I have been asked this question enough times now that it deserves a proper answer: why GEO, why now, and why Sheffield?

The short version is that I saw something that most agencies were not ready to see, and I decided to build for it rather than wait for permission. The longer version is messier, more personal, and probably more useful if you are trying to understand what MarGen is and why it exists.

The Shift I Could Not Ignore

Before MarGen became a GEO agency, I was running a growth consultancy. Helping B2B companies — mostly tech, some professional services — build their marketing engines. Content, lead generation, sales enablement. It worked well enough.

But in late 2024, something started bothering me. I was watching the AI search landscape take shape in real time — ChatGPT adding search, Perplexity gaining serious traction, Google rolling AI Overviews into more and more queries — and I could see that the foundations we were building for clients were about to become inadequate.

Not wrong. Not useless. Inadequate.

Traditional search was not dying. But a second discovery layer was forming on top of it, and this new layer worked on fundamentally different principles. It did not rank pages. It synthesised answers. It decided, in real time, which brands to name and which to leave out. And the signals it used to make those decisions were related to SEO signals but not identical to them.

I talked to agency founders I respected. Most of them said some version of: “It is too early. Wait for it to settle. Let the enterprise agencies figure it out first.”

That advice was rational. It was also wrong.

Why I Did Not Wait

The reason I did not wait is simple: I could see that the firms who moved first would build compounding advantages that latecomers could not easily displace.

AI models are not like search engines in one critical respect. Search engines re-evaluate rankings constantly. A competitor who optimises aggressively can overtake you in months. AI models, by contrast, build on their own previous outputs. A brand that is cited consistently today becomes more likely to be cited tomorrow, because the model has already established that brand as a relevant source. Citation authority compounds.

Waiting for the market to settle meant waiting while the citation landscape was being claimed by whoever moved first. For regulated sectors — financial services, legal, healthcare — this mattered even more, because these are the sectors where AI models are most cautious about which sources to cite. Getting in early, with the right signals, creates a durable advantage.

So I pivoted. MarGen became a GEO agency. Not a general digital marketing agency that added GEO as a service line. A specialist. The Synaptic Authority Engine was the methodology we built from the ground up to address this specific problem.

Why Regulated Sectors

People ask why we focus on regulated industries — financial services, legal, healthcare, construction. The answer is that these are the sectors where GEO matters most and where general agencies are least equipped to deliver it.

Regulated firms cannot take a “move fast and break things” approach to AI visibility. Everything they publish is subject to regulatory scrutiny. Financial services content must meet FCA standards. Legal content must comply with SRA rules. Healthcare content must be clinically defensible.

Most agencies treat compliance as an inconvenience — a set of restrictions that limit what they can do. We treat it as a strategic advantage. The constraints of regulated sectors force a level of rigour that actually produces better GEO outcomes, because AI models reward exactly the signals that compliance demands: accuracy, attribution, specificity, and authority.

Building a GEO agency for regulated sectors means understanding both the AI citation mechanics and the regulatory landscape. It is a harder niche to serve, which is precisely why most agencies avoid it. And precisely why the firms we work with need someone who does not.

Why Sheffield, Not London

This is the question people in London ask. People in Sheffield already know the answer.

London is where you go if your business model depends on proximity to a specific ecosystem — enterprise agencies that need to be in the same postcode as their FTSE 250 clients, or VC-funded startups that need to be near their investors. MarGen is neither of those things.

Our clients are across the UK. We work with IFA practices in the Midlands, law firms in Manchester, healthcare clinics in Edinburgh, construction companies in Leeds. The work is done remotely. The methodology is what matters, not the address on our letterhead.

Sheffield has something London does not: perspective. When you are outside the London agency bubble, you see the UK business landscape more clearly. You see the thousands of mid-market firms that are underserved by agencies that chase enterprise accounts. You see the Northern businesses that have been told — implicitly or explicitly — that serious marketing capability lives in London and they should be grateful for whatever attention trickles up the M1.

That is nonsense. And the AI search shift makes it more nonsensical than ever, because AI does not care where your agency is based. It cares whether your signals are right. A firm in Sheffield with strong entity signals, structured content, and genuine expertise will be cited ahead of a London firm that has spent more on its office lease than its GEO strategy.

I built MarGen in Sheffield because this is where I live, this is where I work, and the location has never once been a disadvantage. If anything, it is an advantage — it keeps us honest about who we serve and why.

What I Got Wrong

I want to be honest about this because the founder narrative that says “I saw the future perfectly and executed flawlessly” is always a lie.

I underestimated how long it would take for the UK market to recognise GEO as a distinct discipline. Through most of 2025, we were explaining the concept from scratch in every conversation. “You mean SEO?” No. “Is this the same as AEO?” Related, but no. “Is this just content marketing?” Absolutely not. Those conversations are shorter now, but they still happen more often than they should.

I also overestimated how quickly AI search platforms would reach mainstream UK business adoption. The consumer adoption curve was steep. The business adoption curve — particularly in regulated sectors — has been slower. Buyers in financial services and legal are cautious by nature and by regulation. That caution is appropriate, but it means the sales cycle for GEO services is longer than I initially planned for.

What I did not get wrong was the direction. The shift towards AI-mediated discovery is real, accelerating, and irreversible. The firms that build visibility now will own their categories. The firms that wait will spend more to achieve less.

Where MarGen Is Going

MarGen exists to do one thing well: make UK regulated businesses visible in AI search. Not to be all things to all clients. Not to bolt GEO onto an existing service catalogue. One discipline, done properly, for the businesses that need it most.

The Synaptic Authority Engine is the methodology. The 90-day implementation is how we deliver it. The results — documented in our case studies — are what we are measured by.

If you are a CMO or founder at a regulated UK firm, and you are starting to ask questions about how AI search affects your visibility, I would welcome the conversation. Not a sales pitch — a conversation about where the market is heading and whether your firm is positioned for it.

Get in touch. I am easy to find. I am the GEO agency founder who chose Sheffield and never looked back.
