Associate tag
The short tracking ID Amazon adds to your links; it is what ties a sale back to your account. We embed your own tag for each market, so the commission goes to you, never to us.
An associate tag (also called a partner or tracking tag) is the short identifier Amazon ties to your Associates account. Every outbound product link is built with it, so when a sale is attributed Amazon knows which account to credit. On multi-market plans you get a separate tag per marketplace, and each localized page uses the right one. If a product has no valid tag or link in a given market, we do not show it untagged; we hide it with no buy button, because an untagged click is a commission you just lost.
