The Campaign Everyone Assumed Was Fine
The Problem
Paid media for the primary brand ran through an outside agency. The reports looked normal — spend, impressions, the usual dashboard fare — but return on ad spend was 0.83. Less than a dollar came back for every dollar spent. Nobody had flagged it, because "paid media is expensive" is an easy assumption to hide behind.
What I Did
Audited the campaign structure rather than the summary reporting — targeting, creative rotation, bid strategy — and found where spend and conversion had come apart. Moved the whole operation in-house and rebuilt it.
Result
ROAS went from 0.83 to 5.55, on less spend than the agency had been using.
Trusting a report and verifying it are not the same action.
