Survey logics is an effective tool that can shape your survey based on respondents’ answers, ensuring they only encounter questions relevant to their experiences. By incorporating various logic rules, you can provide a seamless and engaging survey experience for your respondents, ultimately leading to higher completion rates and more accurate data. Using the right survey language, it is possible to further enhance the clarity and effectiveness of your surveys.

The main types of survey logic are:

  • skip logic,
  • branching logic, and
  • piping logic.

Let’s explore each of these techniques to grasp the fundamentals of survey logic in general.

Skip logic

Skip logic, also known as conditional branching, allows you to design surveys in a way that enables respondents to skip over irrelevant questions and proceed to the next relevant section of the survey. This technique helps improve survey efficiency by ensuring that respondents only answer questions applicable to their situation.


If you ask respondents whether or not they have ever traveled to Europe and they answer “No,” with skip logic in place, the subsequent questions about details regarding European traveling experience can be skipped.

Branching logic

Branching logic is another powerful technique that directs respondents to relevant follow-up questions based on their answers to a multiple-choice question or other types of questions. This personalization ensures that respondents only view questions pertinent to their prior responses, which can serve as a motivator to answer your survey. As a result, you will receive reliable feedback and accurate data for subsequent analysis. Implementing branching logic also creates a more engaging survey experience and increases the likelihood of survey completion.


You have been assigned to conduct a survey for an HR agency. The opening question might start “Are you an employer or an employee?”. Depending on the answer, branching logic could direct respondents to an entirely different set of questions tailored either to employers or employees.

Piping logic

Piping logic is a technique that incorporates one answer from a previous question into subsequent questions, providing a more personalized interaction for respondents. This technique can be particularly useful when asking follow-up questions based on previous answers, creating a sense of continuity and relevance throughout the survey.

The use of piping logic helps you create a dynamic set of questions that adapt on the fly, resulting in richer data collection and deeper insights without extending the overall length of your survey.


When a respondent indicates in a question regarding color preference that their favorite color is blue, a later question will use this information to ask this way: “Why do you prefer blue over other colors?”

Once you decide to add survey logic in your surveys, you will see that it is not difficult at all. Let’s take Survio as a well-known survey software to set an example. All you need to do is click on the question to which the rule is to be applied, select “Logic” and choose the appropriate action. Feel free to broaden your horizons by other practical examples on survey logic.

Implementing survey logic rules

Now that you are familiar with the basics of survey logic, it is time to learn how to implement these rules in your survey. Implementing survey logic rules involves setting up actions and criteria for multi-question and single-question branching, which can be combined using AND/OR logic. Let’s take a closer look at the different ways to implement survey logic rules.

Multi-question branching

Multi-question branching is a type of branching logic that directs respondents to different sets of questions based on their answers to prior questions. This technique is particularly useful in the following cases, when you want to:

  • create a highly tailored survey experience for respondents with different backgrounds or interests,
  • gather specific information from different groups of respondents,
  • save time by skipping irrelevant questions for certain respondents.

By using multi-question branching, you can ensure that each respondent receives a survey that is relevant to their needs and interests.

Single-question branching

Single-question branching is another type of branching logic that determines the next question shown based on a respondent’s answer. This technique simplifies the feedback process for respondents by allowing them to seamlessly move on to the next relevant question.

When implementing multi-question or single-question branching, it is important to create relevant and necessary logic rules to avoid overcomplicating your survey. Effective use of multi-question branching increases survey relevance, reduces survey fatigue, and improves data accuracy.

Combining AND/OR logic

Combining AND/OR logic allows for more complex survey logic rules and conditions, enabling you to create highly customized survey journey for a wide range of respondents.

  • The AND operator is used to combine multiple conditions, i.e. all conditions must be true for the overall condition to be true.
  • The OR operator, on the other hand, requires only one condition to be true for the overall condition to be true.

Customizing your survey with logic

Customizing your surveys by adding logic to questions, managing multiple rules, and testing and refining the rules’ framework is essential for creating a smooth, highly engaging, and relevant interaction for your respondents.

Let’s delve deeper into the process of tailoring your survey with logic and custom data, and explore some best practices for each step.

Adding logic to questions

Adding logic to questions is the next step in customizing your survey. While various online survey platforms have differenct user interfaces for creating specific conditions within the survey flow, the overall process is generally the same.

  1. Select the desired question and look for the “Logic” icon in its settings.
  2. Click this icon to add logic to the question.
  3. Configure the necessary actions for each question and ensure that they remain relevant to each respondent’s answer.

When adding logic to questions, it is advisable to strike a balance between creating a personalized survey experience and avoiding unnecessary complexity.

Managing multiple rules

Managing multiple rules is an essential skill when applying logic to your surveys. To create and organize multiple rules, you will need to consider their order, making sure that the survey unfolds logically and smoothly.

Testing and refining logic

Testing and refining logic is inevitable, as it ensures that your survey logic works correctly and provides a seamless interaction for your respondents. To test and refine your logic, consider checking your survey in a preview mode or running it with test respondents, making any necessary adjustments based on their feedback.

Additionally, it is recommended that youproperly document your logic for the purpose of tracking changes. This will make the entire survey logic frame accurate, efficient, and effective.
