Google Marketing Platform Measurement Consulting
Like a submarine that becomes the fleet's eyes in the deep, RED SUB Inc. measures your web and app data precisely and turns it into decisions you can trust. Centered on Google Analytics 4 and Google Tag Manager, one senior specialist owns the work end to end — from collection design through validation to reporting.
GA4 consulting & implementation
GA4 account/property design, migration from Universal Analytics, event and conversion design, multi-site and multi-region standardization. We design measurement backward from your business goals: what to measure, why, and how.
- New GA4 builds and structural redesign
- Standard e-commerce event spec (view, add-to-cart, checkout, purchase)
- Multi-site unified measurement (large-portfolio standardization)
- Event parity for GA4 + Adobe Analytics dual-stack environments
GTM tagging design & implementation
One canonical tagging architecture unifies measurement scattered across sites. Minimizing per-site branching reduces both maintenance burden and data drift.
- Standard GTM template and data-layer design
- Structured tags/triggers/variables with DebugView QA
- Repair of measurement broken by site redesigns or tag changes
Measurement planning
We document the KPI → event/parameter mapping and continuously validate data quality. Making the numbers trustworthy is the core of the work.
- Measurement plan (KPI, events, conversion mapping)
- Data-integrity checks (collection gaps, double-counting, cross-domain)
- BigQuery raw-event cross-validation to resolve UI discrepancies
BigQuery · Looker Studio reporting
We build reporting that teams use directly — so marketing and sales find answers without an analyst in the middle.
- GA4 BigQuery export setup and standard queries
- Looker Studio dashboards (funnels, conversion, per-team views)
- Scheduled reporting and anomaly detection
