Challenge
VaultLine's performance team was optimizing against attribution that was quietly decaying. Browser changes and consent drop-off meant their ad platforms were seeing fewer conversions than actually happened — and bidding worse because of it.
Strategy
We treated tracking as infrastructure, not a one-time setup. The goal was a measurement layer that stayed accurate as privacy controls tightened, with event match quality high enough that bidding algorithms could trust the signal.
Execution
We built a server-side tagging layer through Google Tag Manager, configured consent mode v2, deduplicated events across client and server, and instrumented enhanced conversions for the platforms that supported them. We then set up monitoring so match quality was watched, not assumed.
