Claude SEO

Claude SEO is an open‑source skill for Claude Code that turns the chatbot into a full‑blown AI‑powered SEO engine. It lets you:

  • Run a complete site audit that covers technical SEO, content E‑E‑A‑T, on‑page signals, and core‑web‑vitals.
  • Drill down into a single page for deep content and schema analysis.
  • Validate and automatically generate Schema.org markup for pages, products, videos, and more.
  • Build or review XML sitemaps, including new programmatic sitemap generation.
  • Check and optimize for AI‑search (Geospatial Optimisation, Google AI Overviews, ChatGPT web search, etc.).
  • Plan and execute programmatic SEO and competitor comparison pages.
  • Validate and create hreflang tags for multilingual sites.

The whole skill is packaged as a single skill bundle that can be installed on any machine that has Python 3.8+ and Claude Code.

Real‑World Use Cases

1. Quick Site Health Check

Run: /seo audit https://mywebsite.com and get a concise summary:

  • Core Web Vitals (LCP, INP, CLS)
  • Broken internal links
  • Missing or deprecated schema
  • Keyword‑gap analysis

The output is JSON‑structured and can be piped into CI tools or stored in issue trackers.

2. Programmatic SEO Blueprint

If you maintain a data‑driven site (e.g., recipe aggregation), use /seo programmatic https://myrecipes.com to:

  • Detect thin content clusters
  • Suggest URL patterns
  • Auto‑generate canonical tags
  • Create internal linking suggestions

The skill even warns once you hit 30–50 location or category pages, so you can stop before hitting Google’s quality gates.

3. Competitor Comparison Page

Running /seo competitor‑pages https://mywebsite.com/competitor automatically outputs a Markdown table, embeds AggregateRating schema, and includes CTA‑optimized layout. Perfect for building “X vs Y” pages that rank on comparison‑intent queries.

4. Multilingual Sites

A simple /seo hreflang https://mywebsite.com/ validates existing tags, creates missing ones, and outputs a ready‑to‑publish sitemap snippet.

Integrations

Claude SEO can tap live data via MCP (Meta‑Cohort‑Platform) servers. With official integrations from Ahrefs, Semrush, Google Search Console, and PageSpeed Insights, the skill can pull real‑time metrics. Read more in the

MCP Integration Guide included in the repo.
