Amazon keyword bidding is an e-commerce advertising strategy that refers to the behavior of sellers bidding for specific keywords on the Amazon platform to place advertisements.

Sellers can choose to bid for ranking, that is, bid at a higher price than competitors to get higher exposure and more clicks.

When buyers search for specific keywords on Amazon, the ads with the highest bids will be displayed at the top or side of the search results.

This advertising method can help sellers increase product exposure and sales, while also improving consumers' shopping experience.
