There's no sale to measure a return against; Awareness campaigns exist upstream of any purchase decision, often long before someone is ready to buy at all. Judging an Awareness campaign by ROAS is like judging a billboard by how many people bought something in the next five minutes of driving past it.
Ask your agency this instead
How does this Awareness campaign connect to the Sales or Leads campaigns running alongside it?
Is there a way to see whether people reached here later show up as customers?

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.
