About Logic

If your project includes multiple  pages, it's possible that not all of them apply to every respondent taking your survey. Logic allows you to create customised paths for your survey participants, based on the answer selections they make. It can also be used to disqualify people who do not fit the criteria for your research, or those who do not give consent for their data to be processed.

Note: Logic does not work by hiding/showing sets of questions on page, but rather determining which page to send respondents to based on what answers they do/don't select.

Default Logic

Default Logic (formally known as Page Logic) concerns where a respondent is sent once they click the 'Next Page' button. It's only really used when Question Logic is already being employed.

By default, it will send respondents to the next chronological page (the one placed directly after it in the  Manage Pages menu), but can be set to send respondents to any page that exists AFTER the page they're currently on.

Question Logic

Question Logic works by filtering respondents to separate pages based on the answer selections they've made. 

Note: This feature requires some planning, and should be written out on paper before constructing an online survey. 

Qualification Questions

By applying Logic in this way, you can disqualify participants from completing your survey based on any information they give you. This is particularly useful if you only want to collect results from a target audience or focus group, as you’ll avoid sifting through piles of irrelevant data. Respondents will also appreciate this, as they won’t be wasting time filling out a survey where their results aren’t useful.

Consent Pages

Consent Pages work similarly to Qualification Questions, as you’d essentially be disqualifying all those who do not give consent. We would suggest that you include this page at the beginning of your survey, to avoid wasting the time of your respondents or gathering data you won’t need.

Information Request Forms

Equally, you could use Logic to supply respondents with methods of providing further information regarding an answer option they’ve selected. E.g. if the purpose of your survey is to collect customer feedback, you would include a question such as ‘were you happy with our level of service?’. If the customer was to say ‘no’, you may want more information regarding their experience and how your service could improve. You can use Logic to direct those ‘customers’ to a page created for that specific purpose.


Logic incorporates an element of intelligence into your project; which ultimately saves your respondents time in completing your survey, and saves you time in filtering out respondents that would provide irrelevant data. Using logic is likely to increase the completion rate of your project, as respondents will only see pages which are relevant to them, and are less likely to leave before finishing.
