The Amazon Vine Program is a review program whereby Amazon invites selected, respected reviewers – Vine Voices – to test out products that are officially registered in the Vine Program, and offer their true review and feedback. Sellers enroll products that meet qualifications and provide free units to the participants, as long as the participants do not purchase the items. Participants then submit unbiased reviews right on the product’s listing. By having Vine Voice review products, this builds credibility and gains additional reviews. The Vine Program is intended to assist newer products and products with few reviews, gaining increased visibility and credibility, while the reviews do not affect the reviewer’s opinions.
