Amazon Reviews are the most consequential product reviews on the planet. They are also the most commercially complicated: the reviewer, the seller, the platform and the advertiser are all participants in the same ecosystem, and the rules around what is and isn't allowed have changed several times.
Amazon Reviews are integrated into product pages. Anyone with an Amazon account that meets a minimum spend threshold can leave a review. Reviews tied to a purchase made on Amazon carry a "Verified Purchase" badge. The platform moderates against community guidelines, with rules against incentivised reviews, paid reviews and review manipulation.
The platform also runs the Vine programme, in which selected reviewers receive products free in exchange for honest reviews — labelled distinctly so consumers can see the relationship.
Sellers use Amazon's Brand Registry, sponsored ads and Vine programme to build review presence. Some legitimately request reviews from customers post-purchase via Amazon's "Request a Review" feature. The grey market — where third parties offer to influence reviews outside the rules — has been the subject of repeated enforcement actions by Amazon and by regulators including the UK's CMA.
Amazon Reviews is the only place on Earth where a consumer can confidently judge a kettle on the basis of one review by a reviewer whose previous reviews include a hammer, a romance novel, a USB cable and "this banana stand". The Verified Purchase badge is doing real work, the moderation is doing genuine work, and the sheer scale of human commentary on consumer goods is — depending on your mood — either the great democratic feat of the early 21st century or a kind of slow-rolling small-print apocalypse.
Amazon Reviews are useful when read carefully and dangerous when read lazily. Three reading habits pay off: filter by Verified Purchase, sort by most recent, and skim the three-stars where the most useful texture lives. For products with fewer than 100 reviews, weight the written content over the average. For products with thousands of reviews, watch for variation-page pooling and for sudden bursts of reviews around launch.
That Amazon has confirmed the reviewer bought the item on Amazon. It does not mean the reviewer is impartial — only that the purchase happened.

No. Amazon's policies prohibit paid removal. Sellers can flag reviews that break the rules and Amazon's moderators decide.
Yes — listings with multiple variations sometimes pool reviews across them, which can blend feedback on different items.
