Causal Attribution for Shopify Stores

Shopify tells you what sold. The ad platforms each claim it. You need one incremental number per channel from the data you already have.

By Joris van Huët, Founder & CEOUpdated 2026-09-09

The problem you are living with

Your Shopify dashboard is the truth about orders. The ad platforms each have their own version of the truth about which ones they caused. Adding up the platform-reported revenue routinely exceeds your actual Shopify orders - that is not arithmetic, it is overcounting. The cost is real: you scale a channel that was capturing demand other channels created, then watch revenue stagnate.

What causal attribution changes

Causal attribution gives you one number per channel that adds up to your real Shopify orders. Incremental ROAS, with a confidence interval. No more reconciling Meta's claim against TikTok's claim against the actual orders that shipped. The dashboard you bring into the budget meeting agrees with reality.

Find your wasted ad spend in 5–10 minutes.

Watch the model work on a sample store first, no signup. Then upload your last 40–90 days of GA4 sessions and get incremental ROAS with confidence intervals. No pixel, no SDK. €99 per read.

Frequently asked questions

Do I need to install a Shopify app?

+

No. Causality Engine runs on your standard Shopify orders export. There is no app to install in the Shopify admin.

Does this replace Shopify's built-in attribution?

+

Shopify's built-in attribution settings redistribute credit by rules (last-click, first-click, model-based). Causality Engine measures whether each conversion was incremental. They answer different questions; we recommend using both for different decisions.

What if I am also on Shopify Plus?

+

Same workflow. Shopify Plus exports the same orders CSV format, and the analysis is the same.
