2. Step 2: Identify the main goal

   The main goal is natural user growth through invitations, not ads or data analysis.

3. Final Answer:

   To encourage users to invite others, increasing growth -> Option D

4. Quick Check:

   Viral loop = user invitations for growth [OK]

Hint: Viral loops focus on user invitations to grow [OK]

Common Mistakes:

• Confusing viral loops with paid ads
• Thinking viral loops analyze data only
• Assuming viral loops are about design only

2. Which of the following is a correct step in designing a viral loop?

easy

A. Remove sharing options from the product

B. Ignore user feedback during the loop

C. Offer rewards to users who invite friends

D. Limit the number of invitations a user can send to zero

Solution

1. Step 1: Identify effective viral loop steps

   Offering rewards motivates users to invite others, making the loop effective.

2. Step 2: Eliminate incorrect options

   Ignoring feedback, removing sharing, or blocking invitations stop the loop from working.

3. Final Answer:

   Offer rewards to users who invite friends -> Option C

4. Quick Check:

   Rewards encourage sharing [OK]

Hint: Rewards boost user sharing in viral loops [OK]

Common Mistakes:

• Thinking ignoring feedback helps viral loops
• Believing removing sharing helps growth
• Assuming no invitations is effective

3. Consider this viral loop scenario: A user invites 3 friends, each friend invites 2 friends, and those friends invite 1 friend each. How many new users are added after these 3 invitation steps?

medium

A. 6

B. 15

C. 10

D. 9

Solution

1. Step 1: Calculate first invitation step

   User invites 3 friends, so 3 new users added.

2. Step 2: Calculate second and third steps

   Each of those 3 friends invites 2 friends: 3 x 2 = 6 new users.
   Each of those 6 friends invites 1 friend: 6 x 1 = 6 new users.

3. Step 3: Add all new users

   Total new users = 3 + 6 + 6 = 15 new users.

4. Final Answer:

   15 -> Option B

5. Quick Check:

   3 + 6 + 6 = 15 [OK]

Hint: Add each invitation step users carefully [OK]

Common Mistakes:

• Adding only first step users
• Multiplying instead of adding
• Ignoring last invitation step

4. A viral loop was designed but users are not sharing the product. Which of the following is the most likely error?

medium

A. The rewards are too small or unclear

B. The product has too many sharing options

C. Users are forced to invite too many friends

D. The product does not collect user emails

Solution

1. Step 1: Analyze why users don't share

   Users need clear and valuable rewards to motivate sharing.

2. Step 2: Evaluate other options

   Too many sharing options usually help; forcing invites can annoy users but is less common; email collection is unrelated to sharing motivation.

3. Final Answer:

   The rewards are too small or unclear -> Option A

4. Quick Check:

   Small rewards reduce sharing [OK]

Hint: Check if rewards motivate users to share [OK]

Common Mistakes:

• Blaming too many sharing options
• Assuming forced invites always work
• Confusing email collection with sharing

5. You want to design a viral loop that filters out inactive users automatically. Which approach best fits this goal?

hard

A. Reward only users whose invited friends become active

B. Allow unlimited invitations without tracking activity

C. Send rewards to all users regardless of friend activity

D. Remove rewards and rely on product quality only

Solution

1. Step 1: Understand filtering inactive users

   To filter inactive users, rewards should depend on friend activity, encouraging quality invites.

2. Step 2: Compare options

   Unlimited invites without tracking won't filter; rewarding all ignores activity; no rewards reduces motivation.

3. Final Answer:

   Reward only users whose invited friends become active -> Option A

4. Quick Check:

   Reward based on friend activity filters inactive users [OK]

Hint: Tie rewards to friend activity to filter inactive users [OK]

Common Mistakes:

• Ignoring friend activity in rewards
• Allowing unlimited invites without checks
• Removing rewards reduces motivation
