Ad platforms optimizing toward non-revenue-generating conversions

Spitfire Audio's product ecosystem included a substantial volume of zero-valued offerings alongside premium paid products. Their catalog featured free sample libraries through the LABS programme, promotional bundles, and complimentary content distributed to existing customers. While strategically valuable for user acquisition and retention, these zero-value transactions created significant tracking complications.

These zero-value orders were being tracked identically to revenue-driving purchases, creating misleading signals that undermined campaign performance. Spitfire Audio needed a solution that would preserve visibility into all transaction types while ensuring ad platforms received only clean, revenue-focused conversion data for optimization.

Expert Note

Our objective was to protect campaign optimization from being compromised by zero-valued transactions while preserving complete visibility into all user behavior. By implementing synchronized client-side and server-side filtering with a dedicated zero_purchase event, we ensured ad platforms received only revenue-driving conversion data for optimization, while Spitfire Audio maintained full analytical insight into their promotional strategy performance.
