Un cliente ve un anuncio el 1 de abril, hace clic en este el 4 de abril, vuelve a verlo el 7 de abril y compra el producto el 9 de abril. ¿Cuál de las siguientes opciones recibe el crédito por conversión?

The correct answer is the click on April 4th. In Amazon DSP, the default attribution model is "last touch," which means the last interaction (either a click or an impression) that occurred within a defined lookback window before a conversion receives credit. Clicks are prioritized over impressions if both occur within the lookback window. In this scenario, the click on April 4th is the last touchpoint before the purchase on April 9th. The purchase on April 9th is the conversion itself, not the event that receives credit. The impressions on April 1st and April 7th are earlier touchpoints, but the click on April 4th is a stronger, more direct engagement and is closer to the conversion, thus receiving credit under the last-touch model.
