What Is an AEO Agency?
An AEO agency does answer engine optimisation: it structures your expertise so machines lift it straight into the answer, instead of leaving you as a link somebody has to click. MarGen is a UK AEO agency, based in Sheffield and working with businesses across the country.
The shift is simple to state and awkward to live with. A buyer used to type a query, scan ten links, and choose. Increasingly they ask a question — of Google, of ChatGPT, of Copilot inside the tools they already work in — and receive an answer with two or three businesses named in it. If you are not one of them, the ranking beneath that answer is decoration. AEO is the work of being named.
AEO, GEO, AI SEO: Which Do You Actually Need?
These three terms get used interchangeably, and the confusion is costing people money. The honest version:
| What it targets | Where you see it | |
|---|---|---|
| AEO — answer engine optimisation | Winning the direct answer | Google AI Overviews, featured snippets, voice results |
| GEO — generative engine optimisation | Being cited inside a generated answer | ChatGPT, Perplexity, Gemini, Claude |
| AI SEO | The umbrella most buyers search for | All of the above |
The underlying engineering is roughly eighty per cent shared. Entity clarity, structured data, answer-first content and third-party corroboration serve all three. This is why MarGen delivers them as one engagement rather than three invoices — and why you should be sceptical of anyone selling AEO as a separate product line with its own retainer.
If you want the fuller distinction, we wrote it up in AEO vs GEO vs SEO and what AEO actually means.
What the Engagement Involves
Four workstreams, run in parallel rather than in sequence.
1. Prompt and question mapping
We map what your buyers actually ask, in their words. Not keywords — questions. “Who handles FCA-compliant marketing for wealth managers” is a different problem to the keyword “financial services marketing”, and it is what people now type. This is also where we find the questions you answer better than anyone and have never written down.
2. Answer-first rebuilding
Most business content buries its answer under three paragraphs of context. Machines do not wait. We restructure so the direct answer comes first, the evidence sits underneath, and the whole thing is marked up — FAQ, HowTo, Article, Organisation — so a model can parse it without guessing.
3. Entity and citation building
A model will not name a business it cannot verify. That means consistent entity signals across the sources models actually read, named authors with traceable credentials rather than anonymous company bylines, and third-party corroboration that exists somewhere other than your own website. This is the slowest part and the one that compounds.
4. Measurement against competitors
We track which answers cite you, which cite someone else, and how that moves. Citation share, not a vanity keyword position. You will know the specific questions where a competitor is being named instead of you, which is usually the thing that makes the case internally.
The framework behind all four is the Synaptic Authority Engine, our six-step process.
Why a Specialist Rather Than Your Current SEO Agency
Most full-service agencies have added “AEO” to a service page and carried on doing what they did before. That is not cynicism, it is incentives — the work rewards a different skill set, and rebuilding a delivery model is expensive.
The practical difference: traditional SEO optimises for a position in a list, and gets there largely through domain authority and link volume. AEO optimises to be the extracted answer, and gets there through claim precision, structure and verifiable expertise. A focused specialist can be cited alongside far larger brands, because models weigh entity clarity more heavily than domain size. That asymmetry is the opportunity, and it does not last forever.

AEO for Regulated Sectors
Answer engines are unusually well suited to regulated businesses, because they reward what compliance already forces you to do: state claims precisely, attribute them to named people, and cite sources.
The real constraint is approval. Copy needs sign-off, and a process that ignores that will stall in month two. We build the approval loop into the engagement rather than treating it as friction, and we price regulated work accordingly. Sector detail: financial services, legal, healthcare.
What It Costs
MarGen publishes pricing rather than quoting case by case.
| Free AI Visibility Audit | An automated read of your public signals and where you currently stand |
| Synaptic Audit — £2,950 | The full diagnostic. Credited against your first month if you continue |
| Foundation — £2,950/mo | 90-day on-ramp: entity baseline, answer-first architecture, monthly tracking |
| Authority — £5,950/mo | Multi-platform, third-party citation building, weekly tracking. £6,500 regulated |
| Dominance — from £12,950/mo | Every major AI surface, real-time monitoring, competitive displacement |

How Long Before Anything Happens
Structural work surfaces fastest. Schema, answer-first rewrites and entity cleanup remove things that were actively preventing extraction, and that can show within weeks.
Citation authority is slower — typically three to six months — because it depends on third-party corroboration accumulating, and you cannot rush other people publishing about you. Anyone promising AI citations inside thirty days is describing an outcome they do not control. More on the realistic curve: how long GEO takes to work.
Start With the Free Audit
The first useful thing is finding out what AI already says about you, which most businesses have never checked. Our free AI Visibility Score reads the same public signals the models use and names the gaps, in about a minute. No email needed to see your score.

Common Questions About AEO Agencies
What is an AEO agency? An AEO agency does answer engine optimisation: it structures your expertise so that AI systems and search engines lift it directly into the answer they give a buyer, rather than leaving you as a link somebody has to click. That means engineering answer-first content, structured data, and the entity and citation signals a model needs before it will name you. MarGen is a UK AEO agency, based in Sheffield and working nationwide.
What does a UK AEO agency actually do day to day? Four things. It maps the questions your buyers put to AI tools and search engines, in their words rather than yours. It rebuilds your content so the answer is extractable — a direct response first, evidence underneath, marked up so machines can parse it. It builds the third-party corroboration that makes a model confident enough to quote you. Then it monitors which answers cite you and which cite a competitor instead, and closes the gap.
What is the difference between AEO, GEO and AI SEO? AEO is about winning the direct answer — featured snippets, Google AI Overviews, the response an assistant reads aloud. GEO is about being cited inside longer generated answers from ChatGPT, Perplexity, Gemini and Claude. AI SEO is the umbrella term most buyers actually search for. The underlying work overlaps almost entirely, which is why MarGen delivers them as one engagement rather than three invoices.
How much does an AEO agency cost in the UK? MarGen publishes its pricing rather than quoting case by case. Engagements start with a free AI Visibility Audit, then a £2,950 Synaptic Audit which is credited against your first month. Retainers run from £2,950 a month for Foundation, £5,950 for Authority (£6,500 in regulated sectors) and from £12,950 for Dominance. Our AEO pricing guide breaks down what the wider UK market charges and why.
How long does AEO take to show results? Structural wins — schema, answer-first rewrites, entity cleanup — can surface in weeks, because they remove things actively preventing extraction. Citation authority takes longer, typically three to six months, because it depends on third-party corroboration accumulating. Any agency promising AI citations in thirty days is describing something they cannot control.
Does AEO work for regulated businesses? It tends to work better, because regulated sectors reward exactly what AEO produces: precise claims, named and credentialed authors, and traceable sources. The constraint is approval — copy usually needs compliance sign-off, so the process has to be built around that rather than fighting it. MarGen works with financial services, legal and healthcare firms and prices regulated engagements accordingly.
Can I do AEO myself instead of hiring an agency? The technical layer, yes — schema markup and answer-first formatting are learnable, and our guide to answer engine optimisation covers the principles. What is harder to do alone is the third-party citation building and the ongoing measurement of which AI answers name you, because both need tooling and sustained effort rather than a one-off project.
