Mid-February has passed, and many sellers might feel a chill when they open their backend: why did the number of reviews for some variants suddenly decrease?

Don't panic, it's most likely not due to review deletions, but rather a split.

According to Amazon's official notice previously, starting from February 12, 2026, the rules for sharing reviews among variants will be officially tightened. Simply put, from this day on, only variants that are functionally identical and differ only in appearance (such as color, size) or packaging quantity will continue to share reviews.

If your variants involve performance differences, different materials, flavor distinctions, changes in applicable demographics, or even bundled combinations—even if it's just a slight difference that affects user experience—the reviews will be forcibly split.

What does this mean?

The good old days of "if one product is a hit, the whole family eats well" are over.

Looking back at the past few years, variant merging has almost been a "required course" for every seller. Launching a new product? No problem, just merge it with an old link, share the reviews, and the conversion rate instantly levels up. Slightly different colors or styles? Stuff them all into one variant group and let the best-selling sub-variant carry the others along.

This approach essentially exploits loopholes in the system—using the reputation of Product A to sell Product B. Now, Amazon's logic has changed: every independent product should have its own accumulation of reviews.

This brings at least three levels of impact on sellers' operational thinking.

First, the leverage of "using old links to bring in new products" is completely invalidated.

In the past, when developing an iterative product, even if there were upgrades in functionality or optimizations in materials, many people tended to merge it under an old ASIN and rely on past achievements. But from now on, as long as your new product differs from the old one in terms of functionality, performance, or materials, reviews must be accumulated independently.

This means that every product iteration is a new "cold start." You can't rely on three-year-old reviews to sell this year's upgraded product. This also forces sellers to focus more on the competitiveness of the product itself—if the new product isn't strong enough and doesn't have its own review accumulation, it's a brand-new link that has to go through the difficult climb from 0 to 1 again.

Second, the product selection strategy needs to be adjusted: from "many and miscellaneous" to "few and precise."

In the past, when creating variants, many people liked to "fill up"—launch seven or eight colors for one style, and then divide each color into three or four sizes, almost turning a listing into a department store. Because of review sharing, even if some variants sold poorly, they could still piggyback on the reviews of best-selling items and survive.

But now it's different. Each variant has to independently face the test of conversion rates. Those SKUs that were already hard to sell and had poor conversion rates will be eliminated by the market faster without the support of the main link's reviews, becoming backlogged inventory.

This is actually forcing sellers to do subtraction. Instead of making ten mediocre variants, it's better to concentrate resources on refining two or three truly competitive sub-products. Under the new rule of independent reviews, each SKU has to stand on its own, and no one can always hide behind others.

Third, the focus of operations shifts from "merging techniques" to "content cultivation."

Since you can't rely on merging to piggyback on reviews, the quality of each variant's listing becomes unprecedentedly important.

How to write the title, how to dig pain points in the five points, how to showcase differentiation on the A+ page—these details that might have been covered up by "merging variants" are now key to determining conversion rates. For example, if you're selling cups and the only difference is color, that's fine, you can continue to share reviews. But if your variants include both regular water cups and thermoses, they must be separated. At this time, the listing for the thermos needs to clearly explain its insulation duration, material craftsmanship, applicable scenarios—these details, which might have been glossed over after merging, now need to be explicitly explained separately.

At the same time, a new traffic entrance is rising, which might offset some of the pain brought by "review splitting."

At the beginning of 2026, Rufus AI's weight is rapidly climbing. Data shows that 250 million users worldwide have used Rufus, and buyers who use it have a transaction probability more than 60% higher. This AI assistant based on conversational understanding will pop up contextual questions below the search box—for example, "What are some waterproof shoes suitable for outdoor hiking?" "Are large coats suitable for adults weighing 180 pounds?"—and then recommend products that best match the user's intent to consumers.

What does this mean? It means that the source of traffic is shifting from "searching keywords" to "answering questions." If your listing can accurately answer these contextual questions, Rufus will push you to the right people, even if you're a new product or don't have review accumulation.

So, the operational logic of 2026 is undergoing a subtle shift: on the one hand, the "communal pot" of reviews is broken, and each SKU has to prove itself independently; on the other hand, the traffic entrance of AI recommendations is opening up, providing more opportunities for new products to overtake in the bend.

For sellers accustomed to the "merge-review-order" trilogy, this indeed brings discomfort. But in the long run, this may not be a bad thing. When reviews can no longer be "borrowed back and forth," when each product has to speak for itself, sellers who truly focus on product development and understand user needs will be more visible.

After all, whether it's algorithms or rules, the ultimate goal is the same: to let consumers buy truly good things.
