What causes signal loss between my website analytics and ad platforms?

Signal loss typically occurs because client-side tracking scripts fail due to ad blockers, strict browser privacy rules like Apple Safari ITP, or network timeouts. When key data points drop between your site and analytics tools, reporting shows severe discrepancies and ad algorithms end up optimizing blindly. Switching to first-party server-side synchronization resolves this by buffering events securely and ensuring consistent feedback loops for your bidding models.
