Recency Window: What It Is, Key Features, Benefits, Use Cases, and How It Fits in Programmatic Advertising
Recency Window is a foundational concept in **Paid Marketing** that helps teams decide *how far back in time* a user action should remain eligible to influence targeting, bidding, personalization, and measurement. In **Programmatic Advertising**, where decisions are automated and occur in milliseconds, the Recency Window acts like a time-based filter: a purchase yesterday might be highly meaningful, while a site visit six months ago may be irrelevant (or even misleading) for today’s ad decision.
