GEO, AEO and AI search visibility for expert-led firms. How AI decides who to cite, why your authority is invisible to it, and how to fix it.
Generative engine optimisation (GEO) is structuring what you publish so AI systems - ChatGPT, Perplexity, Google's AI Overviews, Gemini, Claude - cite you when they answer a question. SEO earns a position in a list of links. GEO earns a citation inside the answer itself.
You may also hear it called answer engine optimisation (AEO) or AI search visibility OR just "AI SEO". These are all the same concept - with the same objective - just under different labels.
SEO competes for position. GEO competes for trust.
Not adverts or Paid Placements - your site has to earn its way there.
Why it matters
Around half of Google searches now show an AI summary, heading past 75% by 2028, and most people who use AI search say it's now their main way of deciding who to buy from (McKinsey, August 2025).
An AI recommendation is a stronger lead than a name pulled from a generic search list. The buyer has asked specific questions around their own particular criteria- so the recommendation is trusted and buyers arrive warm, not cold.
Why expert-led firms are the most exposed
For expert-led firms this matters more than for most. AI search assesses whether the public web can substantiate you.
Your public profile is now not only your shop window, it's your evidence layer.
Many professionals are credible in ways AI can't surface: client relationships, closed networks, warm introductions and internal reputation. Those things still matter, but they don't automatically transfer into AI search.
AI systems need enough evidence to understand what you do and why you are credible. A strong digital footprint becomes a stronger qualification metric. A thin website, poor search presence, limited proof and weak third-party evidence make a firm harder to understand and easier to discount.
A firm may have strong clients, strong results and a solid offline reputation. But if those signals are trapped in private conversations, they are harder for new buyers to verify and harder for AI systems to qualify, which becomes a real commercial risk.
Public content is how private expertise becomes visible, readable and verifiable. LinkedIn posts that show judgement, articles that explain thinking, case studies that prove results, press mentions that substantiate claims. They matter more than they ever have.
The firms that win the next few years will be the most credible in private and the easiest to verify in public.
How AI decides who to cite
AI engines do not rank you. They decide whether your expertise is visible and verifiable enough to stand behind. When buyers name a brand in an AI query, nearly half the sources the AI cites back are earned media, editorial mentions, reviews, forums and independent sites, not the brand's own pages (analysis of 23,000+ AI citations, January 2026).
For an expert-led firm that means two things. Specificity wins: "many firms see results" gets skipped, while a named figure from a named source gets quoted. And third-party mentions outweigh your own claims, so press, an independent roundup or a credible review does more for you than anything you say about yourself.
The work, then, is to be specific, sourced and corroborated, rather than to sound impressive.
What to do first
Open ChatGPT or Perplexity. Ask the questions your best prospects might ask, starting with the obvious one: "Who are the best [wealth managers / litigation firms / financial advisers] in [your city]?"
If your firm is not in the answer, that is a structural visibility gap.
Then check what AI can actually see. Your AI-readability score:
Every "no" is a gap between your real authority and the version AI can read. The rest of this page is how you close it.
How to get cited in AI search
Answer the question directly, near the top. AI quotes clean, self-contained answers. Buried points never get read.
Back claims with named statistics and sources. Specific and sourced gets cited; vague gets skipped.
Structure it for machines. Headings that mirror real buyer questions, FAQ blocks, and the right schema behind the scenes.
Build corroboration beyond your own site. Press, directories, expert roundups, a consistent profile. AI trusts what is confirmed in more than one place, and favours earned media over self-claims.
Keep your details consistent. Same name, description and service detail across your site, LinkedIn and listings, so AI builds one coherent picture of you.
Track it. Ask the AI engines, monthly, the questions your buyers ask. Log whether you appear. Citation is measurable.
Common questions
What is generative engine optimisation (GEO)? Structuring your content so AI systems like ChatGPT and Perplexity cite you when they answer a question. SEO ranks you in a list; GEO makes you the source.
Is GEO different from AEO, AI search visibility or AI SEO? No. Same objective, different names. The tactics are identical.
How is GEO different from SEO? SEO competes for a place in a list the user clicks. GEO competes to be cited inside the answer, where there is often no list and no click.
Does it matter for professional services? More than for most. Your buyers ask AI for recommendations. If your credibility is not visible and verifiable online, AI leaves you out.
How do you get cited? Answer directly, back claims with named sources, structure it for machines, build third-party corroboration, keep your details consistent, and track it monthly.
How long does it take? It compounds. Citations on low-competition questions within weeks, broader authority over months.
