Top 5 SEO Skill Repos for AI Agents
Open-source skill packs for Claude Code and other coding agents that automate technical SEO, GEO, and search-visibility audits.
Technical SEO is one of the more mechanical parts of marketing work — crawl checks, schema validation, sitemap audits — which makes it a natural fit for an agent skill instead of a person running through a checklist by hand. The repos below split roughly into two groups. marketingskills and claude-seo are the general-purpose ones: the former treats SEO as one discipline inside a wider marketing pack, the latter is built specifically around SEO with 25 sub-skills and 18 sub-agents covering different parts of an audit. The other three lean into GEO and AEO — optimizing for AI Overviews, ChatGPT, and other answer engines rather than classic blue-link rankings. geo-seo-claude is explicit about that framing, gtm-engineer-skills is aimed at making a site findable inside AI-generated answers specifically, and Agentic-SEO-Skill is built for an LLM to run the analysis itself rather than just assist a human running it. Which one fits depends on what you're actually auditing: a full-site technical crawl points toward claude-seo, an existing site trying to show up in AI answers points toward the GEO/AEO-focused three. Star counts below are a GitHub snapshot as of the date listed, not a ranking of skill quality — read the repo before pointing an agent at your production site.

FAQ
What's the difference between classic SEO skills and GEO/AEO-focused ones?
claude-seo and marketingskills audit the things classic SEO cares about — crawlability, schema, sitemaps. geo-seo-claude, gtm-engineer-skills, and Agentic-SEO-Skill are built around showing up inside AI Overviews, ChatGPT, and other answer engines instead.
Which skill should I use for a full technical SEO audit?
claude-seo is the closest fit — it's built specifically around SEO with 25 sub-skills and 18 sub-agents covering different parts of an audit, versus the GEO/AEO-focused three which assume the technical basics are already handled.
Are any of these skills open source?
Yes — all five are public GitHub repositories, and the star counts above come straight from GitHub. Check each repo's license before using it against a production site.
