The opinions of buyers are fundamental for purchase decisions on Amazon. However, many satisfied buyers do not leave reviews, which affects sellers, since, with few reviews, the probability of purchase and the conversion rate decrease.
To combat this, Amazon has created the Amazon Vine, a review service that seeks to generate authentic and helpful reviews.
Let's see what Amazon Vine is, who can participate, the requirements for test products, associated costs and how to monitor reviews. Also, let's talk about how to become a Amazon products reviewer came and what happens to the products after the review.

What are Amazon's reviews?
Amazon Vine invites customers who have provided reviews of previous purchases to post opinions on new products to help other customers make decisions.
The selected reviewers, known as Vine Voices, receive free products and leave a review.
These reviews are intended to be independent and unbiased, so they may be either positive or negative. Sellers have no influence on, and cannot contact , the reviewers, thus ensuring the impartiality of the opinions.

Who can participate in the Amazon Vine program?
The program is open to both vendors and suppliers. To participate, you must have a vendor or supplier account and provide all the required information in Vendor or Seller Central.
The products are sent directly from Amazon to protect the anonymity of the reviewers.
Requirements for test products
To participate in the Vine program, a product must meet the following criteria:
- The product brand must be registered in the Amazon brand record.
- You must have a maximum of 30 reviews.
- It must be in stock on Amazon through Amazon FBA.
- It must be available at the time of registration.
- You must have an image, description and title.
- It should not be an erotic article.
- The products that require another additional product to be reviewed are excluded from the program, although accessories for popular products are allowed, such as mobile phones.
How much does Amazon come?
Before October 12, 2021, suppliers paid to participate in Vine depending on the product, category and number of reviews. For sellers, the program was free for up to five products.
As of October 12, 2021, a $200 registration fee per ASIN to both sellers and suppliers. A maximum of 30 reviews per product is allowed, which equates to an average cost of $6.67 per review.
The rate is charged once for the main Asin seven days after Vine's first review appears. If the product does not receive a review within 90 days, registration fees are not charged.

How to register a product in the Amazon Vine program?
To record a product on Amazon Vine, follow these steps:
- In Seller or Vendor Central, go to Advertising – Vine and click on "Start registering products with Vine today".
- Enter an ASIN in the text box and click "Start Registration".
- Check information about the product.
- Amazon recommends selecting the option "All in-stock product variations are available to reviewers." Choose a different option if you want to specify the variations requested by Vine members.
- Enter the number of units you are registering. You can register up to 30 products by ASIN.
- Check the registration fees that will be charged.
- Confirm registration, incurred rates and terms and conditions.
- After registration, you will see an overview with "pending reviews", the start date, the units available in stock, the units registered and claimed, as well as the Vine reviews received.
How to become an Amazon Vine products reviewer?
You cannot register or postulate as a Vine products reviewer on your own. But Amazon invites reliable reviewers based on the following parameters:
- Reviewer rank: The more times your review is rated as helpful, the higher your rank will be.
- Comments from other customers: Customers can rate the review, for example, as "helpful".
- Compliance with review guidelines: You must comply with Amazon's review guidelines, such as the length of the text, which must be between 70-300 words.
- Review age: More recent reviews are more significant.
Can Amazon reviewers keep the products?
Vine reviewers must keep the products for a specified period.
One reviewer commented: "You have to keep the products for six months, so you can't sell them. Theoretically, Amazon can ask for them back during this period, although in practice this never happens. After this time, I keep the product.
Another reviewer indicated a longer period: "I have to keep them for two years and possibly answer questions about them." Therefore, the reviewers continue to use the products in their daily lives.
Conclusion
Reviews have a fundamental role in customer purchase decisions, and products without reviews have difficulty selling. Amazon Vine can act as an initial impulse to increase sales of new or unknown products, helping customers to make purchase decisions. However, sellers have no influence on the qualification, so participation in the Vine program does not guarantee positive reviews.
Amazon Vine is a valuable tool for both sellers and customers, because it improves the visibility and credibility of products on Amazon. For reviewers, it offers the opportunity to try new products and share honest opinions, benefiting the entire platform community.
