How to add logic to your online survey?

Not every respondent needs to see the same questions.

With Logic in Porsline, you can adapt the survey path according to previous answers and create a more relevant experience for each participant.

In this video, we use a simple product survey to show how conditional paths work and how different answers can lead respondents to different follow-up questions.

Create More Relevant Survey Paths

Imagine that your business offers two products.

Customers who select the first product should see questions about their experience with that product. Customers who select the second one should follow a different path.

Without Logic, both groups may have to answer questions that do not apply to them.

With conditional paths, you can keep the survey focused while still bringing respondents back to shared questions when needed.

This makes Logic especially useful when one online survey needs to serve several audiences, products, departments or respondent groups.

What You Will See in This Video

The video introduces the main ideas behind Logic in Porsline, including:

• Connecting an answer to a specific follow-up question
• Creating different paths within one survey
• Adding or removing conditions
• Combining conditions with AND and OR
• Identifying questions that already contain Logic
• Previewing response paths before activation

The purpose of this video is to help you understand how the feature behaves before you apply it to your own survey.

When Survey Logic Is Useful

Logic can support many survey and form scenarios.

For example, market and product research teams may need to show different questions depending on the product a participant uses, the audience segment they belong to or their previous experience with a service.

Using Logic within your market research surveys helps you keep each question path relevant while collecting the different types of information your study requires.

You may use it to:

• Ask product-specific follow-up questions
• Show different sections to different employee groups
• Screen respondents before a research section
• Direct qualified leads to relevant questions
• Create different paths for customers with different experiences

The most effective use of Logic is usually the simplest one: hide questions that are not relevant and keep each respondent on a clear path.

For surveys where respondents can select several answers, watch our video on logic in multiple-choice questions.

Preview Every Path Before Sharing

Conditional surveys can contain several possible routes.

Before activating your survey, use Preview to move through each route and confirm that respondents reach the intended questions.

Pay particular attention to:

• Less common answers
• Combined AND and OR conditions
• Questions shared by several paths
• The destination at the end of each route

Testing helps you identify incomplete or conflicting paths before respondents begin submitting answers.

Explore Logic in Your Porsline Survey

Logic gives you more control over the questions each respondent sees, without requiring separate surveys for every audience.

Start with one clear condition, preview the result and add more complex paths only when your survey genuinely requires them.
