You can, but it is not recommended. Because using small cards on Amazon to divert traffic directly to independent sites is a violation of Amazon platform regulations.

Amazon has strict policies restricting sellers from directing buyers to other sales channels. Doing so may result in serious consequences such as account bans, product removals, and loss of sales privileges.

If you want to divert Amazon customers to independent sites, you should do so in a legal and compliant manner, such as providing high-quality services and products in Amazon stores, establishing a good brand image and reputation, and allowing customers to actively search for and visit independent sites.

Therefore, it is not recommended to use Amazon small cards to divert traffic to independent sites in a manner that violates platform regulations.
