Three answers to one question.

How many conversions did last month have? In tracking that grew market by market, every system tells a different story, and meetings become debates about whose number is right.

Before

GA41,412

Ad platforms2,904

Warehouse1,987

Same shop, same month, three totals. Nobody can say which one is real.

After one measurement layer

1,412

The number everyone steers by

GA4 properties3 → 1

Definitions of a lead4 → 1

Tag routes10 → one spec

Markets4, one taxonomy

From one multi-market rebuild: one definition of a conversion, enforced from dataLayer to warehouse.

Why reliable tracking is a performance lever, not a checkbox

What we do.

Audit first, then build, then keep it running.

Tracking audit

A structured review of tags, pixels, consent and conversion flows.

You get: findings report · prioritized fix list · quick wins for week one

Rebuild

DataLayer, GA4, server-side tagging and pixels, built to match your business definitions.

You get: event taxonomy · dataLayer spec · GTM and server-side setup, QA’d across consent states

Consent & governance

CMP, Consent Mode and firing rules, aligned with legal and documented.

You get: CMP configuration · Consent Mode setup · firing-rule documentation legal can sign off

Data engineering

BigQuery pipelines and Dataform models that turn clean events into reporting-ready tables.

You get: modeled reporting tables · scheduled assertions · one source of truth for dashboards and finance

Operations

Release QA, monitoring and monthly data quality checks, so tracking stops breaking quietly.

You get: monitoring and alerting · release QA protocol · monthly data quality report

How we work.

Discovery

We map your stack, goals and known trust issues.

Architecture

Events, destinations, consent rules and source-of-truth decisions, agreed before the build.

Implementation

GTM, GA4, server-side and pixels, tested across browsers and consent states.

Operations

Monitoring and release QA keep the foundation stable while everything around it changes.

Every change ships with a spec.

Events, parameters, consent conditions, destinations and ownership, written down before anything goes live. Documentation is the deliverable, not an afterthought.

They will never match, and none of them is lying. What each number counts, and which one to use for what.

Let’s look at your setup.

A short call about your stack, where trust breaks today, and whether a structured audit makes sense.
