One of the most critical factors in your quiz's success is its length. If a quiz is too short, it lacks "Perceived Value"—the user doesn't feel the result is earned or accurate. If it is too long, "Quiz Fatigue" sets in, leading to high drop-off rates.
Based on our analysis of thousands of successful LeadQuizzes campaigns, here is the data-driven breakdown:
The Sweet Spot: 5 to 10 questions.
The Lead Gen Target: 6 to 8 questions (the "Magic Number").
The Time Window: 60 to 90 seconds total completion time.
Best Practices for Length Optimization
When launching a new quiz, start with 7 high-impact questions. This provides a solid baseline for your initial reports.
Don't ask irrelevant questions. Use Skip Logic to create a personalized path, ensuring every question the user sees is directly applicable to them.
Check your LeadQuizzes Drop-off Report. If you see a significant exit at question #9, it's a clear signal to shorten the flow.
Every click must feel like momentum. If a question doesn't help calculate the final result or qualify the lead, remove it.
A quiz with 8 well-written questions often has a higher completion rate than a quiz with 4 generic questions because the user feels they are receiving a more "tailored" diagnosis or recommendation.
