Blended-CAC gap is not new-vs-blended ROAS gap
Open one Triple Whale cut. Put blended CAC $ next to contribution CAC $. Gap % is the absolute spread over contribution CAC.
Pair: Blended-CAC gap on Traffic. ROAS sibling: new-vs-blended ROAS gap. Build: Blended CAC.
What you type
Blended CAC $ — Triple Whale blended CAC dollars in the cut (paid + other booked into one CAC).
Contribution CAC $ — Contribution CAC dollars in that same Triple Whale cut.
Gap % = |blended CAC $ − contribution CAC $| ÷ contribution CAC $ × 100. When the gap is fat, reconcile which costs sit in each book — never type a fake gap %.
What not to do
Skip inventing a gap %. Skip pasting a ROAS gap into the CAC fields. Skip using ad-account CAC as contribution CAC. Skip blending skills when one skill owns the skew.
