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).

Quick Reference

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:

• Detect business type (SaaS, local, ecommerce, publisher, agency, other)

• Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo

• If Google API credentials detected (claude-seo run google_auth.py --check), also spawn seo-google agent

• If local business detected, also spawn seo-local agent

• If local business detected AND DataForSEO MCP available, also spawn seo-maps agent

• If backlink APIs detected (claude-seo run backlinks_auth.py --check), also spawn seo-backlinks agent

• If Firecrawl MCP available, use firecrawl_map to discover all site URLs before analysis

• If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent

• If e-commerce detected, also spawn seo-ecommerce agent

• If drift baseline exists for this URL (claude-seo run drift_history.py <url>), also spawn seo-drift agent

• Always include seo-sxo in full audits (search experience applies to all sites)

• Collect results and generate unified report with SEO Health Score (0-100)

• Synthesize via the 10-principle framework (see "Synthesis Methodology" below), walk PERCEIVE → ANALYZE → VALIDATE → ACT before bucketing findings into Critical / High / Medium / Low

• Create prioritized action plan with dependency sequencing + falsifiability per recommendation

• 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

Scoring Methodology

SEO Health Score (0-100)

Weighted aggregate of all categories:

Priority Levels

• High: Significantly impacts rankings (fix within 1 week)

• Medium: Optimization opportunity (fix within 1 month)

• Low: Nice to have (backlog)

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>.

• seo-performance -- Core Web Vitals measurement

• seo-visual -- Screenshots, mobile testing, above-fold
