Ad Allocation to High-Intent Users Only
Scenario
A product manager proposes allocating all ad impressions to the "high-intent" user segment (users predicted to have a high probability of clicking/converting), and serving no ads to other users.
Assumptions (for clarity):
- You operate a two-sided ads marketplace with finite ad inventory per day.
- Users can be segmented by predicted intent (e.g., high vs. non-high).
- Platform objectives include short-term revenue, user experience, and long-term growth.
Question
If we serve ads only to the high-intent segment, what are the main pros and cons in terms of:
- Revenue (short-term yield and total revenue)
- User experience (fatigue vs. relevance)
- Long-term growth (market size, learning rate, and ecosystem health)
Hints: Consider short-term yield, user fatigue, market size, and model learning rate.
