AEO, GEO & AI search explained
If you've heard the terms 'AEO' and 'GEO' thrown around and quietly nodded along, this page is for you. We'll build the whole idea from scratch — no jargon assumed.
The shift: from links to answers
For twenty-five years, finding something online meant the same ritual: type a query into a search box, get a page of blue links, and click through to read. The job of a business was to rank as high as possible on that list. That discipline has a name — SEO, or Search Engine Optimization.
Something changed. When you ask ChatGPT “what’s the best project management tool for a small design studio?”, it doesn’t hand you ten links to sort through. It gives you an answer — a few paragraphs that name specific products, explain trade-offs, and maybe link to a handful of sources. Google now does the same thing at the top of its results with AI Overviews. The list of links didn’t just get reordered; for many questions, it got replaced by a single synthesized response.
This matters enormously for any business, because the answer is where the decision now happens. If the AI names three tools and yours isn’t one of them, you were never in the running — the user never saw a link to click. You didn’t rank low. You were simply absent.
The one-sentence version
Search used to be about ranking on a list of links. AI search is about being named inside the answer. Those are different games, and they need different tools.
What is an “answer engine”?
The tools that generate these responses have a collective name.
Answer engine
Any system that responds to a question with a written answer instead of a list of links. ChatGPT, Google’s AI Overviews, Perplexity, Microsoft Copilot, and Gemini are all answer engines. They read across many sources, then compose a single response — often mentioning brands and products by name and citing a few pages as backup.
OptimizeCamp tracks two answer engines today — ChatGPT and Google AI Overviews — with more added over time. See Answer engines we track.
Because answer engines are powered by large language models (the same technology behind generative AI), the whole category is sometimes called generative search or AI search. You can treat “answer engine,” “generative search,” and “AI search” as the same thing.
AEO — Answer Engine Optimization
Once answer engines matter, a natural question follows: how do I make sure they mention me? The practice of doing that has a name.
AEO
Answer Engine OptimizationThe practice of making your brand and content more likely to be named, recommended, and cited by answer engines. Where SEO optimizes for a rank on a list, AEO optimizes for presence inside a generated answer.
GEO — Generative Engine Optimization
You’ll also see the term GEO. It describes the same goal from the angle of the technology doing the answering.
GEO
Generative Engine OptimizationOptimizing your content for generative engines — AI systems that generate answers rather than retrieve links. In practice, GEO and AEO are used interchangeably: both mean “get picked by the AI.” If there’s a shade of difference, GEO leans toward the mechanics of the AI models, and AEO leans toward the user-facing outcome of being the answer.
Note
Don’t get hung up on AEO versus GEO. The industry hasn’t fully settled the vocabulary, and different vendors use them slightly differently. Throughout these docs we’ll usually say AI visibility — the plain-English umbrella for “how present and well-regarded you are inside AI answers.”
How this compares to SEO
AEO doesn’t replace SEO — good content and a healthy site help both. But the target, the unit of success, and the feedback loop are different.
| Classic SEO | AEO / GEO | |
|---|---|---|
| You optimize for | A rank on a page of links | Being named inside an answer |
| Success looks like | Position #1 for a keyword | Recommended, cited, spoken of well |
| The user sees | Ten links; they choose | One answer; the AI chose |
| You measure with | Rank trackers, Search Console | An AI visibility platform |
That last row is the gap OptimizeCamp fills. Your rank tracker cannot tell you whether ChatGPT recommends you, because there is no ranking — there is an answer, and it changes with every question, model, and day.
How an answer engine decides what to say
You can’t optimize what you don’t understand, so here’s the mechanism in four steps — simplified, but accurate enough to reason about.
It interprets the question
The model reads the user’s prompt and works out intent — are they comparing options, looking for a how-to, checking a fact?
It gathers material
Modern answer engines search the live web for relevant pages, and also draw on what the model already “knows” from training. This is why the content on your site — and your competitors’ sites — feeds directly into the answer.
It composes an answer
The model synthesizes what it gathered into a single response, deciding which brands to name, in what order, and how to characterize each one.
It cites some sources
Many answers link to a few pages the model leaned on. Being one of those cited sources is a strong, durable form of visibility — and one you can influence directly with your content.
Notice that three separate things can happen to your brand in that answer: you can be mentioned in the text, you can be cited as a linked source, and you can be spoken about with positive, neutral, or negative sentiment. These are distinct, and OptimizeCamp measures each one. The next concept page, Mentions, citations & share of voice, unpacks them in detail.
Where OptimizeCamp fits
Knowing the theory is one thing; doing something about it is another. Most tools help with only one half — they either tell you you’re invisible (trackers) or help you write content without knowing what to write (AI writers). OptimizeCamp closes the loop between them:
Measure
Monitor your visibility
Track how AI answers name, cite, and describe you across the prompts that matter.
Fix
Optimize existing pages
Repair the pages that should be cited but aren't, worst-first.
Create
Generate missing content
Build pages for the questions where competitors win and you have nothing.
Prove
Prove the impact
Re-measure after each change and see the citations you gained.
Key takeaways
- AI search replaces a list of links with a single generated answer — the decision now happens inside that answer.
- AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) both mean getting picked by the AI; we call it AI visibility.
- Your brand can be mentioned, cited, and characterized with a sentiment — three distinct things worth measuring.
- OptimizeCamp measures your AI visibility and then helps you act on it, closing the loop that point tools leave open.
