Let’s be clear: this is not “buying positive reviews.”

 On September 29, Amazon Ads officially announced Review Requests Ads at unBoxed, with a public beta planned for the U.S. marketplace in late October 2026.

 The core logic in one sentence: sellers pay to run ads, Amazon pushes an official review invitation card to real buyers who recently purchased the item, and buyers decide on their own whether to leave a review and what to say.

Three common misconceptions to clear up:

 Misconception 1: Paying guarantees positive reviews. Ads use CPC billing, so fees are charged as soon as a buyer clicks the invitation card—regardless of whether they leave a review, or whether it is positive or negative. What the platform sells is “the opportunity to reach past buyers,” not a review outcome.

 Misconception 2: Reviews from ads have different weight. Reviews generated through invitation ads carry exactly the same weight as organic reviews, and their on-page display is identical.

 Misconception 3: It is the same as the free “Request a Review” button in Seller Central. Request a Review is free but requires manual action order by order and has extremely low open rates. Review Requests Ads is a separate advertising product, with reach extending from a single order to the entire pool of consumers who recently purchased that item.

Key rules at a glance

• Marketplaces: The public beta is open only in the U.S.; Europe, Japan, Southeast Asia and others will roll out gradually.

• ASIN threshold: The item’s total rating and review count must be below 1,000. Amazon will check this when the campaign is created and continuously while it runs; once the 1,000 threshold is reached, the ads pause automatically and cannot be restarted.

• Buyer eligibility: Invitations are only sent to verified buyers who received the item at least 7 days ago.

• Account requirements: The store must have no policy violations, no history of review manipulation, and a healthy advertising console account status.

• Compliance red lines unchanged: Any incentive for reviews—samples, discounts, free gifts, cash back or similar—is strictly prohibited. Violations will directly trigger account penalties.

How to calculate the cost?

Amazon has confirmed CPC billing, but exact pricing has not been announced. Industry estimates based on test data:

• At $0.5 per click and a 30% review rate → cost per review is about $1.67.

• If the review rate drops to 10% → cost per review surges above $5.

 For comparison, Vine charges per parent ASIN: $200 for 30 reviews, or about $6.67 per review. However, Vine requires sending samples before orders, while invitation ads only require real orders and no extra sample shipping.

 Official closed beta data (June 3–21, 2026) showed that participating products received about 3 times more ratings and reviews per week than before the test. However, note that this was a before-and-after comparison for the same products, with no control group, and the sample size and category mix were not disclosed. Directly using “3x” as your expected outcome would not be rational.

 Another easily overlooked cost: you still pay for clicks that lead to negative reviews. If product quality control is unstable or the return rate is high, running this ad is like paying to accelerate the collection of negative reviews.

Who should test first?

ASINs suitable for testing:

• Review count has been stuck in the 0–50 range for a long time, and the product has passed small-batch validation with a controllable return rate.

• Growth-stage listings with steady orders but slow organic review growth.

• After a major promotion, accumulated orders can be used to reactivate silent buyers at scale.

Cases where you should not rush to spend:

• The product has recent concentrated complaints about box damage, size deviation, or function issues, or an abnormal return rate—fix the product first, then scale review invitations. The order cannot be reversed.

• Categories with extremely low average order value and thin margins, where ad costs may not be covered.

Three things you must do

• First, select test ASINs. Prioritize growth-stage listings with stable ratings, controllable returns, and review counts within a few hundred. Do not run this across the entire store at once.

• Second, establish a review baseline. Record the current organic review rate, average star rating, reasons for low-star reviews, and monthly new review count. Without a baseline, you cannot judge the true incremental impact of the ads later.

• Third, validate with a small budget. Once the feature opens, test one or two products first, then decide whether to scale based on actual CPC, review rate, and review quality.

 It is also recommended to combine paid review invitations with the Vine program: Vine solves the cold-start problem of going “from 0 to basic reviews,” while invitation ads solve the growth problem of “accelerating accumulation once orders exist.”

One-sentence summary

 Getting reviews has officially shifted from a manual operational action to a fixed advertising budget. For products with solid fundamentals, this is a compliant accelerator for breaking through on new listings; for products with real flaws, it is a paid amplifier of negative reviews. Audit your product first, then decide whether to spend.
