Incrementality-calibrated multi-touch attribution | Calibrates native attribution model that also considers clickstream data | No native MTA model, models attribution through impression-weighted MMM |
Budget optimization recommendations | MMM projections are causally grounded in proven impact | Without incrementality calibration, all recommendations are correlative estimates |
Diminishing returns analysis | Can pinpoint when spend levels go over peak efficiency and signal reallocation to more marginal channels | Without incrementality, diminishing returns don't reflect actual results |
