## Definition & overview

LLM SEO is an industry label for work aimed at helping a brand or its content be discovered and represented accurately in language-model-based answers. Usage varies and often overlaps with AEO and GEO.

## Analogy & mental model

It extends your visibility work from lists of links to answers that discuss your business.

Define which engines, queries and outcomes you measure before claiming an improvement.

## Why it matters

The label is useful only if the intended outcome is defined. A brand mention, a source citation and an inbound lead require different measurements. Clear scope prevents optimisation work from becoming a collection of untested claims about what models supposedly prefer.

## Practical business example

A consultancy checks whether answers about a specific implementation problem cite its detailed guide, then looks for relevant visits rather than reporting every mention as a success.

Illustrative scenario, not a client case study or promised result.

## How it works

1. Choose engines and questions relevant to the customer’s buying journey.

2. Improve factual clarity, source accessibility and corroborating information.

3. Track a consistent sample of answers and inspect actual linked pages and referrals.

## Core components

- Defined engine and prompt set

- Content and entity accuracy

- Observed visibility outcomes

Search-only performance reports do not establish visibility inside every language-model product.

## LLM SEO vs GEO

LLM SEO and GEO are overlapping industry labels. Neither describes a universally standardised ranking system or guarantees that a model will select a page.
