How are merchants rated?
The Merchant Rating System is an integral part of Yahoo!'s program to guarantee a positive, high-quality online shopping experience. The rating system gathers feedback from shoppers about Yahoo! Shopping merchants and then uses the feedback to determine an overall rating for that merchant. The system is weighted so that the merchant's overall rating reflects the majority of customer ratings. If most customers rate the store positively, the rating will reflect this. The overall rating is displayed next to the store name whenever it appears in the Yahoo! Shopping pages.

Use merchant ratings to make more informed purchasing decisions. And, after you place an order, contribute your feedback by filling out a merchant evaluation form.

In the old rating system, merchants who offered excellent customer service were awarded a Top Service icon (Top Service). In the new system, merchants will be awarded stars to denote the level of customer service they offer. A rating of five stars is the equivalent of the old Top Service rating.
