Broad vs interest targeting: the algo got smarter, your habits didn't

Broad vs interest targeting: the algo got smarter, your habits didn't

Trench note: stacked interests on a nutra offer is a 2019 move.

Narrow interest targeting feels safe — 'health & wellness', 'weight loss', 'keto'. But you're fighting every other buyer for the same tiny, expensive pool, and the algo can't optimize past your fence.

Broad lets the pixel hunt buyers you'd never guess, especially with a strong creative doing the qualifying. The creative IS the targeting now. A weight-loss hook filters the audience harder than any interest box.

— Strong creative + decent budget → go broad, let creative qualify
— Tiny budget / new pixel → interest to seed early signal, then widen
— Niche-y offer (specific condition) → keep some interest guardrails

Go test it.
