Four services. One expert. No BS.
Everything I do is designed to give you one thing: reliable data you can act on. Monthly subscriptions, async delivery, transparent pricing. No lock-in.
GTM Monitoring & Config
Google Tag Manager is the backbone of your marketing data. When it breaks — and it does, with every CMS update, consent change, or new campaign — you lose conversions, audience data, and ad optimization signals. Often silently.
What's included every month
- Weekly automated health check of all tags, triggers, and variables
- Consent Mode v2 compliance verification (critical for EU businesses)
- Data layer integrity check — values passed correctly to GA4 and ad platforms
- Duplicate tag detection and tag firing order analysis
- 1 hour of configuration changes included (new tags, fixes, updates)
- Monthly written summary — what was checked, what was found, what was fixed
Who this is for
Any business running paid ads or making decisions based on GA4 data. If you use Google Ads, Meta Ads, or any retargeting — broken GTM is directly costing you money through miscalibrated bidding algorithms.
How it works in practice
After you subscribe, I send you a short onboarding form. You share read-only GTM access (5 minutes). I set up automated monitoring within 48 hours. You receive a monthly email summary — no calls, no dashboards to log into, no action required from your side unless you want changes.
GA4 Monitoring & Config
GA4 data quality degrades silently. Events stop firing. Conversion goals drift. Attribution changes after a platform update. Most businesses only discover the problem when a campaign 'mysteriously' stops performing — months after the data went wrong.
What's included every month
- Full event tracking audit — are all key events firing correctly?
- Conversion goal verification — are your most important actions being counted?
- Custom dimensions and metrics integrity check
- Attribution model review — are you seeing the right channels getting credit?
- 1 hour of configuration changes included (new events, fixes, goals)
- Monthly written report with findings and recommended actions
Who this is for
Any business using GA4 to make marketing or product decisions. If you look at GA4 reports to decide where to spend budget — you need to know those numbers are right.
Agency Audit & Oversight
Your agency has a conflict of interest. They're paid to run your campaigns — and they report on how well those campaigns are performing. Who checks their work independently? That's where I come in.
What's included every month
- Cross-referencing agency reports with raw GA4 and tracking data
- Conversion attribution verification — is the agency counting conversions correctly?
- Budget efficiency analysis — where is spend going vs. what's converting?
- Audience overlap and campaign logic review
- Written report with specific findings and recommended questions to ask your agency
What this is NOT
This is not about replacing your agency or finding reasons to fire them. Most agencies do decent work. The issue is accountability and data accuracy. My report gives you the information to have informed conversations with your agency — and to make sure the budget is working as hard as it should.
Who this is for
Businesses spending €5,000 or more per month on paid ads through an agency. At that level, a €200-400/month independent check is one of the highest-ROI things you can do.
Custom Development
Standard GTM setups have limits. Sometimes you need something that doesn't exist out of the box — server-side infrastructure, BigQuery pipelines, complex consent logic, or integrations that require actual code.
What I build
- GTM Server-Side implementation (GCP, custom domain, tag migration)
- BigQuery + GA4 export pipelines and custom reporting
- Custom JavaScript tags and event schemas
- Cookieless and privacy-first tracking architectures
- Complex consent management integrations
- Multi-platform data unification (GA4 + CRM + ad platforms)
How it works
Custom development starts with a 30-minute scoping call. I scope the project, estimate hours, and send a fixed-price proposal. No open-ended hourly billing on projects — you know the cost upfront.
