Referral Program Mechanics

📖 Scenario: You work for a company launching a new referral program to encourage customers to invite friends. The program rewards both the referrer and the friend with discounts.Your task is to build a simple step-by-step plan that outlines how the referral program works, including tracking referrals, setting reward thresholds, and finalizing the reward distribution.

🎯 Goal: Create a clear, structured outline of the referral program mechanics that can be used by the marketing team to implement and explain the program.

📋 What You'll Learn

Define the initial data structure to hold customer referrals

Add a configuration variable for the minimum number of referrals needed for a reward

Apply the core logic to identify customers who qualify for rewards

💼 Career

Understanding referral program mechanics helps marketing professionals design effective campaigns and track their success.

1

DATA SETUP: Create the referral data structure

Create a dictionary called referrals with these exact entries: 'Alice': 3, 'Bob': 1, 'Charlie': 5, representing the number of friends each customer referred.

Digital Marketing

# Create the referrals dictionary with exact entries
# Your code here

Hint

Use a Python dictionary with customer names as keys and referral counts as values.

2

CONFIGURATION: Set the referral reward threshold

Create a variable called reward_threshold and set it to 3, representing the minimum referrals needed to earn a reward.

Digital Marketing

referrals = {'Alice': 3, 'Bob': 1, 'Charlie': 5}
# Set the reward threshold to 3
# Your code here

Hint

This variable helps decide who qualifies for rewards.

3

CORE LOGIC: Identify customers who qualify for rewards

Create a list called qualified_customers that includes the names of customers from referrals who have referred at least reward_threshold friends. Use a for loop with variables customer and count to iterate over referrals.items().

Digital Marketing

referrals = {'Alice': 3, 'Bob': 1, 'Charlie': 5}
reward_threshold = 3
# Create the qualified_customers list using a for loop
# Your code here

Hint

Use a for loop to check each customer's referral count against the threshold.

4

COMPLETION: Define the reward assignment

Create a dictionary called rewards where each key is a customer from qualified_customers and the value is the string 'Discount Voucher' to represent the reward assigned.

Digital Marketing

referrals = {'Alice': 3, 'Bob': 1, 'Charlie': 5}
reward_threshold = 3
qualified_customers = []
for customer, count in referrals.items():
    if count >= reward_threshold:
        qualified_customers.append(customer)
# Assign 'Discount Voucher' reward to each qualified customer
# Your code here

Hint

Use a dictionary comprehension to assign rewards to qualified customers.

Practice

1. What is the main purpose of a referral program in digital marketing?

easy

A. To limit the number of customers

B. To increase the price of products

C. To encourage existing customers to bring in new customers

D. To reduce the quality of services

Solution

1. Step 1: Understand referral program goal

   Referral programs aim to grow customer base by using existing customers as promoters.

2. Step 2: Identify correct purpose

   The main goal is to encourage current customers to invite others, increasing new customers.

3. Final Answer:

   To encourage existing customers to bring in new customers -> Option C

4. Quick Check:

   Referral programs = customer growth [OK]

Hint: Referral programs reward sharing to grow customers fast [OK]

Common Mistakes:

• Thinking referral programs increase prices
• Believing referral programs reduce service quality
• Assuming referral programs limit customers

2. Which of the following is a common reward given in referral programs?

easy

A. Free product or discount

B. Increased subscription fees

C. Delayed delivery times

D. Reduced customer support

Solution

1. Step 1: Identify typical referral rewards

   Referral programs usually offer incentives like discounts or free products to motivate sharing.

2. Step 2: Match reward type

   Free products or discounts are positive rewards, unlike fees or delays which discourage customers.

3. Final Answer:

   Free product or discount -> Option A

4. Quick Check:

   Referral rewards = discounts or freebies [OK]

Hint: Rewards are positive incentives like discounts, not penalties [OK]

Common Mistakes:

• Confusing rewards with penalties
• Thinking referral rewards increase costs
• Assuming rewards reduce service quality

3. Consider this referral program rule: "For every 3 friends referred, the referrer gets a $10 credit." If a customer refers 7 friends, how much credit do they earn?

medium

A. $10

B. $30

C. $70

D. $20

Solution

1. Step 1: Calculate full groups of 3 referrals

   7 friends referred means 2 full groups of 3 (since 3*2=6), with 1 leftover.

2. Step 2: Multiply groups by credit

   2 groups x $10 credit = $20 total credit earned.

3. Final Answer:

   $20 -> Option D

4. Quick Check:

   Floor(7/3) x 10 = 20 [OK]

Hint: Divide referrals by 3, multiply by $10 credit [OK]

Common Mistakes:

• Multiplying total referrals by $10 directly
• Ignoring leftover referrals
• Adding credit for incomplete groups

4. A referral program states: "Referrer and referee both get a 15% discount." A user tries to apply the discount twice on the same purchase and it fails. What is the likely issue?

medium

A. The program only allows one discount per purchase

B. The discount percentage is too high

C. The referee is not eligible for any discount

D. The referrer must pay extra fees

Solution

1. Step 1: Understand discount application rules

   Most referral programs limit discounts to one per purchase to avoid stacking.

2. Step 2: Identify why applying twice fails

   Trying to apply the same discount twice likely violates the one-discount-per-purchase rule.

3. Final Answer:

   The program only allows one discount per purchase -> Option A

4. Quick Check:

   One discount per purchase rule = failure on double apply [OK]

Hint: Check if multiple discounts are allowed per purchase [OK]

Common Mistakes:

• Assuming referee gets no discount
• Thinking discount percentage causes failure
• Believing referrer pays extra fees

5. A company wants to design a referral program where the referrer earns $5 for each new customer, but only if the new customer spends at least $50. Which of these is the best way to ensure fairness and success?

hard

A. Give $5 to referrers immediately after referral regardless of purchase

B. Track new customer purchases and only reward referrers when spending meets $50

C. Reward referrers only after 10 referrals, ignoring purchase amounts

D. Offer rewards only to new customers, not referrers

Solution

1. Step 1: Understand program goal

   The company wants to reward referrers only if new customers spend $50 or more.

2. Step 2: Choose method ensuring fairness

   Tracking purchases and rewarding only when spending meets $50 ensures fairness and avoids wasted rewards.

3. Final Answer:

   Track new customer purchases and only reward referrers when spending meets $50 -> Option B

4. Quick Check:

   Purchase tracking ensures fair rewards [OK]

Hint: Reward only after verifying new customer spends $50+ [OK]

Common Mistakes:

• Rewarding referrers without purchase verification
• Ignoring purchase amount conditions
• Rewarding only new customers, not referrers
