Causality Engine vs LeadsRx: An Honest Comparison for eCommerce

Causality Engine and LeadsRx both offer marketing attribution solutions, but they are built on fundamentally different principles. LeadsRx provides multi-touch attribution to show you the entire customer journey, while Causality Engine uses causal inference to determine the true, incremental impact of each marketing channel.

For a Shopify brand in the beauty, fashion, or supplement space, the most important question is not just what the customer journey looks like, but what parts of that journey are actually causing sales. LeadsRx is a powerful tool for visualizing the customer journey and assigning credit to various touchpoints, but it is still based on a correlation-based model. Causality Engine, on the other hand, is built to distinguish between correlation and causality, giving you a much more accurate picture of what is actually driving your growth.

The Problem with Multi-Touch Attribution

Multi-touch attribution, as provided by LeadsRx, is a significant step up from last-click attribution. It allows you to see all the touchpoints that a customer interacted with before converting, and to assign credit to each of them. However, it does not solve the fundamental problem with traditional attribution: it is based on correlation, not causality. Even with the most sophisticated multi-touch model, you are still just looking at which channels were touched before a conversion. You are not looking at which channels actually caused the conversion.

Causality Engine, in contrast, is designed to distinguish between correlation and causality. Our platform is built on a foundation of causal inference, which allows us to determine the true, incremental impact of each of your marketing channels. We use a Bayesian framework to model the probability of a sale, given exposure to a marketing activity. This can be represented as:

P(Sale | Ad) > P(Sale | No Ad)

This formula asks: is the probability of a sale, given a user saw an ad, greater than the probability of a sale if they had not seen the ad? This allows us to isolate the true incremental lift of each marketing channel, a concept that a multi-touch attribution platform simply cannot provide. Our Intelligence-Adjusted Attribution feature automatically accounts for confounding variables, giving you a clear picture of what is actually driving growth.
