Starting from February 12, 2026, Amazon will adjust the way reviews are shared between product variants. Reviews will only be shared between variants with non-functional differences such as color, size, and packaging, while variants with substantial differences in function, material, and structure will no longer share reviews.

Background and Purpose of the Adjustment

The purpose of Amazon's adjustment is to solve the following problems:

1. Misleading Reviews: In the past, variants with significant functional differences (such as clothing made of different materials, electrical appliances with different power) shared reviews, causing buyers to see reviews that did not match the actual product they purchased, leading to returns or negative reviews.

2. Improve Review Authenticity: By strictly limiting the scope of review sharing, ensure that the reviews buyers see closely match the target variant, improving the accuracy of purchase decisions.

3. Crack down on "Review Scratching" Behavior: Prevent sellers from quickly accumulating reviews by merging variants with significant functional differences, maintaining a fair competitive environment on the platform.

Core Rules After Adjustment

Types of variants allowed to share reviews:

1. Color or pattern differences: The product functions are the same, only the visual style is different (such as T-shirts of different colors).

2. Size or shape differences: The functions are the same, but the size or shape is different (such as 3-layer and 5-layer ladder storage racks, large and extra-large bedding).

3. Packaging quantity or capacity differences: The products are the same, but the quantity or capacity is different (such as 250 ml and 500 ml shampoo).

4. Secondary odor differences: The odor is not the main characteristic of the product (such as different fragrance types of fragrance-free cleaning products).

5. Adaptation model differences: The design is the same, only the adaptation object is different (such as the same phone case suitable for different mobile phone models).

Types of variants prohibited from sharing reviews:

1. Performance or power differences: Core specifications are different (such as laptops with different memory, electric drills with different power).

2. Platform compatibility differences: Suitable for different devices or systems (such as computer-specific headphones and game console-specific headphones).

3. Model or generation differences: Different naming models or product generations (such as different models of printers).

4. Bundled product differences: The main product and "product + accessories" bundle (such as a single camera and a camera + lens set).

5. Taste, ingredient or formula differences: Core differences that affect the experience (such as chocolate-flavored and vanilla-flavored protein powder, pet food with different meat sources).

6. Main odor differences: The odor is the core selling point (such as perfumes and candles of different fragrance types).

7. Material or craftsmanship differences: Affecting performance or touch (such as stainless steel and aluminum kitchen utensils, pure cotton and polyester shirts).

8. Usage cases or user differences: Targeting different groups or needs (such as beginner and professional golf clubs, dry skin and oily skin skincare products).

The Impact of the Adjustment and Response Strategy

Impact on sellers:

1. Review shrinkage for old products: After the review of variants with large functional differences is split, the number of reviews originally accumulated by merging multiple variants will be greatly reduced, and the star rating of some core ASINs may decline due to the exposure of negative reviews, directly affecting the product conversion rate.

2. Increased difficulty in new product cold start: The path to quickly obtain reviews through "merging functionally different variants" has been blocked, and functional new products need to accumulate reviews from scratch, increasing promotion costs and time costs.

3. Advertising data fluctuations: The advertising performance of many sub-bodies is based on the high star rating and high score shared by the parent body. After the review is split, the conversion rate, ACOS, BSR and natural ranking of related ASINs may fluctuate significantly.

4. Increased compliance risks: If you forcibly merge variants with significant functional differences to share reviews, you may trigger Amazon's review, resulting in the delisting of the Listing, account restrictions, and even affect store efficiency.

Response strategy:

1. Immediately review existing variant relationships: Export the Listing in full, focusing on checking whether there are cases where the material, performance or applicable population is obviously different but still merged, and correct the variant theme as soon as possible (such as using "color theme" for color differences, "size theme" for size differences).

2. Proactively split high-risk variants: Proactively split variants with differences that change the core experience, such as material, power, and memory, to avoid panic after passive splitting and bear the loss of traffic plunge.

3. Adjust new product planning ideas: If you want to attract new customers through variants, prioritize multiple packs, combo packs, or upgraded capacity versions, rather than variants with large functional differences.

4. Weaken dependence on "black and gray hat" play methods: Avoid quickly accumulating reviews by merging functionally different variants, focus on product diversification and micro-innovation, accurate keyword research and Listing copywriting optimization.

5. Strengthen the quality of Listing content: Images, high-quality content and copywriting need to clearly convey the unique value of each version to reduce misunderstandings and returns.

6. Accumulate legal reviews: Accumulate legal reviews through Vine and "request review" functions, and treat them as a systematic process, not an option.
