# best-aeo-skill > The research-backed, evidence-first GEO/AEO Claude skill. The complete rule book of AI search optimization. Audits, fixes, and monitors website visibility across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. MIT licensed. Built on the peer-reviewed Princeton KDD 2024 paper. best-aeo-skill is an open-source Claude Code skill that helps websites become visible and citable by generative AI search engines. It computes a 0–100 composite GEO Score across four vectors (Technical 20%, Citability 35%, Schema 20%, Entity 25%), backed by 33 evidence collectors and 100 numbered optimization rules. Findings are confidence-labeled (Confirmed / Likely / Hypothesis) so users never act on hallucinated issues. ## Primary pages - [Home — overview, install, FAQ](https://bestaeoskill.com/): Hero, key statistics, the three Princeton-validated signals, what's inside the skill, how it works, who it's built for, install command, research foundation, FAQ. - [The Skill — full SKILL.md](https://bestaeoskill.com/skill/): The complete rule book — architecture, 7 sub-skills, 5 specialist agents, 33 evidence collectors, 4 scoring frameworks, 100 numbered optimization rules organized in 6 categories (AI Crawler Access, Content Citability, Structured Data, Entity & Brand, Multi-engine, Anti-patterns), confidence rubric, CLI reference. - [The Ultimate Guide to GEO & AEO](https://bestaeoskill.com/guide/): 11 chapters covering AI search mechanics, technical foundations, content citability, structured data, entity signals, multi-engine optimization, measurement, common pitfalls, and a 30-day action plan. ~4,400 words plus a 25-term glossary. - [Research Foundation](https://bestaeoskill.com/research/): Deep-dive into the peer-reviewed Princeton KDD 2024 paper on Generative Engine Optimization (Aggarwal et al., arXiv:2311.09735).
