Taobao's merchant review mechanism mainly includes enterprise qualification review, product quality review, service capability review and credit rating review.

First, merchants need to provide proof of enterprise qualification to ensure the authenticity and legality of the merchant's identity.

Secondly, the product quality review mainly reviews the quality of the product, after-sales service, and supply stability.

Furthermore, merchants need to provide relevant service certificates, such as logistics distribution capabilities, customer service capabilities, etc.

Finally, Taobao will also evaluate the credit of merchants, including store level, rating, reputation level, etc., to ensure that merchants can operate in good faith. These review mechanisms can ensure the safety and reliability of consumers' shopping, and can also promote the honest operation and development of merchants.
