What Is GEO? Generative Engine Optimisation, and Why AI Names Some Businesses and Not Others
GEO — Generative Engine Optimisation — is the set of practices that make your brand, your content and your details legible to ChatGPT, Google’s AI Overviews, Gemini and Perplexity, credible enough to be trusted, and clear enough to be quoted. As fewer people work their way down a page of blue links, and more simply ask which firm in Sydney is any good at managing Google reviews, whether an AI says your name has become the question that decides whether you are seen at all.
What GEO actually is
Traditional search hands you a list and leaves the sorting to you. A generative engine does the sorting itself: it reaches a conclusion on the user’s behalf and cites only the few sources it trusts enough to stand behind. GEO is the work of turning your site into one of those few — clear structure, definite facts, the answer stated before the explanation, and an entity a machine can verify.
Put at its shortest: SEO competes for a ranking, GEO competes to be named. One wins you a position in a list. The other wins you a sentence in somebody’s answer, which is where a growing share of buying decisions now start and finish.
GEO, SEO and AEO side by side
The three are layers, not alternatives.
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank high in results | Win the featured answer | Be quoted by generative AI |
| Surface | Google blue links | Q&A and voice search | ChatGPT · Gemini · AI Overviews |
| Built on | Keywords and links | Structured Q&A | Credible entity and quotable facts |
GEO is best understood as AEO carried into the generative era, which is why the two names get used interchangeably. The distinction worth keeping is emphasis: GEO cares specifically about being treated as a source, not merely about being displayed.
Why Australian businesses should start now
Three reasons, and none of them will hold for long.
- Habits are shifting. More customers ask an AI outright rather than searching and filtering, and they act on the answer they get.
- An AI cites few sources. Miss that short list and, as far as the AI world is concerned, you are not trading.
- Early is cheap. Few local businesses are doing this work yet, so holding the ground costs a fraction of what taking it back will.
None of this is mysticism. It is content and structure done deliberately, so that when somebody asks a machine who does your kind of work, the machine has something of yours worth repeating.
Frequently asked questions
What is GEO in plain terms?
Generative Engine Optimisation: the work of making your brand and content something ChatGPT, Google’s AI Overviews, Gemini and Perplexity can read, trust and quote. Traditional search hands over a list of links for you to sort through. A generative engine reaches the conclusion for the user and cites only the few sources it trusts. GEO is about being one of those few.
Are GEO and AEO the same thing?
They overlap heavily. AEO — answer engine optimisation — is about being taken up as a featured or spoken answer by a search engine. GEO refers specifically to being quoted by generative tools such as ChatGPT and Gemini. The practices are largely shared; GEO is the more precise name for the AI era.
How is GEO different from SEO?
SEO competes for a position in a list of results, using keywords and links. GEO competes to be the source an AI names, using a credible entity and quotable facts. They are not alternatives — an AI usually quotes pages that search engines already rank and trust, so GEO sits on top of solid SEO rather than replacing it.
Why should an Australian business start on GEO now?
Because customer habits are moving and the position is still cheap. More people ask an AI directly instead of searching and filtering, an AI only cites a handful of sources, and comparatively few local businesses are doing this work yet. Being early costs far less than catching up will.
How long does GEO take to show results?
Similar to SEO — weeks to months, depending on content quality, how established your entity is, and how often the engines re-crawl. The earlier the groundwork is laid, the earlier an AI starts remembering you.
What is AEO, exactly?
Work that gets ChatGPT, Perplexity and Google’s AI answers to cite you directly. It runs on question-and-answer content, structured data and trust signals (E-E-A-T).
What is structured data?
A machine-readable way of stating who you are, what you do, where you are and how you are regarded — so Google’s rich results and AI tools describe you accurately instead of guessing.
What is the difference between SEO and AEO?
SEO competes for a position in the results. AEO competes to be the source an AI quotes. Run both and you rank and get cited.
How do I judge whether it worked?
By search visibility, AI citations and enquiries that actually arrive — not by performance scores. A tidy report that brings nobody through the door has measured nothing.
Roughly what does this cost?
It depends on whether content, SEO and AEO are inside the quote. Melmel does design and build with AEO and AI SEO from $1,000 a month, with no lock-in contract, and the $199 whole-site AI audit comes off your first month.
