Higher advertising ROI through conversion tracking strategy
Univé
- Customer case
- Technical Web Analytics

Univé continuously analyses the impact of advertisements: how do they contribute to the intended goal? Ads are driven by the conversion of a (potential) customer applying for insurance. The challenge is that not everyone who applies converts into a customer with an insurance contract. All applications are called 'gross conversions'.
Univé aims to consider the activation of insurance (the moment of acceptance) as the true conversion. They call this the 'net conversion'. The goal is to use the advertising budget more efficiently and seize optimisation opportunities. They enlisted the help of our Technical Web Analysts to set up a process for this.
Approach
Our approach consisted of several phases:
Phase 0 - Hypothesis: In close collaboration with Univé’s Data Analysts, we investigated how many of the gross conversions (applications) converted into customers with a contract (net conversions). We observed a difference, clearly highlighting the importance of net conversion.
Phase 1 - Approved insurances: In collaboration with Univé’s Data Engineers, we made a selection of approved insurances. These were linked to an ad click.
Technical explanation: We selected approved insurances using backend data, which is a database containing actual insurance applications. We created a query to filter applications with the status 'activated'.
Phase 2 - Conversion tracking: We ensured that gross conversions were available in the backend with the corresponding cookie and unique transaction code. This allowed us to link the correct data to the correct transactions (see phase 3).
Phase 3 - Selection: We eventually combined all selected approved insurances (phase 1) with the gross conversions (phase 2). This combination created a selection of transactions that we could send to Google as net conversions.
Phase 4 - Conversion implementation: We then sent this selection via a script through Google Campaign Manager to Google Ads, so the net conversion was registered as a conversion in Google.
Result: cost reduction and customer impact
Since the implementation in February, the Return on Advertising Spend (ROAS) has increased, indicating a more efficient use of Univé’s advertising expenses, resulting in better results per euro spent. The Cost Per Order (CPO) has also decreased, which is a positive development.
A key benefit of the new approach is the increase in the acceptance ratio. By focusing on net conversions, this ratio has risen, saving time and costs for the acceptance department, allowing them to focus on other tasks.
Future
Currently, net conversion is sent directly to Google Ads. In the future, we plan to send the conversion to Tealium (the Tag Management System and Customer Data Platform). This will enable Univé to easily share it with various advertising platforms, such as Pinterest, Meta, and Google Ads, while ensuring GDPR compliance.
Additionally, Tealium offers the possibility to send conversion data to various analytics tools, allowing for more extensive data analysis and even more effective use of the advertising budget. This will help Univé become even more relevant to its members.
