GEO vs AEO: Two Different Problems, One Business Impact

The confusion is completely understandable (we don't judge)

AEO. GEO. SEO. At a certain point it does start to sound like someone dropped a Scrabble bag and ran with it. Bear with us — the distinctions genuinely matter, and once you see them clearly, the whole picture snaps into focus.

AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) both describe optimisation for AI-driven responses. Both involve structured content and schema markup. Both aim to get your business cited rather than just ranked. And both are disciplines that most London businesses haven't touched yet — which is, frankly, an opportunity.

But the platforms they target are different. The customer behaviours they address are different. The content structures that win results are different. Treating them as the same thing produces a strategy that half-serves both — like wearing one shoe from two different pairs. Technically covered. Not actually right, and uncomfortable to walk in.

AEO: winning the spoken answer

AEO is about voice search — Siri, Alexa, and Google Assistant. When a customer asks their phone or smart speaker a question about a local business, AEO determines what they hear back.

The interaction is immediate and local. "Locksmith near me tonight." "Dentist open now in Camden." "What's a good Thai on Upper Street." These are queries asked in the moment — driving, cooking, standing in a hallway — queries that expect a spoken, single answer right now. No scrolling. No browsing. One name, read aloud, done.

The scale of this is worth understanding. According to Statista, there were over 8 billion digital voice assistants in use globally by 2023 — more than one per person on the planet. Closer to home, Ofcom's research consistently shows UK smartphone penetration above 90%, with voice assistant usage particularly high among commuters — which, in London, is basically everyone.

The content that wins voice answers is structured, concise, and directly responsive to the question format. Google's Speakable schema tells voice platforms which parts of your page are suitable to read aloud. Featured snippet capture is the most reliable pathway to becoming the Google Assistant answer for a given query. AEO is fundamentally about local intent and immediate conversion — the customer isn't researching, they're deciding.

(Why is AEO like a good joke? Because timing is everything. The business that's structured its content for voice search gets the customer at the exact moment they're ready to act. The business that hasn't gets nothing — and doesn't even know what it missed. Unlike a bad joke, there's no awkward silence. Just silence.)

GEO: winning the AI citation

GEO is about AI language models — ChatGPT, Perplexity, Google Gemini, and Microsoft Copilot. When a customer opens one of these tools and asks a question that leads to a local business recommendation, GEO determines whether your business gets named.

This interaction is different from voice search in ways that matter commercially. It tends to happen during a deliberate research session. Someone sitting at a desk, or on their phone on a Sunday evening, trying to form a considered view on something significant — a solicitor to handle a dispute, an accountant to sort out their finances, a contractor to renovate their kitchen. They're building a shortlist, not acting on impulse. The intent is real, and the commitment tends to follow.

BrightLocal's research has tracked the shift in how people research local businesses for years, and the direction is consistent: AI tools are becoming a meaningful part of the funnel for higher-consideration purchases. Customers looking for professionals — solicitors, accountants, builders, specialists of any kind — are increasingly likely to ask ChatGPT before they ask Google. If you're not in the AI response, you're not in the shortlist.

The important thing to understand about GEO is how AI tools actually construct their responses. They don't pull directly from your website the way a voice assistant does. They synthesise from training data, web indexing, and entity knowledge — from what they understand your business to be, and how other credible sources talk about it. GEO is about becoming a well-understood, well-cited entity in the places AI models draw from. Less "page rank", more "professional reputation."

If AEO is about raising your hand in class to answer the question, GEO is about being the person all the other students whisper "ask them" about when someone needs help. One is a content structure problem. The other is a reputation-building problem. Both are absolutely solvable — but they're not the same problem, and treating them as one means you solve neither properly.

The key differences, side by side

Neither column is better. They're just different customers, at different moments, with different needs. Ignoring either one is leaving money on the table — specifically, other people's money, going to whoever did bother to show up.

Where they overlap — and why that matters

Despite the differences, AEO and GEO share significant technical foundations. Strong local entity signals benefit both. Clean structured data and complete JSON-LD schema support both. High-quality, directly-answerable content performs in both contexts. A fast, well-structured website is a prerequisite for both.

That overlap matters practically. A well-executed AEO strategy isn't wasted effort from a GEO perspective — the technical groundwork carries over directly. We run them in parallel for exactly this reason. A business building both together compounds faster than one treating them as two separate projects with a queue between them.

The place where they diverge most sharply is in the off-page work. AEO relies heavily on featured snippet capture and local content — primarily on-site optimisation. GEO requires a broader citation signal network: mentions, references, and entity acknowledgements across directories, industry publications, community platforms, and authoritative sources that live entirely outside your own website. This is the workstream that takes the most consistent effort to build — and the hardest for competitors to replicate quickly once you've built a lead.

According to Moz's local SEO research, citation consistency and entity authority are among the most important signals for local ranking — and those same signals feed directly into how AI models understand and represent local businesses. Fix them once, and they work across all three channels: traditional search, voice, and AI.

A practical example: the Hackney solicitor

Abstract distinctions are fine. But let's make this concrete. Consider a solicitor in Hackney. Here's how AEO and GEO serve them differently — and why both matter.

AEO scenario: A resident in Hackney has a landlord dispute. It's a Thursday evening, they're frustrated, and they ask Alexa: "Find me a solicitor in Hackney." This is an immediate-intent query. There's no deliberation happening. Alexa reads out one name. If that name is our Hackney solicitor, they get a call on Friday morning. If it isn't, they get nothing — and no notification that they missed it.

GEO scenario: A small business owner is relocating their office to Hackney. On a Sunday evening they open ChatGPT and type: "Can you recommend a commercial property solicitor in East London with experience in lease negotiations?" This is a research query. They're forming a shortlist. GEO ensures the solicitor is named in the response — which leads to an instruction the following week, probably worth several thousand pounds.

Both interactions have genuine commercial value. Neither replaces the other. And both are being lost by most Hackney solicitors today, because neither AEO nor GEO has been implemented at all. They're relying on a Google ranking from three years ago and hoping for the best. (This is technically a strategy. It's just not a great one.)

The legal sector is a good example because it illustrates the stakes per interaction clearly. One new client from a GEO citation can represent thousands of pounds in fees. One voice search answer can drive a same-day appointment. The ROI maths on getting this right are not subtle.

The London angle

London is both the hardest and the most rewarding market to do this in — which sounds like a paradox but isn't. The competition for traditional SEO in London is fierce. Established agencies, large budgets, years of accumulated domain authority. That race is hard to win from scratch.

AEO and GEO are different. BrightLocal's voice search research consistently shows that most local businesses — including London ones — have done virtually nothing to optimise for voice. The competitive field is wide open. London's density makes voice search particularly valuable (five competitors within walking distance, and the customer can only hear one name), and London's tech-forward demographic means AI tool adoption is higher here than in most other UK markets.

The businesses that establish AEO and GEO authority in London now will hold positions that are genuinely hard to displace later — not because the work can't be replicated, but because the compound effect of arriving first is significant. The window is still open. It won't stay that way.

London rewards the early movers here. Not necessarily the most funded, not the best-branded — the ones who showed up in these channels before it became obvious that they mattered. That window still exists. It won't exist forever.

The bottom line

If you're only doing traditional SEO, you're visible in one channel while your customers search across three. AEO adds voice. GEO adds AI tools. Neither is a fringe technology or a future trend — both are happening now, with real customers finding real businesses, or not finding them and finding someone else instead.

The technical foundations overlap enough that building all three together is more efficient than addressing them one at a time. Content that wins a featured snippet also improves your GEO entity signals. The FAQ structure that powers AEO is the same structure AI models prefer to extract from when building their responses. One body of work, three channels benefiting from it.

The businesses that establish all three now will be genuinely difficult to displace by the time their competitors notice what's happened. That's a comfortable position to be in. The alternative — realising this in eighteen months and trying to close the gap — isn't.
