How we work
A five-step process to clean, defensible data.
01
Audit
We map every event, tag and pixel against your real funnel and flag every gap.
02
Spec
A tracking plan: events, parameters, user properties, conversions — signed off before we build.
03
Build
Server-side GTM, GA4, consent mode, ad pixels — version-controlled and documented.
04
QA
DebugView, Tag Assistant, BigQuery checks. Nothing ships without proof it works.
05
Enable
Dashboards, training, and a handover doc your team can actually use.

Why ImpactBrains
Built like software.
Built like software.
Documented like infrastructure.
Tracking isn't a side-quest. It's the foundation of every paid-media, CRO, and attribution decision you'll ever make. We build it like it matters.
Engineers, not 'analysts'
We write the JavaScript, the dataLayer spec, and the Cloud Run config — not just opinions.
Privacy-first by default
Consent Mode v2, server-side, first-party cookies. Future-proofed for what's next.
Documented to handover
Tracking plan, container notes, dashboards. You own everything when we're done.
Ad platform fluent
Meta CAPI, Google Enhanced Conversions, TikTok Events API — wired correctly the first time.
FAQ
Questions, answered.
If you run paid media at scale, sell e-commerce, or operate in Europe — yes. Server-side gives you first-party data, longer cookie life, faster pages, and better attribution as browsers tighten.
A clean GA4 + GTM rebuild typically ships in 2–4 weeks. A full stack with sGTM, Consent Mode v2, BigQuery and dashboards runs 4–8 weeks depending on the funnel.
Yes. We rebuild your tracking in GA4 the right way — not a copy-paste migration. You'll usually end up with cleaner data than UA ever gave you.
Every European/UK client ships with Consent Mode v2, a CMP integration of your choice, and modelled conversions where users decline.
Yes — we deliver a documented tracking plan, container notes, naming conventions and a 60-min handover session. Most clients self-serve from day one.
Always happy to. We provide the spec, code snippets and QA — your devs ship the dataLayer or push to staging for us. Whichever is faster.
