How to Turn Free Promotions into Long‑Term Customer Value with the Hook Model

1. Activity Goal

The "Earn Free Service, Full Refund" campaign by 58 Home Services aims to increase new‑user conversion and overall customer lifetime value (LTV) for online small‑home‑service sales such as cleaning, repair, and moving.

New‑user conversion is the first purchase that demonstrates product value, while customer lifetime value aggregates all economic benefits derived from a user over the entire relationship.

2. Activity Value

In the experience‑economy era, retaining customers and encouraging repeat purchases generate far more revenue than a single transaction; therefore, businesses should prioritize LTV over one‑off sales.

The diagram compares two coffee shops: the right‑hand shop lowers price to increase repeat purchases, achieving a higher total LTV (800 CNY) than the left‑hand shop (240 CNY).

3. Applying the Hook Model

The Hook model (Trigger → Action → Variable Reward → Investment) created by Nir Eyal explains how to make users addicted to a product.

Trigger (Trigger → Acquisition Phase)

Design concise, compelling copy—e.g., “Free Order”—to capture price‑sensitive users. Use strong verbs on buttons (“Grab”, “Rush”) and visual cues to reduce friction.

Action (Action → Conversion Phase)

Motivate users with clear benefits within 2‑5 seconds, using scarcity (“Only 100 slots”) and transparent processes to lower perceived effort. Simplify the flow so actions can be completed in two steps instead of five.

Variable Reward (Reward → Retention & Sharing Phase)

Provide unpredictable, varied rewards to sustain interest, following the marginal diminishing returns theory. Visualize progress, set a 27‑day task window with daily cash‑out options, and introduce mystery bonuses to keep users engaged.

Investment (Investment → Repurchase Phase)

Encourage users to invest time, money, and emotion, creating a sunk‑cost effect that raises the barrier to churn. Add share‑and‑invite tasks to turn passive behavior into active promotion, rewarding users for successful referrals.

4. User Lifecycle Stages

New User → First‑Order User → Repeat User → Loyal User → Dormant User

5. Measurement & Optimization

Set up data metrics for each funnel stage, monitor conversion rates, and iterate quickly to resolve bottlenecks, ensuring the promotion continuously drives new‑user acquisition and LTV growth.
