Giesswein records 18% more conversions in Google Ads with JENTIS

About Giesswein

Giesswein is a third-generation family business from Tyrol, Austria, best known for innovating with wool. The launch of their Merino Runners marked a strategic shift toward direct-to-consumer (D2C) sales via a growing international e-commerce store.

Executive Summary

Giesswein selected JENTIS as their server-side tracking solution to ensure high data quality for their marketing efforts. In a direct comparison with Google’s own server-side Tag Manager, JENTIS delivered 18% more conversions in Google Ads, proving to be the more powerful tool for performance optimization, consent handling, and privacy-compliant data use.

Challenge

As Giesswein shifted from B2B to B2C and scaled up D2C operations, data quality became business-critical. Increasing advertising budgets required accurate tracking and conversion attribution — especially during peak periods like Black Friday. Traditional client-side tracking was no longer sufficient due to ad blockers and browser limitations, and early server-side setups didn’t deliver the expected performance.
