Survey Logic & Branching

Make your surveys smarter by showing or hiding questions based on respondent answers. Logic helps create personalized experiences and collect more relevant data.

Types of Logic

Display Logic

Show or hide a question based on previous answers.

Example: Only show “Which features do you use?” if the respondent answered “Yes” to “Do you use our product?”

Skip Logic

Jump respondents to a different page or question based on their answer.

Example: If respondent selects “No experience,” skip to the end of the technical questions section.

Page Branching

Direct respondents to different survey paths based on their responses.

Example: Route customers vs. prospects to different sets of questions.

Setting Up Display Logic

1. Click on the question you want to control
2. Go to the Logic tab in the question settings
3. Click Add Display Logic
4. Set your condition:
   • Select the source question
   • Choose the operator (equals, contains, is greater than, etc.)
   • Select or enter the value
5. Save your logic

Logic Operators

• Is / Is not - Exact match
• Contains / Does not contain - Partial match
• Is greater than / Is less than - Numeric comparisons
• Is answered / Is not answered - Response presence

Multiple Conditions

Combine conditions with AND/OR:

• AND - All conditions must be true
• OR - Any condition can be true

Example: Show question if (Age > 18) AND (Country = USA)

Setting Up Skip Logic

1. Select the question with the triggering answer
2. Go to Logic tab
3. Click Add Skip Logic
4. For each answer option, set where to skip:
   • Specific question
   • Specific page
   • End of survey
5. Save

Page Branching

For complex surveys, set up page-level routing:

1. Go to page settings
2. Click Page Branching
3. Set conditions for which page comes next
4. Create multiple branches for different paths

Advanced Logic Features

Question Randomization

Randomize the order questions appear to reduce order bias.

1. Select questions to randomize
2. Enable Randomize Questions in settings
3. Optionally set questions to always appear first/last

Block Randomization

Randomize groups of questions while keeping related questions together.

Custom Variables

Create variables to track complex conditions across multiple questions.

1. Go to Survey Settings > Custom Variables
2. Define variable name and logic
3. Use variable in display logic conditions

Logic Best Practices

Keep It Simple

• Start with basic logic, add complexity as needed
• Test thoroughly after adding logic
• Document your logic flow

User Experience

• Don’t create confusing jumps
• Ensure all paths lead to completion
• Preview all possible paths

Data Quality

• Ensure required questions are always shown
• Don’t create impossible paths
• Test edge cases

Testing Your Logic

1. Preview Mode - Walk through all possible paths
2. Test Responses - Submit test responses for each scenario
3. Logic Map - Review your survey’s logic flow visually

Common Use Cases

Screening Questions

Filter out unqualified respondents early.

Q: Are you 18 or older?
- Yes → Continue
- No → Skip to End (disqualified message)

Product-Specific Questions

Only show relevant product questions.

Q: Which product do you own?
- Product A → Show Product A questions
- Product B → Show Product B questions
- None → Skip to general questions

Satisfaction Follow-up

Dive deeper based on satisfaction level.

Q: How satisfied are you? (1-10)
- 1-6 → Show "What can we improve?"
- 7-8 → Show "What did you like?"
- 9-10 → Show "Would you recommend us?"

Troubleshooting

Question not showing:

• Check logic conditions are correct
• Verify source question is earlier in survey
• Test with different answer combinations

Infinite loops:

• Review skip logic doesn’t create circles
• Ensure end conditions are reachable

Missing data:

• Skipped questions won’t have responses
• Account for this in your analysis
