Survey logic makes creating various paths for respondents easy by specifying what questions they will see next if they meet some conditions.

You can design the survey experience by adding a customized question flow and segmenting users based on their feedback.

In this article, you'll learn how to set up Survey logic in a Single answer selection and in a Dropdown list. If you want to set it up for different question types, visit one of the links below:

💡This feature is available for Email or Shareable link, Website or in-product, and Mobile surveys (starting from the SDK version 3.0.0).

How to add logic

Step 1. Once you've started creating your survey and added a Single answer selection or a Dropdown list, as well as the other survey questions, head over to the Logic tab of the question and click on + Add new logic.

In Mobile surveys, please go to Settings ➡️ Survey Experience and enable the Enhanced survey logic toggle to be able to set up Logic as described in this article:

Otherwise, by default, the Mobile survey will continue to have basic Logic settings available.

Step 2. Here, you'll see the If answer condition, letting you decide when to apply logic.

You can choose to apply logic if the response is or is not equal to one of the answer choices or when it has any value.

💡Let's take a look at what the above possibilities mean:

  • is - if you select just one possible answer here (eg. Answer 1), this logic will work only when your survey respondent selects Answer 1.

If you select Answer 1 or Answer 2, this logic will work for the respondents who select Answer 1 or Answer 2.

  • is not - if you select just one possible answer here (eg. Answer 1), this logic will work only when your survey respondent selects anything other than Answer 1.

If you select Answer 1 or Answer 2, this logic will work for the respondents who select anything other than Answer 1 and Answer 2, such as Answer 3.

  • has any value - this logic will work regardless of what answer the respondent chooses; for a non-mandatory dropdown list, this logic will work both when a respondent chooses any of the possible answers or skips the question without providing any answer.

Step 3. For this example, let's choose is.

What you'll see as the next step is the possibility of selecting one or several options of the possible answers.

Choose the desired option(s) simply by clicking on the answer choices.

📌 Any answer option not selected in the If answer condition will direct the respondents to the next question.

Step 4. Now, you can decide what question the respondent should see next.

In the then option, choose the next step, whether it's another question or the end of the survey.

Here, the respondent will be directed to the next step you choose if their answer to this question is either Answer 1 or Answer 2.

If they select any of the other possibilities, this logic will not be applied to them.

📌 It's not possible to use Survey logic to direct the respondent to a previous question. To select the next step in the survey's path, it needs to be placed after the question in which you're currently setting up logic.

Step 5. You successfully added a new logic to your survey 🚀.

If you'd like to add another one to the same question, click on + Add new logic again and repeat the above steps.

If you changed your mind and would rather delete the logic, simply click on the button.

Please note that if there is a conflict in your multiple logic settings, the survey behavior will be determined by the first true logic condition.

❗️Also, if you delete a question that is used in any logic settings in a survey, all the settings where it was used will be removed because they become invalid.

The same applies to the situation when you move a question above some other questions that have it in their logic settings - the logic becomes invalid and that's why we remove all logic settings that included the re-ordered question.

📌 Please remember that if you enable Enhanced Logic in your Mobile surveys, the survey will only appear in your mobile application if the SDK version you're using is not older than 3.0.0.

Best practices

Set up survey logic separately for each question in your survey

Without survey logic, the questions will be shown one after the other.

You can test the logic flow on the right side of the Create tab in the preview.
