Paid Media
Growth you can attribute. Full-funnel buying on Meta, Google and TikTok, optimised to incremental revenue — not the last-click credit platforms award themselves.
Performance marketing + GMD 360 · Shopify · EU & UK
Your ROAS looks great — that's exactly the problem
Most Shopify brands scale on ROAS: the most flattering, most misleading number in the account. GM Digital runs your paid media against store truth — blended MER and what it really costs to win a new customer — and gives you GMD 360, our AI-powered reporting platform, built on store truth.

What we do
The best of agency and in-house — small by design.
Four disciplines, one feedback loop. The people you meet are the people on your account — we sit inside your business, not beside it, and decide against store truth, not platform-reported fiction.
Attribution & Measurement
Our own warehouse — BigQuery + dbt — with multi-touch, Markov and marketing-mix models that reconcile platform claims against store truth.
Creative Analytics
Know which three seconds sell — and which ad to cut before it drains spend. Hook-rate, hold and CTR by creative.
UX & CRO Audits
Turn checkout and PDP friction into found revenue. Baymard-grounded audits, prioritised by impact, not opinion.
Why we don't optimise to ROAS
The number you trust most is the one lying to you
ROAS counts platform-claimed revenue and ignores whether a sale was new or repeat, cheap or expensive to win — so you can grow revenue while your profit shrinks. Meta and Google both claim the same order; GA4 misses the paid orders it can't see.
Here's a better approach: we reconcile every platform against Shopify and optimise to two numbers instead — MER (total revenue ÷ total ad spend, the blended truth) and new-customer CAC (what it actually costs to win a customer who wasn't coming back anyway). Almost no one reports these. We start here.
Same 28 days · one brandIllustrative
Each platform takes full credit, so the numbers don't add up. The real figure is the one that reconciles to Shopify.
The visibility gapPartial confidence
GA4 typically tracks ~60–80% of store revenue. The missing slice is disproportionately paid-driven — exactly the orders you're trying to attribute.
Store truthHigh confidence
Once platforms are reconciled to Shopify, ROAS and revenue agree within ~10% — and budget moves are defensible to the board.
How we work
Measure first. Then scale
We call it the Store-Truth Loop: measurement first, then media, so every euro of scale is a decision, not a guess. Four steps that compound month over month.

About
Small by design.
GM Digital is a small, senior team with 11 years across agency and in-house — we've sat on both sides of the table, so we run your accounts the way we'd want ours run.
You work directly with the people doing the work — no account managers relaying messages, no seniority theater where you're sold senior expertise and handed a junior. We stay small on purpose, take on few brands, and go deep — which is why clients stay with us for two to five years, not one campaign.

FAQ
The questions we get first.
We already have an agency or in-house team — why you?
We don't replace your team unless you want us to — we install the measurement layer most setups are missing, then run or advise the media on top. Often we're the first to tell you which of your channels is actually incremental.
How do I know your "store truth" numbers are right?
They reconcile to Shopify — the same figure your bank sees. Every platform claim is lined up against store revenue in the warehouse, agreeing within ~10%. If it doesn't reconcile, we don't report it.
Can you help with our Shopify store or automations too?
Yes. Through vetted partners we handle Shopify builds, migrations and support, plus AI automation of manual processes — with us as your single point of contact.
Do you need access to our data warehouse?
We build one for you — BigQuery + dbt — or work inside yours. Either way, you own the warehouse and the models; nothing is locked to us.
Is there a minimum ad budget?
We work best with established brands already investing meaningfully in paid media, where proper measurement starts to pay for itself. Not sure whether you're a fit? Just ask — we'll tell you straight.
How do you charge?
A monthly retainer scoped to your spend and the measurement stack we run — no percentage-of-spend incentive to inflate budgets, and no long lock-ins.
Which platforms do you run?
Meta, Google and TikTok for media, full-funnel. For measurement we connect GA4, Search Console and Shopify, and reconcile everything in the warehouse.
What does onboarding look like?
Diagnosis and warehouse setup in the first two to three weeks, then scaling from week four. We measure before we spend.
