The Challenge of Multi-Channel Attribution

Advertising across multiple channels such as Facebook, Google, Instagram, TikTok, and email marketing creates complex customer journeys. Each channel contributes differently at various stages, making it difficult to assign proper credit.

Common attribution models like last-click or linear fail to capture the incremental value and interactions between channels, often leading to:

Over- or under-valuing specific platforms.

Double counting conversions.

Misallocation of budget.

Why Your Attribution Is Confused

When running ads on five or more channels, simple attribution models attribute conversions to the last touchpoint or distribute credit equally without considering causal impact. This results in poor decision-making.
