This comprehensive guide will demystify attribution modeling and provide actionable strategies to transform your CRO approach.

What is Marketing Attribution in CRO?

Marketing attribution is the science of determining which marketing efforts contribute to conversions and by how much. It's about understanding the customer journey from first touch to final purchase, including every interaction in between.

• ROI Measurement: Calculate true return on marketing investments
• Performance Forecasting: Predict future conversion patterns
