Announcement reposted from Amazon:
Our Brand Referral Bonus program helps brand owners earn a bonus on sales driven by off-Amazon marketing campaigns.
In our new Seller University module, “Earn a Brand Referral Bonus from non-Amazon advertising”, you’ll find out if you’re eligible, and how to set up, earn, and use your Brand Referral Bonus.
When you direct non-Amazon marketing traffic to Amazon, you earn a bonus averaging 10% of the sale of the promoted product, and any brand products purchased by the customer in the next two weeks. The bonus is provided as a credit on your seller referral fees.
