THE METHOD

A scientific method that measures
the true impact.

01 / COMMUTE ZONES

Test and control, drawn around real life.

Maxma splits the US into about 600 proprietary commute zones, each a self-contained local economy around where people live, work and shop. People rarely cross those boundaries day to day, so very little spills between test and control.

Ten times more units to match on means smaller lifts are detectable, holdouts shrink to 10–20% of the market, and even regional campaigns can be tested properly. And because it is geo-based, it avoids the tracking and privacy issues that broke traditional attribution.

02 / OBSERVABLE LIFT

Lift you can actually see.

Compare real outcomes between control and test: no black box, just facts. Easy to explain, hard to refute, so you can win trust from managers, clients, finance or leadership.

WHEN TO TEST

Make testing part of
every marketing decision.

01

Current budget

Measure incrementality at your existing spend level to understand true ROI and optimize allocation.

02

Heavy-up

Test the impact of increasing ad spend to prevent diminishing returns and audience saturation.

03

Dial-down

Reduce spend safely with measured potential missed opportunities to maintain efficiency.

04

New launch

Before scaling a new initiative, test for detectable incremental impact at the lowest possible spend level to minimize risk.

05

Lingering effect

Capture delayed impact in the weeks following advertising campaigns for full attribution.

06

Halo effect

Measure impact across all sales channels including DTC, marketplaces like Amazon, and retail locations.
