Shopify + Meta Ads Attribution: See True ROAS Without Pixels
Meta says 4.2x ROAS. Your bank account disagrees. Causality Engine uses causal inference on your GA4 data to reveal which Meta campaigns actually drive incremental sales, no pixel required.
Channel comparison
Meta Ads: reported vs. actual contribution
What Meta Ads claims vs. what causal inference reveals
Why Meta's numbers don't add up
- iOS 14.5+ blocks 40-60% of conversion tracking. Meta can't see what it can't track
- Meta's attribution window inflates ROAS by claiming credit for organic purchases
- View-through conversions count someone who saw an ad but never clicked, and bought anyway
- Cross-device journeys are invisible: the TikTok discovery → Google search → Meta retarget path gets 100% Meta credit
- Ad blockers affect 30%+ of your audience. Meta reports zero for those users

How Causality Engine solves Meta attribution
- No pixel dependency, analyzes your GA4 data directly, immune to iOS tracking blocks
- causal inference separates true Meta-driven sales from coincidental conversions
- Shapley values fairly distribute credit across Meta, Google, TikTok, email, and organic
- Confidence scores on every channel, know which ROAS numbers you can trust to 95% certainty
- GA4 CSV upload, results in 5–10 min. No code, no DNS changes, no onboarding call. Native Shopify integration is on the roadmap

Frequently asked questions
Do I need the Meta pixel installed?
No. Causality Engine doesn't use the Meta pixel at all. We analyze your GA4 data and Shopify orders to determine which Meta campaigns actually cause sales. This means iOS privacy changes don't affect our accuracy.
How is this different from Meta's built-in attribution?
Meta has a financial incentive to make its ads look good, it's marking its own homework. Causality Engine is independent. We use causal inference to determine true incremental impact, not last-click or view-through proxies.
Will this work with my Advantage+ campaigns?
Yes. Causality Engine evaluates the causal impact of all Meta campaign types, including Advantage+, ASC, and manual campaigns. The methodology works regardless of Meta's campaign structure.
How long does setup take?
Two minutes. Connect your Shopify store and GA4 property. No pixel installation, no developer needed, no 90-day learning period.
