UK AEO and GEO agency for AI search visibility
We work on how your brand is selected, cited and described when buyers ask AI for recommendations. Answer engine optimisation and generative engine optimisation, run as one programme for UK brands.
We run this on ourselves first
We are an AEO agency in a category where buyers ask AI which AEO agency to use. That makes us our own test case, so we track it the same way we track a client and publish what it says.
Across the prompts buyers use to find agencies like us, Tilio holds 27.1% visibility and 5.9% share of voice, ranking first in the tracked set as at July 2026.
It is the same measurement work we set up for you: a real prompt set, real answer engines, tracked over time rather than sampled once.

Scope: Measured across ChatGPT, Google AI Overviews and Perplexity in the United Kingdom, against our own tracked prompt set for the UK AI search agency category as at July 2026. Competitors are anonymised. This is one category and one prompt set, not every AI answer in every market. We publish the method on our How we measure AI visibility page so the claim can be checked rather than taken on faith.
Terminology
What AEO and GEO mean at Tilio
Two terms, one programme. The distinction is real, but it is not a distinction between two things you can buy.
GEO and AEO are two terms for one Tilio programme. AEO focuses on how your brand is selected, cited and described in individual AI answers. GEO covers the wider system behind those answers, including retrieval, source quality, technical accessibility and third-party corroboration. We do not sell them as separate services.
The practical reason they are one programme is that neither half works alone. Fix your pages and you may still be absent from the answer because the third-party sources the engine reads never mention you. Get mentioned across the category and it does you no good if the page the engine lands on does not say what you actually sell.
If you have been quoted for one and not the other, you have been quoted for half the job.
Diagnosis
Why brands disappear from AI recommendations
Absence is rarely one problem. In the accounts we baseline, it is usually three or four of these at once, and the order you fix them in decides how quickly anything moves.
The engine cannot tell what you are
Your category, your offer and your name are stated differently across your site and the web. An engine that cannot resolve you to one clear entity will reach for a competitor it can.
Your commercial pages do not answer the question
Service and pricing pages written to persuade rather than to inform give an engine nothing extractable. If the answer to what something costs or who it suits is not on the page, it cannot be quoted from the page.
Claims arrive without evidence
Assertions with nothing behind them are weak source material. Specifics, figures, named methods and dated statements are what make a page worth citing rather than paraphrasing.
Something technical is blocking retrieval
Content rendered only in the browser, blocked crawlers, redirect chains and thin templates all stop a page becoming a source, however good the copy on it is.
The sources the engine reads do not mention you
Answers to who should I use questions are built largely from third-party pages: directories, roundups, editorial and community threads. If your competitors appear there and you do not, your own site cannot close that gap on its own.
Tilio's four-layer approach
Most AEO work starts with content. We start with measurement, because you cannot improve an answer you have not read. Four layers, run in order, each one informed by the last.
Analytics
We build a prompt set around your services, buyers, competitors and decision-stage questions, then track it across ChatGPT, Perplexity and Google AI Overviews. You get a baseline before anything changes: where you are mentioned, where you are cited, which of your pages AI actually reads, which competitors appear instead of you, and what position you hold when you do appear. Every later decision is made against this baseline.
Content
We fix the pages AI engines reach for and ignore the ones they never touch. That means answer-ready structure, extractable definitions, comparison and alternatives pages, sector and location pages, and consistent entity signals across your site so AI systems describe you the same way every time. Prioritised by what the Analytics layer shows is actually being retrieved.
Factcheck
Visibility is only half the problem. The other half is being described wrongly: outdated pricing, services you no longer offer, claims attributed to you that were never yours, or a competitor's positioning applied to your brand. We monitor what AI platforms assert about you, flag inaccuracies, and work on the sources feeding them. Wrong pricing is the most common and most costly error we find, because it propagates: one stale third-party page becomes the figure every assistant quotes.
Source Ecosystem
AI answers to “best GEO agency” questions are built largely from third-party pages, not from your own site. We identify which external pages AI engines actually read for your category, which of them your competitors appear on and you do not, and work to close that gap through submissions, directories, editorial and community presence. This is the layer most GEO providers skip, and it is usually where the biggest gains are.
The four layers map onto our four pricing levels cumulatively, so you can start at the measurement layer and add the rest as the work earns it. See what each level includes.
Outcomes
What the programme improves
Six things, measured from the start so the direction is visible month to month rather than argued about at the end of a quarter.
Mentions
How often you are named at all when buyers ask the questions that matter commercially.
Citations
Whether the answer links to you as a source, which is the difference between being described and being credited.
Citation quality
Which of your pages gets cited. A pricing question answered from a two-year-old blog post is a worse outcome than the same question answered from your pricing page.
Accurate descriptions
Whether what the engine says about your services, your prices and your coverage is actually true. Wrong pricing is the most common error we find and the most expensive to leave alone.
Competitor comparison performance
How you fare in the head-to-head questions: who is best for, alternatives to, and X versus Y. These are the prompts closest to a decision.
Commercial buyer-intent visibility
Presence on the questions with budget behind them, rather than a high score on questions nobody buys from.
Answer surfaces
Platforms we optimise for
Tracking runs across ChatGPT, Google AI Overviews and Perplexity as standard, and up to ten answer engines on managed programmes.
Google AI Overviews
Improve the likelihood of selection and citation through better coverage, structure and evidence. This is the surface where the work overlaps most with technical SEO.
AI assistants including ChatGPT
Improve how your brand is described and when it is recommended, by strengthening entity clarity and the third-party signals assistants lean on.
Citation-led engines such as Perplexity
Increase the likelihood that your pages are referenced as sources, through evidence-led content and clean structure.
Google AI Mode and conversational search
Support follow-up questions, comparisons and decision-stage queries with answers complete enough to survive being asked twice.
Accuracy-first AEO
Citation Fidelity by Tilio
For some brands, visibility is only part of the job. The bigger challenge is making sure AI platforms pick up the right information, describe it accurately, and cite the most trustworthy source.
It is our accuracy-first approach to AEO for brands where incorrect AI answers carry real risk, including healthcare, finance, legal, cybersecurity, insurance, and other regulated or sensitive sectors.
AEO helps you get mentioned. Citation Fidelity helps AI systems cite the right source and repeat the right facts.
What Citation Fidelity focuses on
For high-stakes topics, we look beyond whether your brand appears in AI answers. We also look at how your information is retrieved, summarised, attributed, and repeated.
- Which page is the canonical source for an important claim.
- Which facts are current, verified, and safe to repeat.
- Which pages need stronger structure, clarity, or review signals.
- Where third-party descriptions are creating confusion or drift.
- How consistently your brand is being cited across AI platforms.
What this looks like in practice
We strengthen the pages and signals that support accurate retrieval. For brands in sensitive or regulated spaces, this helps reduce answer drift, improve citation quality, and increase the chances that AI platforms rely on the right source when your brand is mentioned.
- Clearer source-of-truth pages for high-risk claims.
- Tighter claim wording to reduce ambiguity and misinterpretation.
- Stronger internal linking to reinforce authority pathways.
- Improved page structure for cleaner extraction and summarisation.
- Expert review signals and cleaner corroboration across the web.
When this matters most
Citation Fidelity is especially useful when your category depends on precision. In healthcare, inaccurate summaries, outdated information, or weak source selection can do more than hurt visibility. They can undermine credibility.
That is why we treat answer quality, source accuracy, and citation reliability as part of the job in every engagement.
AEO and SEO
AEO versus SEO
AEO depends on SEO. It is measured differently, and it is not a replacement for it.
The technical foundations are shared. Crawlability, indexation, internal links, site structure, page quality and schema all still matter, and a page an engine cannot reach or parse is not a candidate for anything. Good SEO makes AEO possible.
What differs is the question being asked of the page. SEO asks whether it ranks. AEO asks whether it can support a clear answer, and whether an engine would trust it enough to cite. Those are not the same bar, which is why pages that rank well can still be absent from the answer above them.
The measurement differs with it. SEO reports on rankings, impressions, clicks and traffic. AEO reports on visibility across a prompt set, mention and citation rates, which competitors appear instead of you, and whether what is said about you is accurate.
An SEO agency helps you rank. A specialist AEO agency works on whether you appear inside the answer itself. Most teams need both, and many keep their SEO agency alongside us.
Fit
Who the programme is for
It suits teams that want the work delivered and reported, rather than another dashboard to interpret on their own.
B2B brands
Where a single deal justifies the work, and where buyers research through AI long before they fill in a form.
In-house marketing teams
Teams that want AI visibility handled properly without building the function, the tooling and the tracking from scratch.
SEO teams
Specialists who know their site and want the answer-engine layer measured and worked on alongside what they already run.
Agencies needing specialist support
Where your client work needs an AEO layer behind it and hiring for it does not yet make sense.
Leadership teams managing AI-search risk
For whom the question is not only whether you appear, but what is being said about you when you do, and what happens if it is wrong.
Delivery model
How the work runs, and what reporting looks like
One operating rhythm: measure, prioritise, implement, report. The same cycle every month, so progress is comparable rather than anecdotal.
Each cycle includes:
- Prompt and topic tracking against your priority commercial questions
- A prioritised action plan based on what the answers actually show
- Content and technical work implemented, not just recommended
- Monitoring of how you are described, and correction at the source where it is wrong
- Monthly reporting on visibility, citation quality and outcomes
Reporting is written to be forwarded. Each cycle shows what was limiting visibility, what changed across technical, content, factcheck and source work, and what moved as a result. Where it is useful we include the before and after for a specific prompt, so the change is something you can read rather than take on trust.
Your questions, domains and competitive context are treated as sensitive by default. Delivery runs on a SOC 2 compliant platform with encryption in transit and at rest, controlled access, and separation between client workspaces.
UK delivery
UK-focused AEO and GEO, based in Exeter
We work with UK brands on the searches that carry commercial intent, not on visibility in general.
From our base in Exeter we support teams across the UK, with measurement set up for the UK region and prompt sets built around how British buyers actually phrase things.
That means the questions asked close to a decision: what something costs, which alternatives exist, how two providers compare, and who suits a particular brief. Those are the answers worth appearing in.
For the broader UK overview, our AI SEO for UK businesses page explains where most teams should start.
Start with the right route
Most teams start with the audit, because it answers whether there is a problem worth paying to fix. There is no obligation to continue into a programme afterwards.
AI Visibility Audit
A fixed-price baseline with the raw data and a 90 day plan. The right start when you need evidence before committing to ongoing work.
AI Search Content Sprint
For teams that already know which pages are weak and want them rebuilt properly, without a retainer.
Ongoing AEO and GEO programme
Implementation and monitoring across all four layers, at the level that fits. Four levels from £499 a month.
FAQs
What is an AEO agency?+
An AEO agency works on how your brand is selected, cited and described inside AI-generated answers, rather than on where your pages rank in a list of links. In practice that means tracking a prompt set across answer engines, analysing which pages get used as sources, benchmarking the competitors who appear instead of you, and improving the pages and signals that decide selection.
Is GEO the same as AEO?+
They are two terms for one job, and at Tilio they are one programme. AEO looks at the individual answer: whether you are named, cited and described correctly in it. GEO looks at the system that produces those answers: retrieval, source quality, technical accessibility and third-party corroboration. Anyone selling you one without the other is quoting for half the work.
Can AEO improve ChatGPT visibility?+
It can improve the conditions that make a mention more likely, and that is the honest limit of it. Nobody can set what ChatGPT says. What can be changed is whether your pages are reachable and readable, whether your offer is stated clearly enough to be extracted, whether claims are backed by evidence, and whether the third-party sources ChatGPT reads for your category describe you at all.
Can AEO improve Google AI Overviews visibility?+
Yes, and the work overlaps more with technical SEO here than on any other surface. AI Overviews draw on Google's existing index, so crawlability, page structure, clear headings and evidence for claims all feed selection. Google's own guidance says search fundamentals still apply to its AI features, so this builds on SEO rather than replacing it.
How does Tilio measure AI visibility?+
Through a prompt set built around your buyers and tracked over time across answer engines, recording where you are mentioned, where you are cited, which of your pages are used as the source, which competitors appear instead of you, and how you are described when you do appear. The method is published so a claim can be checked rather than taken on trust.
How long does AEO take?+
It depends on where you are starting. Where pages are unclear or something technical is blocking retrieval, movement can come quickly. Broader visibility builds over months as pages are updated, re-crawled, cited and reinforced by stronger third-party sources. We report monthly so the direction is visible well before the destination is.
Do you guarantee AI mentions or citations?+
No, and you should be wary of any agency that does. AI answers vary by platform, prompt, location, timing and what has been published since the last run. What we commit to is the work that improves the odds, and reporting honest enough that you can see whether it is landing.
Is Tilio an AEO agency or a GEO agency?+
Both, because they are the same programme. We use AEO as the primary term because it names the measurable outcome, and GEO describes the wider system we work on to get there. You are not choosing between two services or two prices.
