“Automated migrations copy over years of broken tags. A manual rebuild gives you data your team can actually use to make decisions.”

Core deliverables

What you walk away with.

Three concrete outcomes. Every audit. Same rhythm, ranked by dollar impact.

Outcome 1

A clean, flat event schema

We translate your legacy Category/Action/Label structures into GA4's flat, event-based tracking schema. No automated bulk-imports, no duplicate triggers, and no orphaned tags.

Outcome 2

Privacy-compliant tracking by default

We integrate Consent Mode v2 to align your tracking with GDPR, DMA, and CCPA regulations. Your tags respect user consent states without breaking your behavioral modeling.

Outcome 3

Reconciled data you can trust

We validate your GA4 conversion and transaction data against your actual backend CRM or database records, identifying and fixing discrepancies so your reports match your pipeline.

QA and data reconciliation report

Our seven-phase migration process.

We don't run automated scripts. We manually rebuild your tracking from the ground up to ensure data integrity. Here is exactly what we deliver in each phase.

1
Phase 1

Discovery & legacy audit

We review your current setup, target broken auto-migrated settings, analyze business objectives, and define which metrics are critical to keep tracking.
