Affiliate Conversion Window

The affiliate conversion window defines the maximum elapsed time between a user's first tracked interaction — a click, impression, or install — and a qualifying conversion event for which the referring affiliate still receives credit. Once this window expires, any conversion by that same user is treated as organic or re-attributed to a newer traffic source. Operators set window lengths as a contractual term within their affiliate program, balancing partner fairness against data hygiene and affiliate fraud exposure.

The conversion window is related to, but distinct from, the attribution window. The attribution window describes the model used to assign credit when multiple touchpoints compete (first-click, last-click, linear), whereas the conversion window is strictly about time eligibility — regardless of model, a conversion that falls outside the window simply does not qualify. It is also broader than cookie duration: in a S2S tracking or postback environment there is no browser cookie at all, yet the conversion window still governs eligibility via a server-side click ID lookup.

Window length has direct implications for CPA and RevShare commission economics. Short windows (7–14 days) reduce tail liability for operators but can frustrate affiliates driving considered-purchase traffic where users research for weeks before converting. Long windows (30–90 days) improve affiliate yield on high-intent content but widen the fraud surface: click-stuffing attacks specifically exploit long windows by injecting fraudulent click IDs late in the user journey to poach organic conversions.

Proper window configuration also affects commission hold periods and chargeback risk. If a conversion window is set to 30 days but the operator's data shows most high-value users deposit within 48 hours, an unnecessarily long window inflates the pool of disputed conversions without adding partner value. Regular window audits — cross-referenced against FTD timing distributions — allow operators to calibrate terms that are both competitive and defensible.
