Privacy Sandbox is Google's initiative to replace third-party cookies with privacy-preserving APIs that still enable advertising use cases. Technologies like Topics API, Attribution Reporting, and Protected Audiences aim to balance user privacy with advertiser needs. These APIs provide aggregated or anonymized signals rather than individual tracking. Attribution Reporting, for example, measures conversions without revealing which specific user converted. For URL shortening services, Privacy Sandbox fundamentally changes click attribution. As third-party cookies disappear, services cannot rely on cookie-based tracking across domains. Short link analytics must adapt to use Privacy Sandbox APIs for conversion measurement, potentially reducing granularity but maintaining aggregate campaign performance data while respecting evolving privacy standards.
