I am a big fan of the Bing Cashback program but on the merchant side, I was never to clear on how that worked. I did some research and merchants can sign up here to be included in the Cashback program.
There are actually detailed merchant guides (PDF) and optimization tips (PDF) for Bing shopping available.
At DigitalPoint Forums, I spotted one merchant who was kicked out of the program. Honestly, I have never seen a merchant complain online that his merchant Cashback account was terminated. This is the email he received from Microsoft:
Dear ***,Thank you for your participation in the Bing cashback program.
This letter is to notify you that pursuant to Section 12 of the Bing cashback Merchant Agreement, Microsoft is terminating your Bing cashback Merchant Agreement and DinoDirect's participation in the Bing cashback program.
As per Section 12 of the Bing cashback Merchant Agreement:
Upon termination, suspension or discontinuation of the Program or Merchant's participation in the Program: (a) all Listings will be promptly removed; (b) Merchant remains responsible for a period of 15 days for tracking Qualifying Sales that occurred prior to termination and paying the associated Sales Payouts; and (c) after the conclusion of such period, Microsoft shall refund any outstanding amounts in Merchant's Account.
Clearly, the site that was terminated was Dino Direct, but why exactly, is not clear. I was unable to find the Bing cashback merchant agreement.
