Claude SEO: SEO Skill for Claude Code

Claude SEO is an open-source SEO analysis plugin for Claude Code. It runs 26 sub-skills and 19 specialist agents in parallel across technical SEO, content quality (E-E-A-T), Schema.org markup, AI search optimization (GEO), local SEO, e-commerce, and international SEO. Every audit produces a prioritized action plan with testable recommendations grounded in primary-source guidance from Google.

Two versions of this skill.

• 🌐 Public open-source → AgriciDaniel/claude-seo: MIT, public releases, no membership. Use this if you want stable + downloadable.
• 🔒 Community private mirror → AI-Marketing-Hub/claude-seo: early access to upcoming features and direct collaboration with the AI Marketing Hub Pro community. Requires membership.

Why Claude SEO

• AI-search first. Aligned with Google's AI Optimization Guide. Question-based citability scoring, primary-source evidence on llms.txt, IPTC TrainedAlgorithmicMedia for AI-generated product images, agent-friendly page checks per web.dev, and /seo agentic for agent readiness scored the way Lighthouse's Agentic Browsing category counts it.
• Parallel execution. Full site audits spawn up to 17 specialist agents simultaneously. Site-level audits complete in minutes rather than hours.
• Falsifiable, not promotional. Every recommendation carries the first-principle observation it rests on, its dependency relationships, an explicit "how would we know this failed?" check, and a leading indicator. See Methodology.

Real results

Who this is for

• SEO agencies running 5+ client sites. Replace quarterly deep audits with weekly automated runs. Same team capacity, 4× audit cadence, every recommendation comes with a falsifiability check the client can verify.
• In-house SEO leads at SaaS / publisher / e-commerce companies. Second-pair-of-eyes before executive reviews. Catches what GSC and Lighthouse hide: schema deprecation, AI-citability gaps, expired-domain heritage risk, parasite-SEO exposure, machine-translation drift.
• Freelance SEO consultants. Anchor day-one client scope with a 15-minute audit and a real 0-100 score. Win the engagement with concrete proof of value before you spend an hour writing the proposal.
