What is Generative Engine Optimisation (GEO)?
Generative engine optimisation, or GEO, is how you get your business into AI-written answers. Here is what GEO means, how it differs from SEO and AEO, and whether you need it.
Every few years the marketing world invents a new acronym, and right now the one causing the most confusion is GEO. If you have seen it thrown around and quietly wondered whether it is a real thing or just consultants inventing work, here is the honest answer. GEO is real, it matters, and it is simpler than the jargon makes it sound.
Generative engine optimisation, or GEO, is the practice of shaping your content so that generative AI tools cite your business when they write answers. When someone asks ChatGPT, Google’s AI Overviews, Perplexity or Gemini a question, those tools compose a reply from a handful of sources they trust. GEO is how you become one of those sources.
GEO, AEO, SEO: cutting through the acronym soup
The three terms overlap, and pretending they are wildly different helps no one. Here is the clean version.
- SEO (search engine optimisation) gets a page ranked in a list of links, so a person clicks through to your site.
- AEO (answer engine optimisation) gets you to be the answer to a question, whether that shows up as a featured snippet, a voice result, or an AI reply. We covered this in SEO vs AEO.
- GEO (generative engine optimisation) is the newest and most specific of the three: being cited inside answers written by generative AI.
In day-to-day practice, AEO and GEO are close enough that most businesses should treat them as one job. The work that gets you quoted by ChatGPT is the same work that wins a featured snippet. So do not get lost in the labels. The point is the shift underneath all three: from ranking a link, to being the answer.
How generative engines choose their sources
To do GEO well, it helps to understand what the machine is actually doing. A generative engine does not think. It predicts a good answer by drawing on the sources it has learned to trust and the pages it can pull in live. When it builds a reply, it is quietly asking three questions about every possible source: can I read this, do I trust it, and does it clearly answer what was asked.
Everything in GEO comes back to those three. If your content is a black box to a machine, it cannot be quoted. If the wider web gives the machine no reason to trust you, you will not be chosen. And if your page buries the answer under three hundred words of preamble, a clearer competitor gets lifted instead.
Does your business actually need GEO?
Here is the test. Do your customers ask questions online before they buy from you? If they do, then a growing share of those questions are now being answered by an AI, before anyone reaches a website. If your business is not the one being cited in that answer, a competitor is, or worse, a generic non-answer is, and you are simply absent from the moment that shapes the decision.
You do not need GEO because it is fashionable. You need it because the place your customers form their first impression is moving, and being invisible there is expensive. This is the same reason being cited by AI search matters: the impression still happens, even when the click does not.
What GEO looks like in practice
The reassuring part is that GEO is not a dark art. It is good, clear, credible work made legible to a machine.
- Answer the question first. State the plain answer near the top, then elaborate. Generative engines lift self-contained answers, not paragraphs that make them dig.
- Structure for machines. Clean headings, sensible formatting and structured data tell the engine what your content means. This is where solid technical SEO does the heavy lifting.
- Build genuine authority. Consistent business information, real reviews and credible mentions across the web all tell the machine you are a source worth quoting.
- Publish real expertise. Generative engines are trained on the average of everything. A genuine point of view, backed by real experience and specifics, is exactly what they cannot invent and are most likely to cite.
None of that is a trick you bolt on. It is what happens when you do genuinely good work and make it easy to understand.
Where to start
Do not treat GEO as a separate project competing with your SEO. Treat it as the same foundation aimed at a new target. Get the technical basics right so a machine can read you, rewrite your most important content to answer clearly, and build the credibility that makes you worth quoting. Do that, and you are optimised for search engines and generative engines at once.
That is exactly the work we do for the businesses we partner with. If you want to be the name the AI reaches for, not the business it has never heard of, let’s talk.
Frequently asked questions
What is generative engine optimisation (GEO)?
Generative engine optimisation, or GEO, is the practice of shaping your content and online presence so that generative AI tools, like ChatGPT, Google's AI Overviews, Perplexity and Gemini, include and cite your business when they write answers. Where traditional SEO aims to rank a page in a list of links, GEO aims to get your business woven into the AI-generated answer itself.
Is GEO the same as AEO?
They are closely related and often used interchangeably. Answer engine optimisation (AEO) is the broader idea of being the answer to a query, including featured snippets and voice results. Generative engine optimisation (GEO) is the newer, more specific term for being cited inside answers written by generative AI. In practice the work overlaps heavily, so most businesses can treat them as one discipline.
How is GEO different from SEO?
SEO optimises to rank a web page so a person clicks it. GEO optimises to be a trusted source a generative AI quotes when it composes an answer, often before any click happens. GEO depends on SEO fundamentals, crawlable content, clear structure and authority, but the goal shifts from earning the click to being named in the answer.
How do I optimise for generative engines?
Answer real questions clearly and early, structure your content so machines can read it easily, add structured data, and build genuine authority through consistent business information, credible mentions and reviews. Generative engines quote sources they can understand and trust, so GEO rewards clear, credible expertise over keyword tricks.
