Shopify Attribution: See What Each Channel Caused

Shopify is the source of truth for what sold. It is not the source of truth for what caused the sale. Causality Engine runs causal attribution on your store's GA4 history and returns what each channel caused next to last-click, with a data-health score and a next step for every channel, in 1–2 minutes. No pixel, no SDK, no app to install.

Why Shopify alone cannot tell you what is working

  • Shopify shows orders and referral source but each ad platform also claims the same orders in its own dashboard
  • Channels routinely add up to more than 100% of real orders shipped, which is mathematically impossible
  • Shopify cannot distinguish channels that caused a sale from channels that merely touched the visitor
  • Built-in attribution settings only redistribute credit by rules, never measure incrementality
  • When you change attribution windows or models, the numbers shift but reality does not

How Causality Engine extends Shopify

  • Independent causal attribution: estimates what would have sold without each channel
  • What each channel caused, next to last-click, with a data-health score so you know how hard to lean on each number
  • No pixel, no app install, no engineering ticket: runs on one file, the Attribution paths export from GA4 as a CSV
  • A next step per channel, and receipts that check against your own GA4 export, make a budget move defensible in a finance meeting
  • Results in 1–2 minutes on a GA4 export (12 months or more reads best)

How to set up Shopify attribution

  1. Export your GA4 data

    Export 12 months or more of GA4 data. Longer reads better. The Attribution paths report downloads as one CSV.

  2. Upload the file

    Drag it into Causality Engine. No Shopify app to install, no permissions to grant.

  3. Read your causal numbers

    What each channel caused, next to last-click, in 1–2 minutes.

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 nothing to install on Shopify and nothing to grant in the admin.
  • Why does the causal read credit my channels with less than my ad platforms claim?
    Shopify and each ad platform claim credit for the same orders, which is why their numbers add up to more than 100% of real sales. The causal read shares your revenue out once, by what each channel caused, so no order is counted twice.
  • How is this different from Shopify's built-in attribution settings?
    Shopify's attribution settings redistribute credit by rules (last-click, first-click, model-based). Causal attribution measures whether each conversion would have happened anyway, then credits only the incremental ones.
  • Does it work on past data?
    Yes. That is the native mode. Upload a GA4 export (12 months or more reads best) and the model runs on it directly. No tracking ramp-up.
