Bid Optimization Skill

Analyzes Google Ads performance data and generates bid adjustment recommendations. Produces ready-to-use Google Ads Scripts based on Brainlabs patterns.

Safety Guardrails

Read-only by default. This skill:

• Analyzes data and outputs recommendations only
• Never auto-applies bid changes
• Generates scripts that must be manually reviewed and pasted into Google Ads
• Requires explicit user approval before any changes take effect

Optimization Strategies

Day-Parting (Hour-of-Day)

Adjusts bids based on hourly conversion performance. Identifies:

• Peak conversion hours → increase bids
• Low-performing hours → decrease bids
• Uses 24/7 scheduling pattern from Brainlabs

Device Modifiers

Analyzes performance across Desktop, Mobile, Tablet:

• Calculates CPA by device vs campaign average
• Recommends bid modifiers within -90% to +300% range
• Weights modifiers by conversion volume confidence

Audience Targeting

Optimizes bids for:

• In-market audiences based on ROAS
• Remarketing lists by conversion rate
• Custom audiences by CPA performance

Workflow

1. Analyze Performance Data

Run scripts/analyze-bids.py with campaign export data:

python scripts/analyze-bids.py --input campaign_data.csv --output recommendations.json

Input formats supported:

• Google Ads CSV export
• Google Ads API JSON response
• Google Sheets URL

2. Review Recommendations

The script outputs:

• High CPA keywords to reduce bids (CPA > target × 1.3)
• High ROAS keywords to increase bids (ROAS > target × 1.2)
• Day/hour patterns with statistical significance
• Device modifier recommendations
• Estimated impact on spend and conversions

3. Generate Google Ads Script

Run scripts/generate-script.py to create deployable JavaScript:

python scripts/generate-script.py --recommendations recommendations.json --template day-parting

Templates available:

• day-parting - Hour-of-day bid adjustments
• device - Device bid modifiers
• bid-adjustment - Keyword/ad group bid changes

4. Deploy (Manual)

1. Copy generated script
2. Open Google Ads → Tools → Scripts
3. Create new script and paste code
4. Preview before running
5. Schedule for hourly execution

Templates

See templates/ folder for Google Ads Script templates:

• bid-adjustment-template.js - Basic bid adjustment patterns
• day-parting-template.js - 24/7 scheduling with hourly modifiers
• device-bid-template.js - Device platform bid modifiers

Bid Modifier Bounds

Default safety limits:

• Minimum: -90% (0.1x multiplier)
• Maximum: +300% (4.0x multiplier)
• Day-parting: -50% to +50% recommended
• Device: -90% to +100% typical range

Data Requirements

For reliable recommendations:

• Minimum 30 days of data
• At least 30 conversions per segment
• Statistical significance threshold: 95%

Low-data segments receive weighted modifiers to prevent over-optimization.
