Which conversion metric can give you more insight into how your ads drive conversions on mobile phones, computers, and tablets?

Answer: Cross-device conversion

Explanation: Cross device conversion is the interaction created between the customer or user with the ads. A cross-device attribution report is created for keeping the records of the conversion devices the user uses in its path.

This record is also responsible for displaying the path that the customer take for the completion of conversion. It tells about the advertisement effect the aims and gives more insight about the ideas required for any change in the pan.
