Amazon has announced an important change to how customer reviews are shared across product variations. It will directly affect how your variation listings perform. Starting February 12, 2026, Amazon will stop sharing reviews across variations that have meaningful differences.
According to the official announcement, the rollout will happen gradually by category and finish by May 31, 2026. This update is about review accuracy, but for sellers, it changes how trust, conversions, and variation strategy work on Amazon.
What exactly is changing?
Until now, Amazon has allowed all child ASINs under a parent listing to share reviews, even when those variations were very different. That means:
A strong variation could carry weaker ones
New variations could launch with hundreds of inherited reviews
Buyers often saw reviews that didn’t actually match the product they were buying
Now going forward, reviews will only be shared when the variations have minor, non-functional differences. If variations differ in a way that affects how the product works, reviews will no longer transfer.
When will reviews continue to be shared?
Amazon confirmed reviews will continue to be shared for:
Color or pattern changes of the same product
Size changes that don’t affect function
Pack size or quantity differences
Secondary scent differences for non-scent-focused products
Model fitments of the same product type
Variations that may lose shared reviews
If your variations differ in features, performance, materials, specifications, or use case, review sharing may stop. This means:
Child ASINs could lose inherited reviews
Star ratings may drop overnight
New variations may start with zero reviews
Conversion rates and ad performance may fluctuate
How does it impact sellers?
Variation structure matters more than ever: If you grouped products together mainly to share reviews, that advantage is fading. Incorrect or aggressive variation setups are now a liability.
Each ASIN’s quality now affects performance: Your listing with weak images, poor A+ Content, unclear differentiation, and low standalone review quality will struggle once reviews stop flowing in from other variations.
Ads become more expensive: Lower reviews and star ratings can reduce CTR and CVR, which directly affects PPC efficiency.
What should sellers do now (before February)?
Amazon will send 30-day advance emails before your listings are affected, but waiting is risky. Sellers who prepare early will have a clear advantage.
Audit your variation listings: Check whether your variations truly differ only in color, size, or quantity. If differences are functional, you can expect review separation.
Strengthen each ASIN individually: Upgrade your images and main image clarity, improve titles and bullet points, add or enhance A+ Content. Sellers need to make sure that each variation clearly communicates its value & benefits to the customers.
Rethink review strategy: Prepare for ASIN-level review generation. Do not rely only on parent ASIN reviews anymore. Now monitor review counts closely during rollout.
Watch performance during rollout: Track conversion rates and ad metrics per ASIN. Then adjust bids and budgets based on the new review reality.
This update clearly shows the shift toward ASIN-level accountability. Amazon is clearly moving toward a model where each product earns trust on its own, not by association. From Amazon's perspective, showing irrelevant reviews hurts the customer experience. From a seller’s perspective, it means each ASIN must now stand on its own.
