Affiliate Cookie Duration Explained: Why It Makes or Breaks Your Income
Affiliate cookie duration is the window between when someone clicks your link and when a purchase still counts as your referral. Longer cookies capture more delayed purchases. RankRocket Pro offers a 90-day cookie, while Amazon gives just 24 hours. A 90-day cookie can earn 3-5x more than a 24-hour cookie on the same traffic.
Frequently Asked Questions
What is a good affiliate cookie duration?
60-90 days is the sweet spot. RankRocket Pro offers 90 days, which captures 95%+ of delayed purchases. Anything under 30 days loses significant revenue on considered purchases.
Why does Amazon only have a 24-hour cookie?
Amazon can afford a short cookie because their conversion rate is extremely high (people buy impulsively on Amazon) and they dominate ecommerce. Most other programs need longer cookies to capture delayed decisions.
Do cookies work across devices?
Traditional cookies only work on the device and browser where the click happened. Some programs use cross-device tracking, but most don't. This is why email capture is valuable as a backup.
Can cookies be deleted or blocked?
Yes, users can clear cookies or use privacy browsers that block them. Some programs use server-side tracking as a backup. Cookie blocking affects approximately 15-25% of affiliate clicks.
What happens when an affiliate cookie expires?
After expiry, any purchases by that visitor are no longer tracked to you. The commission is either lost or attributed to the next affiliate whose link the visitor clicks.
