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: what it caused, next to what last-click gave it, and every number checks against your own GA4 export. No more reconciling Meta's claim against TikTok's claim. The read you bring into the budget meeting adds up.
How it fits your workflow
Export 12 months or more of GA4 data. Longer reads better. Drag the file into Causality Engine. The causal model runs in 1–2 minutes. €99 per run. No Shopify app to install, no admin permissions to grant, no engineering ticket.
Frequently asked questions
Do I need to install a Shopify app?
No. Causality Engine runs on one file, the Attribution paths export from GA4 as a CSV. 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. The read runs on your GA4 export, whichever Shopify plan you are on, and the analysis is the same.
