| GEO | Generative AI as the platform | Academic research, technical contexts |
| LLM SEO | The underlying model technology | Technical teams, developers |
When Each Term is Used
AI SEO
"AI SEO" is the most accessible term. It draws an explicit connection to traditional SEO while highlighting the AI angle. Marketing teams and business stakeholders often prefer this term because it's intuitive.
AEO (Answer Engine Optimization)
"AEO" emphasizes the fundamental shift from "search engines" to "answer engines." It's popular among SEO professionals who want to distinguish this practice from traditional keyword optimization. The term highlights that we're optimizing for answers, not rankings.
GEO (Generative Engine Optimization)
"GEO" emerged from academic research and emphasizes the generative nature of modern AI. It's often used in technical papers and by teams focused on the technology itself rather than the marketing application.
LLM SEO
"LLM SEO" is the most technically precise term, explicitly referencing large language models. Developer-focused teams and those building AI-adjacent products often prefer this terminology.
A Unifying Mental Model
Regardless of terminology, the core questions are the same:
- Discovery: When users ask AI assistants questions relevant to your business, does your brand appear?
- Measurement: How do you systematically track this visibility?
- Improvement: What content and strategies increase your chances of being cited?
The fundamentals of AI SEO and AEO principles apply regardless of which term you use.
