Top-down approaches like Media Mix Modeling (MMM) and incrementality measurement complement last-touch by estimating causal impact without user-level data, though they provide strategic rather than granular insights.
A Single Source of Truth (SSOT) system can deduplicate conflicting attributions.
Marketers must understand trade-offs and use multiple methods together for a fuller picture.
