What it means
In affiliate marketing, cookie duration the length of time a tracking cookie remains active in a visitor's browser. If the visitor converts within this window, the affiliate receives credit. Common durations are 30, 60, or 90 days.
Why it matters
Whether you're launching a new affiliate program or scaling an existing one, understanding cookie duration helps you make better decisions about commission structures, partner recruitment, and growth tactics. Most SaaS founders run into this concept early and benefit from a clear mental model before they start building.
