How this is estimated: ad-blocker users block browser pixels entirely; Safari/iOS
visitors lose cross-session attribution after 7 days. We assume the overlaps and apply a ~85%
recovery rate for server-side delivery, in line with what CAPI adopters typically report.
Your untracked sales still happen — but your ad platforms can't optimize on them,
which quietly raises your cost per purchase.
