Marketing Engineers improves tracking reliability, marketing observability and client trust

Marketing Engineers is a marketing & advertising technology agency from Rotterdam in the Netherlands. They call themselves the “geeky guide” and technical partner of marketing teams. The team helps clients with analytics, first-party data collection, tag management, consent management, server-side tracking and data architecture.

Marketing Engineers wanted to make the website tracking of their clients more reliable, spend less time fixing issues, and give clients more confidence in their own data. For that reason, they reached out to Code Cube.

The challenge

Tracking errors that break trust and waste time

Despite their technical focus, Marketing Engineers faced recurring challenges common to analytics-focused agencies.

Clients’ tracking, tags, dataLayer events and consent mechanisms are complex and constantly changing. Even small front-end changes or updates to themes, consent tools, or third-party scripts often caused certain tags or dataLayer pushes to break. These hidden tracking failures can go unnoticed for weeks or even months and cause data discrepancies between analytics tools, ad platforms, and backend systems.

Marketers face wrongly optimized campaigns because conversions or events aren’t tracked correctly. Managers and CMOs start to lose trust in the data they use for decision-making. And IT teams, often responsible for compliance and security, had little visibility into what the marketing stack was actually doing. This combination leads to undermined trust, reactive debugging, and wasted time across departments.

Marketing Engineers needed a smart, automated way to spot tracking issues early and understand what caused them in order to free up internal capacity for higher-value work.

The solution: Real-time marketing observability with Code Cube

Marketing Engineers added Code Cube’s real-time tracking monitoring to their daily operations giving them full observability over tags, dataLayer pushes, and consent mechanisms.

With Code Cube they now get:

  • 24/7 tag and dataLayer health checks
    Code Cube constantly watches whether tags fire correctly and whether anything (like consent settings or script errors) blocks them. The real-time monitoring ensures issues get noticed immediately, even outside business hours.

  • Smart alerts with clear details
    When something breaks, the alert shows exactly what went wrong and where (which tag or dataLayer event failed, which page or domain, whether consent or script errors blocked it), so debug fixes are targeted and quick.

  • Marketing- and consent observability
    Code Cube makes it clear when events are being blocked for legitimate consent reasons versus when something is broken, helping both marketers and IT stay compliant without losing data quality.

Impact: Full trust in data, less time wasted and true observability

For Marketing Engineers:

  • Cut the time to detect tracking problems from days to hours;
  • Spend far fewer hours on debugging
  • Pro-actively inform clients when there are tracking issues
  • Fewer client escalations about tracking or attribution issues

  • Improved client trust and satisfaction

  • Strengthened pitch with “continuous tracking health monitoring” as part of their offer

  • Free up more time for strategic work instead of fixing broken tags

For marketers:
No more guessing if tags are still firing. Campaigns are properly optimized because data is complete and reliable.

For managers and CMOs:
Peace of mind that the tech stack they invested in actually works. Less undermined trust, fewer disputes about “bad data,” and a stronger foundation for business decisions.

For developers and IT departments:
True observability. Code Cube gives visibility into what’s happening in the marketing tech stack, without building internal tooling or manually checking logs. It’s cheaper, faster, and integrates cleanly with existing governance processes.
