What is AEO, and why your business probably needs it now.
Answer Engine Optimisation, in plain English — what changed, what it actually costs you to ignore it, and how to start without buying another agency retainer.
For twenty years, search was a list of blue links. You typed a question, Google handed you ten websites, and the entire SEO industry orbited around being one of those ten. That arrangement is over. By the end of 2025, more than half of Google searches in the UK end without a click — the answer is already on the results page, generated by Google’s AI Overviews. Perplexity and ChatGPT serve millions of queries a day that never touch a search engine at all. For a small business, the question has quietly stopped being “how do we rank?” and started being “how do we get cited?”
That second question is what AEO — Answer Engine Optimisation — tries to answer. It is genuinely new work, with overlaps with the old work, and most of the people selling it don’t know what they’re doing yet. This is a short, opinionated guide for small-business owners who’d like to skip the buzzwords and understand what to actually do.
What changed
Three things, in roughly this order. Google launched AI Overviews across most of the English-speaking web in 2024 and expanded them aggressively through 2025. ChatGPT added live web search in late 2024, then real-time browsing in 2025. Perplexity grew into a genuine destination — not a curiosity — over the same period. The combined effect is that, for any question a customer might ask before they buy, there’s now a meaningful chance the answer arrives before they get to your site.
This is a different problem from ranking. Ranking is competitive: ten slots, you fight for one. Citation is more like being a footnote — an answer engine reads twenty sources, synthesises one paragraph, and cites three or four of them at the bottom. Your job is to make sure you’re in the three or four.
What AEO actually is
It’s not a checkbox
Several agencies are now selling “AEO audits” that consist of running your site through a tool, generating a 40-page PDF, and adding FAQPage schema to your contact page. That is not AEO. That is SEO theatre with a new sticker.
It’s not separate from SEO
AEO and SEO share most of their fundamentals. If your site loads slowly, has a confusing information architecture, or buries its answers under marketing copy, you won’t rank and you won’t be cited. The work that fixes one mostly fixes the other. Where they diverge is in emphasis. Specifically:
- AEO weighs question-and-answer phrasing heavily — pages that pose a real question and answer it directly in the first paragraph.
- AEO leans on entity clarity — the answer engine needs to be confident that “Trax Hydraulics” is the same entity in twelve different sentences across your site.
- AEO rewards specificity over generic authority — a 600-word page that answers one narrow question well will out-cite a 3,000-word page that grazes ten.
- AEO is much less forgiving of hedging and marketing voice — answer engines need declarative sentences, not “we believe in” copy.
“If your customer’s first search result is an answer, you are no longer competing for clicks. You are competing to be the source.”
How to know if your business is exposed
Four quick tests, in roughly increasing order of seriousness. Don’t hire anyone before you’ve done these yourself; they take about an hour.
- Open Google in an incognito window and search for the question your best customer asked you last week. If an AI Overview appears and doesn’t cite you, that’s exposure.
- Do the same on Perplexity. Then ChatGPT, with browsing enabled. If you’re absent from all three, your competitors aren’t.
- Search your own brand name on each. If the answer is wrong, outdated, or confidently fabricated, that’s a brand problem, not just a search problem.
- Check your analytics for direct traffic and branded search. If both are growing while organic clicks are flat, you’re probably being cited but not clicked — which is fine if you’re tracking it, and dangerous if you’re not.
Where to start
Audit your top 20 pages
Not all of them. The twenty that get the most search traffic today, plus any commercial-intent pages that don’t. For each, ask: what question does this page answer, and is the answer in the first paragraph? If the answer is buried under three paragraphs of brand voice, rewrite the opening.
Mark up answers, not pages
Most sites stop at Article or Organization schema. AEO cares more about the structured-data types that describe answers directly. The two that matter most:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What is AEO?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Answer Engine Optimisation: the
practice of making your site readable,
citable, and trusted by AI answer
engines like Google AI Overviews,
Perplexity, and ChatGPT."
}
}]
}
</script>Don’t over-do it. Schema is a hint, not a magic spell — pages that already answer well don’t need it, and pages that don’t can’t be saved by it.
Write the way an engineer would
Plainly. Without hedging. Without marketing voice. If you’re tempted to say “we pride ourselves on,” delete the sentence and write what you actually do instead. Answer engines do not parse pride.
If you read this far and you’re thinking “this is the SEO playbook with extra steps,” you’re mostly right — and you’re ahead of about 80% of agencies still selling AEO as a separate product. The work that makes you findable now is the same work that makes you findable in five years: be specific, answer questions, write plainly, and don’t bury the lede. For small businesses with a real specialism, this is straightforwardly good news.
If you’d like a second opinion on where you stand, my SEO consulting engagements include an AEO baseline as standard, and there’s a separate AEO consulting service for businesses that want it run independently. Or just send me an email — I read all of them, and I’ll usually tell you within a paragraph whether you need help or not.
