ASINs, or products, within the Amazon Attribution console are selected at the order level.

The statement is true because Amazon Attribution tracks the performance of marketing channels based on specific products (ASINs) that customers purchase. When you set up an Amazon Attribution tag, you associate it with the ASINs you want to measure. This allows you to see which marketing efforts are driving sales for particular products, rather than just overall sales. Therefore, the selection of ASINs for attribution tracking is intrinsically linked to the order level, as it measures the impact of marketing on actual product purchases within an order.
