Attribution modeling is a process of assigning credit or value to different marketing channels and touchpoints that influence a customer’s journey and conversion. Attribution modeling can help marketers understand how their marketing efforts work together and optimize their marketing mix and budget.
However, attribution modeling is not a simple or straightforward task. It involves many challenges and limitations, such as data quality, data integration, data privacy, etc. One of the most common and critical challenges is the circular reference problem.
The circular reference problem occurs when the attribution model uses the same data or metric that it is trying to measure or optimize. For example, if the attribution model uses revenue or conversions as an input to assign credit to different channels, then it is creating a circular reference. The attribution model is essentially using the outcome that it is trying to explain or improve as a factor to explain or improve it.
The circular reference problem can lead to inaccurate and misleading results and insights. It can also create a self-fulfilling prophecy or a feedback loop that reinforces the existing biases or assumptions in the attribution model. For example, if the attribution model assigns more credit to the last-click channel based on revenue or conversions, then it will show that the last-click channel is more valuable and effective than other channels. This will then lead to more investment and optimization for the last-click channel, which will then generate more revenue or conversions, which will then confirm the attribution model’s findings.
The circular reference problem can be avoided by using independent and objective data or metrics as inputs for the attribution model. For example, instead of using revenue or conversions, the attribution model can use metrics such as impressions, clicks, visits, engagement, etc. that reflect the exposure and interaction of customers with different channels and touchpoints. These metrics can help measure the contribution and influence of each channel and touchpoint without creating a circular reference.
However, using independent and objective data or metrics is not enough to solve the circular reference problem. The attribution model also needs to account for other factors that may affect the customer journey and conversion, such as customer characteristics, preferences, behavior, etc. The attribution model also needs to use a robust and reliable methodology and algorithm that can capture the complexity and dynamics of the customer journey and conversion.
One of the most advanced and effective methods for attribution modeling is machine learning (ML). Machine learning is a branch of artificial intelligence (AI) that uses data and algorithms to learn from patterns and trends and make predictions and recommendations. Machine learning can help create and implement attribution models that are data-driven, adaptive, scalable, and transparent.
Machine learning can help overcome the circular reference problem by using various techniques, such as:
- Data preprocessing: Machine learning can help clean, transform, integrate, and standardize the data from different sources and platforms to ensure its quality, consistency, and completeness.
- Feature engineering: Machine learning can help extract, select, create, and combine relevant features or variables from the data that can explain or predict the customer journey and conversion.
- Model selection: Machine learning can help choose the best model or algorithm for attribution modeling based on various criteria, such as accuracy, complexity, interpretability, etc.
- Model training: Machine learning can help train the model or algorithm on the data using various methods, such as supervised learning, unsupervised learning, reinforcement learning, etc.
- Model evaluation: Machine learning can help evaluate the performance and validity of the model or algorithm using various metrics, such as precision, recall, F1-score, AUC-ROC curve, etc.
- Model optimization: Machine learning can help optimize the model or algorithm by tuning its parameters or hyperparameters using various methods, such as grid search, random search, Bayesian optimization, etc.
- Model deployment: Machine learning can help deploy the model or algorithm into production and integrate it with other systems and tools.
- Model monitoring: Machine learning can help monitor the model or algorithm in real-time and update it based on new data and feedback.
Conclusion
Attribution modeling is a valuable and essential tool for marketers who want to measure and optimize their marketing performance and ROI. However, attribution modeling also poses many challenges and limitations, such as the circular reference problem.
The circular reference problem can be avoided by using independent and objective data or metrics as inputs for the attribution model. However, this is not enough to solve the problem completely. The attribution model also needs to account for other factors that may affect the customer journey and conversion. The attribution model also needs to use a robust and reliable methodology and algorithm that can capture the complexity and dynamics of the customer journey and conversion.
Machine learning is one of the most advanced and effective methods for attribution modeling that can help overcome the circular reference problem. Machine learning can help create and implement attribution models that are data-driven, adaptive, scalable, and transparent.
