Server-Side Tracking Pipeline Audit

Audits the entire server-side measurement pipeline that backs every paid channel's modeled conversion data. Without server-side tracking in 2026, expect 30-40% conversion data loss from iOS ATT, ITP, and aggressive ad blockers — that's the gap between what's actually happening and what your bid algorithms can see.

This sub-skill is technical and deep. It's NOT the same as ads-attribution, which audits the attribution model sitting on top of these events.
