Example

Your SaaS app ran a Meta campaign promoting free trial sign-ups. In the first week, 842 registrations were completed.

Campaign	Spend	Registrations	Cost per Registration
Free Trial - Broad	$2,400	512	$4.69
Free Trial - Lookalike	$1,800	330	$5.45

How It Works

Meta tracks the CompleteRegistration event fired when a user finishes your sign-up flow. Attribution follows your account’s attribution window settings (typically 7-day click, 1-day view). Registrations from both Facebook and Instagram placements are combined.
