Dayparting and Ad Scheduling

Spend when the account converts, not evenly around the clock. Reads do not require approval; schedule and modifier changes affect delivery, so confirm before shipping.

Confirm the account: list_connected_accounts.

1. Read time-segmented performance

Review time-of-day and weekday performance only when the platform performance tool returns those breakdowns. Otherwise ask for a platform export. Compare conversions and CPA by time slot over a stable period, not just clicks. Schedule edits require the platform UI when no supported plan field exists.

2. Find the real pattern

• Slots with strong conversion volume and CPA at or below target want to keep or gain bid.
• Slots with spend and clicks but no conversions are candidates to reduce or exclude.
• Watch for thin cells; a single quiet hour is not a trend. Judge on volume, not one day.

3. Set the schedule

Build an ad schedule with bid modifiers per slot: raise where it converts, lower or pause where it does not. Keep changes proportionate; do not zero out a slot on weak data.

4. Apply on approval

Hand the schedule and modifiers to the account owner for the platform UI unless the live plan schema supports them; confirm after it is applied. Re-pull after a couple of weeks to check the pattern held; buyer behavior shifts seasonally (see kill-scale-rules for scaling discipline).

Rules

• Base every slot decision on conversions with volume, not clicks or one-off days.
• Account for the account's real time zone, not yours.
• Report the schedule set and the expected shift in blended CPA.
