What do you need to install Claude SEO?

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.

How do you install and run Claude SEO?

If anything fails, the installer prints the exact fix. Most issues come from missing Python or Git.

1. // STEP 01 (RECOMMENDED)

   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.

2. // STEP 01 (MANUAL)

   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.

3. // STEP 02

   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.

4. // STEP 03

   Run your first audit

   Open Claude Code: claude

   Run: /seo audit https://your-site.com

   Up to 15 specialists analyze the site, depending on the detected workflow. Output includes an evidence-backed report, a heuristic 0-100 health score, and a prioritized action plan. Runtime depends on site size and enabled checks.

What should you do after your first audit?

Three places to go once your install works.
