When You Use the Wrong Window, You Kill the Right Campaigns
New customer acquisition often converts slower than retargeting
If you judge NCA or TOF campaigns through a 7-day lens, you create false negatives — then you cut the spend that was building future customers.
At the same time, when there are no clear decision thresholds, teams argue endlessly:
“Should we increase budget?”
“Is this working?”
“How long do we wait?”
“Is this working?”
“How long do we wait?”
“Without a time window and decision boundaries, your data has no context.”
Expectation =
The Correct Attribution Window + Scale / Chill / Kill Zones
A) Set the Correct Attribution Lookback Window (Based on Intention)
Recommended windows:
New Customer Acquisition
30 days
Top of Funnel Cold Traffic
30 days
Retargeting / Bottom of Funnel
7 days
Why this matters:
TOF and NCA performance shows up later. BOF shows up fast. Using the wrong window guarantees the wrong decision.
B) Define Your Scale / Chill / Kill Zones (Based on the North Star KPI)
How zones work:
Chill Zone: acceptable band for the KPI
Scale Zone: better than chill (increase budget)
Kill Zone: worse than chill (diagnose; fix or stop)
Example (If Chill Zone for nCAC is $40–$50):
Scale Zone: nCAC below $40
Chill Zone: nCAC $40–$50
Kill Zone: nCAC above $50 (diagnose or stop)
“If your KPI doesn’t match the job, your reporting becomes a trap.”
The Expectation Alignment Loop
Expectation isn’t guessing — it’s the structure that keeps measurement honest.

Changes Everything
Predictable outcomes by campaign type
Correct lookback windows prevent false negatives
Zones eliminate indecision
Protects prospecting + NCA from BOF bias
Makes weekly decisions faster and defensible
