They require customized universal event tracking set up correctly for that product, are correct because they describe key aspects Marco is interested in tracking when people who were shown an ad and didn't click on it, but still went on to purchase at a later date.Using which feature in the Microsoft Audience Network can Marco track this?

The selected answer option, View through conversions, is correct because it specifically tracks situations where users have seen an ad but did not click on it, yet went on to make a purchase at a later time. This feature in the Microsoft Audience Network allows advertisers like Marco to measure the effectiveness of their ads beyond just clicks, by capturing conversions that occur after an ad impression. View-through conversions are especially useful in understanding the impact of ads on user behavior and purchase decisions, even if those users did not engage with the ad immediately but converted later. This gives a more comprehensive view of the campaign's performance and its influence on potential customers who may have been persuaded by the ad's presence.
