Ads are only eligible for conversions if users have either clicked or viewed the ads.
Explanation:
The correct answer is **true** because ads are eligible for conversions only if users have either clicked or viewed the ads. In the context of Amazon DSP and similar advertising platforms, conversions are typically tracked and attributed to ads that a user has interacted with, either through a click or a view. This is because clicks and views are considered signals of user engagement with the ad, and only these interactions are used to link the conversion back to the ad. If a user has not interacted with the ad in some way, it is difficult to attribute any conversions to that particular ad, making it ineligible for conversion credit.
