# AEO vs GEO

AEO vs GEO explained: why the terms are often used interchangeably, where they differ in practice, and how on-page and off-site AI visibility work fit.

Glossary comparison

## AEO vs GEO

AEO and GEO overlap so heavily that many people use the terms interchangeably. Where a line is drawn, AEO is about structuring content so a system can extract a direct answer, while GEO is the wider job of getting AI systems to mention a brand, cite it and describe it accurately.

## AEO and GEO compared

|  | AEO | GEO |
| --- | --- | --- |
| Core question | Can a system lift a clean answer from this page? | Is the brand named, cited and described correctly? |
| Roots | Featured snippets and voice assistants | A 2023 research paper on generative search engines |
| Scope | Page structure and answer wording | Brand presence across the web |
| Typical work | Question headings, direct answers, lists and tables | Third-party coverage, consistent facts, citation tracking |
| Sources in play | Mainly your own pages | Your pages plus reviews, press and forums |
| How it is measured | Featured snippets, People Also Ask, answer usage | Mention rate, citation rate, AI share of voice |
| Relationship | Most AEO tactics are also GEO tactics | GEO includes AEO plus off-site work |

## Are AEO and GEO the same thing?

Mostly, yes. Both aim to be the source an AI assistant or search engine uses when it answers a question, both rely on the same crawlable, indexed pages, and many tools and agencies sell the same service under either name. AEO is the older label, tied to featured snippets and voice search. GEO comes from a 2023 paper by researchers at Princeton and elsewhere that studied visibility inside answers written by large language models.

Arguing over the label is rarely useful. Agreeing which platforms, prompts and metrics count is.

## Where they differ in practice

The difference shows up in what an audit looks at. An AEO review works page by page: does each page put the question in a heading, answer it in the first sentence or two and keep that answer self-contained? A GEO review starts from the AI answers themselves: which brands are named, which sources are cited, which competitors appear and whether the description of the business is right.

A page can be perfectly structured and still be left out if the answer draws on review sites and press coverage instead. Fixing that is GEO work that AEO, in its narrower sense, does not cover.

## How to use them together

Google says no special markup makes a page eligible for featured snippets, AI Overviews or AI Mode, so the page-level work is about clarity rather than code. Treat AEO as the on-page layer of a GEO programme: structure answers well, then work on the sources and mentions that decide whether the brand is included at all.

## Example

An accounting software firm rewrites its help pages so each opens with a one-sentence answer, and some start appearing as featured snippets. That is AEO. When ChatGPT is asked which accounting tools suit sole traders, the firm is still missing, because the answer relies on three comparison sites that do not list it. Getting onto those sites is GEO.
