• Mono-platform and last click
• Cross-platform and view-based

The correct answer is: Cross-platform and view-based

Explanation: In order to precisely gauge an action campaign’s total value, it’s important to monitor two kinds of conversions in your reporting: cross-platform conversions and view-based conversions. Cross-platform conversions track user activities and conversions across various devices and platforms, while view-based conversions measure user engagement, like viewing a minimum of 10 seconds of an ad or an impression that results in a conversion. By monitoring both conversion types, you can obtain a complete picture of your action campaign’s success and adjust your approach as needed.
