Instead of measuring surface engagement, it tracks how a partner's traffic moves through real buying actions. Signals like repeat purchases, cross-account adoption, and time-to-first-dollar reveal true value. Behavioral flow logs replace traditional dashboards, mapping how leads evolve after each partnership touchpoint. High-performing partners show shorter conversion loops and stronger downstream revenue lift across channels. Outliers are surfaced when engagement looks small but lifetime value spikes unexpectedly. This shifts optimization toward partnerships that quietly compound rather than simply attract attention.
