Formula

Attribution Window = defined numerator / defined denominator over a consistent reporting period
Numerator
The primary counted outcome or cost used in Attribution Window.
Denominator
The population, event count or time period used to normalize Attribution Window.
Reporting window
The date range used consistently across inputs.

Worked example

If the attribution window is 30 days, a click on March 1 can receive credit for a purchase on March 20 but not for a purchase on April 10.

Attribution windows change reported performance without changing customer behavior. Compare results across consistent windows and validate with incrementality where possible.

How it works

Attribution Window gives teams a named way to make growth decisions measurable and economically grounded. In the Marketing Refs graph, it links definitions to adjacent metrics, workflows and operating choices instead of leaving the term as isolated vocabulary.
