Answer Engine Optimisation for Beginners | Plain English Guide to AEO

Last month I was having a pint in Hitchin with a mate who runs a gardening business. Decent operation, five-man crew, covers most of North Hertfordshire. He asked me what I'd been up to and I said "answer engine optimisation" and he looked at me like I'd made it up on the spot.

"That's not a real thing."

It is.

And by the end of this post you'll understand what it is, why it matters if you run a local business, and what you can actually do about it without needing a computer science degree.

Forget everything you know about getting found online

OK maybe not everything. But the mental model most people have goes something like this: you build a website, you stuff some keywords in, you get it ranking on Google, customers find you and call. That's SEO. Search Engine Optimisation. It's been the game for twenty years and it still matters.

But there's a new game running alongside it now.

People are asking AI systems questions instead of typing keywords into Google. They open ChatGPT and say "I need someone to fix the damp in my Victorian terrace in Royston, who's good?" They use Perplexity and ask "how much does a new bathroom cost in North Hertfordshire?" They Google something and before they even see the normal results, there's an AI-generated answer sitting at the top.

These AI systems don't show a list of ten websites. They give one answer. Maybe two businesses mentioned by name. With reasons.

Answer engine optimisation is about making sure your business is that answer.

A tale of two roofers

I'll give you a real example because it makes the point better than theory.

Two roofing companies. Both work across Stevenage and surrounding areas. Company A has a lovely website, ranks well on Google, SEO agency on retainer, the works. Company B has a basic WordPress site that looks like it was built in 2019 (because it was).

I typed "who does flat roof repairs in Stevenage" into Perplexity.

Company B came up. With a citation. The AI quoted their flat roofing page, mentioned their 5-year guarantee, noted their average project turnaround of 3-4 days, and linked to their site as the source.

Company A? Nowhere.

The difference wasn't design or domain authority or backlinks. The difference was that Company B's website clearly stated what they do, where they do it, how much it roughly costs, and how long it takes. Factual. Specific. Written like a human explaining their trade to another human.

Company A's website said "we provide professional roofing solutions across Hertfordshire with a commitment to excellence."

You can probably guess which one gives an AI something useful to cite.

Right, so what does AEO actually involve?

This is the bit people want to know so I'll keep it plain.

Answer engine optimisation is about structuring your online presence so that AI systems can find your information, understand it, trust it, and cite it when someone asks a relevant question.

It breaks down into a few things:

Your content needs to answer real questions. Not "why choose us" fluff. Real questions that real people ask. How much does it cost. How long does it take. What's the process. What areas do you cover. What happens if something goes wrong. The stuff you answer on the phone twenty times a week.

Your information needs to be consistent everywhere. Your website, your Google Business Profile, your directory listings, your social media, your review profiles. If your phone number is different on Yell versus your website, or your business name has three variations floating around the internet, AI systems get confused and skip you.

You need to be specific, not vague. "Serving all of Hertfordshire" is weak. "Based in Letchworth, working across Hitchin, Baldock, Stevenage, and Royston" is strong. "General building work" is weak. "Loft conversions on 1960s and 70s semis, typically 6-8 weeks, planning permission handled" is strong.

You need third-party validation. Reviews, mentions in local directories, citations on community sites. The AI doesn't just take your word for it. It checks whether other sources back you up.

How is this different from normal SEO though?

Fair question. I get it a lot.

SEO is about ranking in a list of search results. You're trying to be number one (or at least on page one) when someone searches a keyword. The better your technical setup, your backlinks, your content, the higher you rank.

AEO is about being cited as an answer. Not appearing in a list. Being the actual response.

They overlap, sure. Good content helps both. A well-structured website helps both. But the emphasis is different.

With SEO, you might rank number one for "accountant Baldock" and still get no AI citations because your page says "trusted accountancy firm with 20 years' experience" and nothing else useful.

With AEO, you might not even rank on page one, but if your content clearly answers "how much does a self-assessment tax return cost for a sole trader in Hertfordshire" with real numbers and real detail, the AI will find you and cite you when someone asks that question.

I've seen this play out with real businesses. A small accountancy firm in Royston (three staff, basic website) gets cited by ChatGPT regularly because she wrote genuinely helpful content about tax deadlines and costs. A much bigger firm down the road with a £15,000 website doesn't get a mention. Not once, in all the queries I've tested.

Where to actually start

If you've read this far and you're thinking "right, what do I do on Monday morning," here's what I'd suggest.

Step one. Go to ChatGPT or Perplexity and search for your own business. Ask the kind of question a customer would ask. "Who does X in Y town?" "How much does X cost near Y?" See what comes up. See who gets mentioned. That's your baseline.

Step two. Write down ten questions your customers actually ask you. On the phone, in person, in emails. The real ones, including the ones about money that you'd normally prefer to discuss face to face.

Then answer them. Properly. On your website. Three hundred words each, minimum. Write like you're talking to your neighbour who genuinely needs to know. Mention local areas where relevant. Include actual numbers where you can.

That's your foundation.

Step three. Sort your Google Business Profile. I know, everyone says this. But most people's profiles are half-finished. Every service listed individually. Hours accurate. Photos from this year. The Q&A section filled out. A post every month or so. I wrote a whole piece on Google Business Profile and AI search if you want the detail on why this matters so much now.

Step four is the technical stuff. Schema markup, structured data, entity optimisation. This is where it gets into territory where having someone who does this full time makes sense. It's not impossibly complex, but it's the kind of thing where mistakes are easy and invisible, and you won't know you've got it wrong until you wonder why you're still not showing up.

The beginner mistakes I see constantly

Creating thin location pages. "Plumber Hitchin." "Plumber Letchworth." "Plumber Baldock." Same text, different town swapped in. AI systems see through this instantly. It might actually hurt you.

Writing content for search engines instead of humans. If your service page reads like it was designed to hit a keyword density target rather than explain something useful, the AI won't cite it. It might not even read it properly.

Ignoring your Google Business Profile. "But I've already got a website." Great. They serve different purposes. AI systems pull from both. If your Business Profile is a ghost town from 2022, that's a signal.

Thinking this only matters for ChatGPT. Google's AI Overviews, Perplexity, Bing's AI, Claude. They're all doing this. Every major search platform is moving toward giving direct answers. This isn't a single-platform trend.

The bit about timing

I'll be straight with you. Most local businesses haven't started thinking about answer engine optimisation yet. They're still in pure SEO mode. Still obsessing over keyword rankings and backlink profiles and the stuff that mattered in 2018.

Which means there's a window right now. Maybe a year. Maybe less. Before everyone catches on and it becomes much harder to stand out.

The businesses I've been working with who started six or seven months ago are already pulling ahead. They're getting cited in AI results. They're getting enquiries from people who say things like "the AI recommended you" or "Perplexity said you were good for this." Those enquiries tend to convert better, too, because the customer arrives already understanding what you do and roughly what it costs.
