Shorter Is Always Better

The #1 mistake: surveys that are too long. Every extra question increases dropoff and decreases response quality. People get tired. They start clicking randomly just to finish. Your data becomes garbage. The best surveys are 5-10 questions and take 2-4 minutes. Anything longer needs a really good reason.

📏 Survey Length Guidelines

✓5-10 questions: Ideal. High completion, good quality data.
⚠️10-15 questions: Acceptable if necessary. Watch dropoff rates.
✗15+ questions: Too long. Split into multiple surveys or cut questions.

Question Types & When to Use Them

📊 Multiple Choice

Best for: Predefined options, easy to analyze.

Example: "Which feature would you use most? A) X B) Y C) Z"

⭐ Rating Scale

Best for: Measuring intensity (satisfaction, likelihood, importance).

Example: "How likely to recommend? 1-10"

✍️ Open Text

Best for: Collecting quotes, unexpected insights. Use sparingly.

Example: "What\'s your biggest frustration with [product]?"

☑️ Checkboxes

Best for: Multiple selections allowed.

Example: "Select all tools you use: □ Slack □ Zoom □ Email"

Don\'t Ask What You Can Track

Bad: "How often do you use the product?" (Track this in analytics!)
Good: "Why do you use the product that often?" (Can\'t track motivation.)

Key Takeaways

  • •Keep surveys to 5-10 questions. Every extra question increases dropoff and reduces data quality.
  • •Structure: Opening context → Screener → Core questions → Optional demographics → Thank you.
  • •Use multiple choice for analysis, rating scales for intensity, open text sparingly for insights.
  • •Never ask what you can track in analytics. Surveys are for understanding "why," not "how much."
