Generative Engine Optimization (GEO)
The discipline of structuring content and online presence to improve how a brand is represented and cited in responses generated by AI systems like ChatGPT, Perplexity, and Google AI Overviews.
Generative Engine Optimization (GEO) is the practice of influencing how large language models retrieve, summarize, and present information about a brand. The term originated in a 2023 research paper from Princeton, Georgia Tech, and IIT Delhi that tested optimization methods across thousands of queries and found certain techniques could meaningfully increase a source’s visibility in generated answers.
GEO vs. AEO
The terms are often used interchangeably. In common usage, AEO emphasizes being the direct answer (with roots in featured snippets and voice search), while GEO emphasizes representation across generative AI surfaces. In practice the strategies overlap heavily, and many practitioners treat them as the same discipline.
Why it matters
AI engines quote, cite, or skip your content — they do not rank it. A different optimization mindset is required: the success metrics, ranking signals, and preferred content formats are not the same as traditional search.
Core tactics
- Lead with clear, citable claims backed by data
- Structure content for extraction (headings, concise answers, schema)
- Maintain accurate, consistent business information across the web
- Earn authoritative mentions that models associate with your brand
