We’re providing clarification on key Amazon Vine policies about review aggregation and review limits.

We aggregate reviews at the parent ASIN level, not the product variation level. We recommend that you enrol all related product variations together, plan your ASIN mergers strategically and consider review limits if you decide to merge products after they have received Vine reviews.

Each store has the same limits on the number of Vine reviews that can be retained, based on the following enrolment tiers:

• Top tier: Enrol 11 to 30 units to retain up to 30 Vine reviews.
• Middle tier: Enrol 3 to 10 units to retain up to 10 Vine reviews.
• Free tier: Enrol 1 to 2 units to retain up to two Vine reviews.

When you merge two or more separate parent ASINs under a new parent ASIN, only the maximum number of reviews for your highest enrolment tier will be retained. For example, if you merge two products that are enrolled in the top tier with 30 reviews each, your new parent ASIN will only retain the 30 highest-quality reviews.
