Collection & implementation


GA4 Audit & Remediation Planning
Start here when the property was inherited and nobody can say yet whether it is trustworthy; every finding arrives ranked and backed by an export.


GA4 Implementation & Configuration
There is nothing to audit yet. Streams, retention, internal-traffic filters, and how markets roll up all need settling before the first event is named.


GA4 Event & Conversion Tracking
The property settings hold up, but one business action reaches GA4 under several event names, so no report can say which of them counts as the conversion.


GA4 Ecommerce & dataLayer Implementation
Choose this when GA4 revenue and the order system disagree for commerce reasons — item arrays, refunds, coupons, or a multi-currency cart nobody has reconciled.


GA4 Integrations & Data Activation
The property is trusted and the open question now points outward, to which Ads link, BigQuery export, or audience destination stays on and who answers for it.


GA4 Reporting Validation & Reconciliation
One GA4 figure is disputed against a CRM or finance total, and the argument needs a verdict on that single report rather than another property-wide sweep.
When this owner applies
GA4 needs a shared contract before it needs more reports
This service configures and validates GA4 properties, business events, ecommerce collection, integrations, and reporting so teams can work from an agreed contract.
Capability boundary
GA4 owns meaning while GTM owns deployment
GA4 owns the property contract. GTM owns browser-side tag deployment.
Evidence-led delivery
Contracts before tools, acceptance before claims
Every engagement has named inputs, owners, human approval gates, reproducible QA, explicit limitations, and an operating handover.
We configure and validate GA4 streams, custom dimensions, key events, and ecommerce models against agreed specifications. Zeo specialists run DebugView journey tests and BigQuery reconciliation, while your team authorizes property access and accepts final reporting accuracy.


The Google Analytics & GA4 delivery lifecycle
Audit property & events
We inspect current GA4 data streams, custom definitions, key events, referral exclusion lists, and Google Signals settings to identify configuration drift.
Configure schema & dataLayers
We structure GA4 property settings, event schemas, custom parameters, and ecommerce dataLayer pushes according to your business requirements.
Validate in DebugView
We test representative user journeys in DebugView, validating parameter formatting, deduplication keys, and event trigger timing.
Activate & reconcile
We establish BigQuery export links, connect Google Ads audiences, and deliver automated reconciliation reports comparing GA4 against backend order logs.

Tools we use
The measurement stack behind the work
Collection, tagging, product analytics and reporting are separate problems with separate tools. These are the ones we build measurement on.
Core web analytics platforms
- Google AnalyticsAcross audit, configuration, event tracking, and reporting validation, GA4 is the property we govern directly rather than a downstream report we build from. That distinction is what separates a GA4 consulting engagement from an analytics-owner page that treats GA4 purely as a data source: here the property's own settings, retention rules, and event contract are the deliverable.
- Adobe AnalyticsFor a client running Adobe Analytics alongside GA4, whether mid-migration or by design, we reconcile the two platforms' definitions and numbers as part of the audit, since a metric that means one thing in Adobe's processing rules can mean something subtly different once it lands in GA4. That reconciliation is scoped to the migration or dual-run case specifically, not a default part of every engagement.
- MatomoWhen a client's privacy or data-residency requirements make a fully self-hosted or EU-hosted platform necessary alongside or instead of GA4, we configure Matomo to run in parallel with the same event contract wherever possible. That parallel-run approach is what lets a client test a migration path without losing GA4's historical baseline mid-project.
Tag management, CDPs & server-side tracking
- Google Tag ManagerWe treat GTM's container version history as a separate evidence source from the GA4 property itself, since deployment and configuration are two different systems that can each break independently. Cross-referencing GTM's publish dates against when GA4's numbers actually shift is how a finding gets dated to a specific change instead of described as broken now.
BI, dashboards & reporting
- Looker StudioFindings from a GA4 audit get ranked by decision impact and delivered as a Looker Studio readout the client's team keeps open and works through. That format is the actual deliverable of an audit-and-planning engagement, distinct from the ongoing operational dashboards a data-visualization page would build.
- SupermetricsDuring the integrations and activation step, when a report needs GA4 sitting next to ad platforms or other marketing tools GA4 does not natively connect to, we route the blend through Supermetrics. That blended feed is what lets a stakeholder see GA4 conversions next to ad spend without a manual export-and-merge step.
Product & mobile app analytics
- Firebase AnalyticsWhen a client's property spans a native mobile app, we configure Firebase Analytics as the same underlying event schema GA4 uses for web, since Firebase Analytics is GA4's own mobile SDK rather than a competing platform. That shared model is what keeps a cross-platform property's events consistent between the app and the site.
- MixpanelWhen a client's product team already runs Mixpanel independently of the marketing-facing GA4 property, we review how the two event definitions relate during the integrations and activation step, since the same user action can be named differently in each system. That reconciliation keeps a cross-functional KPI from meaning two different things depending on who pulled the number.
- AmplitudeWhere a client's product team already standardizes on Amplitude rather than Mixpanel, we reconcile the same event-definition gap against it during integrations work. Which of the two we check against follows the client's existing tool, not a fixed preference in this GA4 consulting practice.
Session replay, heatmaps & experience analytics
- ContentsquareWhen the GA4 audit surfaces an anomaly a quantitative report cannot fully explain, a sudden drop in a specific event's rate, we cross-check it against Hotjar recordings for the same period. Seeing the actual session is sometimes the fastest way to confirm whether the finding is a tracking break or a real behavior change.
- Microsoft ClarityFor a client where a paid session-replay tool is not justified, or one already standardized on Microsoft's ecosystem, we run the same anomaly cross-check through Microsoft Clarity instead of Hotjar. It answers the identical question, whether a GA4 finding reflects a real behavior change, at no added licensing cost.
Privacy-first & cookieless analytics
- Piwik PROFor a client with compliance requirements beyond what a self-hosted Matomo instance satisfies, HIPAA-eligible hosting or a managed compliance posture, we configure Piwik PRO instead. It sits alongside Matomo in this consulting practice as the more enterprise-managed option for the same underlying need, a GA4 alternative or parallel that satisfies stricter data rules.
