A 'cookie' is a small piece of data sent from a website and stored in the user's web browser while the user is browsing. Cookies were designed to be a reliable mechanism for websites to remember pertinent information (such as items added in the shopping cart in an online store) or to record the user's browsing activity (including clicking particular buttons, logging in, or recording which pages were visited in the past).
When a user clicks on your affiliate link, this action will place a 'cookie' in the browser that they used. That cookie helps us identify if a customer who made a purchase came from your affiliate link. Our cookie also remains on the user's website for the full 7 days.
So if someone makes a purchase, and then comes back to make another purchase before the 7 days, you will still receive credit as long as your affiliate cookie is the last one that was activated.
Another important note, our cookies are not product specific. If your customers buy a course (even the ones you didn't promote to them) within the 7 day cookie window, you will earn a commission from that purchase.
