Surveys with Skip Logic, Branch Logic, Conditional Logic,Question routing

Apr 23, 2026 · 2 mins read

Skip logic surveys, done right, can increase your survey completion rates by as much as 375%. This page covers what skip logic is, how it compares to a regular survey flow, and how to set one up.

What is Skip Logic?

Skip logic decides which question shows next based on how the respondent answered the current one. It creates a customized path through the survey that changes with each respondent's answers. This feature is also known as "conditional branching," "conditional logic," "branch logic," or "jump logic."

Regular Survey Flow Vs. Skip Logic

In a typical survey, questions appear one after another. The order is the same for every respondent, though you can change it. Skip logic adds a condition to that order: you specify which question comes next based on how the previous one was answered. Skip logic allows you to move from static surveys to more user-friendly surveys. Because of the customizations, it also makes the survey easier to complete.

Skip logic surveys cut down the time it takes to finish a survey. Not everyone needs to answer every question, so skip logic can be the difference between a high response rate and a low one. It can also go too far: if too many people skip important questions, the results become unreliable. That risk applies to normal surveys as well as skip logic surveys.

Here is an example of skip logic survey. Try answering 'no' for the first time and then 'yes' the second time.

Various forms of Skip Logic

Skip logic is a common feature when building survey questionnaires, but the different types of skip logic are less widely known.

Conditional branching: It is used when a condition must be fulfilled when filling out the survey. The logic rules are applied during the questionnaire design process. It allows respondents to skip from one question to the next without having to see irrelevant questions.
Unconditional branching: This form of logic is typically used as a default logic. For example, regardless of their responses, all respondents would see a "Next Question" if not answered.
Close or End: The system will direct respondents to the survey's close or thank you page, and the response will be identified as a completion.
Chain multiple surveys: Use this to link multiple surveys in the same survey. You can set 'redirect on submit' to open the next survey. The whole experience is dynamic, and the respondents would be unaware that they have been transferred to a new survey. This is primarily used by market researchers while distributing surveys through Survey panel.

What are the advantages of using Skip Logic?

Online forms and surveys, including multiple-choice questions and single-row rating scale questions, need to capture respondents' answers and feedback accurately. Skip logic helps with this in several ways:

Limits the number of questions to be answered in your online surveys.
Excludes questions that will add no advantage to your desired results.
It makes the online surveys much quicker to answer for respondents.
Can help achieve greater and better completion rates.
Collects relevant questions and results for more accurate analysis.

Skip Logic in BlockSurvey

BlockSurvey is an online survey tool focused on data privacy and security. It is simple and effective for creating surveys of any kind, whether for schoolwork and students, personal use, or business.

That leaves the main question: does BlockSurvey support Skip Logic?

Yes. BlockSurvey supports Skip logic. As covered above, Skip Logic lets you create your own dynamic surveys that change what the respondent sees and what happens based on their response.

You can create various effects and actions triggered by different survey responses and survey options. Skip logic lets a respondent jump to a given question based on the answers given.

Skip logic surveys make a survey feel more like a discussion or conversation. They give you control over which questions get asked based on earlier answers, which makes the survey easier to follow for the customers using it.

Now that you know we support Skip Logic, how about giving it a try for yourself? You can head to the BlockSurvey website and create a skip logic survey. Our skip logic survey template helps you get started quickly.

Surveys with Skip Logic, Branch Logic, Conditional Logic,Question routing FAQ

What is skip logic in a survey?

Skip logic is a survey feature, also known as conditional branching, branch logic, or jump logic, that adjusts which question is shown next based on how a respondent answered the current question. Instead of every respondent seeing every question, skip logic routes each person only to questions relevant to them, which shortens completion time and keeps irrelevant questions out of their path.

What is an example of skip logic?

A common example is conditional branching: if a respondent's answer meets a specific condition, the survey jumps them past questions that don't apply and takes them straight to the next relevant question or section. BlockSurvey also supports routing a respondent directly to a completion or thank-you page once their answer marks the survey as done for them, rather than continuing through the remaining questions.

What is a skip pattern in a survey?

A skip pattern is the set of routing rules that decides which question a respondent sees next based on an earlier answer. In BlockSurvey, skip patterns are built from conditional branching, which routes respondents only when specific answer conditions are met, and unconditional branching, which moves every respondent through the same default sequence regardless of their answers.

How does skip logic work in a survey?

Skip logic works by attaching a rule to a question's answer options: when a respondent picks a given answer, the survey routes them to a designated next question, section, or the survey's end instead of the default next question. BlockSurvey builds this routing from conditional branching, unconditional branching, and a close-or-end option that sends qualifying respondents straight to a completion page.

What is the difference between skip logic and branching logic in a survey?

In BlockSurvey, skip logic and branching logic refer to the same routing capability: the page uses skip logic, conditional branching, branch logic, and jump logic interchangeably for it. The distinction shows up in the two branching types offered: conditional branching, which reroutes respondents only when a specific answer condition is met, versus unconditional branching, which moves every respondent through a fixed question order by default.

What are the different types of skip logic in a survey?

BlockSurvey offers four forms of skip logic: conditional branching, which routes respondents based on specific answer conditions; unconditional branching, the default path every respondent follows regardless of their answers; close or end, which sends a respondent straight to a completion or thank-you page; and chaining multiple surveys, which redirects a respondent from one survey into another on submit.
