The Complexity of Black Friday Attribution

Holiday sales periods like Black Friday involve multiple simultaneous campaigns across channels, flash sales, and heavy discounting. Customer journeys become non-linear with multiple touchpoints close together.

Standard attribution models fail to handle:

Overlapping campaigns.

Rapid channel switching.

Data noise from promotions.

Last-click and simplistic models attribute almost all credit to the final touchpoint, ignoring the build-up of awareness and consideration.

Causal Inference Brings Clarity

Causality Engine applies Bayesian causal inference to disentangle overlapping marketing effects and quantify the incremental impact of each channel and campaign.
