Buy Buttons are great. But can we check from which websites the sales come?
For example: A friend of us has a good blog or webside. We give him the buy button code. Now he make sales over his side. We will give him some percentages or discounts as thanks.
How can we check how much he sold or how many order (and which) he generated?
It's easily trackable via Google Analytics Referral tab & Ecommerce Conversion (if you configured with Enhanced Ecommerce setting) :)
