Picking the wrong model or lookback window

Multi-touch: Combines pixel data with post-purchase survey responses to weight credit based on what influenced the sale.
Trusting ad platforms to self-report
Ad networks claim as much credit as possible. They use broad view-through windows and count impressions as touches. Two platforms will both claim the same conversion, and there is no way to reconcile the numbers from inside their dashboards.
Centralizing data outside the ad platforms is the fix. ThoughtMetric pulls conversion data directly from your store and matches it against ad platform data, so each channel gets credit once and the totals reconcile to actual revenue.
Skipping post-purchase surveys
A post-purchase survey on the order confirmation page closes the gap. A simple "How did you hear about us?" question surfaces channels that digital tracking cannot see. ThoughtMetric runs post-purchase surveys natively and ties responses back to the same customer record as paid attribution data.
