The reasons mainly include the following points:

Violations: If merchants violate regulations on the AliExpress platform, such as publishing counterfeit and shoddy goods, false propaganda, malicious order brushing, etc., the platform will demote the merchant.

Transaction abnormalities: If there are abnormalities in the merchant's transaction process, such as too high order cancellation rate, too high refund rate, etc., the platform may believe that there is a problem with the merchant and thus demote it.

Negative review violations: If merchants maliciously guide customers to give good reviews, or take other improper means to obtain good reviews, once discovered, the platform will demote them.

Picture theft violations: If merchants steal or modify other people's pictures on product pictures, the platform will demote them.

Intellectual property infringement: If the products sold by merchants infringe on the intellectual property rights of others, such as trademark rights, copyrights, etc., the platform will demote them.
