Generative Engine Optimization
The practice of improving how often and how accurately a brand's content is retrieved, cited and represented in AI-generated answers.
GEO AILLMOAI SEO
LLM Optimization
A loosely used umbrella term for making a brand and its content well-represented in large language model outputs, whether from retrieval or from training data.
In full
The term overlaps heavily with GEO and AEO and is used inconsistently across the industry. Where it adds a distinct idea, it is the recognition that models have two paths to knowing about you: parametric knowledge baked in at training time, which you influence only slowly through broad web presence, and retrieval at query time, which you influence like classic SEO. Neither path is controllable in the way rankings are, which is why the discipline centres on measurement and corroboration rather than direct optimisation.
Example
A brand finds an assistant describes its pricing from an outdated third-party article, and works to correct the source rather than its own site.
