Data Deduplication Before After
Project Challenge

The client noticed their ad reports showed 300 purchases while their Shopify store only had 100 actual orders. This 3x data inflation was causing the ad algorithm to overspend on the wrong audiences and provided a false sense of high ROAS.

Our Solution
  • 01
    Identifying the Leak

    Using GTM Debug Mode, we found that the purchase event was firing from the Browser Pixel, the Server API, and a hardcoded Shopify integration simultaneously.

  • 02
    Event ID Implementation

    We configured a unique Event ID variable in GTM that attaches to every transaction. This allows Facebook and Google to recognize identical events and count them as one.

  • 03
    Clean Up & Verification

    We removed the redundant hardcoded pixels and verified the fix using the Facebook Test Events tool, confirming that "Deduplicated" status was active.

The Results

Data inflation was completely eliminated. The client now sees 100% accurate purchase data in their Ads Manager, allowing for true ROAS calculation and confident scaling.
