LLM optimization (LLMO) means making your business easy for large language models, the technology behind ChatGPT, Gemini and Perplexity, to understand, describe accurately and recommend. In practice it is closely related to generative engine optimization (GEO) and builds on SEO.

LLMO, GEO and AEO: one family
The industry uses several names for overlapping work. LLMO focuses on the models themselves, GEO on the generative answer engines built from them, and AEO on being the quoted answer. For a business owner the practical goal is the same: be named, be described correctly, and be chosen.
What makes a brand easy for an LLM to name
| Trait | Why it matters |
|---|---|
| Specific | A clear description of services and places gives the model a sentence it can repeat |
| Consistent | Matching facts across the web leave no contradictions to resolve |
| Evidenced | Named experts, sources and reviews make claims attributable |
| Accessible | Pages that can be crawled and read are pages that can be learned from and cited |
Demand
In Google Keyword Planner (United States, retrieved 25 October 2026), "llm optimization" shows 100 to 1,000 monthly searches with Low advertiser competition.
Our expert view
We are cautious with anyone selling secret prompts or tricks for language models. Models change often; durable visibility comes from being a genuinely clear, well-documented and well-reviewed business. That is the foundation we build. See what generative engine optimization is.
