Aggregated Event Measurement (AEM)
Meta's iOS 14+ privacy measurement protocol
In Simple Words (Zero Jargon):
Meta's iOS 14+ privacy measurement protocol
Why It Is Critical
AEM allows advertisers to configure up to 8 conversion events per domain ranked by priority, in response to Apple ATT opt-outs. When an iOS user converts, Meta records the highest-priority event that fired. If Purchase is not prioritized first, conversion data will be lost.
What You Get: Partial recovery of iOS conversion signal - and accurate campaign reporting for the significant portion of Meta’s audience that uses iOS devices.
