INSTALL CLAUDE SEO.
One command. Free, open-source under MIT. Runs entirely on your machine through Claude Code. No SaaS, no signup, no rate limits, no credit card. 4,900+ GitHub stars and counting.
After install, open Claude Code and type /seo audit https://your-site.com to run your first audit. 18 subagents work in parallel.
3 things you need.
If you have these, you are 2 minutes from your first audit.
// CLAUDE CODE
The CLI from Anthropic. Get it at claude.com/claude-code. Free with any Claude plan.
// PYTHON 3.10+
Check with python3 --version. Most modern systems already have it. Download Python.
// GIT
Check with git --version. Install Git if missing.
Clone. Install. Audit.
If anything fails, the installer prints the exact fix. Most issues come from missing Python or Git.
Plugin marketplace (Claude Code 1.0.33+)
/plugin marketplace add AgriciDaniel/claude-seo
/plugin install claude-seo@AgriciDaniel-claude-seo
Two commands inside Claude Code. Marketplace handles updates automatically. Falls back to git clone for older Claude Code versions.
Clone the repo (alternative)
git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git
Shallow clone keeps download under 5 MB. Use this path if you want to fork, contribute, or run a pinned version.
Run the installer (manual path only)
macOS / Linux: bash claude-seo/install.sh
Windows: powershell -ExecutionPolicy Bypass -File claude-seo\install.ps1
Installer copies skills to your Claude Code skills directory and writes the slash commands. Idempotent: re-run any time. Marketplace install handles this automatically.
Run your first audit
Open Claude Code: claude
Run: /seo audit https://your-site.com
Up to 18 AI agents analyze your site in parallel. Output is a 0-100 health score plus a prioritized action plan. Typical run: 8-12 minutes.
