A shopper interacts with ads from two different campaigns from the same brand, they first click an ad promoting the brand's mirrorless cameras and later click an ad promoting the brand’s camera cases. The shopper ends up purchasing the mirrorless camera from the brand. Purchase conversion will be awarded to which campaign?

Amazon Ads attribution assigns purchase credit to the eligible campaign connected to the product that was purchased. The click on the campaign promoting the purchased mirrorless camera is the relevant conversion attribution touchpoint. A later click on an accessory campaign does not receive credit for a different purchased product. This keeps Amazon DSP reporting aligned to the advertised product and attributed sale.
