E8 Adjusting bids by time of day
Read this flowchart as text
- Day-parting report: sales & ACoS by hour × weekday (4+ weeks)
- Clear hourly pattern? (ACoS spread > 30%)
- Skip; predictive pacing / default is fine
- Bid rules: −20–40% in weak hours · +10–20% in peak hours (e.g. evenings)
- Budget rule: ensure daily budget lasts into peak hours (D16)
- Re-read report after 3 weeks; adjust; note seasonality shifts
- Same sales at 10–20% lower spend, or more sales at same ACoS
