Event Tracking & Marketing Pixel Implementation

One event, seven platforms, seven different ways to mess it up. We implement event tracking and marketing pixels that send consistent, reliable data across every platform your marketing team depends on.

The Problem With "Just Add the Pixel"

Marketing asks for a Facebook Pixel. A developer drops the base code on the site. Events get added ad hoc sometimes in the TMS, sometimes hardcoded, sometimes through a platform integration that nobody documented. Six months later, conversion numbers don't match between GA4, Meta, and Google Ads, and nobody knows why.

The issue isn't any single pixel it's that each platform has its own event schema, its own parameter naming, its own quirks. Meta wants 'AddToCart' with a content_type parameter. GA4 wants 'add_to_cart' with an items array. Google Ads wants a conversion action with a different value format. TikTok wants its own event name entirely.

We implement all of them in a unified architecture. Same user action, same data, different endpoints configured correctly for each platform's requirements. Everything goes through your tag management system, everything is documented, everything is tested.

This is the unsexy work that makes your marketing attribution actually reliable. No attribution model can save you if the underlying event data is inconsistent.

How We Implement

Event Specification Review

We start from your event tracking plan (or help you create one). Every event is documented with its name, trigger condition, and required parameters for each destination platform. No ambiguity, no missing edge cases.

Data Layer Configuration

If your site doesn't have a data layer, we design one. If it does, we extend it. The data layer is the single source of truth all platforms read from it, ensuring data consistency. We work with your developers to implement pushes at the right moments.

TMS Tag Configuration

Tags, triggers, and variables are built in your tag management system (GTM, Tealium, Adobe Launch, or others). Each platform gets its tag configured to the platform's specifications correct event names, parameter mapping, and consent integration.

Server-Side API Integration (When Applicable)

For Meta Conversions API, Google Ads Enhanced Conversions, TikTok Events API we configure server-side event delivery alongside browser-side pixels. This improves match rates and provides resilience against ad blockers.

End-to-End Testing

Every event is tested across every platform using GTM Preview, Meta Events Manager, Google Tag Assistant, and platform-specific debugging tools. We verify parameters, values, and deduplication between client-side and server-side events.

Documentation & Handover

Complete documentation of every tag, trigger, variable, and data layer push. Your team can add new events or modify existing ones without guesswork.

What Sets This Apart

Unified architecture. All events originate from a single data layer push. Each platform reads from the same source no drift between platforms over time.

Server-side included. We configure Meta CAPI, Enhanced Conversions, and TikTok Events API alongside browser pixels. This isn't an upsell it's how modern tracking should be done.

Consent-integrated. Every pixel respects consent state. No tag fires without the appropriate consent category. This is built into the trigger logic, not bolted on afterwards.

Deduplication handled. When running both client-side pixels and server-side APIs, deduplication is critical. We configure event_id matching so platforms don't double-count conversions.

Platform-agnostic TMS. We work in GTM, Tealium, Adobe Launch, or whichever tag management system you use. The implementation methodology stays consistent.

Post-launch validation. After deployment, AssertionHub can continuously validate that all events fire correctly across all platforms.

Frequently Asked Questions

How many platforms can you implement at once?

No limit. We commonly implement GA4, Meta Pixel + CAPI, Google Ads + Enhanced Conversions, TikTok, LinkedIn, Pinterest, and Snapchat in a single engagement. Each additional platform adds 1-3 hours depending on complexity.

Do we need a data layer?

For reliable cross-platform tracking, yes. If you don't have one, we design and document it as part of the implementation. Your developers push data to the data layer; we consume it in the TMS.

What about e-commerce events?

E-commerce tracking (product views, add to cart, checkout, purchase) is our most common implementation. Each platform has its own e-commerce event schema we map them all from a single data layer structure.

Can you implement just one platform?

Absolutely. Need just a Meta Pixel with CAPI? Just GA4 enhanced e-commerce? We scope to what you need. The per-event pricing starts at 1-2 hours for standard events on a single platform.
