping: references/thinking-framework.md.

Each emitted recommendation should carry:

  • The first-principle observation it rests on (THINK)
  • The dependency on / unblock relationship to other recommendations (CONNECT-system)
  • An explicit "how would we know this failed?" check (ACCEPT)
  • A leading indicator the user can monitor without re-running the audit (GROW)

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: Google retired FAQ rich results for ALL sites on May 7, 2026 (no SERP feature anymore; supersedes the Aug 2023 gov/health restriction). Flag existing FAQPage at Info (not Critical); do not claim confirmed AI/LLM citation benefit; do not recommend removal; do not recommend new FAQPage for Google SERP benefit; use QAPage for genuine user Q&A
  • All Core Web Vitals references use INP, never FID

Optional Extensions

The following ship in extensions/ rather than skills/ and require a separate installer to activate (see each extension's install.sh/install.ps1):

All optional extensions are reachable through /seo subcommands once installed: firecrawl, dataforseo, and image-gen, plus /seo ahrefs, /seo bing, /seo profound, /seo seranking, and /seo unlighthouse. Each installs as its own sub-skill, so the model also auto-routes to their descriptions without the /seo prefix.

  • seo-firecrawl -- Full-site crawling and site mapping via Firecrawl MCP. Install via extensions/firecrawl/install.sh (Unix) or extensions/firecrawl/install.ps1 (Windows). Once installed, invoke via /seo firecrawl <command>.
