The Search Monitor is now offering Coupon Monitoring in their reports.
They are able to detect when affiliate marketers use coupon codes without permission to drive traffic through coupon sites.
With this service, online retailers will be able to monitor usage of coupons meant only for use in campaigns outside of the affiliate marketing channel or for specific authorized affiliates.
Customers using The Search Monitor can enter coupon codes when setting up their campaigns. The coupon codes are then monitored on coupon sites.
If a code is published, it will appear in reporting and an email alert will be sent.
