Shopify + TikTok Attribution: Prove the Impact Last-Click Misses
TikTok creates demand that converts on Google and Meta. Last-click attribution gives TikTok zero credit. Causality Engine reveals TikTok's true incremental impact on your Shopify revenue.
Why TikTok looks bad in your dashboard
- TikTok is a discovery channel — it creates demand but conversions happen days later on other channels
- Last-click attribution gives zero credit to TikTok when a customer discovers on TikTok then buys via Google
- 21-day consideration cycles for beauty/fashion mean TikTok's impact is invisible in 7-day windows
- TikTok's own pixel has the same iOS tracking limitations as Meta — 40-60% data loss
- When you cut TikTok based on bad attribution data, Google and Meta ROAS drops 2-4 weeks later

- Causal inference measures the downstream revenue created by TikTok — even when conversion happens on Google

Frequently asked questions
TikTok shows low ROAS in my dashboard. Is it actually working?
Likely yes. TikTok is a top-of-funnel discovery channel. Customers see your product on TikTok, then search Google and buy via Meta retargeting. Last-click gives Google or Meta the credit. Causality Engine traces the full causal chain and reveals TikTok's true role.
Should I cut TikTok spend based on last-click data?
Be very careful. Multiple Causality Engine customers have seen Google and Meta ROAS drop 2-4 weeks after cutting TikTok — because TikTok was creating the demand those channels captured. Test with causal data first.
Does this work for TikTok Shop?
Yes. If TikTok Shop purchases flow into your Shopify orders or GA4 data, Causality Engine includes them in the causal analysis alongside your standard ad campaigns.
How does the 40-day analysis window help with TikTok?
Beauty and fashion brands typically have 14-21 day consideration cycles. A customer discovers your product on TikTok, researches it over two weeks, then buys. A 7-day attribution window misses this entirely. Our 40-day window captures the full journey.
