Sorger categorizes marketing analytics into descriptive (what happened), predictive (what will happen), and prescriptive (what to do about it). Within these, several strategic models stand out: Pro Tip: Search your university library’s website for
1. Customer Lifetime Value (CLV) Model
CLV is the bedrock of customer-centric strategy. Sorger’s model moves beyond simple transaction value to incorporate retention rates, discount rates, and future contribution margins. The formula is often expressed as:
[
CLV = \sum_t=1^n \frac(Revenue_t - Cost_t) \times Retention_t(1 + d)^t
]
Where (d) is the discount rate. Strategically, CLV helps firms decide how much to spend on customer acquisition (CAC) – typically maintaining a CLV:CAC ratio of 3:1.
2. Market Response (or Attribution) Models
Attribution remains a challenge in multi-channel marketing. Sorger discusses linear, time-decay, and Shapley value models to assign credit to touchpoints. For instance, a logistic regression model might predict purchase probability as:
[
P(Purchase) = \frac11 + e^-(a + b_1 X_1 + b_2 X_2 + ... + b_k X_k)
]
Where (X_i) are marketing activities (email, social, search). This allows marketers to shift budget toward high-ROI channels. predictive (what will happen)
3. RFM Segmentation (Recency, Frequency, Monetary)
A simple yet powerful model, RFM ranks customers based on how recently they purchased, how often, and how much they spent. Sorger positions RFM as a starting point for personalization – e.g., targeting “champions” (high R, F, M) with loyalty offers and “at-risk” (low R, high F, M) with win-back campaigns.
