Does CPC matter for a Awareness campaign?

Short answer: not really, and here’s why
An Awareness campaign isn't trying to earn clicks, and Meta isn't optimizing to make them cheap, so whatever CPC shows up as here is closer to noise than signal. A high or erratic CPC on an Awareness campaign isn't a problem to solve, it's just a metric being asked a question it was never built to answer.

Adamigo provided the Awareness CTR and CPM figures. No Awareness-specific frequency data was available in research; the reversed frequency logic is a reasoned judgment call based on how brand recall generally works, not a cited benchmark.
