MMM:

Regress sales on multiple marketing channels + price.

Coefficients tell you how much each channel contributes to sales.

Incrementality:

Calculate how much extra sales you get by increasing spend on one channel.

Example: if coefficient = 1.2, then $10,000 extra spend → 12,000 additional sales units.

Validation:

Compare actual vs predicted in “treatment” periods to estimate true incremental lift.
