Call Deduplication or “De-Dupe” is a feature that prevents conversions and tracking URLs from being triggered multiple times because of the same caller calling back. When configuring tracking URLs or conversion groups on a Campaign, you can set a deduplication time frame. The campaign will then block repeat conversions or tracking URLs from being triggered for any particular caller within the time frame designated.
This is useful in situations where a customer has hung up the phone and redialed after being placed in a lengthy hold queue. You can dedupe calls for as little as one hour or for as long as a decade. Once the timer created by the first successful event expires the caller will be able to trigger another.
