More tracked conversions enable scalable tracking

The overview

Klickimpuls, a digital performance agency based in Linz, Austria, was using Google Cloud for Server-side Tracking but faced technical complexity and high costs that limited the solution to their largest clients. When TAGGRS came along, they decided to give it a try. Fast forward to today: Klickimpuls relies on TAGGRS to support 16 and counting clients across e-commerce and lead generation, boosting tracking accuracy and ensuring better privacy compliance.

In this case study, you’ll discover how TAGGRS helped Klickimpuls improve data quality, scale their tracking efforts, and deliver clear, measurable results for their clients.

“For one client, for example, we were measuring about 10% more conversions. And suddenly we had much more room for the campaigns to spend or to scale. With this, we were able to spend more, get more reach and optimize the performance.”
- Andreas Hofer, MSc, Head of Performance Advertising @ Klickimpuls

The challenge

Before adopting TAGGRS, Klickimpuls relied on Google Cloud Platform for Server-side Tracking, but the technical complexity and high infrastructure costs made it unsustainable for most small and medium clients.

“The setup and the maintenance of the Server-side Tracking via Google Cloud was not so easy. And another issue was the pricing. So it was very expensive, also if you’re a very small client with not that much traffic. And so it was only feasible for the biggest clients for us.”
- Andreas Hofer, MSc, Head of Performance Advertising @ Klickimpuls

Plus, growing privacy restrictions, like iOS14 tracking limitations and GDPR consent regulations, caused a noticeable decline in conversion accuracy and data reliability. With only client-side setups and GA4 to rely on, Klickimpuls needed a more scalable, privacy-compliant solution to recover lost data and maintain campaign visibility.

Compared to Google Cloud, TAGGRS emerged as a simplified, affordable, and scalable alternative, offering faster onboarding, strong compliance integration, and thorough documentation. Inspired by trusted Google Ads experts and TAGGRS’s competitive pricing, Klickimpuls successfully integrated the solution to expand Server-side Tracking for 16 clients across e-commerce and lead generation.

The approach

Client onboarding

Klickimpuls relies heavily on the TAGGRS dashboard to monitor vital metrics (e.g. browser distribution, consent rates, and total server request volumes). These insights help quickly identify potential issues, such as drops in consent rates or browser-specific behaviors. Andreas shares, “I normally take a look into TAGGRS dashboard to see the browser distribution, the consent rate… the total numbers of requests.” Then, a tailored tracking strategy is created depending on each client’s unique needs.

“You have to truly understand how tracking works: click identifiers, cookies, consent, and browser behavior—to see why traditional methods fall short and why robust solutions are essential.” - Andreas Hofer, MSc, Head of Performance Advertising @ Klickimpuls

Multi-channel tracking

TAGGRS supports Klickimpuls in fine-tuning conversion tracking across Google Ads, Meta , and Google Analytics 4.

Google Ads

Klickimpuls sets up server-side conversion tracking in parallel with client-side tracking to ensure data reliability before fully switching to server-side data. As Andreas explains, “Klickimpuls tracks the server conversions parallel to the client. If the numbers make sense, we are switching to the server conversions only.”

USE CASE SPOTLIGHT

Margin-based ROAS + offline conversions

“You can store your margin data in a Firebase, Firestore database, and you can use this with a variable on the server-side Tag Manager”

For e-commerce clients, Klickimpuls feeds product margin data into the GTM server container via a Firestore database, allowing margin-based ROAS optimization for more precise campaign measurement.

In the lead generation sector, TAGGRS is used to track qualified leads and offline conversions, which is particularly important for automated campaign types like Performance Max. Andreas adds, “In the lead gen sector, for example, you should try to incorporate offline conversions to measure qualified leads and sales: not only the website leads.”
