Awesome GEO
A curated list of 168 free platforms and 52 open-source repos & tools for Generative Engine Optimization (GEO) — SEO for the AI era.
Generative Engine Optimization is SEO for the AI era. As ChatGPT, Perplexity, Gemini, and AI Overviews replace traditional search, your online presence needs to be discoverable by machines — not just humans.
Semrush's 2025 study on 1,000 domains found:
Authority matters , but correlation varies by engine and metricNofollow links still matter and were close to follow links in observed impactThreshold effects matter more than naive linear authority scoringBacklink context and surface type matter more than raw link volume alone
This list helps you build that foundation — for free.

npm install
npm run validate This repo is data-first: data/sites/*.yaml and data/repos/*.yaml are the source of truth, and README.md is generated from them.
Useful commands:
npm run validate — typecheck, validate YAML data integrity, regenerate README.mdnpm run verify-all — re-check all platform entries livenpm run refresh-authority — refresh Open PageRank and Tranco metricsnpm run refresh-ai-access — refresh robots.txt crawler access signals
Environment:
OPENPAGERANK_API_KEY is required for authority verification workflows
Core signals are checked automatically. Authority is a normalized Open PageRank score, and popularity is based on Tranco rank. GEO score is a reference-likelihood model weighted toward crawl access, popularity, query fit, indexability, authority, and link value.
Representative public pages are currently seeded for 104/168 platforms. Remaining entries fall back to the platform root until a better public page is sourced.
