Amazon Is Splitting Your Variant Reviews Before May 31. Most Sellers Won't Notice Until ACoS Spikes.

Between February 12 and May 31, 2026, Amazon is splitting reviews across every variation family with functional differences. Flavours, formulations, specs, generations, formulas. Reviews aren't being deleted. They're being redistributed. And the visible review count on your listings is dropping in ways most sellers aren't catching until it hits their ACoS.In this episode, I cover what actually changed in Amazon's review sharing policy and which variations are still safe. Why this is a PPC problem before it's a review problem, because your ads get hit first when social proof drops and click-through rates soften. The Vine enrolment trap catching sellers who did everything Amazon told them to do, where one enrolment per parent means you can't re-enrol individual children once reviews are separated. And the three risk zones (green, orange, red) for auditing your own catalogue this week.I walk through a real client example with 12 supplement flavours that went from a consolidated review count across the family to individual counts per variation overnight. The listings that had been riding shared social proof suddenly stood on their own, and the campaigns running against them felt it immediately.There are three moves you can make before the May 31 deadline. This episode gives you all three, plus when DSP demand generation becomes the right response to a social proof gap that listings alone can't fix.
