Key elements of the solution included:
- Server-Side Tracking with JENTIS: Core tracking for donation events, conversions, and campaign interactions was moved into a server-side environment so critical data could still reach analytics and advertising platforms even when client-side tracking was blocked.

Thanks to the new setup implemented by Advance Metrics, we now have better insight into our digital donations. Reliable tracking enables us to optimize our campaigns effectively.
