Quick answer: Answer engine optimisation (AEO) is the practice of structuring content so AI answer engines - Google AI Overviews, ChatGPT, Perplexity, Gemini and Copilot - can extract, trust and cite it in their answers. The win condition has changed: it is no longer just ranking in a list of links, it is being quoted as the answer.
In this guide:
- What AEO is, and why "cited" has replaced "ranked" as the goal.
- The 2026 UK data: AI Overviews on ~30% of searches, and what that does to clicks.
- The playbook that actually wins citations - plus the llms.txt myth, busted.
Written for UK business owners, marketing managers and founders watching AI answers reshape search - from local firms to growing SMEs and mid-market technology companies.
Search is splitting in two. There is still the familiar list of blue links, and then there is the AI answer sitting on top of it - the Google AI Overview, the ChatGPT reply, the Perplexity summary - that increasingly answers the question before anyone clicks anything.
For UK businesses, that creates an uncomfortable question. If an AI writes the answer, where does that leave your carefully optimised page? The honest answer is that ranking still matters, but it's no longer enough. The new goal is to be the source the AI quotes. That's what answer engine optimisation is for.
This guide is a practitioner's walk-through, not a hype piece. We cover what AEO actually is, how it relates to the alphabet soup of GEO, LLM SEO and AI SEO, what the UK data really shows, how AI engines pick their sources, the tactics that earn citations, how to measure any of it - and which popular "AI SEO" advice is a waste of your time. We build to this spec ourselves, and we'll show you where the evidence is strong and where it's thin.
What is answer engine optimisation?
Answer engine optimisation (AEO) is structuring your content so AI answer engines can extract, trust and cite it when they generate an answer. Where classic SEO competes to rank in a list of links, AEO competes to be quoted inside the synthesised answer that an AI shows first. The deliverable is a citation, not a position.
An "answer engine" is any system that responds to a question with a single synthesised answer rather than a page of links: Google's AI Overviews and AI Mode, ChatGPT, Perplexity, Gemini, Microsoft Copilot and Claude. They read across multiple sources, blend the relevant facts and return one answer, usually with a handful of citations attached. AEO is the discipline of making sure those citations point to you.
How AEO differs from traditional SEO
The two are not rivals - AEO sits on top of SEO. But the win condition is different, and that changes what you optimise for.
| Traditional SEO | Answer engine optimisation | |
|---|---|---|
| Win condition | Rank high in a list of links | Be cited inside the AI answer |
| Unit of value | A ranking position | A citation or mention |
| Optimised for | Keywords, links, technical health | Extractable answers, entities, third-party trust |
| Content shape | Comprehensive pages targeting a keyword | Answer-first passages a machine can lift verbatim |
| Success metric | Position, organic clicks | Citation share, AI referral traffic, branded lift |
Here's the part that trips people up: AEO doesn't let you skip SEO. AI engines overwhelmingly cite pages that already rank. seoClarity's analysis of more than 432,000 keywords found that around 97% of AI Overviews cite at least one source from the top 20 organic results. If you're not indexed, crawlable and reasonably well-ranked, there's nothing for the answer engine to quote. AEO is what you add once the SEO foundations are in place, not a shortcut around them.
AEO vs GEO vs LLM SEO vs AI SEO: the terminology decoded
AEO, GEO, LLM SEO and AI SEO are overlapping labels for the same underlying job: getting your content cited inside AI-generated answers. The differences are branding and audience, not method. If a vendor tells you these are fundamentally different services, be sceptical.
The market has produced a confusing pile of acronyms, largely because several communities arrived at the same problem from different directions. Academics coined GEO, agencies pushed AEO, engineers favour LLM SEO, and the mass market settled on "AI SEO". Underneath, FactSentry puts it plainly: these all describe the same job - getting cited inside AI answers. Here is how the terms actually map.
| Term | What it means | Where it came from | Best used when |
|---|---|---|---|
| AEO Answer engine optimisation |
Optimising content to be the answer AI engines extract and cite | Practitioner and UK agency term; now the popular "new SEO" framing | Talking to non-specialists about being cited in AI answers |
| GEO Generative engine optimisation |
Optimising for generative answer engines specifically | A 2024 Princeton-led academic study; favoured by specialists | Technical and strategy circles; research-led discussion |
| LLM SEO Large language model SEO |
Structuring pages so LLMs cite them; a superset of SEO | Engineering-led SEO teams and AI-native tools | Working with technical teams who treat AI as a platform |
| AI SEO AI search optimisation |
SEO adapted for AI surfaces; the broad catch-all | Mass-market label used by large vendors and agencies | The generic umbrella when precision is not needed |
| AI visibility The measurement side |
Monitoring how often AI systems mention, cite or link a brand | Tool marketing (Ahrefs, Profound and others) | Reporting and tracking, rather than the optimisation work itself |
The practical takeaway: Pick whichever term your audience understands and stop worrying about the rest. We use "AEO" with clients and "AI SEO" in the broad sense, because the work behind every one of these labels is the same: answer-first content, structured data, clear entities and earned third-party authority. A guide that obsesses over the acronyms is selling you confusion.
Why AEO matters now: the UK data
AEO matters now because AI answers already intercept a large share of UK search clicks. Ofcom reports that around 30% of UK searches show an AI summary, and when one appears, click-through to the top organic result can fall by roughly half. Being cited is becoming the difference between visibility and invisibility.
AI answers are now the default, not the exception
Google rolled AI Overviews out across more than 200 countries through 2025, and the UK felt it fast. seoClarity measured roughly 536% growth in UK AI Overview prevalence on desktop between September 2024 and September 2025. Ofcom's 2025 research puts it in plain terms: around 30% of UK searches now return an AI summary, and 53% of UK adults say they see these summaries often. Add the dedicated answer engines - ChatGPT, Perplexity and Gemini, now used by millions of UK adults - and a meaningful slice of your audience is getting answers without visiting a website at all.
Google is not just responding to this shift - it's actively encouraging it. At its I/O 2026 keynote, Google unveiled the biggest redesign of its search box in 25 years: an "intelligent" box that expands as you type, deliberately nudging people away from short keywords and towards longer, conversational questions. When the world's dominant search engine rebuilds its own front door around conversational queries, the direction of travel is hard to argue with.
When an AI answer appears, clicks fall
This is the uncomfortable bit. When an AI Overview sits above the organic results, fewer people click through. UK publisher data reported via Press Gazette (from Authoritas) shows click-through dropping by 47.5% on desktop and 37.7% on mobile for affected news queries - figures Google contests, though its own direction of travel is not in doubt. Ahrefs' analysis of 300,000 keywords found a 58% reduction in click-through for the number-one position when an Overview is present. Push Group has documented even steeper falls - up to 70-89% - for some informational and publisher sites where the AI answers the question completely.
But being cited flips the maths
Here is the opportunity hiding inside the threat. The same studies show that pages cited inside an AI Overview often see click-through rise by around a third (Seer Interactive). And AI referral traffic appears to convert unusually well: Similarweb found ChatGPT referrals convert at 11.4% versus 5.3% for organic search - more than double. Someone who clicks a citation has already had part of their question answered and is further down the funnel. The lesson is consistent: losing the click is the cost of not being cited; winning the citation is the new prize.
This is already playing out in the UK. When the holiday-parks operator Parkdean leaned into generative engine optimisation, its appearances in AI Overviews reportedly rose by around 680% through 2025, putting it in front of tens of thousands of monthly UK holiday searches (Rise at Seven). The conversion signal keeps recurring too: alongside Similarweb's figures, Seer Interactive recorded ChatGPT visitors converting at roughly 16% against 1.8% for Google organic in one sample, and a 2026 IT-sector benchmark found AI referrals converting four to five times better than organic (Opollo). The exact numbers vary, and most are agency-reported rather than independently audited, but they all point the same way: AI referral traffic is still scarce, but it is unusually valuable when it arrives.
Not sure how exposed you are? The first step is knowing how many of your priority queries now trigger an AI answer, and whether you are cited in them. That is exactly what an SEO audit should now cover.

How AI answer engines choose sources
AI answer engines pick sources in three broad steps: they start from the pages already ranking for a query, narrow to a handful that best answer it, and favour content that is extractable, well-structured and backed by recognisable authority. Ranking gets you considered; clarity and trust get you cited.
The exact selection logic differs by engine and none of them publish it in full, but the patterns are now well documented. Five factors do most of the work.
1. Your organic ranking is the entry ticket
AI Overviews do not invent sources from nowhere - they draw on pages already ranking, then synthesise. seoClarity found that around 97% of AI Overviews cite at least one source from the top 20 organic results, though even the number-one page is cited in only about 43% of them. A separate analysis put roughly 40% of all citations as coming from the top 10. Ranking is necessary but not sufficient: it gets you into the candidate pool, after which extractability and trust decide.
2. Extractability and structure
Engines favour content they can lift cleanly. Perplexity, for example, weights "information density" - a high ratio of concrete facts per paragraph - and rewards clean heading hierarchy, with structured pages reported to perform markedly better for citation than unstructured prose. Content buried in JavaScript is a particular risk: most AI crawlers, including OpenAI's GPTBot and PerplexityBot, do not execute JavaScript at all - Google's is the main exception - so a page that builds its content client-side can look empty to them and never get cited.
3. Entities and the knowledge graph
LLMs ground their answers in entities - well-defined people, brands, products and concepts - not just keywords. Being a recognised entity, with consistent details across your site, Google Business Profile, directories and ideally Wikipedia, makes a brand far easier for an AI to confidently name. This is why entity SEO has quietly become an AI tactic, not just a local one.
4. Third-party authority and mentions
AI engines treat what others say about you as a strong trust signal - often stronger than your own site. Profound's analysis of millions of citations found Reddit was the most-cited domain on Google AI Overviews and Perplexity, with Wikipedia top on ChatGPT, and the models treating niche subreddits as subject-matter experts. Mentions on review platforms and industry publications matter too: one analysis found brands cited across sources like G2, Reddit and a couple of industry publications achieved far higher AI citation coverage than those relying on owned content alone. Earned distribution compounds the effect - a March 2026 study by Stacker found that syndicating content through third-party publishers produced a median 239% lift in AI citations versus owned content alone.
5. Freshness
Answer engines, Perplexity especially, lean towards recent content. A dated page on a fast-moving topic is less likely to be pulled into an answer than an equivalent page updated this quarter. For topics like this one, keeping content current is itself a citation signal.
The uncomfortable implication: you can't fully control how an AI represents you, because a large part of the signal lives on third-party sites - Reddit threads, reviews, industry coverage. AEO is therefore as much about earning a reputation off your own site as polishing the pages on it.
The AEO playbook: what actually wins citations
The AEO tactics with real evidence behind them are: answer-first writing, high information density, structured data, entity building, earned third-party authority and basic AI-bot crawlability. The Princeton GEO study (KDD 2024) found that citing credible sources, adding statistics and including quotations were among the most effective levers, with reported improvements in AI visibility of up to around 40%.
1. Write answer-first
Open every section with the answer. Lead with a clear, declarative 40-60 word response to the heading's implied question - the sentence you would want quoted back to a customer - then add depth underneath. LLMs reward pages that answer immediately and penalise marketing throat-clearing. This single habit, applied across a site, does more for AEO than any technical tweak.
2. Raise information density
Pack concrete facts, numbers, dates and named sources into your paragraphs. Vague, hedging sentences do not get cited; specific, attributable ones do. Aim for the pattern "specific claim plus number plus source" - exactly the pattern AI engines look for when deciding what to quote. Longer is not automatically better: engines extract, they do not read, so density beats word count.
3. Add structured data for AI
Schema markup won't magically rank you, but it makes content unambiguous to machines. Prioritise Article, FAQPage and HowTo schema, plus Organization and LocalBusiness to reinforce your entity. Be realistic about what it does, though: the evidence that schema directly lifts AI citations is mixed - Ahrefs found little effect, while other studies report gains - so treat it as table stakes for machine-readability, not a magic lever. Clean heading hierarchy, comparison tables and FAQ sections all give engines tidy, liftable chunks. This page uses exactly that markup.
4. Build your entity
Make your brand easy to recognise and verify. Keep your name, address and details consistent across your site, Google Business Profile and the directories that matter in your sector, and earn a presence on the high-trust sources AI engines lean on. The more consistently the web describes you, the more confidently an AI will name you.
5. Earn third-party authority
Because AI engines weight what others say about you, you have to participate in the conversations they read. That means genuine reviews on the platforms relevant to your sector, useful contributions in industry forums and communities, and earned coverage in the publications your buyers trust. Promotional spam gets discounted; helpful, substantive contributions get cited.
6. Let the AI bots in
None of the above matters if the crawlers can't reach you. Check that your robots.txt does not block the AI crawlers you want - and mind the distinction that trips people up: OpenAI's GPTBot governs training, while its separate OAI-SearchBot is what surfaces you inside ChatGPT's search, so block by intent rather than by reflex. The same care applies to PerplexityBot, ClaudeBot and Google-Extended. An AI-bot crawlability check is the cheapest, highest-leverage first step in any AEO project.
The llms.txt myth, busted
You may be told that an llms.txt file - a curated map of your content for language models - is essential for AI visibility. The evidence says otherwise. No major AI provider has committed to reading it. Ahrefs found that of around 38,000 valid llms.txt files, 97% received zero requests in May 2026, and Google's John Mueller flatly stated it is "not done for search".
It's harmless to add and may help AI coding tools parse developer docs, but selling it as a route to AI visibility is, on current evidence, selling hype. Spend the time on answer-first content and crawlability instead. We'd rather tell you that than charge you for a file no bot reads.
That is a lot of moving parts. Answer-first rewriting, schema, entity work, crawlability and third-party authority all compound - but they take time and a system to do well across a whole site.

How to measure AEO
Measure AEO on three layers: AI Overview presence and citation share (are you in the answer?), AI referral traffic in GA4 (is it sending visitors?), and share of model (how often AI engines name you versus competitors). Rankings alone no longer tell the full story, because you can rank and still be invisible inside the AI answer.
Layer 1: AI Overview presence and citation share
Take your priority queries and log, manually or with a tool, which ones now trigger an AI Overview and whether you are one of the cited sources. This gives you two numbers worth tracking over time: your presence rate (how often an Overview appears for your terms) and your citation share (how often you are in it). Tools such as Ahrefs Brand Radar and various AI-visibility checkers automate this across engines.
Layer 2: AI referral traffic in GA4
Answer engines rarely hand over clean referral data, and by default GA4 makes it worse - much AI-assistant traffic lands in Direct or Referral rather than a channel of its own. To see it properly, set up a custom channel grouping that captures hosts like chatgpt.com, perplexity.ai, claude.ai and gemini.google.com (OpenAI now appends a utm_source=chatgpt.com tag, which helps). Then watch for branded-search spikes, which often signal that people discovered you in an AI answer and searched for you directly. Volumes will be modest at first - the signal is the trend and the conversion quality, not the raw number.
Layer 3: share of model
This is the AI-era equivalent of share of voice. Build a fixed set of buyer-intent prompts - the questions a customer would actually ask, such as "best managed IT provider in London" or "is [your brand] any good" - and run them across ChatGPT, Perplexity and Gemini on a regular cadence. Run them repeatedly rather than once: AI answers are volatile, with one study finding just 9.2% of cited URLs stayed consistent across repeated searches (SE Ranking), so a single screenshot proves nothing. Count how often you are cited versus named competitors. Tracked monthly, that becomes a clear, comparable measure of whether your AEO work is landing.
One caveat on the data: AI Overview answers are getting shorter - seoClarity recorded average length falling by around 70% over a single month - which means fewer citation slots per answer. Expect citation share to be competitive, and treat being cited at all as a meaningful win.
AEO for UK businesses: where to start
Start with the fundamentals that help in both classic and AI search: make sure AI bots can crawl you, rewrite your most important pages to be answer-first, add the right schema, and shore up your entity and reviews. You do not need a separate "AI strategy" so much as a modern SEO approach that takes citations as seriously as rankings.
For most UK SMEs and mid-market firms, the sensible sequence is:
- Audit your exposure. Which priority queries now show AI answers, are you cited, and can the AI bots even reach your content?
- Fix crawlability. Unblock the AI crawlers you want, and get critical content out from behind JavaScript.
- Rewrite your top pages answer-first. Lead with the answer, add statistics and named sources, tidy the heading hierarchy.
- Add schema. Article, FAQPage and HowTo on the relevant pages; Organisation and LocalBusiness to reinforce your entity.
- Build authority off-site. Reviews, useful community contributions and earned coverage on the sources AI engines trust.
- Measure and iterate. Track presence, citation share and AI referral conversion, and double down on what gets cited.
We practise what we sell
We're a UK technology consultancy, and we build AEO into our own work rather than just writing about it. Red Eagle Tech's content is already cited in Google AI Overviews for SEO questions, this very page is built to the answer-first, schema-marked, information-dense spec it describes, and our engineering background means we build the technical side - schema, entities, AI-readable architecture - in-house rather than outsourcing it. When we recommend the durable fundamentals over silver-bullet tactics like paid llms.txt schemes, it's because that's how we get cited ourselves.
Our SEO service folds AI and GEO optimisation into every plan with no AI surcharge, starting from £750 per month, and most engagements begin with a £397 audit that now includes an AI-visibility assessment. We publish our pricing - which most AEO and GEO agencies still won't - we explain our methods, and we'll tell you honestly where AEO will and won't make a difference for your business. For the full pricing picture, our guide to how much SEO costs in the UK breaks down every tier, and if your focus is local visibility, see our guide to local SEO for small businesses.
Want to know how AI answer engines see your business? Our SEO and AI-visibility service starts with an audit of where you stand in AI Overviews, ChatGPT and Perplexity - and a clear, jargon-free plan to earn more citations. No AI surcharge, transparent pricing, no long lock-in.
The 6-12 month outlook
Over the next 6-12 months, expect AI answers to spread further into commercial and comparison queries, to get shorter and more selective about citations, and the terminology to consolidate around "AI SEO" for the mass market and "AEO" or "GEO" for specialists. The businesses that win will be those that treat AEO as durable fundamentals rather than a fad.
A few trends look fairly safe to bet on:
- AI answers move down the funnel. Overviews started on informational queries; they're steadily appearing on commercial and comparison searches - Ofcom already records AI Overviews on up to 34% of non-branded UK searches - which is where the revenue is. Expect more of your money-keyword SERPs to gain an AI answer.
- Answers get shorter and citations scarcer. With AI Overview length already compressing sharply, there will be fewer citation slots per answer. Being the single clearest source on a question matters more, not less.
- Measurement matures. AI-visibility tracking is becoming a standard part of the reporting stack alongside Search Console and GA4. Expect "citation share" to sit on dashboards next to rankings within a year.
- The labels converge. The acronym churn will settle. "AI SEO" looks set to win as the everyday term, with AEO and GEO persisting in specialist and strategic use.
- The fundamentals stay stable. Through all of it, the things that earn citations - clear answers, real evidence, structured content, genuine authority - are the same things that have always made good content. That is the reassuring part.
The takeaway for UK businesses is not to panic or to chase every new acronym. It's to build content and technical foundations that serve both the blue links and the AI answer - because the durable work pays off in both, and the hype-driven shortcuts pay off in neither.

Frequently asked questions
Answer engine optimisation (AEO) is the practice of structuring content so AI answer engines - Google AI Overviews, ChatGPT, Perplexity, Gemini and Copilot - can extract, trust and cite it in their generated answers. The win condition is being quoted as the answer, not just ranking in a list of links. AEO leans on answer-first writing, information density, structured data and third-party authority.
SEO optimises to rank in a list of links. AEO (answer engine optimisation) and GEO (generative engine optimisation) both optimise to be cited inside an AI-generated answer. AEO and GEO describe the same job under different labels - GEO came from a 2024 Princeton study, AEO is the more common UK agency term. You still need SEO underneath, because AI engines draw most citations from pages already ranking in the top 20 organic results.
For practical purposes, yes. AEO, GEO and LLM SEO all describe getting your content cited inside AI-generated answers. The differences are branding, not method: GEO is favoured by specialists and academia, AEO by UK agencies and LLM SEO by engineering-led teams. "AI SEO" is the broad mass-market label. The underlying work - answer-first content, schema, entities and earned third-party mentions - is the same across all of them.
Be the clearest, most citable source on the question your customers ask. In practice that means: open pages with a direct 40-60 word answer, add concrete statistics and named sources, allow GPTBot in your robots.txt, make sure content is not hidden behind JavaScript, and earn mentions on third-party sites ChatGPT trusts (industry publications, review sites, Reddit). ChatGPT favours brands that are recognised entities with consistent signals across the web.
Rank in the top 20 organic results first - seoClarity found around 97% of AI Overviews cite at least one source from the top 20, though even the number-one page is only cited about 43% of the time. Then make your content extractable: answer the question in the first 150 words, use clean heading hierarchy, add FAQ and Article schema, and pair claims with numbers and sources. Being cited can lift click-through by around a third even when an Overview sits above you.
Yes. AEO sits on top of SEO, it does not replace it. AI answer engines overwhelmingly cite pages that already rank well - in one large study, around 97% of AI Overviews cited at least one source from the top 20 organic results. If you are not indexed, crawlable and reasonably well-ranked, there is nothing for an answer engine to cite. Strong technical SEO, relevant content and authority are the foundation AEO builds on.
There is no evidence it does yet. llms.txt is a proposed file that tells language models where your key content sits, but no major AI provider has committed to reading it. Ahrefs found that 97% of valid llms.txt files received zero requests in May 2026, and Google's John Mueller said it is "not done for search". Treat it as optional experimentation. The proven levers are answer-first content, schema, allowing AI bots in robots.txt and earning third-party mentions.
Track three things. First, AI Overview presence and citation share: log which of your priority queries trigger an Overview and whether you are cited. Second, AI referral traffic in GA4: filter for visits from chatgpt.com, perplexity.ai and gemini.google.com. Third, share of model: run a fixed set of buyer-intent prompts in ChatGPT, Perplexity and Gemini on a regular cadence and count how often your brand is cited versus competitors. Tools like Ahrefs Brand Radar automate parts of this.
The early data says it converts well. Similarweb found ChatGPT referrals convert at 11.4% versus 5.3% for organic search - more than double. The likely reason is intent: someone who clicks a citation inside an AI answer has already had their question partly answered and is further down the funnel. Volumes are still modest for most UK businesses, but the per-visit value of AI referral traffic appears higher than standard organic.
AEO isn't usually a separate line item - it's part of a modern SEO retainer. UK SEO retainers typically run £500-£5k per month depending on competition and scope. At Red Eagle Tech, AI and GEO optimisation is included in our monthly SEO plans from £750 with no AI surcharge, and most engagements start with a £397 audit. For a full breakdown of UK pricing, see our guide to how much SEO costs in the UK.
Google AI Overviews matter most by reach, because they sit on top of the search most UK users already do - Ofcom reports around 30% of UK searches now show an AI summary. ChatGPT matters most for high-intent research and converts well. Perplexity is growing fast among B2B and technical buyers. The good news is that the same fundamentals - answer-first content, schema, entities and third-party authority - improve your standing across all of them at once.
Faster than traditional SEO for low-competition questions, slower for competitive ones, because AEO still depends on your organic ranking. Pages that already rank can start appearing in AI answers within weeks of being restructured to be answer-first. Building the entity signals and third-party authority that earn consistent citations takes months. Expect early wins on niche questions in 4-8 weeks and meaningful citation share over 3-6 months.
Yes, and arguably more easily than in classic SEO. AI engines reward the clearest, best-structured answer to a specific question, not just the biggest domain. A small UK firm that publishes a genuinely useful, well-sourced, answer-first page on a narrow topic can be cited alongside far larger competitors. Niche, specific questions are where smaller businesses win citations, because there is less authoritative content competing for them.
The label is partly hype - much of AEO is good SEO and content practice with a new name. But the shift it responds to is real: AI answers now intercept a large share of clicks, and being cited is becoming a genuine discovery channel. The sensible position is to do the durable fundamentals (clear answers, structured data, real authority) that help you in both classic and AI search, and ignore the silver-bullet tactics like paid llms.txt schemes.
Answer the question directly, early and with evidence. The Princeton GEO study found that citing credible sources, adding statistics and including quotations were the biggest levers for AI citation, lifting visibility by 30-41%. If you open each section with a clear 40-60 word answer backed by a named source and a number, you have done most of what matters. Everything else - schema, entities, crawlability - amplifies a page that already answers the question well.
