MJ Marketing
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. I 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.

  1. 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.

  2. 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.

  3. 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.

01

Classification first

I 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.

02

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.

03

Server-side where it pays off

Server-side isn't for everyone. I 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 I 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

I 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. I build hand-crafted with clear logic, even though more initial effort.

FAQ

Common tracking setup questions.

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.
