Google Ads Tracking · Setup Project
Google Ads Conversion Tracking: custom GTM with consent architecture. Done right once.
Standard GA4 + Consent Mode often loses 25-45% of conversion data in my practice. I build the custom variant, clean data foundation that Smart Bidding actually works on.

Who does it
Mijo Jurisic, Google Ads consultant, founder of MJ Marketing.
Working in Google Ads since 2021: self-taught on own online projects, deep dive into auction mechanics, conversion tracking and search-engine logic. 2023-24 as a Google Ads consultant on behalf of Google, responsible for direct Google Ads customers and top agencies in the DACH region. Across my career, 500+ Google Ads accounts and €22M in media budget under direct responsibility.
Since 2024 I have run MJ Marketing as its owner: I work directly with SMEs and local service providers, and I still work with enterprise clients and agencies. No junior handover. No lock-in.

Setup process
Three phases. Usually 2-3 weeks from briefing to live.
- Week 1
Discovery & architecture
I map your conversion paths (form, call, appointment booking, checkout steps), decide tag-manager strategy (Custom GTM vs. server-side), and define consent architecture. Output: technical spec document.
- Week 2
Build & test
Custom GTM container set up with all tags, triggers and variables. Consent layer (cookie banner) integrated. Testing in preview mode with all edge cases: consent acceptance, refusal, cross-device sessions.
- Week 3
Launch & handover
Live launch with 48h monitoring. Handover documentation with tag map, trigger logic and maintenance notes. 30-min walkthrough call with your team so you can make smaller changes yourselves.

What I build
Three components of Google Ads conversion tracking, documented for handover.
01
Custom GTM container
Instead of GA4 standard templates: hand-built tag architecture with named triggers, variables for each conversion action. Clean naming convention so your team can maintain it later.
02
Consent architecture
Own cookie banner (no Cookiebot lock-in), trigger logic that respects what the user chose. GDPR-compliant but not overly pessimistic: Consent Mode with data, not 0% data on refusal.
03
Server-side tracking (where useful)
For e-commerce, long conversion paths, cross-device scenarios: server-side container via Cloud Run or own infrastructure. iOS-14 losses almost fully reversed, but only where the effort pays off.
Fixed price
Project-based. Three tiers by complexity.
Delivery usually in 2-3 weeks. Handover documentation included. I want your team to maintain it themselves.

What's not included
Ongoing maintenance (tag adjustments when your website changes, new conversion actions etc.) is not in the fixed price. Optional maintenance retainer (priced by scope), or your team does it themselves, that's what the handover doc is for.
Project price
Fixed price with clear scope, payment before project start.
Delivery time
Usually 2-3 weeks from discovery call.
External costs
Server-side hosting (Cloud Run etc.) separate, typically €15-40/mo.

“I hired MJ Marketing to optimize our Google Ads campaigns, and Mijo did a great job! Within a few weeks we received more qualified enquiries than ever before. Our cost per click went down while the conversion rate went up. Absolutely recommended!”
Google review
“As a small business, we were advised and supported by Mijo as part of his Google Ads management. He introduced us to the world of Google Ads step by step and explained everything in detail. … Since then, our campaigns have been running more efficiently and achieving better results.”
What you don't get
Anti-bullshit guarantee for conversion tracking.
What other tracking setups do badly, and I explicitly don't:
No Cookiebot lock-in
You aren't tied to a €500/mo consent vendor. I build or integrate a cookie banner you keep. If you want to switch later, you can.
No lock-in to agency GTM
The container runs on your GTM account. You keep admin access. On termination I can cleanly exit. The whole build stays functional.
No GA4 default templates
GA4 has auto-track templates that look like a lot but deliver wrong data. I build hand-crafted tags with clear logic, even though it's more initial effort.
No promises without server-side
Anyone promising "100% iOS-14 recovery" without server-side is lying. Server-side is the only method that genuinely helps, and I only do it when the effort fits your case.

Setup briefing
30 minutes. We scope the project.
You explain conversion paths, platform, use cases. I say which tier fits (Standard / E-Com / Server-Side) and deliver a fixed-price offer usually within 48h after receiving all necessary info. If you don't book, that's also fine, no sales follow-up calls.
Fixed price after briefing. No hidden charges.
