How 30% of conversion data hits a wall, and how Server-Side bridges the gap.
The Leak (Left): The browser attempts to send a signal directly to Meta/Google. However, ~30% of these signals are destroyed by Privacy Blockers (Ad Blockers, Apple's App Tracking Transparency, Safari ITP, Cookie choices). The algorithm never learns about the purchase.
The Fix (Right): Data is sent to a Server you own. Because it's a first-party server, blockers ignore it. The Server then securely forwards 100% of the data directly to the Ad Platform's API, bypassing browser restrictions entirely and improving ROAS.
