Generative engine optimisation (GEO): The practice of shaping content so that AI answer engines such as ChatGPT, Claude and Grok are more likely to find it, use it and cite it in their answers.
The term comes from a 2023 paper by Pranjal Aggarwal and colleagues, later accepted at KDD 2024, which reported that some content changes raised visibility in generated answers by up to 40%, with results varying by subject. Some people call the same work answer engine optimisation.
