Up to 16% more data tracked for 50+ clients

byteffekt, a full-stack marketing agency based in the Netherlands, began experimenting with Server-side Tracking in 2024. Initially choosing Google Cloud, they soon encountered high technical complexity and costly self-hosting. Their objective was to find a cost-effective, scalable solution that could reduce technical overhead while improving data accuracy across their diverse client portfolio, including B2B and B2C sectors with e-commerce and service verticals.

Discovering TAGGRS, committed to making Server-side Tracking accessible for every business, byteffekt decided to pilot it with 12 long-term clients. The results were compelling: an average 10–28% increase in data capture, alongside a 12% conversion uplift for a key e-commerce client. Client satisfaction was high, fueling byteffekt’s confidence to fully migrate from Google Cloud to TAGGRS.

They then established a repeatable workflow including audits, consent management, DNS configuration, and the use of TAGGRS templates to accelerate deployments. By training all marketers on the fundamentals of Server-side Tracking and holding regular refresher sessions, byteffekt overcame bottlenecks and scaled smoothly.

Today, more than 50 of their clients rely on TAGGRS’ tracking, with unified and reliable data powering the marketing performance and campaign optimization.

On the client-side, byteffekt’s team faced significant hurdles in data tracking and marketing attribution due to data discrepancies. Inconsistent reporting between ad platforms like Google Ads and Meta Ads resulted in misaligned dashboards and made it difficult to justify campaign performance and investment decisions.

They initially went server-side by setting up self-hosting via Google Cloud Platform. But this solution demanded excessive time and technical effort, leaving little opportunity for gathering insights and optimizing campaigns. The technical setup and ongoing infrastructure maintenance quickly became overwhelming: “We found the self-hosting very difficult to set up via Google Cloud Platform. It was very technical, and the costs were high,” said Romy.

And not just that. The integration of privacy compliance tools (like cookie banners and consent management) presented further complexities. The privacy landscape is ever-changing, with new regulations and updates requiring seamless integration with tracking platforms. Staying up-to-date while ensuring reliable data capture and compliance became another challenge for the byteffekt.

With TAGGRS, they went all-in on mastering the infrastructure inside out by building their first implementations from scratch. Once confident, they trusted TAGGRS’ templates, tags, and tools to hit the ground running with new setups. They also documented every step meticulously, creating repeatable workflows adaptable even after breaks between projects.

Today, byteffekt uses TAGGRS mainly to support key platforms such as Google Ads, Meta Ads, Google Analytics 4, and e-commerce solutions like Shopify. Their approach focuses on building a solid foundation of Server-side Tracking knowledge, so every marketer understands the essentials. This ensures the team can confidently manage the setup, troubleshoot issues, and scale efficiently while keeping data accurate and compliant.

Key features they rely on include TAGGRS’ Enhanced Tracking Script to resist ad blockers, alongside the Consent Approval Graph to monitor and optimize cookie consent rates. Both are critical for privacy compliance and high-quality data.

Since implementing TAGGRS, byteffekt has seen a notable uplift in data capture and conversion tracking across their client base of 50+. “On average we see between 2% and 16% more data captured across clients. For some, like a hospitality furniture client, conversions improved by 12%,” says Romy Brookhuis. These early successes quickly translated into client satisfaction, making it easier to roll out TAGGRS to more accounts and build stronger, trust-driven partnerships.

byteffekt also treats cookie consent rates as a KPI, monitoring and optimizing acceptance monthly. For example, they found that using a pop-up banner drives the highest consent rates – consistently achieving 70–85% – which directly improves data quality and tracking reliability.

By stabilizing data collection and enhancing attribution accuracy, TAGGRS has empowered byteffekt to prove marketing ROI more transparently, justify strategic budget decisions, and deepen client relationships focused on long-term growth and performance optimization.
