Campaign Analytics

Production-grade campaign performance analysis with multi-touch attribution modeling, funnel conversion analysis, and ROI calculation. Three Python CLI tools provide deterministic, repeatable analytics using standard library only -- no external dependencies, no API calls, no ML models.

Output Formats

All scripts support two output formats via the --format flag:

• --format text (default): Human-readable tables and summaries for review
• --format json: Machine-readable JSON for integrations and pipelines

python scripts/attribution_analyzer.py campaign_data.json --format json

# Custom time-decay half-life (default: 7 days)
python scripts/attribution_analyzer.py campaign_data.json --model time-decay --half-life 14

Funnel Analysis

Scripts

1. attribution_analyzer.py

Implements five industry-standard attribution models to allocate conversion credit across marketing channels:

| Model | Description | Best For | |-------|-------------|----------| | First-Touch | 100% credit to first interaction | Brand awareness campaigns | | Last-Touch | 100% credit to last interaction | Direct response campaigns | | Linear | Equal credit to all touchpoints | Balanced multi-channel evaluation | | Time-Decay | More credit to recent touchpoints | Short sales cycles | | Position-Based | 40/20/40 split (first/middle/last) | Full-funnel marketing |

2. funnel_analyzer.py

Analyzes conversion funnels to identify bottlenecks and optimization opportunities:

• Stage-to-stage conversion rates and drop-off percentages
• Automatic bottleneck identification (largest absolute and relative drops)
• Overall funnel conversion rate
• Segment comparison when multiple segments are provided

3. campaign_roi_calculator.py

Calculates comprehensive ROI metrics with industry benchmarking:

• ROI: Return on investment percentage
• ROAS: Return on ad spend ratio
• CPA: Cost per acquisition
• CPL: Cost per lead
• CAC: Customer acquisition cost
• CTR: Click-through rate
• CVR: Conversion rate (leads to customers)
• Flags underperforming campaigns against industry benchmarks

Best Practices

1. Use multiple attribution models -- No single model tells the full story. Compare at least 3 models to triangulate channel value.
2. Set appropriate lookback windows -- Match your time-decay half-life to your average sales cycle length.
3. Segment your funnels -- Always compare segments (channel, cohort, geography) to identify what drives best performance.
4. Benchmark against your own history first -- Industry benchmarks provide context, but your own historical data is the most relevant comparison.
5. Run ROI analysis at regular intervals -- Weekly for active campaigns, monthly for strategic review.
6. Include all costs -- Factor in creative, tooling, and labor costs alongside media spend for accurate ROI.
7. Document A/B tests rigorously -- Use the provided template to ensure statistical validity and clear decision criteria.

Limitations

• No statistical significance testing -- A/B test analysis requires external tools for p-value calculations. Scripts provide descriptive metrics only.
• Standard library only -- No advanced statistical or data processing libraries. Suitable for most campaign sizes but not optimized for datasets exceeding 100K journeys.
• Offline analysis -- Scripts analyze static JSON snapshots. No real-time data connections or API integrations.
• Single-currency -- All monetary values assumed to be in the same currency. No currency conversion support.
• Simplified time-decay -- Uses exponential decay based on configurable half-life. Does not account for weekday/weekend or seasonal patterns.
• No cross-device tracking -- Attribution operates on provided journey data as-is. Cross-device identity resolution must be handled upstream.
