What Is Amazon Vine? What "Vine Customer Review of Free Product" Means

A free product in exchange for a review sounds like exactly what you should be wary of. Vine is different from a seller handing out freebies, and the difference matters when you're reading the reviews.

What Is Amazon Vine?

Vine is a program Amazon runs for sellers who want reviews of new products, sometimes before they launch. Here's how Amazon describes it to sellers (Amazon):

• Who can enroll: sellers on a Professional selling plan who have a role with a brand enrolled in Amazon's Brand Registry, or who sell generic products, and whose offers are fulfilled by Amazon (FBA).
• Which products: new products, or existing ones with fewer than 30 reviews.
• How many: up to 30 units per product, sent to reviewers free of charge.
• What it costs the seller: an enrollment fee per product, from nothing for up to 2 units to a higher fee for up to 30 units (as of November 4, 2026). Amazon says the seller isn't charged if no Vine review arrives within 90 days.

Amazon then matches the product with Vine Voices, who choose which products they want to try.

What "Vine Customer Review of Free Product" Means

That label marks a review written through Vine. It tells you the reviewer got the item free from the program rather than buying it. It doesn't mean the review is positive, and it doesn't mean the seller chose the reviewer.

Vine reviews sit alongside reviews from regular buyers, so you can read both and compare.

Who Are Vine Voices?

Vine Voices are reviewers Amazon invites into the program. According to Amazon, they're selected based on how insightful their published reviews have been, and Amazon matches products with Voices who have purchase history and expertise in that category. Voices request the products they want to try, and Amazon says they share their honest opinions in return (Amazon).

Sellers don't learn who the Voices are. Amazon says it keeps them anonymous, which is why every Vine product ships through Amazon's own fulfillment network.

Vine isn't free money for reviewers: Amazon notes that Voices are responsible for income tax on the products they receive.

Are Vine Reviews Biased? What the Research Found

Researchers from the University of Florida and the University of South Carolina studied every review on more than 5,000 Amazon products. They found that reviewers who got products directly from sellers rated them nearly half a star higher, on a five-star scale, than buyers who reviewed the same products. Vine reviews showed no such rating inflation (Phys.org, 2023).

The researchers point to the middleman. With Vine, Amazon sits between the seller and the reviewer, so the seller doesn't choose who reviews the product. The study was published in Management Science in 2023 (Park, Shin and Xie).

Vine vs. Free Products From Sellers

Until 2016, sellers could arrange disclosed incentivized reviews directly with reviewers. Amazon then shut that system down and removed the existing incentivized reviews. The same study found that afterwards those products' sales fell and they received fewer 1-star reviews, which the researchers linked to more satisfied buyers (Phys.org, 2023).

So treat the two differently:

• A Vine review is labeled, comes through Amazon's program, and in the study showed no rating inflation.
• A review that mentions a free product from the seller, outside Vine, is a warning sign worth a closer look.

How to Read Vine Reviews When You Shop

• Compare Vine reviews with reviews from regular buyers. If both groups say much the same thing, that's reassuring. A big gap is worth noticing.
• Check the dates. Vine reviews can arrive around launch, before many regular buyers have had the product for long. Later reviews show how it holds up.
• Read the low ratings too, from Vine Voices and regular buyers alike, to see what people didn't like.
