1. What is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) is the systematic process of designing website content, data models, and semantic entities so AI-powered search engines can accurately extract, synthesize, and cite your brand as an authoritative source in AI answers.
2. Key Ranking & Citation Factors (Princeton University Research)
A seminal study from Princeton University researchers (KDD 2024) evaluated visibility optimization across generative search engines (Perplexity, Google AI Overviews, ChatGPT). The findings revealed distinct citation multipliers:
