What is the difference between client-side pixels and server-side synchronization for ad tracking?

Client-side pixels depend on the visitor browser and can be blocked, delayed, or dropped, leading to severe data loss. Server-side synchronization sends event data directly from your server to ad platforms, bypassing those browser limitations. SEATEXT uses first-party server-side event buffering to ensure conversion signals reach your ad networks reliably. That gives you cleaner data for bidding algorithms and better retargeting audiences.
