How to use VoC Overview to understand customer feedback
Start with Product Insights
Before reviewing the product insights, first check the time fields at the top right of the page:- Last updated on: The most recent data refresh time
- Assessment period: The order period covered by the metrics on the page
Products shown in VoC are categorized as Poor, Fair, and Good based on how they are performing relative to the category average.

Review the product list
After selecting a product group, review the product list to identify which products need attention first.You can use Sort by to reorder the list based on your review needs. By default, the list is sorted so that the products needing the most attention appear first. This helps you quickly focus on the products that may require the most immediate actions.
Understand relative performance
The 'Index' section shows how a product compares against the category average.It helps you understand whether a product is performing above, near, or below the category baseline. In general, a higher rate indicates a higher risk of underperformance, signaling that the product requires immediate attention.

VoC Case Study
Since June 2025, we have launched a Voice-of-Customer (VoC) complaint-correction program to address negative customer feedback. Each week, we selected a number of key SKUs, provided sellers with a consolidated VoC summary, and required corrective actions along with a follow-up report within five days. We then monitored each SKU for 20 days to validate the results.Sellers who reduced their VoC complaints not only avoided penalties but also experienced meaningful order growth. Every recommended solution is typically supported by no less than five real seller case studies. Reducing VoC complaints, therefore improving customer experience, has proven to be one of the most effective levers for driving order volume.
*Please refer to the recommended actions below. These solutions have been successfully implemented by other sellers to address similar issues in their shops.
