Formula

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

Worked example

If 20,000 visitors view a product page and 3,000 later receive ads based on that behavior, those 3,000 users form the retargeting delivery audience for that segment.

Retargeting often shows strong attributed ROAS because intent already exists. Compare it with incrementality, frequency, view-through conversion and MER before over-crediting the channel.

How it works

Retargeting gives teams a named way to govern spend, creative and conversion quality. In the Marketing Refs graph, it links definitions to adjacent metrics, workflows and operating choices instead of leaving the term as isolated vocabulary.
