CAPI dedup or double counting. Why are events inflated?
When both the browser pixel and CAPI send the same conversion event without a deduplication mechanism, Meta counts the event twice. This inflates reported conversions and feeds the algorithm incorrect signal.
What this means
When both the browser pixel and CAPI send the same conversion event without a deduplication mechanism, Meta counts the event twice.
Quick steps
- Check Events Manager > Deduplication Diagnostics section
- Server events matched with browser should be above 80%
- Check event log for same event appearing twice
- Compare All Conversions to CRM order count (gap above 50% is unusual)
- Check for multiple pixel IDs or integration apps sending events
