Conversion tracking your ad spend can trust.

I set up and repair Consent Mode V2, Google Tag Manager, GA4 and Google Ads conversion tracking for agencies and businesses, so every conversion is counted once, with consent, and where your bidding can use it.

From consent to conversions, end to end

Sound familiar

Most tracking doesn't fail loudly. It drifts, and Google Ads keeps bidding on whatever it is told.

Packages

Tracking Audit

From €150 · Fixed price · Around 3–5 days

For tracking that is already in place but can't be trusted. I follow the data from the browser to Google Ads and fix each break where it starts.

  • Review of the GTM container: what fires, what is duplicated, unused or broken
  • Every step from GTM to GA4 to Google Ads checked until it shows a healthy status
  • Bot and internal traffic filtered out of GA4
  • A written report of what was found, what was fixed and what to watch

Consent & Conversion Setup

From €350 · Fixed price · From 2 days

For sites that need to stay compliant without flying blind. The full chain, from consent banner to the conversions Google Ads optimizes on.

  • Your consent banner or CMP connected to GTM, with Consent Mode V2 and all four signals
  • A GA4 tracking plan: events, parameters and key events named deliberately
  • Google Ads primary and secondary conversions, with no double counting
  • Every consent state tested, and documentation your data protection officer can review

Ongoing Tracking Care

From €120 a month · Monthly retainer

For teams whose sites and campaigns keep changing. Tracking stays correct after the launch, not just on the day it ships.

  • A monthly check of tags, conversion actions and consent behaviour
  • Changes when the site, forms or campaigns change
  • New events and conversions added to the same standard
  • A short monthly note of what was checked and changed

Why me

You work directly with the engineer doing the work. No account managers, no hand-offs to juniors.

Tracking is my day job: I currently work in-house on tracking infrastructure for a marketing agency in Hamburg, and I've built and maintained more than 75 websites since 2018.

I practise what I sell. This site runs the same consent setup I build for clients, described in How This Site Is Tracked.

I'm based in Yogyakarta (UTC+7), so my afternoons overlap with mornings in Europe, and an AI-native workflow keeps delivery fast without cutting corners.

Questions

Do you work for agencies?

Yes. I work with agencies on their clients' accounts, under your name if you prefer. Your client sees your agency, and I deliver to your standard and documentation.

What access do you need?

Usually access to Google Tag Manager, GA4 and Google Ads, and to the website or CMS where the consent banner is installed. For an audit, read access is enough to start.

Which consent banners do you work with?

The one you already have, as long as it can send Consent Mode signals. I've connected CMPs such as Borlabs Cookie and custom banners like the one on this site.

Is this legal advice?

No. I implement and document the technical setup so your data protection officer or lawyer can review exactly what is collected and when.

How do payment and invoicing work?

Prices are in euros. Every project starts with a fixed quote, and Tracking Care is billed monthly.
