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.

---

Input Requirements

All scripts accept a JSON file as positional input argument. See assets/sample_campaign_data.json for complete examples.

Attribution Analyzer

json
{
  "journeys": [
    {
      "journey_id": "j1",
      "touchpoints": [
        {"channel": "organic_search", "timestamp": "2025-10-01T10:00:00", "interaction": "click"},
        {"channel": "email", "timestamp": "2025-10-05T14:30:00", "interaction": "open"},
        {"channel": "paid_search", "timestamp": "2025-10-08T09:15:00", "interaction": "click"}
      ],
      "converted": true,
      "revenue": 500.00
    }
  ]
}

Funnel Analyzer

json
{
  "funnel": {
    "stages": ["Awareness", "Interest", "Consideration", "Intent", "Purchase"],
    "counts": [10000, 5200, 2800, 1400, 420]
  }
}

Campaign ROI Calculator

json
{
  "campaigns": [
    {
      "name": "Spring Email Campaign",
      "channel": "email",
      "spend": 5000.00,
      "revenue": 25000.00,
      "impressions": 50000,
      "clicks": 2500,
      "leads": 300,
      "customers": 45
    }
  ]
}

Input Validation

Before running scripts, verify your JSON is valid and matches the expected schema. Common errors:

  • Missing required keys (e.g., journeys, funnel.stages, campaigns) → script exits with a descriptive KeyError
  • Mismatched array lengths in funnel data (stages and counts must be the same length) → raises ValueError
  • Non-numeric monetary values in ROI data → raises TypeError

Use python -m json.tool your_file.json to validate JSON syntax before passing it to any script.

---

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

---

Typical Analysis Workflow

For a complete campaign review, run the three scripts in sequence:

bash
# Step 1 — Attribution: understand which channels drive conversions
python scripts/attribution_analyzer.py campaign_data.json --model time-decay

Step 2 — Funnel: identify where prospects drop off on the path to conversion

python scripts/funnel_analyzer.py funnel_data.json

Step 3 — ROI: calculate profitability and benchmark against industry standards

python scripts/campaign_roi_calculator.py campaign_data.json

Use attribution results to identify top-performing channels, then focus funnel analysis on those channels' segments, and finally validate ROI metrics to prioritize budget reallocation.

How to Use

Attribution Analysis

bash
# Run all 5 attribution models
python scripts/attribution_analyzer.py campaign_data.json

Run a specific model

python scripts/attribution_analyzer.py campaign_data.json --model time-decay

JSON output for pipeline integration

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

bash
# Basic funnel analysis
python scripts/funnel_analyzer.py funnel_data.json

JSON output

python scripts/funnel_analyzer.py funnel_data.json --format json

Campaign ROI Calculation

bash
# Calculate ROI metrics for all campaigns
python scripts/campaign_roi_calculator.py campaign_data.json

JSON output

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

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 -- Compare at least 3 models to triangulate channel value; no single model tells the full story.
2. Set appropriate lookback windows -- Match your time-decay half-life to your average sales cycle length.
3. Segment your funnels -- Compare segments (channel, cohort, geography) to identify performance drivers.
4. Benchmark against your own history first -- Industry benchmarks provide context, but 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 -- Scripts provide descriptive metrics only; p-value calculations require external tools.
  • Standard library only -- No advanced statistical 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 -- 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.
