About Giesswein
Giesswein is a third-generation family business based in Tyrol, Austria. Originally known for its wool-based products, the company shifted its focus to direct-to-consumer (D2C) sales with the launch of the Merino Runners, their first wool-based street shoes. Today, Giesswein operates a successful global e-commerce business.
Executive Summary
After removing dark patterns from their cookie banners, Giesswein’s consent rate dropped by nearly 20%. This led to less data being collected and negatively impacted ad performance. However, with JENTIS Synthetic Users technology, Giesswein was able to increase ROAS by 25% by supplying high-quality, non-personalized conversion data to Google Ads. This helped optimize the bidding algorithm, improve targeting, and unlock audiences that were previously inaccessible due to missing consent.
Challenge
The shift to a transparent cookie consent design resulted in a significant decline in user tracking data. With fewer consents, Giesswein lost valuable behavioral and conversion data needed for analytics, attribution, and Google Ads performance. The reduced volume and quality of first-party data made it difficult to target audiences effectively and maintain campaign efficiency.
Solution
To overcome this challenge, Giesswein adopted Synthetic Users by JENTIS. This technology uses machine learning to fill gaps created by missing consent, combining real (consented) data with synthetic, privacy-compliant behavioral and conversion data. These synthetic IDs contain no personally identifiable information (PII) but can still be shared with platforms like Google Ads for campaign optimization.
Results & Impact
- +25% higher ROAS achieved with Synthetic Users
- Maintained and even improved campaign performance despite lower consent rates
- Optimized Google Ads bidding by feeding synthetic conversion data
- Enabled targeting of audiences previously lost due to opt-outs
- Demonstrated strong potential for performance gains in low-consent, high-conversion environments
