Server-side attribution, start to finish

How we get deterministic conversion signal back after iOS and cookie loss — without rebuilding the stack.

Browser-side pixels now miss 30–60% of conversions on iOS. If you're optimizing paid on that signal, you're flying blind. The fix is server-side: fire conversion events from your backend to each platform's API — Meta CAPI, TikTok Events API, LinkedIn Conversions API.

The pattern: capture the event once, server-side, then fan it out. That single source of truth survives browser privacy changes and gives every platform the same signal to train on.

The trap is double-counting — if you leave the client-side pixel on too, you'll report twice the conversions. Turn the pixel to a backup, make the server the system of record, and reconcile weekly. Done right, attribution gets sharper, not weaker, after iOS.
