Estimate how many Meta conversions you are losing to ATT opt-outs — and what a server-side CAPI rebuild is realistically worth to you per month.

How this is modelled. Opt-in users are tracked normally. Opt-outs lose deterministic attribution; SKAN aggregated reporting recovers about 30% of those signals at most. Non-iOS traffic is unaffected.
CAPI + first-party event matching typically claws back 70–90% of the iOS signal that ATT removes, by sending hashed user data server-to-server with a high event-match-quality.
