A 13-person agency running SEO, GEO, PPC and affiliate for UK ecommerce brands.

We've been doing this from Durham since 2014. No offices in three cities, no account management layer, no sales floor. Thirteen specialists, four service lines, and clients who tend to stay for years rather than months.

This page exists so you can check we're what we say we are. Everything below is verifiable — the brands, the credentials, and the people who'd actually work on your account.

What we do

Four service lines. Specialists in each.

Our SEO team only does SEO. Our PPC team only does PPC. Nobody here splits their week across three disciplines and calls themselves a digital marketer.

SEO

Organic search

Technical, content and digital PR run as one programme. Migrations, category architecture, and the unglamorous fixes that actually move rankings.

Our SEO service →
GEO

AI search visibility

Getting your brand cited in ChatGPT, Google AI Overviews and Perplexity — measured with prompt tracking and AI referral data, not guesswork.

Talk to us about GEO →
PPC

Paid search

Google and Microsoft Ads built around ROAS and contribution margin. Feed management, Performance Max, and conversion tracking that reconciles to finance.

Our PPC service →
Affiliate

Affiliate marketing

Programme management across the major networks, with a bias towards incremental partners over cashback padding. Partnerize Diamond accredited.

The number that matters

Our clients stay an average of four years.

Retention is the honest measure of whether the work is any good. Anyone can win a client. Keeping them for a decade is harder, and it's the thing we'd check if we were you.

SEO & PPC across multiple sites

We've worked with Glass Digital for a few years now and they handle our SEO campaign, as well as the PPC side of things for a number of our websites. The teams there are very knowledgeable and we're always happy with the work they produce for us.

Magento 1 → Magento 2 migration

Internally we had a lot of pressure to maintain our organic rankings, particularly on high traffic hero terms, during the migration. Our new site not only maintained these rankings, but we have seen sustained improvements since launch.

What's actually different

Four things about how we're built.

Not values — values are free to claim. These are structural decisions about how the business runs, and each one has a cost attached that most agencies aren't willing to pay.

How performance is measured

Our teams are measured on your results, not on your retainer.

At most agencies, an account team is judged on revenue retained — which rewards holding onto clients rather than growing them. Ours are measured against the campaign targets we agree with you: ROAS, revenue, positions. The people running your account have something riding on whether those numbers move.

What you get before you pay

An audit that tells you what's wrong, whether you hire us or not.

Most agency "audits" are pitch decks in disguise. Ours aren't. Specific issues with your current campaign, the reasoning behind each one, what we'd change, and where you sit against competitors. Most prospects keep it either way.

Who does the work

The person on your call is the person on your account.

Thirteen people means no account management layer passing messages along, and no gap between the senior people who pitch and the juniors who deliver. You speak directly to the specialists running your campaign.

Where your fee goes

You pay for the work, not the overhead.

No premium city-centre offices, no large leadership team, no expensive sales operation. We run lean on purpose, which is why our retainers typically sit 20–30% below the agency average for comparable scope — with the same tooling and the same seniority.

Being straight with you

We're not the right agency for everyone.

We'd rather tell you now than three months into a contract that isn't working for either of us. If you recognise yourself below, we'll say so on the call.

If marketing spend is discretionary

We have a minimum monthly investment, and we ask for enough time to do the work properly. If committing to that would put real strain on the business, a good freelancer or an in-house hire will serve you better than we will — and we'll point you that way rather than take the work.

If you need results this month

Paid search can move quickly. SEO, GEO and affiliate compound over quarters, not weeks. If the plan depends on a step change before Christmas, we'd only be setting you up to be disappointed.

If you need everything under one roof

We do SEO, GEO, PPC and affiliate properly. We don't do social, creative, email or web build, and we won't pretend otherwise to keep a pitch alive. We'll happily work alongside whoever does.

Organic, GEO and affiliate programmes take time to prove themselves, so we'd rather agree a realistic runway up front than sell you a quarter of a programme and hope. What that looks like commercially is set out plainly further down.

Who we are

The four directors.

All four are hands-on. None of them is a figurehead you'll meet once at the pitch and never speak to again.

Credentials

Accreditations we hold now.

Current, verifiable, and earned on performance rather than paid for.

Awards

Between 2021 and 2022 we were shortlisted 44 times across the UK Search Awards, UK Biddable Media Awards, Northern Digital Awards, UK Digital Growth Awards and Prolific North. We haven't entered since — the entry fees were better spent on client work, and we'd rather you judged us on the retention figure above than on a badge from 2021.

A realistic time commitment, agreed up front. Organic, GEO and affiliate programmes need time to compound, and month-to-month working encourages the wrong kind of activity — quick wins that flatter a report. We'll be straight with you about how long the work you're asking for actually takes, and we'd rather agree that at the start than discover it halfway through.

Pricing that matches the channel. Some campaigns work best on a monthly retainer against a defined scope; on others we're paid as a percentage of the revenue we generate, so our fee moves with your results. We'll tell you which model we think fits and why. Either way it's agreed before we start — no hourly billing, no surprise invoices, no escalators buried in the terms.

Your accounts stay yours. Ad accounts, analytics properties, tracking, content and links are set up in your name from day one, and they go with you if you leave. You're never locked in by an account you can't access.

Book a free audit and we'll tell you specifically what's underperforming, why, and what we'd do differently — whether you hire us or not.
