A 60/30/10 tier blend beats single-tier ROAS by 20-35%

Micro 60% ██████ | Mid 30% ███░░░ | Macro 10% █░░░░░

Concentrating budget in one tier leaves money on the table. Micros (10-80k) supply cheap, high-intent conversion. Mids (80-500k) add scale. A macro anchor (500k+) lends credibility the smaller tiers borrow.

— Micro CPV floor: $0.02-0.04, best direct response
— Mid: $0.05-0.09, scaled reach
— Macro: $0.12-0.25, awareness + halo

The macro's halo lifts micro conversion when audiences see the brand 'everywhere.'

So what: weight budget to micros for efficiency, keep one macro for the halo — pure single-tier underperforms the blend.

Benchmark: n=48 portfolios — blended structures beat single-tier ROAS in 79% of cases.
