Workflows
1. Performance Data Collection
Google Ads — Pull hourly performance:
SELECT
campaign.name,
segments.hour,
metrics.impressions,
metrics.clicks,
metrics.cost_micros,
metrics.conversions,
metrics.conversions_value,
metrics.all_conversions,
metrics.average_cpc
FROM campaign
WHERE campaign.status = 'ENABLED'
AND segments.date DURING LAST_30_DAYS
ORDER BY segments.hour
SELECT
campaign.name,
segments.day_of_week,
metrics.impressions,
metrics.clicks,
metrics.cost_micros,
metrics.conversions,
metrics.conversions_value,
metrics.average_cpc
FROM campaign
WHERE campaign.status = 'ENABLED'
AND segments.date DURING LAST_30_DAYS
ORDER BY segments.day_of_week
SELECT
segments.day_of_week,
segments.hour,
metrics.impressions,
metrics.clicks,
metrics.cost_micros,
metrics.conversions,
metrics.conversions_value
FROM campaign
WHERE campaign.status = 'ENABLED'
AND campaign.name LIKE '%[campaign_pattern]%'
AND segments.date DURING LAST_30_DAYS
ORDER BY segments.day_of_week, segments.hour
2. Bid Modifier Calculation
Formula:
bid_modifier = (time_slot_CPA / average_CPA) ^ -1
Example:
Average CPA across all hours: $50.00
Hour 10am CPA: $35.00
Modifier = ($35 / $50) ^ -1 = 1.43 → +43% bid increase
Hour 2am CPA: $120.00
Modifier = ($120 / $50) ^ -1 = 0.42 → -58% bid decrease
Statistical significance check:
Minimum data thresholds before applying modifiers:
- At least 100 clicks per time slot
- At least 10 conversions per time slot
- At least 14 days of data
- Chi-squared test p-value < 0.05
IF data_insufficient:
Apply conservative modifiers only (max ±20%)
OR group into broader time blocks (4-hour windows)
Modifier guardrails:
| Adjustment Range | Risk Level | When to Use |
|---|
| ±10-20% | Low | Default starting range, limited data |
| ±20-40% | Medium | 30+ days data, 50+ conversions per slot |
| ±40-70% | High | 90+ days data, statistically significant |
| -100% (pause) | Very High | Only with strong evidence (zero conversions, high spend) |
Tiered time block approach:
Instead of 24 individual hour modifiers, group into performance tiers:
TIER 1 — PEAK (highest conversion rate hours)
Modifier: +20% to +50%
Budget allocation: 40% of daily
TIER 2 — STANDARD (average performing hours)
Modifier: 0% (no change)
Budget allocation: 35% of daily
TIER 3 — OFF-PEAK (below average hours)
Modifier: -20% to -50%
Budget allocation: 20% of daily
TIER 4 — EXCLUDE (very poor performance)
Modifier: -90% to -100%
Budget allocation: 5% or 0%

4. Time Zone Considerations
Multi-geo campaign strategy:
OPTION A: Single campaign, schedule in account time zone
Pros: Simple management
Cons: Schedule doesn't match local user times
Best for: Single-country campaigns
OPTION B: Separate campaigns per time zone
Pros: Precise local scheduling
Cons: More campaigns to manage, fragmented data
Best for: US campaigns (4 time zones), global campaigns
OPTION C: Audience-based time zone targeting
Pros: Flexible, data-driven
Cons: Requires enough data per segment
Best for: Mature accounts with conversion data
US time zone campaign structure:
Campaign: Brand_Search_US_Eastern
Schedule: Optimized for EST/EDT
Geo: CT, DC, DE, FL, GA, IN(east), KY(east), MA, MD, ME, MI(east),
NC, NH, NJ, NY, OH, PA, RI, SC, TN(east), VA, VT, WV
Campaign: Brand_Search_US_Central
Schedule: Shift all times +1 hour vs Eastern
Geo: AL, AR, IA, IL, IN(west), KS, KY(west), LA, MN, MO, MS,
MI(west), ND, NE, OK, SD, TN(west), TX, WI
Campaign: Brand_Search_US_Mountain
Schedule: Shift all times +2 hours vs Eastern
Geo: AZ, CO, ID(south), MT, NM, UT, WY
Campaign: Brand_Search_US_Pacific
Schedule: Shift all times +3 hours vs Eastern
Geo: CA, ID(north), NV, OR, WA
5. Platform-Specific Scheduling
| Platform | Ad Scheduling Support | Granularity | Bid Modifiers | Notes |
|---|
| Google Ads | ✅ Full | 15-minute blocks | -90% to +900% | Most flexible. Set in campaign settings. |
| Microsoft Ads | ✅ Full | 15-minute blocks | -90% to +900% | Mirrors Google capability |
| Meta Ads | ⚠️ Limited | Day-level only | No modifiers | Only "Run ads on a schedule" with lifetime budget. No hourly control. |
| LinkedIn | ❌ None | N/A | N/A | No native scheduling. Use campaign start/end dates only. |
| TikTok | ⚠️ Limited | Hour blocks | No modifiers | "Dayparting" in ad group settings. On/off per hour, no modifiers. |
| Reddit | ⚠️ Limited | Day-level | No modifiers | Schedule by day only. |
| Amazon Ads | ⚠️ Limited | Day-level | No modifiers | "Dayparting" for Sponsored Products, hour-level. |
| X (Twitter) | ❌ None | N/A | N/A | No scheduling support. Manage via API toggles. |
Meta workaround for hourly optimization:
Since Meta doesn't support hourly bid modifiers:
1. Use Campaign Budget Optimization (CBO) — Meta's algorithm
adjusts spend timing automatically based on conversion signals
2. For manual control, create separate ad sets per time window
with lifetime budgets and schedule them:
- Ad Set: Morning (6am-12pm) — Lifetime: $X
- Ad Set: Afternoon (12pm-6pm) — Lifetime: $Y
- Ad Set: Evening (6pm-12am) — Lifetime: $Z
⚠️ This requires LIFETIME budget, not daily budget
3. Use automated rules:
- Pause ad sets outside peak hours
- Resume during peak hours
- Increase budget during high-performance windows

Smart Bidding and Dayparting Interaction
IMPORTANT: Smart Bidding (Target CPA, Target ROAS, Maximize Conversions)
already adjusts bids by time of day internally.
RECOMMENDATIONS:
IF using Smart Bidding:
- DO NOT add manual time-based bid modifiers (they stack)
- DO use ad scheduling to EXCLUDE obviously bad hours (-100%)
- DO let the algorithm handle intra-day optimization
- DO analyze hour-of-day reports to validate algorithm decisions
IF using Manual CPC or Enhanced CPC:
- DO apply bid modifiers based on data analysis
- DO start conservative (±20%) and widen over time
- DO review and update modifiers monthly
- DO use separate campaigns if performance variance > 3x between time slots
IF using Maximize Clicks:
- DO apply scheduling to prevent spend during dead hours
- DO apply moderate bid modifiers (±30% max)
