Send conversion events from your tracker to source without limits on accounts or sources. Your ads platform can't optimize what it can't see. Conversion API sends event data — purchases, leads, registrations — directly from your tracker to the ad platform. Its algorithm receives a clear signal: who converts, at what cost, and from which audience segment. With this data, the platform optimizes ad delivery toward people most likely to convert. The result: cheaper clicks, more leads, and your budget stops burning on cold audiences.
