Add GeoScore — free open-source GEO + SEO audit tool

[sprawf]

Adding GeoScore to the Open Source Data / Evals section.

What it is: A free, open-source instant GEO + SEO audit tool that checks 39 signals for AI search visibility — the signals ChatGPT, Perplexity, and Gemini use to decide which sites to cite.

GEO checks include:

• E-E-A-T markers (author pages, expertise signals)
• • FAQ / HowTo / Article schema
• • llms.txt support
• • Citation-friendly content patterns
• • Structured data completeness
    Why it fits here:
• Purpose-built for GEO auditing (not a general SEO tool)
• • Free and open source (MIT, GitHub: https://github.com/sprawf/geoscore)
• • No login, no tracking, no account needed
• • Built on Cloudflare Workers (stateless, $0/month to self-host)
• • Results in ~30 seconds
