Use Sub-Copy to Reinforce Quiz Simplicity & Process

context

Users may still be unsure about what to expect from the quiz. If they think it's complicated or time-consuming, they're less likely to start.

Why?

A short, reassuring sub-copy explaining how quick and easy the quiz is—like "Answer a few quick questions, get your perfect match in seconds"—removes doubts and encourages participation. Clear expectations make users more likely to engage.

Content
  • Your quiz completion rate is below 65% and bounce rate from quiz landing pages exceeds 50%
  • Analytics show users spending less than 10 seconds on quiz introduction pages before leaving
  • You have a product recommendation quiz but lack clear messaging about time commitment or complexity
  • Your store gets 1,000+ monthly visitors and uses quizzes as a primary conversion tool
  • You're on Shopify, Shopify Plus, or any platform that allows custom HTML/CSS for quiz implementations

Add reassuring sub-copy directly below your quiz headline to set clear expectations and reduce user hesitation.

  1. Position the sub-copy 16-24px below your main quiz headline, using 14-16px font size in a lighter color (60-70% opacity of your primary text)
  2. For Shopify stores: Navigate to your quiz page template or use a page builder like PageFly. Add a <p> tag with class quiz-subcopy below your headline
  3. Use this proven formula: Time commitment + Benefit + Simplicity. Examples: "3 quick questions, personalized results in 30 seconds" or "Answer 5 easy questions, discover your perfect product match instantly"
  4. Style for mobile: Ensure 14px minimum font size and center-align text. Test readability on devices with 375px width
  5. A/B test variations focusing on different time commitments (30 seconds vs 2 minutes) and benefit language (perfect match vs personalized recommendations)

<div class="quiz-intro">
<h2>Find Your Perfect Product</h2>
<p class="quiz-subcopy">Answer 4 quick questions, get personalized results in under 60 seconds</p>
<button class="quiz-start">Start Quiz</button>
</div>

Implementation time: 30-60 minutes including testing across devices.

  • Quiz start rate: Expect 15-25% improvement in users who begin the quiz after viewing the introduction
  • Quiz completion rate: Look for 8-15% increase in users who finish the entire quiz process
  • Time on quiz intro page: Average session duration should increase by 20-30 seconds
  • Overall conversion rate: Monitor 5-12% lift in quiz-to-purchase conversions within 3-4 weeks of implementation
  • AVOID: Vague language like "quick and easy" without specific time commitments. BEST PRACTICE: Use exact timeframes like "under 2 minutes" or "in 30 seconds"
  • AVOID: Making sub-copy too prominent or larger than 16px font size. BEST PRACTICE: Keep it subtle and supportive, not competing with your main headline
  • AVOID: Overpromising results with terms like "perfect" or "guaranteed match." BEST PRACTICE: Use "personalized recommendations" or "tailored suggestions"
  • AVOID: Placing sub-copy after the CTA button where users might miss it. BEST PRACTICE: Position it between headline and button for optimal visibility
