Your SEO agency inside the terminal

What Claude SEO is

Claude SEO is a free, MIT-licensed plugin you use directly inside Claude Code. Under the hood: 25 skills, 18 agents working in parallel, and several extensions. In practice: a mini SEO agency living in your terminal, instead of platforms like Ahrefs or Semrush.

I tried it on AI Pratika's own site (the one I run every day), and it surfaced opportunities and details I'd completely missed — and it did it in minutes. Your data stays yours: nothing gets sent to external servers, unless you turn on the paid extensions.

«The point isn't having the highest score. It's knowing, every week, which is the next move that moves the needle.»

How to install it

All you need is only Claude Code and a bit of terminal comfort. The installer puts the files in ~/.claude/, creates an isolated Python environment, and doesn't touch root permissions or your system Python.

INSTALLATION 
# macOS / Linux
git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git
bash claude-seo/install.sh

# Windows (PowerShell)
powershell -ExecutionPolicy Bypass -File claude-seo\install.ps1

You'll find everything (repo, docs, and commands) on the official site.

The commands you'll use

The pattern is always the same: /seo <command> <url>. The practical tip: start with the audit for the big picture, then drill down with the right command.

INSIDE CLAUDE CODE 
/seo audit https://iltuosito.com
  • /seo audit Full site health check, a 0–100 score with a prioritized action plan.
  • /seo page In-depth analysis of a single page.
  • /seo technical Technical audit: crawlability, indexing, Core Web Vitals.
  • /seo content Content quality and E-E-A-T.
  • /seo schema Validates and generates ready-to-paste JSON-LD structured data.
  • /seo geo Optimization for AI Search / GEO (AI Overviews, ChatGPT, Perplexity).
  • /seo backlinks Backlink analysis from free sources.
  • /seo google Connects Search Console and GA4 for real data.

How it reads your site: the health score

The audit closes with a score from 0 to 100. It's not a random number: it weighs the areas by how much they actually matter for ranking. Here's how it's made up.

Weight of each area in the score
  • Content quality 23%
  • Technical SEO 22%
  • On-page SEO 20%
  • Schema / structured data 10%
  • Performance (incl. INP) 10%
  • AI Search readiness 10%
  • Images 5%

The generated schema is ready-to-paste JSON-LD. Rerun the audit after every change to watch the score move over time.

What it does (and doesn't do)

It analyzes and tells you what to do. It doesn't do it for you. Execution stays yours.
A young site with no backlinks has authority limits that no technical fix can solve on its own.
Some extensions (DataForSEO, image generation) require paid external API keys.

Claude SEO isn't a magic wand: it's a copilot that puts the priorities in front of you. The strategic judgment and the execution stay with you — and that's exactly where you win.
