AI in Advertising and Marketing Practice Test

Attribution credit is about who gets the sale credit based on touchpoints before a conversion. A click-based approach typically assigns the conversion to the last interaction, meaning the final clicked ad before the sale gets the credit. Because of that, earlier touchpoints—like previous clicks or any ad impressions that didn’t get clicked—don’t receive credit. It also means view-through effects (conversions that occur after seeing an ad without clicking) and assisted conversions (influences from earlier interactions) aren’t captured by this model. The statement captures this limitation directly: click-based attribution credits the last interaction and misses view-through effects and assisted conversions. Impression-based models, by contrast, would credit exposure events themselves, including impressions, which explains why they can pick up view-throughs but can overcredit when there are many exposures. So this option best describes the fundamental difference between the two methods.
