Two mechanisms. Most GEO advice ignores both.

Almost every argument about generative engine optimisation comes from conflating two completely different things: what a model learned when it was built, and what it fetches when it answers.

Short answer

Generative engine optimisation improves how likely an AI system is to use and cite your content. It works through two distinct mechanisms: training, which is fixed until the next model and cannot be influenced quickly, and retrieval, which happens live when an assistant searches the web and is genuinely influenceable today.

01 The mechanics

Training and retrieval behave differently.

Training is what a model absorbed when it was built. If your business was not well described on the web at that point, nothing you publish today changes it — the corpus is fixed until the next model ships. This is why new businesses are invisible to assistants and why patience is not optional.

Retrieval is different. When an assistant searches the web to answer a question, it fetches pages now and quotes them now. That is where work you do this month can land, and it is why crawler access and current, clearly written pages matter more than most GEO advice suggests.

The term itself comes from a 2023 academic paper by researchers at Princeton, Georgia Tech, the Allen Institute for AI and IIT Delhi, which measured which changes to a source page altered its visibility inside generated answers. It found additions such as quotations, statistics and cited sources helped, while conventional keyword optimisation did comparatively little. That is evidence about specific systems at a specific time — considerably more than most GEO advice rests on, and not a permanent rulebook.

02 Implications

What follows from the mechanism.

Each of these is a consequence of how retrieval works, not a guess about a ranking factor.

Practical implications

  • Be retrievable. If retrieval crawlers cannot read your page, you cannot be quoted in a live answer.
  • Be self-contained. A retrieved page is read in isolation, without your navigation. Pages that only make sense in sequence are poor sources.
  • State facts explicitly. Models quote specifics. Positioning language contains nothing to lift.
  • Attribute your claims. Sourced statements are safer to repeat, which appears to make them more likely to be used.
  • Be consistent everywhere. Contradictions between your site and your profiles give a model reason not to name you at all.
  • Keep it current. A visible review date is cheap and retrieval appears to favour pages that look maintained.

03 Scepticism

Five questions that dispose of most GEO claims.

Apply these to anything sold to you as generative engine optimisation, including by me.

What is the mechanism?
If the answer is not training or retrieval, ask again. Everything real routes through one of the two.
Where is the source?
A paper, a platform announcement or a documented crawler. "Industry data" without a citation is not a source.
Can it be measured?
If the only evidence is a proprietary score, it cannot be independently checked.
Would it help anyway?
Consistent descriptions and clear content help conventional search too. Tactics that only pay off if the AI theory is right are the risky ones.
What happens at the next model update?
Anything depending on a current quirk stops working. Anything based on genuine credibility does not.

Three faults, in the same order, every time.

Almost every underperforming account I open has the same three problems. None of them are exotic, all of them are visible within an hour, and fixing them usually matters more than any bid strategy.
