Amazon is ending the payment of referral fees to associates in North America using pay-per-click (PPC) to get traffic. This is effective beginning May 1st.

The change is not temporary. Amazon will not reinstate payment of referral fees to paid search associates. They say the decision to make the change is based on their review of how they invest their advertising resources.

For items ordered by customers before May 1st, but don’t ship before that date, the referral fee rates users were eligible to earn previously will still apply as long as items were placed in a shopping cart before then.

No accounts will be closed as long as users cease paid search activities and remain in compliance with Amazon’s Associates Operating Agreement (like by sending users to Amazon sites through links on your site).

The company sent affiliates the following email laying out what’s ahead (via Marketing Pilgrim):

    Dear Amazon Associate:

    The Amazon Associates Program

That FAQ page with more information can be found here.

A MarketingVOX article notes, "In another effort to bolster net revenue at the expense of Associates, last month Amazon debuted a program called Product Ads, which enables third-party e-commerce sites to promote their own items on Amazon product pages."

eCommerce sellers seem to be fairly content with Amazon. Disgruntled eBay sellers often sing praise for the site as an alternative.
