What is it?
Claude SEO is a plugin for Claude Code that bundles 26 sub-skills and 19 specialist agents for search engine optimization. A full site audit fans out work to multiple agents at once across technical SEO, content quality (E-E-A-T), Schema.org markup, AI search optimization (GEO/AEO), local SEO, e-commerce, and international SEO, then produces a prioritized action plan with 0-100 scores.
Commands are invoked as /seo followed by a subcommand such as audit, page, schema, geo, or local. Coverage includes Core Web Vitals (LCP, INP, CLS), JSON-LD validation and generation, llms.txt and agent-readiness checks, hreflang auditing, sitemap generation, and PDF or Markdown reports. Headless Playwright rendering handles single-page applications.
Google data is optional. A tiered credential setup connects PageSpeed Insights, CrUX, Search Console, GA4, and Keyword Planner, and optional extensions add Bing Webmaster, Profound, SE Ranking, and Unlighthouse data. Without any keys, the core audits still run.
