What are the Best Attribution Tools for Shopify?
The one that answers your question. If Meta, Google or GA4 are missing events from your store, fix the tracking first. If you want one screen for daily operations, pick a dashboard. If you need to know which channel caused your sales, no tracking tool records that: it takes a holdout test or causal inference on your own data.
The Problem with Traditional Attribution
Check it for free: add up the purchases Meta and Google report for last week and set the total next to your Shopify orders for the same week. More claimed orders than real ones means some sales are counted twice. Then cut one channel's spend in one region for two weeks and compare revenue with the regions you left alone.

Enter Causality Engine
Causality Engine applies causal inference to your GA4 export: it estimates what each marketing channel caused, with Direct split back to the channels that sent those buyers, and sets that next to last-click rebuilt from the same export. It works on GA4's channel groups rather than campaigns, it does not connect to ad platforms today, and a read costs €99 once; Pro is €299 a month.
| Feature | Causality Engine | Traditional Tools |
|---|---|---|
| Methodology | causal inference | Rule-based (First/Last Click) |
| Trust signal | A data-health score from 0 to 100 on every channel | None |
| Actionability | A next step per channel, with how to test it | Credit only |
For background, see attribution (marketing) on Wikipedia.

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 a channel can sit in many buyers' paths without causing their purchases. Causal inference estimates what would have happened without the channel, which is the number a budget decision needs.How is Causality Engine different from other attribution tools?
Causality Engine runs causal inference on a GA4 export and shows what each channel caused next to what last-click gave it, with a data-health score and a next step for every channel, while rule-based models give the credit to the first or last touch.
