Enterprise GEO is generative engine optimisation run across a portfolio rather than a single site. Multiple brands, multiple regions, multiple product lines, each with its own entity, its own query universe and its own competitors, coordinated so that they reinforce one another instead of competing for the same answer.
The technical work is not fundamentally different from single-site GEO. What changes is everything around it: entity architecture across related brands, governance, stakeholder alignment, and the fact that nothing ships until legal, compliance, InfoSec and procurement have each had their turn.
The Enterprise-Specific Problem
Most of what a large organisation needs from GEO is what a small one needs, done more times. One problem, though, only appears at scale, and it is usually the one costing the most.
AI systems cannot tell your brands apart, or cannot tell they are related.
A typical enterprise portfolio has a parent brand, several acquired sub-brands trading under their original names, regional entities with slightly different legal names, and a product line whose name collides with a generic industry term. To a language model this is not a portfolio. It is a cluster of weakly connected, partially duplicated entities, some of which get conflated with each other and some of which get conflated with a competitor.
The symptoms are recognisable once you know to look for them. Ask a model about your parent brand and it describes a sub-brand’s products. Ask about a regional entity and it answers about the group. Ask about the product line and it answers about the generic term. Ask which company owns a brand you acquired three years ago and it names the previous owner, because that is what the corroborating sources still say.
None of that is fixed by publishing more content. It is fixed by entity architecture: deciding what each entity is, marking that up consistently, connecting them with explicit relationships, and then correcting the third-party sources the models are actually drawing on. It is the first domain of the Synaptic Authority Engine and at enterprise scale it is usually where the entire return sits.
What An Enterprise Engagement Covers
Everything in the Authority tier, run across multiple fronts simultaneously, plus the things only portfolio scale requires.
Portfolio entity architecture. A single map of every brand, region and product line: what it is, how it relates to the others, what it is called canonically, and where the current corroborating sources are wrong. Marked up in structured data, published as an on-site entity hub, and pushed out to Wikidata and the Knowledge Panel where they exist.
Per-front query universes. Each brand and region gets its own query set and its own competitor list, because “our competitors” at group level is rarely the same list as the one a buyer in one region for one product line would encounter.
Citation share measurement, reported per front. Tracked across ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews, against named competitors, over time. Reported separately by brand rather than aggregated, an aggregate at portfolio scale will hide a brand going backwards behind two brands going forwards.
Off-site authority at scale. The domains AI systems already cite for your categories, worked deliberately. This is the slow, expensive half of GEO and it is the half that decides outcomes.
Active competitor displacement. Identifying where a named competitor currently owns the answer, and running a specific programme to take that position rather than hoping for it.
Done-with-you enablement. Most enterprises intend to bring some of this in-house eventually. Dominance-tier engagements include team enablement, and the methodology is published in full rather than held as a black box, because an arrangement that only works while you cannot see inside it is not one worth signing.
Working Alongside Your Existing Agencies
MarGen is a specialist. It does not sell paid media, web development or brand work, and it is not trying to become your lead agency. In practice almost every enterprise engagement runs alongside an incumbent SEO or media roster.
That overlap is real and partial, so it gets drawn explicitly at the start:
| Typically MarGen | Typically your incumbent |
|---|---|
| Entity architecture and knowledge-graph work | Traditional ranking and keyword strategy |
| Structured data and schema standards | Technical SEO at scale, Core Web Vitals, crawl budget |
| Answer-first content restructuring | The wider content calendar and production |
| AI citation tracking across five platforms | Rank tracking and classic organic reporting |
| Digital PR aimed at AI-cited source domains | Brand PR and wider earned media |
Agencies that already understand GEO tend to welcome this, because the specialist workstream makes their numbers better. Where an incumbent objects, it is worth asking them what their AI citation measurement currently shows. The answer is informative.
If your agency has not raised AI search with you at all, that is its own signal: what to do when your SEO agency isn’t doing GEO.
Procurement, Security and the Honest Part
Enterprise buying has gates, and it is faster for everyone if the awkward ones are cleared in the first conversation rather than the fourth.
What MarGen does routinely: security questionnaires, data processing agreements, named-personnel restrictions, least-privilege access to analytics and CMS, working inside your change-control process, and delivery that fits a compliance approval cycle rather than fighting it.
What MarGen does not currently hold: ISO 27001 or SOC 2 certification. MarGen is a small specialist firm, not a large vendor, and it would rather say so on a web page than at the end of a procurement process. If a certification is a hard gate in your organisation, establish that early. There are enterprises for whom it is absolute, and no amount of good work makes that go away.
What that structure buys you is the other side of the same coin: senior people on the work rather than on the pitch, no account-management layer between you and the person doing the thinking, and a firm that has no larger service line to grow into your budget from underneath.
Pricing
| Step | Investment | Term |
|---|---|---|
| Free AI Visibility Audit | Free | , |
| Synaptic Audit | £2,950 one-off, credited against your first retainer month | , |
| Authority | £5,950 / month (£6,500 regulated or multi-product) | 12 months |
| Dominance, the enterprise tier | From £12,950 / month, scoped bespoke | 12 months |
Dominance is priced by the number of fronts (brands, regions, product lines) rather than by a feature list, because that is what actually drives the cost.
Not every portfolio is a commercial group. A university with several faculties, a trust with multiple operating brands, or a group with regional trading entities has the same structural problem under a different name, which is why the sector version of this page, GEO for universities and higher education, is scoped the same way.
Most enterprise engagements should start with the Synaptic Audit rather than the retainer. It proves the model on one front, produces the portfolio entity map, and gives you something concrete to take to the budget conversation. The fee is credited in full against the first retainer month if you proceed within 30 days, so running it first costs nothing but time.

Measurement, and Why the Usual Reports Mislead
One thing worth flagging before the first board update, because it catches people out.
At enterprise scale you will have pages ranking on page one with four-figure impressions and close to zero clicks. On a standard organic report those look like failures. Frequently they are the opposite: an AI Overview is answering the question in place, using your content, and the user never needs to click. The brand was cited. The click was not the point.
Judging GEO on click-through rate will therefore systematically undervalue the work that is going best. MarGen reports citation share by platform and by front as the primary measure, with organic metrics as context rather than as the verdict. If your internal reporting is CTR-led, that conversation is worth having in month one rather than month four.

Regulated Portfolios
If any part of the portfolio is FCA, SRA or CQC regulated, the compliance layer is not optional and the timeline reflects it. Copy needs sign-off. Claims need substantiation on request. An unsubstantiated performance claim is a regulatory exposure, not merely marketing overreach, which is one reason MarGen does not offer guaranteed outcomes to anyone.
It is also the sector where AI misrepresentation costs most. A model confidently stating the wrong thing about a regulated product is a compliance incident with a marketing cause, and the people who own that risk are usually easier to get budget from than the people who own the content calendar.

Enterprise GEO: Common Questions
What is enterprise GEO?
Enterprise GEO is generative engine optimisation run across a portfolio rather than a single site: multiple brands, multiple regions or multiple product lines, each with its own entity, its own query set and its own competitors, coordinated so they reinforce rather than cannibalise one another. The technical work is the same as single-site GEO. What changes is the coordination, the governance and the fact that decisions have to survive legal, compliance and procurement before anything ships.
How is enterprise GEO different from enterprise SEO?
Enterprise SEO optimises for position in a ranked list. Enterprise GEO optimises for being named inside a generated answer, where there is no list and typically two or three brands get mentioned at all. The practical difference at enterprise scale is entity architecture: a large organisation usually has a parent brand, several sub-brands and regional entities that AI systems either conflate or fail to connect. Resolving that is the enterprise-specific problem, and it does not arise on a single-site engagement.
How much does enterprise GEO cost?
MarGen’s Dominance tier starts at £12,950 per month on a 12-month minimum and is scoped bespoke, because the cost is driven by the number of fronts (brands, regions, product lines) rather than by a feature list. Most enterprise engagements begin with the £2,950 Synaptic Audit, which proves the model on one front before the full programme is committed, and is credited in full against the first retainer month.
Will MarGen replace our existing SEO or media agency?
No, and it is usually a mistake to try. MarGen is a specialist that runs the GEO and AEO workstream alongside an incumbent roster, and most enterprise engagements are structured that way. The overlap with the SEO agency is real but partial, so the boundary gets drawn explicitly at the outset, typically MarGen owns entity architecture, structured data, answer-first restructuring and AI citation measurement, while the incumbent keeps traditional ranking work, technical SEO at scale and the wider content calendar.
Can MarGen work within our security and procurement requirements?
Yes. Enterprise engagements routinely involve a security questionnaire, a DPA, named-personnel restrictions and least-privilege access to analytics and CMS. MarGen is a small specialist firm rather than a large vendor, so it will tell you plainly what it does and does not hold: it is not currently ISO 27001 or SOC 2 certified. If a certification is a hard procurement gate, that is worth establishing in the first conversation rather than the fourth.
How do you measure enterprise GEO?
Citation share by brand, by query set and by AI platform, tracked over time against named competitors, and reported per front rather than rolled into one number. That matters at portfolio scale because an aggregate can hide a brand going backwards. The measurement problem is genuinely harder than in SEO, a page-one result earning zero clicks may be an AI Overview answering in place, which looks like failure on a CTR report and is not.
How long does an enterprise programme take to show results?
Structural wins (entity resolution, schema, answer-first restructuring) surface within weeks on the fronts where something was actively blocking extraction. Citation share moves over three to six months because it depends on third-party corroboration accumulating. At enterprise scale expect the first fronts to move before the last, and plan the reporting narrative around that rather than waiting for the portfolio to move at once.
What if our brands are in a regulated sector?
That is the case MarGen is built around. Financial services, legal and healthcare work runs with an FCA, SRA and CQC-aware compliance layer, and the process is designed around approval cycles rather than in spite of them. The constraint is real: copy needs sign-off, claims need substantiation, and an unsubstantiated performance claim is a regulatory exposure. Regulated engagements are priced accordingly.
