Ad Scheduling and Day-Parting Strategies for Google Ad Grant Accounts
Not all hours of the day produce the same results for your Google Ad Grant. A donation that comes in at 10am on Tuesday is worth the same as one at 11pm on Saturday, but the likelihood of getting that donation varies significantly by time and day.
Ad scheduling (also called day-parting) lets you control when your ads show and adjust bid modifiers to increase or decrease competitiveness during specific time periods. For Grant accounts, this is an advanced optimization that squeezes more value from your $329/day budget.
Key Takeaways - Analyze 90 days of data before making scheduling decisions - Most nonprofits see peak conversions on weekday mornings and early evenings - Use bid adjustments (not on/off scheduling) for most campaigns - Keep brand campaigns running 24/7 for CTR protection - Ad scheduling is an optimization, not a requirement
Step 1: Analyze Your Performance by Day and Hour
Before setting any schedule, you need data. Look at at least 90 days of performance:
- Go to any campaign, then click Ad schedule
- Click Day and hour to see the performance breakdown
- Look at: conversions by day of week, conversions by hour of day, CTR by day/hour, and cost per conversion by day/hour
What patterns to look for:
- Which days have the highest conversion volume?
- Which hours have the highest conversion rate?
- Are there hours with zero conversions but significant spend?
- Does CTR vary significantly by time of day?
Common patterns for nonprofits:
- Weekday mornings (9am-12pm): High traffic, good conversion rates (people at work, researching during breaks)
- Weekday evenings (6pm-9pm): Moderate traffic, often highest donation conversion rates (people giving after work)
- Weekend afternoons: Variable; depends on your audience (churches peak Sunday morning; events peak Saturday)
- Late night (11pm-5am): Lowest traffic, often lowest conversion rates (but not zero; crisis services are an exception)
Step 2: Set Up Ad Schedules
In Google Ads:
- Go to your campaign
- Click Ad schedule in the left sidebar
- Click the pencil icon to add schedules
- Select the days and hours you want to target
Two approaches:
Approach A: Bid adjustments (recommended) Run ads 24/7 but increase bids during peak hours and decrease during low-performing hours:
| Time Period | Bid Adjustment | Reasoning |
|---|---|---|
| Peak conversion hours | +20% to +30% | Compete more aggressively when conversions are most likely |
| Average hours | No adjustment | Default bidding |
| Low-performing hours | -20% to -30% | Reduce spend during low-conversion periods |
Approach B: On/off scheduling Only run ads during specific hours. More aggressive but risks missing conversions during "off" hours.
Recommended for most nonprofits: Approach A. Bid adjustments are more nuanced and don't eliminate your presence during any time period.
Step 3: Implement by Campaign Type
Not all campaigns should have the same schedule:
Brand campaign: Run 24/7 with no adjustments. People search your name at all hours, and brand clicks are high-CTR regardless of time. Don't restrict your CTR safety net.
Donation campaign: Increase bids during evening hours (when people are most likely to donate) and weekend mornings. Reduce during late night.
Service campaigns ("food bank near me"): Schedule around your operating hours. If your food bank closes at 5pm, reducing bids after 5pm wastes less budget on clicks that can't convert to a visit.
Educational campaigns: Run during standard hours. Educational content gets consumed during work hours and evenings.
Emergency/crisis services: Run 24/7 with no restrictions. Someone searching for a crisis line at 3am needs to find you.
When NOT to Use Scheduling
- New campaigns with less than 90 days of data: you don't have enough information yet
- Campaigns with fewer than 30 monthly conversions: too little data for time-of-day patterns to be statistically meaningful
- Crisis service campaigns: always-on is essential
- Brand campaigns: always-on for CTR protection
Reviewing and Adjusting
Ad scheduling isn't set-and-forget. Review quarterly:
- Check if peak hours have shifted (seasonal changes, program timing changes)
- Verify that bid adjustments are improving (not worsening) performance
- Adjust modifiers based on the latest 90 days of data
- If Smart Bidding is managing well without scheduling adjustments, consider removing them (Smart Bidding already accounts for time-of-day patterns)
Important note: Smart Bidding already incorporates time-of-day signals into its bid decisions. Adding manual ad schedule bid adjustments on top of Smart Bidding can sometimes cause conflicts. If your campaigns perform well on Smart Bidding without scheduling adjustments, additional scheduling may not be necessary.

Frequently Asked Questions
Will ad scheduling help me spend more budget? Not directly. Scheduling concentrates your budget into specific hours rather than increasing total spend. If you're underspending, keyword expansion and PMax are better levers than scheduling.
Does Smart Bidding already handle time-of-day optimization? Yes. Smart Bidding factors in hundreds of signals including time of day. For most Grant accounts, Smart Bidding's built-in time optimization is sufficient. Manual ad scheduling is an advanced layer for accounts with strong data patterns.
Should I run ads on holidays? It depends. Donors are often more generous around holidays (Thanksgiving, Christmas, year-end). Service seekers still need help on holidays. Adjust based on your specific audience.
Does ad scheduling work the same globally? Yes. The mechanics are identical. Time zones and cultural patterns (work hours, religious observances, weekday vs. weekend behavior) vary by country. Analyze your own data rather than applying U.S.-centric assumptions.
