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.
