Meta Ads Management Term

Aggregated Event Measurement (AEM)

Aggregated Event Measurement is Meta's protocol for measuring web events from iOS 14+ users who opt out of tracking. It limits you to 8 prioritized conversion events per domain and uses modeled data to fill attribution gaps.

Example in Practice

"We configured our 8 AEM events with Purchase as top priority, followed by InitiateCheckout, AddToCart, and ViewContent for our ecommerce store."

Conversions API (CAPI)

The Conversions API is a server-side tracking solution that sends conversion data directly from your server to Meta. Unlike the Pixel (browser-based), CAPI isn't affected by ad blockers, iOS privacy restrictions, or cookie limitations, providing more accurate attribution.
