Fix Your Google Ads Attribution: Stop Overpaying for Clicks
Google Ads drives massive traffic for Shopify eCommerce brands but flawed attribution leads to overpayment for clicks that don’t generate real sales. Last-click models and cookie-based tracking can’t capture multi-touch journeys or cross-device sales.
Causality Engine leverages Bayesian causal inference to deliver accurate Google Ads attribution, helping you reduce wasted spend and improve campaign efficiency.
The Problem with Google Ads Attribution
Overcounting conversions due to last-click bias
Ignoring incremental impact and overlap with other channels
Misattributing organic or direct conversions to paid clicks
This results in inflated conversion numbers and suboptimal bidding strategies.
