Our Affiliate Program tracks transactions based on cookies. Basically, cookies are small pieces of data sent from a website and stored in the user’s web browser while the user is browsing in order to mark it for a later transaction.
When users come to your site and click on the banners or links of a merchant’s site you are affiliated with, a cookie is stored on that user’s browser. Even if they leave the site and come back a few days later to make a purchase, you will still get credit for the purchase and earn your commission.
Depending on merchant’s requirement, the duration of a cookie could last for as long as they want, but by default it is set to 30 days before it expires.
