- Generative Engine Optimization
The practice of structuring web content so generative AI engines (ChatGPT, Perplexity, Claude, Gemini) preferentially cite it when answering user queries. Distinct from traditional SEO, which optimizes for ranked links rather than cited passages.
- Citation (in AI search)
A reference to an external source in an AI-generated answer. Citations may be inline hyperlinks, footnotes, or a sources panel. Engines vary in how they expose citations and which sources they prefer.
