There is no doubt that a review is one of critical factors for manufacturs or sellers for their product. Postivie and good review should lead a product to increasing in sales. So Amazon is running a paid review program called Vine Program. Manufactueres and publishers will pay to receive reviews for their products.
- Total paid reviews are 47 and unpaid are 8362. So total paid reviews are only 0.56% for unpaid reviews
- 5 star review for Paid Review(Vine Program) is about 32% while Unpaid Reviews are about 52%
Total 5 star paid reviews are 15 while unpaid 5 star reviews are 4332, which means Vin program review has only 0.56% on 5 star reviews. In addition, 5 Start review ratio on Vin program is 32% while unpaid reviews are 52%. So I can state that Vin program has very limited impact on reviews on Watch Review data. If I can run total number and ratio for other ratings such as 4, 3, 2 and 1 star reviews I can get much solid conculsion for Vin program.
