Add GEO Optimizer (open-source audit + fix CLI)

[auriti]

Hey — been using this list as a reference for a while, figured I'd contribute back.

I built GEO Optimizer over the past few months as a hands-on way to apply the Princeton GEO paper findings to real sites. It started as a simple audit script and grew into a proper CLI toolkit.

What it does in a nutshell:

• Runs a full GEO audit and gives you a score out of 100 (robots.txt, llms.txt, schema, meta, content)
• Doesn't just tell you what's wrong — actually generates the fix files (robots.txt patches, llms.txt from your sitemap, missing JSON-LD schemas, meta tags)
• Has a "citability" checker that maps your content against all 9 methods from the Princeton paper (quotations, statistics, authoritative tone, etc.)
• Works as an MCP server too, so you can plug it into Claude Code or Cursor as a tool

It's fully open source (MIT), tested on Python 3.9–3.13, and on PyPI (pip install geo-optimizer-skill). No API keys, no SaaS, no signup — just a CLI.

I added it under Utilities & Generators → Open Source Data / Evals since it fits alongside the other open-source tools there.

Happy to adjust the description or placement if you think it belongs somewhere else!
