Conversion Deduplication: Prevent Double Counting

Duplicate conversions occur when the same business event is reported more than once, often because browser and server events both fire or retries create repeated records.

The core idea

Use a stable event or transaction ID, make receivers idempotent and define which system owns the canonical conversion.

What matters in practice

Test refreshes, back-button behavior, webhook retries and payment-provider callbacks.

Decision rule

Accurate attribution begins with an accurate conversion count.

Tracking principle: Define the business outcome first, then choose the measurement method and software. A sophisticated dashboard cannot repair unclear event definitions or inconsistent campaign naming.
