In which way do view-through conversions help evaluate the success of a Displaycampaign?

● Telling you when customers see but don’t interact with an ad, then later
completing a conversion on the site
● Presenting customers a short survey asking about their experience leading up to the purchase they completed
● Narrowing down the best-performing areas of a Display campaign from placement and audience reports
● Identifying which traffic, exclusively from Display, resulted in conversions
