The shortlist
In the EU, a Meta pixel on a Shopify store needs the shopper's consent before it tracks them, and so does every pixel-based attribution tool. A causal attribution tool like Causality Engine installs nothing: it reads a GA4 export.

What are the Best Attribution Tools for Shopify?
For a Shopify brand, the useful split is between tools that credit tracked touchpoints and tools that use causal inference to estimate what each channel caused.
The Problem with Traditional Attribution
Most attribution tools assign credit by rules, such as last-click, or by a model fitted to the touchpoints they track. Neither tells a channel that drives new sales from one that captures demand you'd have had anyway, the question causal attribution answers. And every ad platform grades its own homework.
Check the gap for free first: add up the purchases each ad platform claims for last week and set the total next to your Shopify orders for the same week. More claimed orders than real ones means the same sales are being credited twice.
Enter Causality Engine
Causality Engine applies causal inference to a GA4 export and estimates what each channel caused once Direct is split back to the channels that sent those buyers, with last-click beside it. No pixel or code; GA4 channel groups, not campaigns; no ad-platform connections today. A read costs €99 on a GA4 export; Pro is €299/month.
| Feature | Causality Engine | Traditional Tools |
|---|---|---|
| Methodology | causal inference | Rule-based (First/Last Click) |
| Accuracy | A data-health score (0–100) on every channel, and every number checks against your export | A fixed rule, whatever the data says |
| Actionability | A next step per channel, with how to test it | Credit per touchpoint |
Key Features
What each channel caused: Each channel's share of the credit once Direct is split back to the channels that sent those buyers.
Next steps: A next step for every channel (raise, cut or hold, or fix tagging first) and how to test it.
Paths to purchase: The common converting paths from GA4, added up across buyers: the customer journey before a purchase.
Channel performance: Which channels drive incremental value, and which ride on sales that would have happened anyway.

Frequently asked questions
What is marketing attribution?
Marketing attribution is the process of identifying which marketing channels and touchpoints are responsible for driving conversions and sales.Why is causal inference important for attribution?
Because it separates the sales a channel caused from the sales that would have happened anyway, which correlation can't do. That is the difference between moving budget to what works and moving it to what shows up most often in the path.How is Causality Engine different from other attribution tools?
It estimates what each channel caused instead of assigning credit to tracked touchpoints. It reads a GA4 export rather than a pixel, splits Direct back to the channels that sent those buyers, and shows last-click beside it, with a data-health score and a next step for every channel. It works on GA4's channel groups, not on campaigns.
