Attribution Methodology Explained
Traditional marketing attribution relies on rule-based models like last-click or linear attribution that assign credit arbitrarily. Causality Engine flips the script by employing Bayesian causal inference to measure incremental impact.
Why Bayesian Causal Inference?
Marketing channels interact dynamically. Rule-based models fail to capture:
Channel cannibalization where one channel reduces another's effect
Synergistic effects from combined channel exposure
Time-dependent influence on conversions
Bayesian causal inference models the true causal effect of each channel, adjusting for confounders and uncertainty.
Core Concept
Causality Engine estimates the posterior distribution of incremental impact (P(\theta | \text{data})) given observed data, where (\theta) represents channel effects.
Using Bayes theorem:
[ P(\theta | \text{data}) = \frac{P(\text{data}|\theta) \cdot P(\theta)}{P(\text{data})} ]
This approach allows us to quantify uncertainty and update beliefs as new data arrives.
Intelligence-Adjusted Attribution
Our system incorporates prior knowledge and real-time data to adjust attribution dynamically. This method outperforms static rules by reflecting true channel performance.
Refinement Queue
Channels with the highest estimated incremental return on ad spend (ROAS) are prioritized for budget allocation.
Causality Chain Visualization
We visualize the sequence and interaction of marketing touchpoints leading to conversion, providing transparency into the attribution process.
Cannibalistic Channel Detection
Our methodology identifies when one channel detracts from another, enabling smarter budget redistribution.

Key Terms in This Article
Attribution
Attribution identifies user actions that contribute to a desired outcome and assigns value to each. It reveals which marketing touchpoints drive conversions.
Bayesian Inference
Bayesian Inference updates the probability of a hypothesis based on new evidence. It refines marketing attribution by incorporating prior beliefs about channel effectiveness.
Causal Attribution
Causal Attribution uses causal inference to determine which marketing touchpoints genuinely cause conversions, not just correlate with them.
Causal Inference
Causal Inference determines the independent, actual effect of a phenomenon within a system, identifying true cause-and-effect relationships.
Conversion
Conversion is a specific, desired action a user takes in response to a marketing message, such as a purchase or a sign-up.
Linear Attribution
Linear Attribution assigns equal credit to every marketing touchpoint in a customer's conversion path. This model distributes value uniformly across all interactions.
Marketing Attribution
Marketing attribution assigns credit to marketing touchpoints that contribute to a conversion or sale. Causal inference enhances attribution models by identifying true cause-effect relationships.
Touchpoint
Touchpoint is any interaction a customer has with a brand throughout their journey. In marketing attribution, each touchpoint is a data signal to understand marketing impact.

Frequently Asked Questions
What is the main difference between rule-based and Bayesian attribution?
Rule-based attribution assigns credit based on fixed rules, while Bayesian attribution estimates incremental impact probabilistically, accounting for channel interactions and uncertainty.
How does Causality Engine handle channel cannibalization?
It detects negative interaction effects where one channel reduces another's contribution, adjusting attribution and optimization accordingly.
Can the attribution model update over time?
Yes, Bayesian inference allows continuous updating of channel impact estimates as new data arrives.
Is the attribution methodology transparent?
Yes, the Causality Chain Visualization shows how touchpoints contribute to conversions, enhancing interpretability.
Why is incremental impact measurement important?
Incremental impact reveals the true value a channel adds beyond what would have occurred without it, enabling precise budget allocation.
