During holiday periods, advertising costs spike dramatically. CPMs can increase 50-100% during Black Friday week. If you don't adjust your bidding strategy, you'll either get priced out of the auction or overpay for results.
Here's how to adjust bidding for high-competition holiday periods.
Understanding Holiday Competition Dynamics
What changes during peak seasons:
- CPM increases: 50-100% higher than baseline
- CPC increases: 30-60% higher competition for clicks
- CVR increases: Higher purchase intent offsets some costs
- Volatility: Hour-to-hour performance swings
Bidding Strategies for Peak Periods
Strategy 1: Cost Cap Adjustment
Raise cost caps to stay competitive:
- Increase cost caps 20-40% above normal targets
- Monitor closely—don't set and forget
- Be prepared to adjust daily based on results
- Lower caps immediately after peak periods
Strategy 2: Bid Cap for High-Value Conversions
Use bid caps when you know exact customer value:
- Set maximum bid based on lifetime value
- Accept fewer conversions at profitable prices
- Useful when margins are tight
- Requires accurate value calculation
Strategy 3: Value Optimization
Let Meta optimize for highest-value customers:
- Focus on ROAS targets rather than cost per conversion
- Allow flexibility in CPM/CPC for better LTV customers
- Works well when customer values vary significantly
- Requires good conversion value data
Strategy 4: Lowest Cost with Guardrails
Maximum flexibility with spending controls:
- No bid constraints—let algorithm optimize
- Control through budget limits instead
- Monitor results and adjust budgets
- Works well for aggressive scaling
ROAS Target Adjustments
When to Lower ROAS Targets
- During BFCM weekend when volume is critical
- For prospecting campaigns building future audiences
- When customer LTV is high relative to first purchase
- If inventory needs to move
When to Maintain ROAS Targets
- For retargeting warm audiences
- When margins are thin
- For products with low repeat purchase rates
- During post-peak periods
Budget Pacing During Peak Days
Front-Load Strategy
Spend more early in the day:
- Morning shoppers often have higher intent
- CPMs sometimes lower early in the day
- Secure impressions before competition heats up
Responsive Pacing
Adjust throughout the day:
- Monitor performance hourly during peak days
- Shift budget to best-performing time blocks
- Pause underperformers quickly
- Scale winners aggressively

Common Holiday Bidding Mistakes
- No adjustment: Using normal bids during peak
- Over-constraining: Too-tight caps that prevent delivery
- Slow reaction: Not adjusting as conditions change
- Post-peak overspend: Not reducing bids after holidays
- Ignoring LTV: Only looking at immediate ROAS
Post-Holiday Bid Reset
After peak periods:
- Immediately reduce bid caps to baseline
- Monitor for spend inefficiency
- Expect lower volume at lower costs
- Document learnings for next peak season

Frequently Asked Questions About Holiday Bidding Strategy
Plan for 30-50% bid increases to remain competitive. Monitor actual CPMs and adjust—some years require more, some less. The key is flexibility and real-time responsiveness.
Most advertisers do better with cost cap or bid cap during peak periods. Fully automatic bidding can overspend when competition spikes. Manual controls give you guardrails.
CPMs typically begin rising mid-November, peak during BFCM weekend, stay elevated through December 20, then drop sharply. Plan budget allocation around this curve.
Often yes—if customer LTV is strong. A 2x ROAS during peak volume can outperform 4x ROAS at normal volume. Factor in lifetime value, not just immediate returns.
Monitor hourly during BFCM weekend. Be prepared to make adjustments every 2-4 hours based on performance. Pre-plan your bid adjustment thresholds before peak days.
