There was a viewable video a don September 25 th,anon-viewable display a don September 26 th,a viewable video a don October 1 st,andanon-viewable display a don October 3 rd.The customer purchases the product on Oct 6 th.Whichofthe following receives the credit for conversion?

The correct answer is October 1st because Amazon DSP uses a last-touch attribution model. This model credits the last ad impression that directly preceded a conversion, provided it falls within the lookback window. In this scenario, the viewable video ad on October 1st is the last ad interaction (viewable or non-viewable) before the customer's purchase on October 6th. October 6th is incorrect because it is the date of purchase, not the ad that led to the purchase. September 26th is incorrect because while it is an ad interaction, it is not the last ad interaction before the conversion. The October 1st viewable video ad occurred more recently and is therefore credited.
