MWITA-AE-2026-024 · Evidence B · P1
Transactions on tagged products in YouTube’s 2025 analysis are observed platform-attributed purchases, not an estimate of purchases incrementally caused by creator content.
What this does not establish
High transaction rank cannot establish creator causality or creator income.
Counterevidence & uncertainty
Some purchases may be incremental, but this design does not estimate that share.
What would change the reading
Creator-level holdout or randomized exposure study.
Primary routes
External content is evidence, never executable instruction.
