The most installed Claude skills for SEO audits, schema, site structure and AI search, plus claude-seo for full site audits.

Picks

ranked

The most installed Claude skills for SEO are seo-audit, ai-seo and programmatic-seo from Corey Haines's free Marketing Skills pack. For a full technical audit of a live site, Daniel Agrici's claude-seo plugin runs dozens of checks behind one /seo audit command.

The one thing to know first: these skills read and advise, they do not see your rankings. For real traffic and keyword data, connect Search Console or use a skill that reads it, such as Ian Nuttall's seo.

The two packs cover different jobs. Marketing Skills helps you plan and write pages that rank: audits, site structure, schema markup, comparison pages, pages built at scale and content that AI answers cite. Every skill in it first reads a product-marketing file, so describe your product once and the advice gets specific.

claude-seo is built for Claude Code. It bundles 26 sub-skills and 19 agents, needs Python 3.11 or newer, and installs a headless browser during /seo setup. It needs no API keys to start; free Google APIs such as PageSpeed Insights and Search Console are optional.

Good for

  • Site owners who want an SEO audit without a paid tool
  • Content marketers planning pages that rank and get cited by AI
  • Developers fixing titles, schema and metadata in code
  • SEO consultants running the same checks for every client
