The person behind the reports

THE BACKSTORY
How you get good at this
Experience that actually means something tends to be earned in situations where you couldn't afford to get it wrong.
My career in marketing didn't follow a conventional path. I didn't graduate into an agency, manage other people's budgets from a safe distance, or learn this trade in a room full of colleagues to blame when things went wrong. I learned it under real pressure, with real consequences, doing it myself. I'm in my early thirties, based in Essex, and what I know about marketing I know because I had no choice but to figure it out properly.
The first chapter was e-commerce. A hands-free electric toothbrush - a genuinely novel product with no existing market to tap into. Nobody was searching for it. Nobody knew they wanted it. The only path was paid social, the only tool was Facebook Ads, and the only option was to figure out how to build demand from nothing, with my own money as capital. Three months later, the account was spending £30,000 a month at a blended 3.8× ROAS. Unfortunately the profits were hard to get excited with, so I axed the project. That experience taught me more about the mechanics of scaling than any course, any agency, any textbook.
"If you can help other people make money, you will always be looked after. That's not a philosophy I read somewhere. It's something I worked out by doing it."

The second chapter was longer, slower, and in some ways more instructive.
Five years as marketing director for a family accountancy firm - with no budget, no team, and no option but to make SEO work. Most people would have given up inside a year. I found it fascinating. The puzzle of organic search. The patience it required. The compounding that eventually arrived. By the time the firm finally approved a £500/month ad budget, the SEO foundation was so solid that Google Ads hit 4× ROAS in the first month.
AdVantage UK exists because of what came next. The head accountant announced her retirement, the firm's future became uncertain, and for the first time in years I had to think seriously about what came next for me too. I'd always had an itch to go solo - to see how far I could get on my own skills and my own time. That uncertainty turned out to be the push I needed to stop thinking about it and actually do it.
The answer is this: a monthly audit service that gives small business owners the clarity they have never had about their marketing. Clear, honest, delivered fast, explained in plain English, with no meetings required. Built for busy owners who are excellent at their business but don't have the expertise - or the time - to properly fault-find their ads and SEO. That's exactly where I come in.
How i think about this
Three things I believe that most marketers don't say out loud
01
Honesty is more valuable than comfort
Most marketing reports are written to justify the person who wrote them. Mine aren't. If your campaigns are wasting money, you'll see exactly where and how much. If your SEO isn't working, I'll tell you why. Comfortable half-truths don't help anyone grow.
02
Paid and organic aren't separate strategies
The most expensive mistakes I see are caused by treating ads and SEO as siloed budgets with siloed results. Weak pages hurt quality scores. Keyword cannibalisation wastes both at once. The interactions between channels are where the most valuable insights live.
03
If you help people make money, you'll always have work
This isn't a motto I read somewhere. It's something I worked out through experience. Clients who see results don't leave. The best way to build a sustainable business is to make the service so undeniably useful that stopping feels like a bad decision.
how i work
📧
Everything is async
No discovery calls. No monthly check-ins. No Zoom catch-ups where we agree things are going well. I'm deeply introverted by nature - meetings drain me and I do my best thinking alone. As it happens, this suits busy business owners perfectly. Your report and Loom land in your inbox. Questions go to email. That's the whole relationship.
📐
Depth over volume
I work with a deliberately limited number of clients. Not because I can't handle more, but because depth of analysis is the whole product. A report that's been properly thought through is worth ten times a template with your name on it. I'd rather have fewer clients who trust me completely than more who feel like a number.
Built around how I'm wired.
Which happens to suit busy business owners perfectly.
🔍
One person looks at your account
There's no account manager briefing a junior analyst who then briefs someone else who creates a dashboard. I look at your data. I write your report. I record your Loom. That's why the output reads like it was written by someone who actually understands your business - because it was.
🎯
Straight talk, always
I don't write reports to impress you with how much data I can process. I write them to give you a genuinely useful perspective on what's happening in your marketing - the kind of view you'd have if you had 10 years of experience and eight hours to spend on your own account. That means sometimes the report contains things you'd rather not hear. That's when it's most valuable.
The person, not just the cv
What I'm like when I'm not staring at Google Ads data
I'm a deeply private person. I don't post much. I don't network for the sake of it. I'm not at industry events or on panels. If I'm not working, I'm walking somewhere quiet in nature with my fiancée, or deep in whatever rabbit hole has captured my attention that week - I've always been the kind of person who reads everything there is to read about something before moving on to the next thing.
I mention this because it actually matters for how I work.
The no-meetings, async-first model isn't a business decision, it's just who I am.
I do my best thinking alone, without interruption, with data in front of me and time to actually think about what it means. That's when the most useful insights come. The reports reflect that.
I also think there's something to be said for working with someone who has a genuine curiosity about how things work - not just marketing, but everything. The ability to look at a set of numbers and ask "why is this happening, and what does it actually mean for this specific business" is less a technical skill and more a disposition. I've always had it. It just happens to be very useful in this particular line of work.

I read obsessively about whatever has caught my attention. Currently it's AI and how it changes the economics of small business marketing.

Private by nature, but family is the anchor. Building AdVantage UK is as much about what I'm building toward as it is about the work itself.
