Generative Engine Optimisation: what it is and how to do it

What generative engine optimisation means

Generative engine optimisation is the practice of structuring a site so that AI answer engines cite it as a source. Those engines include Google's AI Overview, ChatGPT, Perplexity and Claude. The unit of success is not a position in a list — it is whether your domain appears in the answer the user actually reads.

The distinction matters because the two outcomes have come apart. A page can hold position three and be the only source an AI Overview quotes. A different page can hold position one and be skipped entirely while the answer cites three sites from further down. Ranking and citation are related but no longer interchangeable, and optimising for one does not automatically deliver the other.

Why the change happened

A traditional search result gives the user ten options and asks them to choose. A generated answer gives them one synthesised response assembled from a handful of sources. The engine has to decide which passages are quotable, which claims are attributable, and which sites are safe to name. That decision is made at the level of the passage, not the page.

The practical consequence is that content written to rank — long, keyword-led, building slowly to a conclusion — is often poorly shaped for citation. Content written to be quoted states its answer immediately, in a form that survives being lifted out of context.

What influences whether you get cited

1. Answer-first structure

Lead with the answer. If the question is "what is a generative engine optimisation tool", the first sentence after that heading should define it in one or two self-contained sentences. A passage that depends on the paragraph above it to make sense is much harder to quote.

2. Machine-readable structure

Structured data does not force a citation, but it removes ambiguity about what the page asserts. FAQPage markup pairs an explicit question with an explicit answer. HowTo markup does the same for a process. Both should mirror content that is visible on the page — markup describing content a visitor cannot see is a policy violation, not a shortcut.

3. Specific, attributable claims

Generated answers favour statements that can be attributed without risk. Concrete figures, named methods, dates and defined terms are easier to quote than general enthusiasm. "Rank tracking from £29 a month with daily checks on Pro" is quotable. "Affordable, powerful rank tracking" is not.

4. Content the crawler can actually see

If your page renders its content through client-side JavaScript, there is a real chance the crawler sees an empty shell. Server-render the content that matters. This is the least glamorous item on the list and the one most likely to be silently costing you every citation.

5. Topical depth around the question

A single page rarely establishes authority on its own. Supporting pages that cover adjacent questions — and link to each other — give the engine more context for treating your domain as a reasonable source on the subject.

How to measure it

GEO is unusually hard to eyeball. Answers vary between users, engines refresh on different cycles, and a citation you had last week can quietly disappear. Checking manually gives you an anecdote, not a trend.

Useful measurement tracks four things over time:

• Whether an AI Overview appears at all for each keyword — some queries trigger one and some do not, and that changes.
• Whether your domain is cited when it does appear, and in which position among the sources.
• Which competitors are cited instead, so you can read the pages the engine preferred.
• Whether assistants name you when asked the questions your customers actually ask.

Verosite Visibility records all four alongside classic Google positions, so you can see a ranking hold steady while citation quietly slips — the failure mode a rank tracker alone will never show you. You can check any domain free without signing up, or read what a full AI visibility report contains.

A practical starting sequence

1. Take the ten questions your customers ask most often, in their words rather than your keyword list.
2. Check which of those already trigger an AI Overview, and whether anyone in your market is cited.
3. For each question with an Overview and no citation for you, find the page on your site that should answer it — or accept that none does.
4. Rewrite that page answer-first: question as a heading, answer in the first two sentences, detail afterwards.
5. Add FAQ or HowTo markup that mirrors the visible content exactly.
6. Re-check after the page is recrawled, and keep checking — citation is a state that changes, not a milestone you reach.

What GEO does not change

The foundations still apply. A page that cannot be crawled cannot be cited. A site with no authority on a subject will not become the source of record because it added markup. Thin content does not become quotable by being restructured. GEO is a shift in what you optimise the content shape for, not permission to skip the fundamentals.
