Distribution Efficiency
Definition
Distribution efficiency measures how much qualified attention, asset, learning, and outcome value a system produces per unit of fully loaded cost.
Full explanation
Distribution efficiency is a portfolio measure across the Distribution Economics Stack, not a single ratio. The Distribution Efficiency Score weights attention, asset, learning, outcome, operational, compounding, and risk-adjusted components with cap rules so one strong dimension cannot mask a critical weakness.
Why it matters
A campaign can look cheap on raw CPM and still be strategically weak. Distribution efficiency forces multi-output evaluation before reallocation decisions.
