What LLMO means
LLMO is large language model optimization: making a website that language models can retrieve, afford to read, and use correctly. It is the newest of four acronyms competing to name the same activity, and it arrived because the earlier ones were already attached to somebody’s product.
| Acronym | Stands for | What it emphasises |
|---|---|---|
| LLMO | Large language model optimization | The model as the reader |
| GEO | Generative engine optimization | The generated output |
| AEO | Answer engine optimization | Being the source of an answer |
| LLM SEO | LLM search engine optimization | The continuity with SEO |
They prescribe the same fixes in the same order. If a proposal treats them as four workstreams with four budgets, that is a pricing decision wearing a taxonomy costume.
The job all four names describe
Four requirements, in order, because a failure early makes everything after it irrelevant. Most sites fail one of the first two and have never been told.
- The fetch is allowed. A
robots.txtline or a CDN bot rule ends it silently, with no error logged on your side. - The response parses without a browser. Facts that appear only after JavaScript runs are absent from what the model receives.
- The facts are cheap to reach. Models read under a token budget, so a first fact buried behind markup may be dropped for a shorter source.
- The facts agree with themselves. When your prose and your structured data differ, the model picks one and you do not choose which.
The measured effect of fixing the third is on the record twice, and the two captures are quoted separately because a product page and a services page carry different amounts of chrome. A product page went from 91,226 bytes to 1,315; a services page from 13,581 to 1,412. The facts were unchanged in both.
Which page you actually want
Rather than restate the method four times under four names, here is the routing. Each of these covers the same underlying work from the angle its readers arrive with.
- You want the method, in depth. LLM optimization has the token arithmetic and the serving change.
- You already do SEO. LLM SEO covers what transfers, what stops counting, and what to stop doing.
- You are comparing GEO to SEO. GEO vs SEO takes that comparison apart properly.
- You want the definition of AEO. What is AEO does the same job this page does, for that acronym.
- You just want to know if you have a problem. Scan a URL. Free, no account, about a minute.
