How Long Does a Cookie Last?
The standard cookie period for affiliate marketing is thirty
to sixty days.
Some merchants offer 999-day cookies, or even lifetime
cookies.
The most essential element to affiliate marketing is
tracking. Tracking software places a cookie on a user’s
browser when that user clicks on an affiliate link.
The cookie period is determined by the merchant. If the
user performs the desired action within the cookie period,
the affiliate is awarded commission.
