Etalon Engineering

Marketing data engineering that stays accurate inside the rules.

Etalon Spectra shows what must stop. Etalon engineers rebuild the tracking you're allowed to keep across GTM, GA4, advertising platforms, server-side infrastructure, and reporting—so privacy enforcement does not leave your team with data it cannot trust.

Illustrative architecture only. No live environment is connected.

01 / The handoff

Spectra finds the gap. Engineering rebuilds the system around it.

Stopping a non-permitted tag is only the first step. The change can alter attribution, conversion counts, audiences, and reporting. Etalon engineers trace those dependencies, rebuild the permitted events, and validate the result across the stack.

  1. 01

    Observe

    Spectra records what fires before and after opt-out.

  2. 02

    Enforce

    Etalon Opt-Out Mode applies the supported behavior in GTM.

  3. 03

    Rebuild

    Engineering restores reliable measurement on the tracking you're allowed to keep.

  4. 04

    Validate

    QA tests the corrected behavior and documents the result.

The scanner is the evidence. Engineering is the change to the stack.

02 / One architecture

Build the measurement layer as one system.

Consent signals, event definitions, tag logic, delivery routes, platform conversions, warehouse tables, and reporting depend on one another. Etalon engineers them together.

  1. 01

    Control plane

    Privacy control plane

    Etalon does not replace your CMP. It makes the the visitor's choice operative in the tracking stack.

    • CMP and applicable privacy-signal integration
    • Consent Mode and Etalon Opt-Out Mode coexistence
    • Tag suppression, restriction, transformation, and routing rules
    • Documented fallback behavior
  2. 02

    Event contract

    Measurement foundation

    • Data-layer design and event taxonomy
    • GA4 events, parameters, and key-event mapping
    • Google Ads, Meta, and LinkedIn conversion mapping
    • Forms, calls, iframe interactions, cross-domain journeys, and ecommerce events where applicable
    • Browser/server deduplication and source reconciliation
  3. 03

    Destination governance

    Delivery and activation

    • Client-side Google Tag Manager as a complete implementation path
    • Server-side GTM, first-party endpoints, and conversion APIs when justified
    • Payload filtering, transformation, routing, and destination governance
    • BigQuery or other approved downstream delivery where it is part of the architecture
  4. 04

    Downstream outputs

    Data and reporting

    Dashboards are downstream outputs. Etalon fixes the measurement foundation before designing the view.

    • BigQuery measurement datasets and source harmonization when in scope
    • QA reconciliation between source events and destination platforms
    • Looker Studio decision views when reporting is part of the engagement
    • Documented metric definitions and ownership

03 / Conversion measurement

Every conversion needs a defined path and a testable result.

Etalon maps each business action from the interface event to the analytics and advertising platforms like Google Ads and Meta that are permitted to receive it. Then we test the handoff at every layer.

  • Debugging, browser/device QA, and destination-platform validation
  • Documentation of events, triggers, parameters, consent conditions, and owners

04 / Server-side decisions

Server-side is an extension—not a default.

Server-side GTM can centralize routing, transformations, deduplication, and platform APIs. It does not create consent, make a site compliant, or belong in every stack. Etalon recommends it only when the architecture and operating model justify it.

Architecture decisionComplete path → optional extension

Start with client-side GTM when:

  • The privacy decision can be applied before the tag sends data
  • The destination set and transformation requirements are straightforward
  • A smaller operating footprint is the better system design

Add a server-side extension when:

  • Conversion APIs or a controlled first-party endpoint are required
  • Payload filtering, transformation, or deduplication should be centralized
  • Multiple domains or platforms like Google Ads and Meta need a governed routing layer
  • The organization can own the hosting and monitoring model, or scopes Etalon to support it

The architecture decides. The trend does not.

05 / Build and migration

Change the architecture without losing the baseline.

Etalon stages changes against a documented current state, validates the new path, and hands over an architecture your team can operate.

  1. 01

    Map

    Current data flows, containers, vendors, platforms like Google Ads and Meta, dependencies, and known Spectra findings.

  2. 02

    Design

    Target architecture, event contract, privacy controls, ownership, and rollout plan.

  3. 03

    Build

    Versioned implementation across the agreed client-side, server-side, platform, and reporting layers.

  4. 04

    Validate

    Browser and device QA, platform diagnostics, reconciliation, and Spectra QA where privacy behavior is in scope.

  5. 05

    Hand off

    Architecture map, measurement specification, QA matrix, container/version notes, runbook, and change log.

  6. 06

    Operate

    Optional ongoing engineering support for future releases and incidents.

06 / Ongoing engineering

Keep measurement reliable as the stack changes.

New pages, campaign tags, CMP updates, vendor releases, and product changes can reintroduce drift. Etalon can stay involved as the engineering owner or as a review layer for your internal team.

  • Release and regression QA
  • Tracking-incident diagnosis
  • Container and event-schema change control
  • Scheduled health reviews and anomaly investigation
  • Documentation maintenance and technical handoff
  • Coordination with marketing, development, privacy, data, and agency teams

07 / Engagement model

Use Etalon as your engineering team—or an extension of yours.

Own the build

No in-house tracking specialist

Etalon owns the architecture, implementation, validation, documentation, and handoff for the agreed measurement scope.

Extend your team

Existing analytics or engineering team

Etalon supplies the target architecture, handles difficult implementation work, reviews internal changes, and validates the completed path.

Scope depends on containers, domains, tags and vendors, CMP configuration, server-side architecture, and existing technical debt.

GTM / GA4 / Google Ads / Meta / LinkedIn / BigQuery / Looker Studio / leading CMPs

Technology selection follows the agreed scope.

08 / Engineering FAQ

Engineering FAQ

What is the difference between Etalon Spectra and Etalon Engineering?

Etalon Spectra observes and reports tracking behavior. Etalon Engineering changes the implementation. Etalon Opt-Out Mode is the GTM enforcement framework used in supported environments, and QA verifies the resulting behavior.

Does an engineering engagement need to start with an Etalon Spectra scan?

For opt-out remediation, a Spectra scan is the preferred starting point because it provides an observed baseline. Broader architecture and migration work can begin with technical discovery, with Spectra used wherever privacy behavior must be validated.

Do we need server-side GTM?

No. Client-side GTM is a complete implementation path. Etalon adds server-side infrastructure only when conversion APIs, first-party endpoints, centralized transformation, deduplication, or routing requirements justify the added operating model.

Does Etalon replace our CMP or cookie banner?

No. Your CMP records the visitor’s choice. Etalon integrates that signal with the tracking stack, applies supported enforcement behavior, and verifies what happens next.

Can Google Consent Mode and Etalon Opt-Out Mode coexist?

Yes. They have related but different responsibilities. Etalon maps the signals and tag behavior to the supported architecture, then tests the combined configuration.

Can Etalon work with our internal team or agency?

Yes. Etalon can own the full engineering scope or take responsibility for architecture, difficult implementation work, review, QA, and documentation alongside an existing team.

Does Etalon build Looker Studio dashboards?

When reporting is part of the agreed scope, Etalon can build decision views in Looker Studio. The source measurement and metric definitions are stabilized first.

Does Etalon manage advertising campaigns?

No. Etalon engineers the measurement infrastructure that analytics and advertising platforms depend on. Campaign strategy and media management remain with the customer or its agency.

What determines the scope of an engineering engagement?

Scope depends on containers, domains, tags and vendors, CMP configuration, server-side architecture, reporting requirements, and existing technical debt.
