What is TOFU / MOFU / BOFU? — Definition for DTC operators

Definition

TOFU (top of funnel), MOFU (middle of funnel), and BOFU (bottom of funnel) describe where a user is in their journey from awareness to purchase. TOFU is cold reach, MOFU is consideration (retargeting engagers, page-viewers), and BOFU is decision (cart abandoners, recent visitors).

How operators actually use it

DTC media plans typically split budget 60/25/15 across TOFU/MOFU/BOFU for a growing brand, with TOFU doing the heavy lifting and BOFU mopping up high-intent users at low CPA. Creative by funnel stage is different — TOFU is hook-driven and educational; BOFU is offer-driven with social proof. Mixing creative across stages (running a 'GET 20% OFF' BOFU ad to a cold audience) destroys efficiency on both ends.

Common pitfalls and honest-cost notes

Brands either over-invest in BOFU (cheap CPA, but you are just paying for orders that would have happened anyway — low incrementality) or skip MOFU entirely (which is where most repeat consideration happens). Run an incrementality test on BOFU specifically — most brands find they can cut BOFU spend 30-50% with no impact on revenue.
