Survey Design Best Practices

Highlight's Survey Blueprints, designed by product research experts, follow these best practices to improve your data quality, boost response rates, and make your insights more reliable.

Clarify your Research Objectives

Before you write a single question, ask yourself: “What must I learn from this survey?"

A focused objective helps you:

• Choose only the most relevant questions
• Avoid survey bloat
• Analyze your results more easily

Be Mindful of Survey Length

There’s lots of evidence that long surveys lead to lower completion rates, dropoff increasingly sharply after around 10 minutes.

Surveys longer than 10 minutes often lead to:

• ❌ Lower completion rates
• ❌ Respondent fatigue
• ❌ Rushed or low-quality answers

Most participants are happy to share thoughtful feedback— up to a point. Keeping your survey concise shows respect for their time and ensures more reliable results.

Rule of thumb:
5–7 minutes (or 15-20 questions) is ideal. Cap at 10 minutes (30 questions) when possible.

Ask Only What You’ll Use

Every question should tie directly back to your research objectives. If you’re unsure what you’ll do with the data from a question, consider removing it.

Questions to ask yourself:

• “Will I actually use this data to make a decision?”
• “Is this nice to know or need to know?”

Make It Easy to Answer

Help respondents move through your survey smoothly, keeping in mind many participants respond on a mobile device:

• Use plain language and simple, short questions
• Avoid double-barreled questions (e.g., “How satisfied are you with our product and service?”)
• Group similar topics together
• Limit open-ended questions

Designing a great survey isn’t just about asking the right questions—it’s about creating an experience that’s clear, focused, and respectful of your participants’ time.
