Best Claude Skills for SEO (2026)
Most "best skills" lists are copied README summaries. This one isn't: we installed all 35 seo skills in our catalog, ran each against a baseline and scored four criteria. 13 passed cleanly, average score 8.6/10. The one to start with: SEO Audit.
Ranked by SkillProof Score · how we score
- 1
SEO Audit
Structured technical/on-page/content SEO audit that explicitly flags a real trap: static fetch tools can't see JS-injected schema markup.
From our test: Best concrete finding: the skill catches a real false-positive trap before you make it -- it explicitly warns that web_fetch/curl strip client-side-injected JSON-LD, so 'no schema found' from a raw…
- 2
Programmatic SEO
12-playbook framework for templated pages at scale (locations, comparisons, integrations, glossary...) with an explicit thin-content guardrail checklist.
From our test: A baseline pass on the mini-task ('one page per job title, swap the title in the H1') walks straight into the exact anti-pattern the skill names as mistake #1 in its own Common Mistakes list -- the…
- 3
Schema Markup
JSON-LD generator/validator for schema.org rich-results markup.
From our test: Asked for schema on a SaaS pricing page: the skill combined Organization + SoftwareApplication + FAQPage under one @graph block using the correct required properties (name+offers for…
- 4
AI SEO
GEO: AI-crawler access checks, extractable content structure, citation tracking.
From our test: Ran a citability check for a SaaS 'X vs Y' comparison page: it named the exact bots to check for (GPTBot, PerplexityBot, ClaudeBot, Google-Extended) and cited the '~33% of AI citations go to…
- 5
Hitkeep AI Visibility Analyst
Turns HitKeep MCP data into honest verdicts on which AI bots actually send traffic.
From our test: Ran a synthetic fetch-vs-visit scenario (GPTBot 340 fetches/2 visits vs ClaudeBot 12 fetches/45 visits) through the skill's interpretation rules — it caught the classic mistake of attributing…
- 6
Super GEO Agent Readiness
GEO/AEO audit router: content, schema, llms.txt, and agent-readiness checklists.
From our test: Fed it a promo-speak paragraph ('unlock the power', 'unleash your team's potential') and the skill's own audit checklist flagged those exact banned phrases plus missing author credentials, JSON-LD…
- 7
SEO & LLMO
Pre-launch SEO, structured data, and AI-agent-readiness checklist (llms.txt, robots.txt, JSON-LD).
From our test: Skill-guided pre-launch package added llms.txt, agent.json, an A2A agent-card.json, and the 2025 Content-Signal robots.txt directive that a baseline (unguided) pass skipped entirely — genuinely…
- 8
GEO Visibility
Passage-level citability rules and a sourced 5-pillar 0-100 score for getting cited by AI engines.
From our test: Audited a deliberately weak sample passage twice: baseline gave generic on-page SEO tips (keywords, meta description, backlinks); the skill instead cited the exact rule broken ('As mentioned above'…
- 9
Ultimate SEO + GEO
27-script SEO/GEO audit agent covering technical health, E-E-A-T, schema, and AI-search citation.
From our test: Pulled Anthropic's live robots.txt and applied the skill's AI-crawler taxonomy (OAI-SearchBot vs GPTBot, Google-Extended vs Googlebot) — a distinction a generic audit pass misses — and confirmed all…
- 10
Compress Images
Iterative cwebp loop that lands every image under a 100KB web/SEO target
From our test: Real A/B on a worst-case 3.1MB noise-heavy synthetic JPG: a naive single-pass `cwebp -q 80` (my baseline) left it at 1.7MB, 17x over the stated 100KB target, while following the skill's iterative…
How this ranking works
Each skill gets a fresh install in Claude Code, three trigger phrasings, and the same task run with and without it. Scores: installation (5), trigger reliability (5), output vs baseline (10), documentation honesty (5) — normalized to a 10-point SkillProof Score. Full rubric on the methodology page. Queue-verdict skills sit at the bottom until testing completes.
