<b>Case #012: The four hours that ate the profit</b>

A call-center lead offer, mid-ROI and frustrating. It hovered at 18% for a week — alive, barely, never enough to scale with confidence. $140/day, steady mediocrity.

We pulled the hourly breakdown and the chart told a brutal story. The campaign made money for twenty hours a day and set it on fire for four.

— Hours 9am-1am: strong, 60%+ ROI on the bulk of conversions
— Hours 1am-5am: catastrophic, leads generated but the call center was closed

The offer paid on a connected call, not a form fill. Leads we generated at 2am sat in a queue until morning, went cold, and never connected. We were paying full click price for leads that could not, structurally, convert because no human was awake to call them back.

Four hours of dead spend were dragging the daily average from "scalable winner" down to "barely breathing."

— Added dayparting: ads off 1am-7am
— Daily spend dropped from $140 to $108
— But the wasted $32/window was pure loss eliminated

The arc:
— Pre-dayparting: $980/week, 18% ROI
— Post-dayparting: $756/week, 64% ROI

We spent less and made more, because every remaining dollar landed in hours where a lead could actually become a sale.

The lesson: on a call-based payout, your profitable hours are only the hours someone can answer the phone — daypart to the advertiser's operation, not to the traffic's availability.
