Claude Skill for SEO

The /seo skill is the master orchestrator that routes 25 specialist sub-skills covering technical SEO, content quality, schema validation, GEO/AI search readiness, local optimization, and backlink analysis, all from one command in Claude Code.

What the /seo skill actually is?

An orchestrator, not a single checker

The /seo skill is the command surface that sits in front of 25 specialist sub-skills. When you type /seo audit, it parses your URL, detects the site type (SaaS, local, e-commerce, publisher, or agency), and routes you to the right combination of specialists: technical checks, content quality, schema validation, image analysis, backlinks, local signals, and AI search readiness.

Every audit produces a 0-100 SEO health score weighted across seven categories: Technical SEO (22%), Content Quality (23%), On-Page SEO (20%), Schema Markup (10%), Core Web Vitals (10%), AI Search Readiness (10%), and Image Optimization (5%). Findings bucket into Critical, High, Medium, and Low tiers with actionable recommendations.

It applies the PERCEIVE-ANALYZE-VALIDATE-ACT synthesis framework to every recommendation: each finding carries the founding observation, dependency relationships, a falsifiability check, and leading indicators to monitor. No vague advice, only implementable actions with measurable outcomes.

When it Triggers?

The skill routes to different specialists based on the subcommand: /seo audit for full site crawl, /seo page for single-page deep analysis, /seo technical for crawlability and Core Web Vitals, /seo content for E-E-A-T evaluation, /seo schema for structured data validation, /seo geo for AI search readiness, and /seo local for Google Business Profile signals.

Additional subcommands include /seo images, /seo backlinks, /seo ecommerce, /seo sitemap, /seo plan, /seo flow, /seo hreflang, /seo drift, /seo programmatic, /seo sxo, /seo maps, /seo google, and /seo dataforseo. Run /seo without a subcommand to see the full menu.

What the suite delivers

25 specialist skills, one command surface

01

Full site crawl

Crawls up to 500 pages, detects site type, and delegates to 15 specialist subagents in parallel. Produces a 0-100 health score with Critical-to-Low issue tiers and a two-document report package.

02

Specialist routing

Routes requests to the right sub-skill based on the subcommand: technical, content, schema, geo, local, backlinks, ecommerce, images, sitemap, plan, flow, hreflang, drift, and more.

03

PERCEIVE-ANALYZE-VALIDATE-ACT

Every recommendation follows this four-phase synthesis framework: founding observation, dependency relationships, falsifiability checks, and leading indicators for monitoring.

04

Markdown report output

Delivers two markdown files on every full audit: a comprehensive findings report and a prioritized action plan sorted by impact and implementation effort.

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

The /seo skill parses your subcommand and URL, detects your site type, and routes to the appropriate specialist sub-skill or combination. Each subcommand maps to a specific agent with defined scoring and output.
The score weights seven categories: Technical SEO (22%), Content Quality (23%), On-Page SEO (20%), Schema Markup (10%), Core Web Vitals (10%), AI Search Readiness (10%), and Image Optimization (5%). Each specialist agent scores its category independently.
Main subcommands: audit, page, technical, content, schema, geo, local, backlinks, ecommerce, images, sitemap, plan, flow, hreflang, drift, programmatic, sxo, maps, google, dataforseo, and image-gen. Run /seo without a subcommand to see the full menu.
Most checks run on Claude Code alone. Optional integrations (DataForSEO for live SERP data, Google Search Console, Moz for backlinks) unlock richer signals but are not required. Each skill falls back gracefully.
The /seo skill runs inside your terminal and codebase, not a cloud dashboard. It applies AI reasoning to prioritize findings for your specific site type and covers both traditional Google SEO and AI search citation signals in one pass.
Every recommendation includes: the founding observation, dependency relationships (what else this affects), a falsifiability check (how you would know the fix worked), and leading indicators to monitor after implementation.
