Signal loss calculator
How much of your revenue an ad platform can't see. Compare your real orders or leads with the conversion events the platform received, not with the purchases it attributed to its ads. Runs in your browser; nothing is sent anywhere.
This is revenue the platform can't learn from or report, not revenue you lost. But the algorithm optimizes on what it sees, so a big gap usually means worse targeting and a reported ROAS lower than reality. As a rule of thumb, aim for 95%+ received on server-side setups.
Attribution gaps are normal. Signal gaps aren't.
Ad platforms only credit sales to their own ads, so their purchase numbers are always lower than your orders. That part isn't a problem. Events that never arrive, or arrive without IDs, are.
