Workflows

1. Performance Data Collection

Google Ads — Pull hourly performance:

-- GAQL: Performance by hour of day
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

-- GAQL: Performance by day of week
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

-- GAQL: Combined hour × day matrix
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)

Examples

  Mon-Fri 4-6pm:    +5%   (winding down, acceptable)
  Mon-Fri 6-11pm:   -50%  (off hours, keep presence low)
  Mon-Fri 11pm-6am: -90%  (near-pause overnight)
  
  Saturday all day:  -70%  (minimal B2B activity)
  Sunday 4-9pm:     -30%  (some Sunday evening planning)
  Sunday other:     -80%  (near-pause)

PROJECTED IMPACT:
  Current monthly CPA: $68
  Projected CPA after dayparting: $52-58
  Estimated improvement: 15-24%
  Budget reallocation: $1,200/mo from dead hours → peak hours
