Website Tracking · Main Service

Clean tracking architecture across all platforms — Google Ads, Meta, LinkedIn, TikTok. Server-side when it counts.

Standard tracking loses 25-45% of your conversions in practice: through iOS-14, cookie consent refusals, cross-device gaps. We build platform-agnostic architecture that delivers clean data back to all ad systems — Smart Bidding, Performance Max, lookalikes all work again with real signals.

Three typical mandates

From audit to server-side architecture.

Format 1
Tracking audit
Inventory: which platforms track already, where data is lost, which conversions are double-counted. Output: 8-area audit report with prioritised fixes. €700 fixed price, 5 working days.
Format 2
Multi-platform setup
Full build across all relevant platforms: GTM, GA4, Google Ads Enhanced Conversions, Meta Conversions API, LinkedIn Insight Tag, TikTok Pixel + Events API. Including Consent Mode v2 + handover docs. 3-4 weeks delivery.
Format 3
Server-side architecture
When browser tracking isn't enough: server-side container (Cloud Run), iOS-14 loss recovery, cross-device identifier stitching, first-party data pipelines. 4-6 weeks, for e-com + complex funnels.

Three principles

Platform-agnostic, cleanly documented.

Classification first

We map every tag, cookie, third-party script before configuring. Only then do we talk banner copy or server-side. 80% of bad tracking setups skip this step.

Custom over templates

Hand-built GTM architecture with consistent naming convention. No auto-track templates that look like much but deliver data garbage. Your team can maintain it later — that's the explicit goal.

Server-side where it pays off

Server-side isn't for everyone. We build it for e-com, long conversion paths, apps with iOS share >40%, multi-domain setups. For simple lead-gen sites, custom GTM browser-side often suffices.

Pricing

Three tiers — audit, setup, architecture.

Fixed price per mandate. Payment before project start. Handover documentation always included.

Tracking audit

€700

One-off, 5 working days. Recommended for existing setups suspected of data loss

8-area audit report
Platform coverage check
Prioritised fix list
30-min walkthrough call

Multi-platform setup

€2,500

Project, 3-4 weeks. Recommended for fresh build across 2-4 ad platforms

GTM + GA4 + 3-4 ad platforms
Consent Mode v2 clean
Enhanced Conversions / CAPI
Handover doc + 60-min walkthrough

Server-side architecture

€4,000

Project, 4-6 weeks. Recommended for e-com, iOS recovery, cross-device, multi-domain

Server-side container (Cloud Run)
Cross-device identifier stitching
First-party data pipelines
Handover doc + 90-min walkthrough

What's not included

External hosting costs (Cloud Run: typically €15-40/mo) are not in the fixed price. Ongoing maintenance optional as retainer from €300/month — or your team takes over with the handover doc.

Project

Fixed price with clear scope.

Delivery time

Audit 5 days · Setup 3-4 wks · Server-side 4-6 wks.

Payment

In full before project start.

What you don't get

Anti-bullshit guarantee.

What's standard in the tracking market — and we explicitly don't do:

No "100% iOS recovery" promise

Anyone promising that is lying or ignoring Apple's privacy limits. Realistic is 25-40% recovery via server-side; more isn't honest.

No vendor lock-in

We recommend GTM (free) + custom setup, not Tealium / Adobe Launch / Segment. If you switch later, the architecture is portable.

No "GA4 is enough"

GA4 is a reporting tool, not a conversion-tracking layer. Anyone selling GA4 as a complete tracking solution hasn't understood it.

No auto-track-mode voodoo

GTM's auto-track templates fill the account with meaningless events. We build hand-crafted with clear logic — even though more initial effort.

FAQ

Common tracking setup questions.

If you only run Google Ads and nothing else — that's often enough. But once you add Meta, LinkedIn, or TikTok, you have 3 parallel tracking systems that don't talk to each other. A centralised custom GTM container fixes that.

The sub-service is Google-Ads-specific (GTM + Consent Mode v2 for the Google platform). This main service is platform-agnostic — we build tracking architecture serving GA4 + Google + Meta + LinkedIn + TikTok. Larger scope, higher price.

Not everyone. Server-side pays off for: e-com with long conversion paths, iOS share over 40%, multi-domain setups, or when privacy/compliance is central. For simple lead-gen sites, custom GTM browser-side usually suffices.

Cloud Run or similar: typically €15-40/month at moderate traffic. At high traffic also €50-100. You pay directly to Google Cloud / AWS, not us. We help with setup and cost monitoring.

Yes, that's explicitly the goal. Handover doc includes tag map, naming convention, maintenance guide, what shouldn't be touched. Most routine adjustments are doable by someone with GTM basics in 30 min.

Keep it. We integrate the existing CMP into the new tracking stack. If you want to switch, we do the migration as add-on (€500-€1,500 by complexity).

Discovery call

30 minutes — we scope the setup.

You explain platform stack, conversion paths, current data-loss suspicions. I say which tier fits (audit / setup / server-side) and deliver a fixed-price offer within 48h after receiving all necessary info. If your current setup is fine, I'll tell you that too.
