What is Generative Engine Optimisation (GEO)?

THE SHORT ANSWER

Generative Engine Optimisation (GEO) is the practice of making your information clear, useful and attributable inside generative, AI-powered search experiences — such as Google AI Overviews, ChatGPT search and Perplexity.

It is not a separate discipline from SEO. It is a lens on the same job: helping machines and people understand why you are relevant.

The terminology around AI-search optimisation is still developing. There is no universally agreed technical standard for GEO. Treat it as a useful shorthand, not a fixed rulebook.

WHAT DOES GEO ACTUALLY MEAN?

GEO describes optimising for the generative layer of search — the part where an AI model reads, synthesises and summarises information from multiple sources rather than simply returning a ranked list of links.

That generative layer now sits on top of the same underlying web that traditional SEO has always targeted. The pages, the entities, the authority signals and the crawlability still matter. What changes is how the information is presented to the searcher — and how a business gets attributed when its information is used.

So GEO is less about a new set of ranking factors and more about a new set of questions:

Is my information clear enough to be extracted?
Is my entity obvious enough to be understood?
Is my authority strong enough to be selected?
Is my attribution clean enough to be credited?

HOW IS GEO DIFFERENT FROM SEO?

In practice, the overlap is substantial. Traditional SEO and GEO share the same foundations: crawlability, indexability, content quality, authority, links and technical health.

Where GEO places greater emphasis is on a few specific things:

Extractability — can a model lift a clean, accurate passage from your page?
Entity clarity — does the page make unambiguous statements about who and what it refers to?
Attribution — is your brand clearly the source, so it can be credited rather than paraphrased away?
Topical authority — does your site demonstrate depth across a subject, not just a single page?

It is not "SEO is dead." It is "the interface is changing, and the same foundations now need to be machine-readable as well as human-readable."

DOES GEO REPLACE SEO?

No.

Generative search experiences are built on top of retrieval — and retrieval depends on the same crawlable, indexable, authoritative web that SEO has always targeted. If your site is not crawlable, not indexed, or not authoritative, it will not be available to be retrieved in the first place.

GEO is best understood as an additional emphasis on clarity and extractability, layered onto a working SEO foundation — not a replacement for it.

WHAT DOES A GEO-AWARE APPROACH LOOK LIKE?

In practice, the work looks familiar to anyone who has done SEO well:

Get the technical foundations right — crawlability, indexability, speed, clean structure.
Make entities clear — consistent identity, clean structured data, obvious relationships.
Write directly answerable content — lead with the answer, then explain.
Demonstrate genuine expertise — original experience, real examples, first-hand data.
Strengthen authority — real external references, consistent public profiles, topical depth.
Structure information clearly — headings, short paragraphs, tables and lists where they genuinely help.

None of that is exotic. The difference is doing it with the generative layer in mind — not writing for bots, but making sure the genuinely useful thing you already wrote is easy for a machine to find, understand and credit.

GEO, AI SEO OR JUST SEO — WHAT SHOULD WE CALL IT?

Honestly? The label matters less than the objective.

Whether you call it SEO, GEO or AI SEO, the job is the same: help machines and people understand why you are relevant.

I tend to use "AI SEO" as the umbrella, because it keeps the connection to foundational SEO obvious and avoids the implication that something entirely new has replaced it. But if "GEO" helps your team focus on the generative layer specifically, use it — just do not let the terminology convince you the fundamentals have changed.
