Numbers you can trust.
Decisions you can defend.

A measurement program built on evidence, not faith — GA4 event design, server-side tagging, consent mode, and attribution modelling, so every channel gets the credit it actually earned and no budget moves on a guess.

02 — Outcomes

Measurement that pays back.

The moves we make on this work, and what each one is there to shift. Every engagement starts by deciding which of these actually applies to you.

Server-Side Tagging
B2B SaaS · Server-side GA4
We move tagging server-side, dedupe conversions, and kill the broad campaigns the old model is over-crediting.
CutsWasted ad spend
Data-Driven Attribution
Healthcare · Attribution
We switch from last-click to data-driven, surface the upper-funnel content that is quietly driving bookings.
ImprovesROAS visibility
Governed Data Source
Industrial · Warehouse
We stream GA4 to BigQuery, model in dbt, and retire 11 stale spreadsheets for one governed source of truth.
ConsolidatesDashboards, not 40
Consent Mode Modelling
SaaS · Consent mode
We implement Consent Mode v2 with modelling, recover modeled conversions (est.) for sessions lost to cookie rejection without breaking privacy.
RestoresModeled conversions recovered (est.)
Marketing Mix Modeling
DTC · Marketing mix
We build a lightweight MMM to cross-check platform-reported ROAS and reallocate budget off double-counted channels.
OptimizesBudget efficiency
Measurement Plan Rewrite
SaaS · Event design
We rewrite the measurement plan from scratch, naming events, typing parameters, and creating a tracking spec engineering can ship.

03 — The model, live

The model decides
where the budget goes.

The same 1,000 conversions, credited four different ways. Last-click hands everything to the final touch and starves the channels that started the journey; data-driven spreads credit by modelled contribution. Switch the model and watch the budget case rewrite itself.

Attribution model
Direct
Total credited conversions 1,000
Last-click gives 100% of each conversion to the final touch — clean, but it hides every channel that opened the door.
04 — The measurement plan

Designed like a schema,
not an afterthought.

Good analytics is engineering, not a tag you paste in. Named events, typed parameters, server-side collection, consent at the edge, and a warehouse the whole team can query. This is the room we work in every day.

05 — The measurement program

Audit the data.

Before we trust a single number, we trace it. What's firing, what's double-counting, what's been broken since the last redeploy, and which decisions are quietly being made on numbers that are wrong?

BrokenPurchase event fires twice on the thank-you page
Blind34% of sessions dropped to cookie rejection, unmodelled
Over-creditLast-click hands 100% to brand search — already won
Drift11 dashboards, three definitions of "active user"

Design the plan.

A measurement plan engineering can actually ship — named events, typed parameters, the conversions that matter flagged, consent handled at the edge, and a clear path from click to warehouse row.

CollectionGA4 + GTM Server-side container
ConsentConsent Mode v2 · modelled conversions
AttributionData-driven · 90-day lookback window
WarehouseBigQuery export · dbt models nightly

Instrument cleanly.

Tags live in a server-side container, events validated against the spec, PII stripped before it leaves the edge. We test every conversion end-to-end before anyone reports on it — no number ships untested.

Server-side GTM container live · domain verified

BigQuery export armed once events stabilise

Model the truth.

Raw events become governed tables — sessions stitched, channels grouped, attribution applied in dbt where the logic is versioned and testable. One definition of every metric, reviewed like code.

/ Weeks 03–06 · Model

Decide with confidence.

Now the numbers earn their keep. Attribution exposes where budget is wasted, dashboards answer the questions the team actually asks, and every reallocation has a defensible case behind it.

Report in plain English.

A weekly read the whole team understands — what moved, what it cost, what the data says to do next. No 40-tab dashboard nobody opens; the three numbers that decide whether the spend is working.

06 — Why it compounds

Clean data compounds.

Every cycle feeds the next: cleaner events train sharper attribution, sharper attribution exposes waste, recovered budget funds the channels that actually work. Untended, tracking rots silently. Maintained, the decisions get measurably better.

The platforms we actually log into every week to collect, model, attribute, and visualise. No mystery tooling — just the kit that keeps the numbers honest.
