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.
