Allocate credit across awareness, exploration, trial initiation, activation, first charge, and renewal checkpoints, weighting by proximity and predicted influence. Penalize spammy frequency. Reward continuity that escorts users through friction. Keep it interpretable so marketers, finance, and product can debate and refine without mysticism obstructing accountability.
Fold expected tenure, plan mix, discounts, and churn risk into attribution weights. A channel driving discounted trials that cancel quickly should not outrank smaller volumes that mature into profitable annuals. Ground the math in observed transactions so proclaimed value aligns with deposits, not dashboards.
Use survival analysis to estimate time-to-churn and renewal likelihood by acquisition source and creative. Hazard curves reveal where retention marketing changes slope. This enables bids and budgets that prefer customers whose probability of staying rises with nurturing, rather than those predisposed to bail early.
