The day is not uniform
A flat daily bid treats 2am the same as 8pm. But shoppers do not buy uniformly across the day — conversion rates, competition, and intent all swing by the hour. Dayparting is simply refusing to ignore that.
Three levers, by the hour
Advanced bidding and budgeting means steering all three of these toward the hours that convert and away from the ones that waste:
- Bids: push higher in high-converting windows, ease off in dead hours.
- Budgets: protect spend for peak hours instead of burning it overnight.
- Placements: lean into Top of Search when intent is highest.
Find your windows
Optimize by efficiency, not raw volume. The hour with the most sales is not always the most profitable; look at revenue per click by hour to find where each dollar works hardest, then concentrate spend there.
