Budget Allocation & Bidding Strategy
Process
- Collect budget and performance data across all active platforms
- Read
ads/references/budget-allocation.md for allocation framework
- Read
ads/references/bidding-strategies.md for strategy decision trees
- Read
ads/references/benchmarks.md for CPC/CPA benchmarks
- Read
ads/references/scoring-system.md for health score algorithm
- Validate: confirm spend data covers ≥14 days before evaluating kill/scale decisions
- Evaluate budget allocation, bidding strategy, and scaling readiness
- Validate: verify kill list candidates have sufficient data (≥20 clicks or ≥$100 spend) before recommending pause
- Generate recommendations with kill list and scale list
Budget Allocation Framework
70/20/10 Rule
- 70% on proven channels (consistent ROAS/CPA targets met)
- 20% on scaling channels (showing promise, need more data)
- 10% on testing channels (new platforms, audiences, creatives)

Bidding Strategy Evaluation
Google Ads Bidding Decision Tree
Start
├─ <30 conversions/month?
│ └─ Use Maximize Clicks (cap CPC at benchmark)
│ └─ When >30 conv/month → Maximize Conversions
├─ 30-50 conversions/month?
│ └─ Use Maximize Conversions
│ └─ When stable CPA → Target CPA
├─ >50 conversions/month?
│ └─ Use Target CPA
│ └─ When revenue tracking → Target ROAS
└─ Revenue tracking active + >50 conv/month?
└─ Use Target ROAS
Meta Ads Bidding
- Lowest Cost (default): best for volume, may have CPA variance
- Cost Cap: sets CPA ceiling, may reduce volume
- Bid Cap: maximum bid per auction, most control
- ROAS Goal: target return on ad spend
- CBO vs ABO: CBO for proven campaigns, ABO for testing
LinkedIn Bidding
- Cost Per Send (CPS): for Message Ads
- Maximum Delivery: for Sponsored Content (recommended)
- Manual CPC: for tight budget control
- Target Cost: for predictable CPA
TikTok Bidding
- Lowest Cost: maximize conversions within budget (volume)
- Cost Cap: set maximum CPA (efficiency)
- Bid Cap: maximum bid per impression
- Budget ≥50x CPA per ad group for learning phase exit
Microsoft Bidding
- Mirror Google strategy but bid 20-35% lower
- Enhanced CPC for manual campaigns
- Target CPA / Target ROAS for automated
Scaling Assessment
Ready to Scale (Green Light)
- CPA consistently below target for 2+ weeks
- ≥50 conversions per week (learning phase exited)
- CTR stable or improving
- ROAS above target
- No creative fatigue signals
20% Rule
Never increase budget by more than 20% at a time:
- Week 1: $100/day → $120/day
- Week 2: $120/day → $144/day
- Week 3: $144/day → $173/day
- Monitor 3-5 days after each increase for performance stability
Scaling Methods
- Vertical: increase budget on winning campaigns (20% rule)
- Horizontal: duplicate winning campaigns to new audiences
- Platform expansion: add budget on new platforms
- Geographic expansion: test new markets/regions
- Format expansion: test new ad formats on same platform
Kill List Assessment
3x Kill Rule
- Any campaign/ad group with CPA >3x target → flag for pause
- Review spend in last 14 days with no conversions → flag for pause
- Creative with CTR >50% below platform benchmark → flag for creative kill
Kill Decision Framework
| Scenario |
Data Required |
Action |
| CPA >3x target |
≥7 days data, ≥20 clicks |
Pause immediately |
| No conversions |
≥$100 spend or ≥50 clicks |
Pause and diagnose |
| CTR <50% of benchmark |
≥1,000 impressions |
Kill creative, test new |
| ROAS <50% of target |
≥14 days data |
Reduce budget 50% or pause |
MER (Marketing Efficiency Ratio)
MER = Total Revenue / Total Marketing Spend
- Assess blended efficiency across all platforms
- Target MER varies by business: 3x-10x depending on margins
- Use MER to evaluate overall health, not just per-platform ROAS
- Incrementality testing recommended for MER accuracy
