Software affiliate programs with long cookie durations — why the window matters

The cookie duration (referral window) is how long after a click the program still credits you. It is the most underrated term in affiliate marketing.

Why windows matter more than rates

A 50% rate with a 24-hour cookie pays you only on impulse buys. Business software is not an impulse buy: buyers compare options, check budgets, and ask colleagues. That process takes weeks.

• 24 hours - 7 days: you lose most considered purchases
• 30 days: the common middle ground
• 60 days (Tasskel): covers real business buying cycles, including month-end budget approvals

How attribution interacts with the window

Within the window, programs still need a tie-breaker when multiple affiliates touch the same prospect. Tasskel uses last-click. First-click credits the first eligible touch; last-click credits the most recent eligible touch. Attribution also depends on the program’s tracking and eligibility rules.

What to ask before joining

1. How long is the referral window?
2. Does it reset on a new click?
3. What is the tie-breaker?
